10 “Best” 5GHz Wi-Fi Channels
The idea of listing the “10 best channels for 5GHz Wi-Fi” is tempting — fast, simple, satisfying. But it’s also misleading. The best 5GHz channel for you depends on your goals, your building materials, your neighbors, and even your proximity to radar systems.
We answer the real questions:
- Which channels are fastest — and why?
- Which ones are most stable in urban or apartment conditions?
- When does a wide 160 MHz channel backfire?
- Why can Channel 36 cause problems even though it’s “safe”?
- And why is Channel 165 both a gem and a trap?
🔑 Quick Takeaways
| ❓ Question | ✅ Expert Short Answer |
|---|---|
| What’s the safest set-and-forget 5GHz channel? | Channels 149, 153, 157, 161 — high-power, non-DFS, and compatible with all devices. |
| What’s the best for raw speed in a clean RF zone? | Channel 106 (DFS, 80 MHz) — if you’re far from airports and using a good mesh system. |
| What channel should urban users stick to? | 20 MHz on 44 or 153 — narrow width avoids collisions and keeps speed stable. |
| Is 160 MHz worth it? | Usually not on 5GHz — all 160 MHz options require DFS and are radar-prone. |
| Best width-to-speed ratio for homes? | 40 MHz — great throughput, manageable interference, and doesn’t eat up the spectrum. |
| Most misunderstood channel? | Channel 165 — high power, no DFS, but limited width (20 MHz max) and poor range. |
📡 1. Want Speed? These Are the Real Fast Lanes of the 5GHz Spectrum
To unlock top-end Wi-Fi speeds, you need channel width and low interference. DFS channels — while risky — often have the clearest airspace.
⚡ Best 5GHz Channels for Speed (in Low-Radar, Clean Zones)
| 🔢 Channel | 🧭 Band | 📶 Width Potential | ⚠️ DFS Required? | 🚀 Why It’s Fast |
|---|---|---|---|---|
| 106 | U-NII-2C | Up to 80 MHz | ✅ Yes | Sits in a clean DFS zone with minimal congestion |
| 122 | U-NII-2C | Up to 80 MHz | ✅ Yes | Wide bandwidth, fewer overlapping networks |
| 155 | U-NII-3 | Up to 80 MHz | ❌ No | High-power non-DFS option, great for range & speed |
| 58 | U-NII-2A | Up to 80 MHz | ✅ Yes | Less traffic, DFS keeps neighbors away |
| 42 | U-NII-1 | 80 MHz only | ❌ No | Safe and wide—but often saturated in apartments |
💡 Pro Tip: Before switching to DFS channels like 106 or 122, use a Wi-Fi analyzer to check for radar triggers. Otherwise, your “fast” channel could disappear mid-Netflix.
🧱 2. Living in an Apartment? Go Narrow to Go Smart
In condos and dorms, your biggest enemy isn’t speed — it’s interference. A neighbor’s wide 80 MHz network on Channel 36 can wipe out your entire U-NII-1 zone. The trick? Use 20 MHz channels, spread out, and avoid overlap.
🏢 Best Channels for Urban Wi-Fi Survival
| 📡 Channel | ⚙️ Width | 🚫 Why It Works |
|---|---|---|
| 44 | 20 MHz | Less commonly used than 36/40, avoids overlap |
| 153 | 20 MHz | Non-DFS, high-power, usually quieter than 149/157 |
| 165 | 20 MHz ONLY | Extremely low congestion — but limited speed + device support |
| 48 | 20 MHz | End of U-NII-1 — best used when neighbors avoid DFS entirely |
🎯 Urban Optimization Rule: More speed ≠ better speed. Use narrow channels to dodge neighbors. What you lose in raw Mbps, you gain in consistent streaming and gaming.
📏 3. Width Can Kill: Don’t Get Fooled by the “160 MHz” Trap
Router boxes scream “160 MHz!” like it’s a rocket boost. But on 5GHz in the U.S., it’s usually a mistake. Every 160 MHz configuration uses DFS channels — making them prone to sudden disconnection.
⚠️ Why 160 MHz Is Rarely a Good Idea
| 🎛️ Width | 🔥 Noise Floor Penalty | 🔍 DFS Exposure | 🧠 Real-World Result |
|---|---|---|---|
| 40 MHz | +3 dB | Optional | Stable with good throughput in most homes |
| 80 MHz | +6 dB | Optional or DFS | Best for fast internet if there’s space |
| 160 MHz | +9 dB | Required (always) | Risky. Fast when stable, but disconnects are likely |
🧠 Expert Math: A 160 MHz channel has 4× the bandwidth, but 9 dB more noise floor, which lowers the signal-to-noise ratio (SNR) for all clients. That means slower, not faster speeds for devices farther from the router.
🌪 4. Channel 165: High Power or High Risk?
Channel 165 is the top of the spectrum — immune to DFS, high-power capable, and often deserted. But it only supports 20 MHz, and some older devices can’t even see it.
📊 Channel 165: Strategic Snapshot
| 📡 Feature | ⚠️ Impact |
|---|---|
| Max Width | 20 MHz only — limits speed potential |
| Device Compatibility | Some IoT and legacy clients can’t detect it |
| Interference | Very low — few routers use it |
| Ideal Use Case | Rural/remote installs, or a dense urban fallback channel |
🧪 Tactical Use: Use Channel 165 for IoT segregation, backup SSIDs, or when everything else fails.
🛡 5. Want a Stable Network? These Channels Are Set-and-Forget Gold
If you stream, Zoom, or game from home — you want a channel that won’t suddenly vanish due to radar detection. That means no DFS, moderate width, and high client compatibility.
🧱 Best “Safe Harbor” Channels (No DFS, Stable, Fast)
| 🔢 Channel | 🌐 Band | 🧱 Why It Works |
|---|---|---|
| 149 | U-NII-3 | High power, wide support, often underutilized |
| 153 | U-NII-3 | Pairs well at 40 MHz (151), works with most devices |
| 157 | U-NII-3 | Great for shorter ranges, stable across Wi-Fi 5/6 |
| 161 | U-NII-3 | Cleanest of the group — furthest from busy U-NII-1 |
| 44 | U-NII-1 | Mid-range, safe from DFS, often quieter than 36/40 |
🧠 Channel 155 (80 MHz, U-NII-3) is your best high-speed, non-DFS option — but only if nearby routers aren’t hogging that band.

✅ Summary: The “10 Best Channels” Is a Myth — This Is the Real Strategy
There’s no universal top 10. But there are tactical wins, hidden gems, and dangerous traps depending on your home, your neighborhood, and your tech stack.
- 🏡 Most Homes: Use Channel 155 (80 MHz, non-DFS) or 46 (40 MHz, non-DFS) for a stable + fast setup.
- 🏢 Apartments: Use 44 or 153 at 20 MHz, prioritize clean air over speed.
- 🌲 Rural Speed Demons: Try Channel 106 (80 MHz, DFS) — with monitoring.
- 🤖 Smart Homes: Use 165 as a fallback for 20 MHz-only devices.
- 🎯 Everyone Else: Stick with non-DFS, 40 MHz width, and scan often.
FAQs
🧠 “Why does my router switch channels randomly even when I’ve set it manually?”
Your router might be switching because you’ve selected a DFS channel. Even with manual configuration, DFS rules override user settings when radar interference is detected. This triggers automatic evacuation, forcing your router to immediately abandon the current channel and jump to a backup — typically one it chooses itself. Most routers do not return to the original DFS channel after the mandatory 30-minute quiet period. The only way to fully control stability is by using non-DFS channels like 149, 153, or 157.
| ⚠️ Symptom | 🔍 Hidden Cause | ✅ Solution |
|---|---|---|
| Manual channel keeps changing | DFS radar detection overrides it | Use only U-NII-1 or U-NII-3 channels |
| Channel changes after reboot | Channel Availability Check (CAC) resets | Avoid DFS; disable DFS-only bonding widths |
| Devices disconnect briefly | In-service radar event triggers evacuation | Check logs or use router that logs DFS |
🔄 “I upgraded to a tri-band router, but my speeds got worse. What gives?”
Tri-band doesn’t guarantee faster speed — it adds another 5GHz band, but default settings often auto-assign clients poorly. The issue likely lies in client steering, where the router fails to intelligently allocate devices across available radios. One band may get overloaded while the other sits idle. Also, tri-band routers sometimes place one 5GHz band on DFS-only channels, increasing instability.
Fixing it requires manual control:
- Assign separate SSIDs to each band and distribute clients manually.
- Lock one 5GHz radio to channel 42 or 155 and the other to a DFS like 106, if you’re willing to monitor stability.
- Use band steering logs or router analytics to track load balance.
📉 “Why is my 5GHz network slower than 2.4GHz in certain parts of my house?”
This is a classic case of signal attenuation over distance. While 5GHz can support higher speeds, it suffers far more from obstruction and wall penetration losses compared to 2.4GHz. The physics are unforgiving: shorter wavelengths (5GHz) are absorbed more by concrete, wood, and even drywall.
To quantify:
- 5GHz signal drops by 6–9 dB for every wall.
- SNR (Signal-to-Noise Ratio) may degrade to a point where modulation schemes fall back from 256-QAM to 64-QAM or worse, slashing throughput.
- Meanwhile, 2.4GHz holds its ground with lower bandwidth but more forgiving propagation.
| 🔎 Location Factor | 📶 Effect on 5GHz | 🔄 Optimization Tip |
|---|---|---|
| One wall between device and AP | 10–15% signal degradation | Try switching to 40 MHz for better SNR |
| Multiple walls or floor between | 40–60% loss of throughput | Use a mesh node or place AP mid-home |
| Same room as router | Peak 5GHz performance possible | Stick with 80 MHz and test DFS if congestion-free |
🎯 “What’s the real-world impact of using 80 MHz vs 40 MHz on battery life for phones?”
The difference is surprisingly non-trivial. Using 80 MHz channels leads to more rapid modulations, higher transmit power, and frequent retries in marginal signal areas. That means client devices must work harder to decode and maintain link quality, especially if SNR is low.
Empirical field testing shows:
- 40 MHz channels offer a 15–20% longer battery life in daily use (especially on Android devices).
- 80 MHz only outperforms when you’re within 15 feet of the router with unobstructed line-of-sight.
- On iPhones, background Wi-Fi scans on wide channels are more aggressive, especially during location services and Wi-Fi Assist, accelerating drain.
For phone-heavy households, especially with mixed-generation devices, a balanced 40 MHz setup on a clean U-NII-3 channel can result in better overall experience and longer uptime.
📡 “Can I use Channel 165 with a 40 or 80 MHz width?”
No — Channel 165 is limited to 20 MHz only under FCC rules. Its center frequency sits at 5825 MHz, and there’s no adjacent channel space above it to support bonding. This makes Channel 165 both a blessing and a limitation:
- ✅ It’s non-DFS, high-power, and nearly always empty.
- ❌ But it supports only legacy speeds, and some devices (like certain smart TVs, older Androids) may not recognize it.
Ideal use case?
Smart home hubs, IoT security cameras, or legacy Wi-Fi 4 devices that operate in 5GHz but don’t support wide channels.
🧪 “Can overlapping with neighbors actually slow down BOTH networks?”
Absolutely — and it’s not just signal interference, it’s channel contention. Two overlapping networks on the same or partially overlapping channels (like 40 MHz on 38 and 46) must share airtime through a Carrier Sense Multiple Access (CSMA/CA) protocol. That means:
- Devices must “listen” before they “talk”.
- When they detect nearby transmissions, they back off — this adds latency, increases jitter, and lowers throughput.
- Collisions can lead to retransmissions, killing speed for everyone.
| 🔁 Overlap Type | ⚠️ Effect on Performance | 🛠️ Best Practice |
|---|---|---|
| Co-channel (same freq) | Max contention, low throughput for both | Move to a distant, non-overlapping 20 MHz slot |
| Adjacent channel | Interference without coordination | Reduce width or scan for valleys between users |
| DFS + non-DFS mix | One may evacuate suddenly, causing instability | Avoid mixing channel types in shared airspace |
💼 “Which channel plan works best for a mesh network?”
For mesh systems, the backhaul channel — the one used between nodes — must be rock-solid and preferably uncongested. Most modern mesh kits use 5GHz for backhaul, so:
- Use U-NII-3 band (149–161) for a non-DFS, stable backhaul.
- Set client-facing SSID to U-NII-1 band (36–48) to reduce contention between access and backhaul paths.
- If tri-band, assign a dedicated radio to DFS channels (e.g., Channel 106) for backhaul if you live far from radar sources.
This tiered configuration provides clean isolation between network layers, maximizing client throughput and mesh stability.
🏙️ “Why is my Wi-Fi slower at night even though I’m using a non-DFS channel?”
This is a textbook example of time-based environmental congestion. Even when using clean U-NII-1 or U-NII-3 channels, your neighbors are likely using the same ‘safe’ bands, especially during peak residential hours (6 PM to 11 PM). Wi-Fi is a shared medium — airtime is finite.
At night:
- More TVs stream 4K content.
- Work-from-home gear, like VoIP phones, may go into standby sync mode.
- Smart homes begin backup, upload, or cloud sync routines.
Unlike interference, which distorts the signal, congestion starves airtime, delaying frames and causing retransmissions even on strong signal links.
| 🌃 Peak Hour Phenomenon | 🧠 Why It Happens | ✅ Expert Tip |
|---|---|---|
| Slower speeds in evenings | Competing traffic from multiple nearby networks | Switch to a less common 40 MHz width |
| Stable mornings, laggy nights | Neighboring APs ramp up usage after work hours | Use a Wi-Fi analyzer during peak times |
| Clean signal but poor performance | Airtime saturation, not interference | Enable bandwidth QoS per device |
🔁 “Should I disable 2.4GHz if I’m using only 5GHz devices?”
Not always. Although 5GHz offers cleaner spectrum and faster throughput, some critical functions still rely on 2.4GHz’s superior range and wall penetration. Consider:
- Smart home devices (like plugs, bulbs, thermostats) often only support 2.4GHz.
- 2.4GHz has lower path loss, useful for basements, garages, or detached spaces.
- Mesh systems often use 2.4GHz for resilient failover when 5GHz degrades.
If all your devices are confirmed dual-band, and you’ve tested RSSI (Received Signal Strength Indicator) across every corner of your property, you can experiment with disabling 2.4GHz temporarily. But beware of “band-edge” devices: those at the edge of your coverage map that silently fall back to 2.4GHz when 5GHz becomes too noisy.
🔐 “Does hiding the SSID improve security or performance?”
Hiding the SSID (network name) does not enhance real security. Wireless packets still broadcast SSID in probe responses, making it trivial for any attacker with Wi-Fi scanning tools to identify hidden networks.
It can, however, cause connectivity headaches:
- Devices may constantly probe for hidden networks, draining battery.
- Roaming becomes less efficient, especially in mesh or enterprise setups.
- IoT devices often struggle to connect or re-authenticate.
For real security:
- Use WPA3 if available, or WPA2 with a strong passphrase.
- Disable WPS (Wi-Fi Protected Setup) to prevent brute-force PIN exploits.
- Isolate IoT gadgets on a guest or VLAN-separated network.
📶 “Why does my smart TV lag even though speed tests show 300 Mbps on my phone?”
Smart TVs often use legacy Wi-Fi chipsets, prioritizing power efficiency over performance. Also, they may default to 2.4GHz or latch onto an overloaded band. A phone with MU-MIMO and beamforming gets better airtime than a TV with a single-antenna 802.11n chipset.
Additionally:
- TVs are often placed in media cabinets, which attenuate RF.
- Streaming apps use adaptive bitrate streaming, but initial buffering lags if packet jitter is high.
Run a local throughput test on the TV using apps like Netflix Fast Test or Plex internal bandwidth meters to assess actual sustained rate, not just broadband speed.
| 📺 Problem | 🧩 Underlying Cause | 🛠️ Actionable Fix |
|---|---|---|
| 4K video buffers randomly | TV stuck on 2.4GHz, poor chipset | Force connect to 5GHz using static IP or manual SSID split |
| Speed test on phone is great, TV lags | Airtime fairness or beamforming bias | Assign TV to low-congestion 5GHz channel manually |
| No issues on wired devices | Wi-Fi signal fluctuations | Add a wired backhaul or media-optimized extender |
🧭 “What’s the best channel for gaming on 5GHz?”
There’s no universal “best” channel — but for low-latency gaming, you must prioritize channel cleanliness and stability. This means:
- Avoid DFS entirely to reduce unexpected drops.
- Use a 40 MHz non-DFS width to maintain stable SNR without congestion.
Top-performing gaming channels (in the U.S.):
- Channel 38 (bonded 36+40)
- Channel 46 (bonded 44+48)
- Channel 151 or 159 in the U-NII-3 band, often cleaner due to higher frequency edge.
Avoid 80 MHz channels unless you’ve measured very low noise and neighboring activity, as they are more vulnerable to fluctuating latency and jitter.
🌐 “Should I use the same SSID for 2.4GHz and 5GHz?”
This practice, called band steering, works well only if the router supports smart band management. Without it, some devices will randomly choose 2.4GHz, even when 5GHz is stronger.
Split SSID Pros:
- Manual control of which band each device uses.
- Easier troubleshooting.
Unified SSID Pros:
- Cleaner interface for guests.
- Automatic load balancing (if properly supported).
Recommendation:
- Split SSIDs during diagnostics or in high-interference environments.
- Reunify after optimizing AP placement and band rules.
🧬 “Can adjusting TX power improve performance or reduce interference?”
Yes — in fact, transmit power (TX) misconfiguration is one of the most overlooked causes of interference and coverage imbalance.
Key considerations:
- Too high = more interference, not better signal. You bleed into other channels and confuse roaming clients.
- Too low = coverage holes, especially if client TX power is higher (asymmetric link).
Ideal strategy:
- Lower TX power on 5GHz if using multiple APs to encourage cleaner roaming boundaries.
- Match TX power between 2.4GHz and 5GHz to avoid sticky clients.
- Adjust per room size — not all APs need to blast at full capacity.
| ⚙️ TX Power Level | 🎯 Best Use Case | 🧠 Impact Summary |
|---|---|---|
| High (20-23 dBm) | Large open spaces, long halls | More coverage, more channel bleed |
| Medium (14-17 dBm) | Standard rooms or multi-AP homes | Balanced reach and roaming |
| Low (8-12 dBm) | Small offices, apartments with shared walls | Reduces conflict, improves neighbor coexistence |
⚙️ “What does ‘channel bonding overlap’ mean and why is it bad?”
Channel bonding overlap occurs when a router combines adjacent 20 MHz channels (e.g., to form a 40 or 80 MHz bandwidth), but the combined range intersects with another network’s bonded or unbonded signal.
It’s not simply overlapping signals—it’s overlapping spectrum usage, which causes:
- Backoff delays due to Wi-Fi’s “polite” protocol (CSMA/CA).
- Hidden node problems, where routers can’t hear each other but interfere anyway.
- Amplified contention that destroys throughput on both networks.
For example, two networks using 80 MHz widths—one on channel 42 (36–48), another on 46 (44–56)—will overlap partially, leading to signal collisions and degraded modulation.
| 💥 Overlap Type | 🔎 Symptoms | 🛠️ Avoidance Strategy |
|---|---|---|
| Full (Same center freq) | Dropped packets, jitter | Change channel center to non-overlapping |
| Partial (Adjacent range) | Poor speed despite strong signal | Reduce to 40 MHz and rescan RF environment |
| DFS/non-DFS conflict | Random disconnects, evacuations | Keep bonded widths within safe zones |
📲 “Why do newer phones get faster speeds than laptops in the same room?”
This is the result of client-side Wi-Fi stack disparities, antenna design, and protocol support. Newer phones (especially flagship Android and iPhones) have:
- Optimized thermal budgets, allowing more aggressive modulation schemes (e.g., 1024-QAM).
- Built-in 2×2 or 4×4 MIMO antennas.
- Faster support for multi-user OFDMA (Wi-Fi 6) and beamforming.
Many laptops, even newer ones, still use older Intel Wi-Fi cards, often limited to 1×1 or 2×2 spatial streams and lack MU-MIMO reception. Moreover, mobile OSes prioritize Wi-Fi performance more aggressively for cloud syncing, backups, and HD streaming.
| 📱 Device Class | ⚡ Wi-Fi Chip Capability | 🔍 Speed Impact |
|---|---|---|
| iPhone 14 Pro / S24U | Wi-Fi 6E, 4×4 MU-MIMO, beamforming | Peaks at >900 Mbps |
| MacBook Air M1 | Wi-Fi 6, 2×2 MU-MIMO | Averages 500–700 Mbps |
| Budget Windows Laptop | Wi-Fi 5 (802.11ac) 1×1 card | Peaks at 250 Mbps |
🧩 “How can I tell if my neighbor’s Wi-Fi is killing my performance?”
The easiest way is to analyze airtime saturation and channel overlap using a 5GHz Wi-Fi analyzer. Apps like inSSIDer, NetSpot, or WiFi Explorer show:
- Channel width and center frequency of all nearby SSIDs.
- RSSI (signal strength) values of neighbors’ signals at your location.
- Whether neighboring networks are bonded across your selected spectrum.
Even if your signal is stronger, if neighbors occupy overlapping spectrum, your devices will compete for airtime. This is particularly painful for:
- Online games
- Zoom calls
- Real-time file transfers
| 🧪 Signal Reading | 🚨 Interference Indicator | 🧠 Interpretation |
|---|---|---|
| Neighbor at -60 dBm or better | Definitely impacting shared channels | Move to non-overlapping 40 MHz band |
| Channel overlap >40 MHz | Shared airtime and backoff collisions | Reduce bonding width and reassign manually |
| Multiple SSIDs on same channel | Likely from dual-band or guest network | Re-scan and shift to unused spectrum zone |
🧠 “Why does switching to 80 MHz drop speeds in other rooms?”
This happens because wide channels require higher SNR to maintain modulation efficiency. When you use 80 MHz:
- You quadruple your spectrum usage, but also triple your noise floor (9 dB higher than 20 MHz).
- In distant rooms, walls and floors reduce your SNR below the thresholds needed for high-order QAM.
- Wi-Fi then fallbacks to more resilient but slower encoding, often below what a 40 MHz or 20 MHz channel could’ve maintained.
The paradox: Wider isn’t faster in low-signal conditions.
| 🧱 Distance from AP | 📶 SNR with 80 MHz | 🚀 Recommended Width |
|---|---|---|
| Same room (0–1 wall) | Excellent (>35 dB) | 80 MHz (max speed zone) |
| 1–2 walls | Moderate (25–30 dB) | 40 MHz (best balance) |
| >2 walls or upstairs | Poor (<20 dB) | 20 MHz (more stable connection) |
🧪 “Why does my mesh system slow down when more devices connect?”
Mesh systems rely heavily on shared backhaul bandwidth. As more devices connect:
- The available airtime for client communication decreases.
- Devices compete on both the client-facing and backhaul links.
- If your system uses a dual-band architecture, both functions often occur on the same 5GHz channel — leading to contention loops.
Performance nosedives when:
- The router and node both use Channel 42 at 80 MHz.
- Several devices on both nodes attempt simultaneous high-throughput tasks.
The fix? Use a tri-band system or:
- Dedicate one 5GHz band to backhaul (U-NII-3).
- Limit client-to-node association with roaming thresholds.
🌪️ “Do weather or appliances affect 5GHz performance?”
Yes — although 5GHz is less vulnerable than 2.4GHz, certain conditions still degrade it:
- Microwave ovens can leak interference up to 5.8 GHz, affecting U-NII-3 channels like 157–165.
- TDWR radar near airports can disrupt DFS channels in the U-NII-2C band (100–144).
- Heavy rain or humidity doesn’t directly block Wi-Fi, but can increase reflection and absorption, slightly degrading long-distance signals.
| ⚠️ Environmental Factor | 📉 Affected Channels | 🧠 Impact Summary |
|---|---|---|
| Microwave oven active | 157–165 (U-NII-3) | Short-range disruption, jitter spike |
| Radar proximity (airport) | 100–144 (DFS) | Forced evacuation, blacklisted channels |
| Humidity / dense walls | All >5GHz | Attenuation worsens with channel width |
💬 “How can I stop my router from defaulting back to Auto channel?”
Some routers re-enable Auto mode after:
- Firmware updates
- Reboots or power loss
- DFS-triggered evacuations without a stable fallback
To lock it:
- Choose a non-DFS fixed channel (e.g., 153 or 46).
- Disable auto-width and auto-band steering in advanced settings.
- On mesh systems, check if the controller overrides satellite APs.
For business-grade routers (e.g., UniFi, Aruba):
- Use a custom channel plan profile.
- Enforce via policy instead of per-radio.
| 🔧 Router Setting | 🔒 Lock Behavior | 💡 Recommendation |
|---|---|---|
| Auto channel: OFF | Manual override, stable channel | Select non-DFS to avoid radar overrides |
| Auto bandwidth: OFF | Fixes width to 40 or 80 MHz | Improves control over modulation/SNR balance |
| Smart connect / band steer: OFF | Prevents forced 2.4GHz switch | Allows manual band targeting by SSID |
