How to Fix WiFi 6 160 MHz Channel Width Not Working: Enabling Wide Channels on Windows, Android, and Your Router

WiFi 6 (802.11ax) can theoretically deliver over 1.2 Gbps on a single 5 GHz stream — but only when using a 160 MHz channel width. Most routers default to 80 MHz, cutting that ceiling in half. And even after you enable 160 MHz on your router, Windows laptops with Intel AX200 or AX201 adapters frequently negotiate down to 80 MHz due to driver settings or DFS channel behavior. This guide walks through every layer of the fix: router, Windows, and Android. Before and after each change, run a WiFi speed test so you can measure the actual gain.

Why 160 MHz Is Disabled by Default

On the 5 GHz band there are only two contiguous 160 MHz blocks available: channels 36–64 and channels 100–128. Both overlap with DFS (Dynamic Frequency Selection) spectrum — frequencies shared with weather radar and military systems. Routers operating on DFS channels must scan for radar signals before transmitting, which causes a 1–10 minute “DFS scan delay” on first boot. If radar is detected, the router must immediately vacate the channel, causing a brief disconnection. Because of this, most manufacturers ship with 160 MHz off or locked to 80 MHz to avoid support calls from users wondering why their router takes ten minutes to come online.

The tradeoff is real: if you live near an airport, military base, or weather station, DFS events can interrupt your connection several times per day. In most suburban and urban homes, however, DFS events are rare and 160 MHz is worth enabling.

Step 1: Enable 160 MHz on Your Router

Log into your router’s admin panel (typically 192.168.1.1 or 192.168.0.1) and navigate to the Wireless or WiFi settings for the 5 GHz band. The exact path varies by brand:

• ASUS: Wireless → General → 5 GHz tab → Channel Bandwidth → select 20/40/80/160 MHz
• TP-Link (Archer / Deco): Advanced → Wireless → 5 GHz → Channel Width → 160 MHz
• Netgear: Advanced → Advanced Setup → Wireless Settings → Channel Width → 160 MHz
• Eero / Google Nest: These apps manage channel width automatically and do not expose a manual 160 MHz toggle — skip to the Windows and Android steps below.

After changing the setting, save and allow the router to restart. Expect a 1–5 minute delay before the 5 GHz radio comes back online while it completes its DFS scan. Also update your router firmware before making this change — several early WiFi 6 firmware versions had bugs that caused 160 MHz to drop connections intermittently.

Enable DFS If Required

Some routers have a separate DFS toggle that must be enabled before 160 MHz becomes available. On ASUS routers look for Enable 160 MHz under the Wireless → Professional tab. On D-Link WiFi 6 routers, 160 MHz is labeled as requiring DFS and is not available by default in all regions. If you do not see 160 MHz in the channel width dropdown, check whether a “DFS channels” or “Enable 160 MHz” option exists elsewhere in the wireless advanced settings.

Step 2: Fix 160 MHz on Windows (Intel AX200, AX201, AX210)

Intel’s WiFi 6 adapters — the AX200, AX201, and AX210 — ship with a driver-level restriction that can prevent them from using 160 MHz even when the router broadcasts it. The fix is in Device Manager.

1. Press Win + X and open Device Manager.
2. Expand Network Adapters and double-click your Intel WiFi adapter.
3. Go to the Advanced tab and find 802.11ax HT160 Support or Channel Width for 5GHz.
4. Set the value to Auto or 160 MHz depending on which options appear, then click OK.

If neither option exists in your adapter’s Advanced tab, your driver version is likely too old. Download the latest Intel WiFi driver directly from Intel’s website (search “Intel Driver & Support Assistant”) rather than relying on Windows Update, which often lags months behind. After installing the new driver, recheck the Advanced tab — the 160 MHz option appears in driver version 22.x and later.

Verify the Connection Width

Open a command prompt and run netsh wlan show interfaces. Look for the Receive rate and Transmit rate fields. A 160 MHz connection with one spatial stream on WiFi 6 shows roughly 1,201 Mbps; an 80 MHz connection shows around 600 Mbps. If you still see 600 Mbps or lower after the driver change, the adapter is still negotiating 80 MHz — try disconnecting and reconnecting to the network, or reboot the PC with the router already running on 160 MHz.

Step 3: Android and 160 MHz

Android does not expose a manual channel-width selector to users. Whether a phone uses 160 MHz depends entirely on the chipset and the phone manufacturer’s WiFi driver. Qualcomm Snapdragon 865, 888, 8 Gen 1, and later flagships support 160 MHz; many mid-range phones are capped at 80 MHz regardless of the router setting. There is no setting to change.

What you can do to maximize the chance your Android phone uses 160 MHz:

• Stay within 15–20 feet of the router. 160 MHz requires a strong signal; at longer ranges the adapter falls back to narrower widths automatically.
• Forget the network and reconnect after enabling 160 MHz on the router — the new channel width may not take effect on an existing connection.
• Check for a phone software update. Some manufacturers have shipped driver fixes that enable 160 MHz support via OTA update.
• Use a WiFi analyzer app (e.g., WiFi Analyzer by farproc) to confirm your router is actually broadcasting on a 160 MHz channel before assuming the phone is the bottleneck.

When 160 MHz Causes More Problems Than It Solves

160 MHz is not always the right setting. Consider staying at 80 MHz if:

• You experience frequent brief disconnections after enabling it (DFS radar events in your area)
• Devices further from the router see lower speeds at 160 MHz than at 80 MHz — wider channels are more sensitive to interference and noise at range
• You have many clients and a mesh system: 160 MHz can reduce concurrent airtime efficiency in dense environments

For a single high-performance device like a gaming PC or a laptop used close to the router, 160 MHz is almost always beneficial. For a whole-home mesh covering three floors, 80 MHz may deliver better aggregate throughput across all devices. See our guide on WiFi channel width explained for a deeper look at the tradeoffs.

Quick Checklist

• Router firmware up to date before enabling 160 MHz
• Router channel width set to 160 MHz (or 20/40/80/160 auto) in 5 GHz settings
• DFS toggle enabled if 160 MHz doesn’t appear in the dropdown
• Intel adapter: Advanced tab in Device Manager → 802.11ax HT160 or Channel Width set to Auto/160 MHz
• Intel driver updated to version 22.x or later
• Verify with netsh wlan show interfaces — link rate should be ~1,201 Mbps
• Android: forget and reconnect network, stay close to router
• Run a speed test to confirm the improvement

Once you have 160 MHz working end-to-end, a WiFi 6 laptop close to the router should consistently exceed 700–900 Mbps on a real-world speed test — roughly double what 80 MHz delivers. For the routers that handle 160 MHz most reliably, see our roundup of the best WiFi 6E routers, many of which use the cleaner 6 GHz band where 160 MHz is available without DFS complications.
