Quick fix: Wi-Fi 7 (802.11be) requires the latest adapter driver, an OS build of 24H2 or later, and a router with up-to-date firmware. Even with all three, the connection often negotiates as Wi-Fi 6E if Multi-Link Operation (MLO) or 320 MHz channel width isn’t enabled on the router. Confirm router settings, update Intel/Qualcomm driver, and force the band/width in adapter advanced settings.
You bought a Wi-Fi 7 laptop or installed a Wi-Fi 7 PCIe card. Your router is Wi-Fi 7 certified. But the connection shows as Wi-Fi 6 (802.11ax) in Settings → Network & internet. Speeds top out at a few hundred Mbps when the cable lab measured 2 Gbps. Something in the negotiation isn’t completing the Wi-Fi 7 handshake.
Affects: Windows 11 with Wi-Fi 7 hardware on both sides.
Fix time: 20 minutes.
What makes a connection “Wi-Fi 7”
Wi-Fi 7 isn’t a single switch — it’s the combination of three features: 320 MHz channel width in the 6 GHz band, 4096-QAM modulation, and Multi-Link Operation (transmitting on multiple bands at once). Most current Wi-Fi 7 deployments aren’t using all three. A connection that uses only some Wi-Fi 7 features still reports as 802.11be, but the headline speed numbers don’t materialize without all three.
Common reasons for falling back to Wi-Fi 6 negotiation: router has 6 GHz disabled or set to 160 MHz instead of 320, adapter driver predates Wi-Fi 7 support, regulatory domain restricts 6 GHz channels in your region, or the router’s firmware doesn’t enable MLO yet.
Method 1: Confirm router-side Wi-Fi 7 settings
- Sign in to your router’s admin page (typically
192.168.1.1or192.168.0.1). - Go to Wireless → Wi-Fi 7 (location varies by brand).
- Confirm the following:
6 GHz band: Enabled
Channel width on 6 GHz: 320 MHz (or “Auto” with 320 allowed)
Modulation: 4096-QAM enabled
MLO (Multi-Link Operation): Enabled
Country/Region: Set to your actual country (regulatory affects available channels) - Save changes. The router may restart, taking 1–2 minutes.
- Check the firmware version. If it’s more than 3 months old, install the latest — Wi-Fi 7 firmware matures rapidly.
If MLO is greyed out or missing, your router model doesn’t support it yet. Check the manufacturer’s site for a beta firmware that adds it.
Method 2: Update the Wi-Fi adapter driver
- Identify your adapter. Press
Win + X→ Device Manager → expand Network adapters. Note the brand (Intel Wi-Fi 7 BE200, Qualcomm FastConnect 7800, MediaTek MT7925, etc.). - Download the latest driver from the chip vendor’s site, not Windows Update:
Intel:intel.com/content/www/us/en/download-center
Qualcomm: through the laptop OEM’s support page
MediaTek: through the laptop OEM - Install the driver. Reboot.
- Verify the version in Device Manager → the adapter → Properties → Driver tab. Compare to the latest published.
Wi-Fi 7 driver maturity in late 2025 is uneven — Intel BE200 had a notorious AMD compatibility issue that took several driver versions to fix. If you have an AMD-platform laptop with BE200, ensure you’re on the latest driver (4.0 or higher) where this is resolved.
Method 3: Force 6 GHz band and 320 MHz width in adapter advanced settings
- Device Manager → the Wi-Fi adapter → Properties → Advanced tab.
- Find Preferred Band. Set to Prefer 6 GHz band (or 6 GHz only if available).
- Find Channel Width for 6 GHz. Set to 320 MHz.
- Find 802.11be Mode (or Wi-Fi 7). Confirm it’s Enabled.
- Click OK. Disable and re-enable the adapter from Device Manager to force a fresh association.
- Open Settings → Network & internet → Wi-Fi → (network name) → Properties. Confirm Protocol reads Wi-Fi 7 (802.11be).
If the protocol still reads Wi-Fi 6, the chosen band isn’t Wi-Fi 7-capable in your physical environment (maybe distance from router, or 6 GHz is regulatory-restricted indoors).
How to verify the fix worked
- Settings → Network & internet → Wi-Fi → Properties shows Wi-Fi 7 (802.11be) and link speed above 1 Gbps.
- Run
netsh wlan show interfacesin PowerShell. Look at Radio type — reads 802.11be. - Run a speed test at
fast.comorspeedtest.net. Throughput should reflect your ISP speed plus Wi-Fi 7’s overhead reduction (typically 20–40% faster than the same connection on Wi-Fi 6).
If none of these work
If the connection negotiates Wi-Fi 6E but not Wi-Fi 7 despite everything matching, check whether your country’s regulator has approved the full 320 MHz channel allocation — not all regions allow it yet. In countries with only 160 MHz allocations in 6 GHz, you’ll get most Wi-Fi 7 features but the channel width caps at 160. For Wi-Fi 7 on Windows 11 21H2 or 22H2, the OS itself may not fully support 802.11be — update to 23H2 or 24H2. For laptop OEMs that ship customized Wi-Fi firmware, you may need their specific BIOS update to enable Wi-Fi 7 even after the adapter driver is current.
Bottom line: Wi-Fi 7 needs all three sides (router, OS, adapter) at current state plus regulatory permission for 320 MHz. Update each piece, force 6 GHz preference, and the negotiation upgrades. Without MLO, you still benefit from the speed and modulation improvements.
