WiFi not connecting to Home Xfinity Gateway Router

[andrewp1988]

Hello,

I am requesting assistance with a Wi-Fi connectivity issue on my HP laptop.

Product: HP Pavilion Laptop 15-eg2xxx
Operating System: Windows 11
Processor: Intel Core i7-1255U
Wireless Adapter: MediaTek MT7921 Wi-Fi 6 (802.11ax) PCIe Adapter
Driver Version: 3.0.1.1337 (Driver Date: 09/19/2025)

Problem

My laptop will not connect to my home Xfinity Wi-Fi network.

When I select my network, Windows displays "Verifying and connecting" for several seconds and then reports "Can't connect to this network."

What Works

• Ethernet connection works normally.
• Internet access works normally over Ethernet.
• The laptop connects successfully to my phone's mobile hotspot.
• The Wi-Fi adapter detects nearby wireless networks.
• Other devices (phones, tablets, etc.) connect to my Xfinity Wi-Fi without any issues.

Adapter Status

Device Manager reports:

MediaTek MT7921 Wi-Fi 6 802.11ax PCIe Adapter
Status: "This device is working properly."

The adapter temporarily disappeared after uninstalling it but later reappeared after rescanning hardware and currently shows no errors.

Router Information

• Security: WPA2-PSK (AES)
• 2.4 GHz Mode: 802.11g/n
• 5 GHz Mode: 802.11a/n/ac/ax

No recent router configuration changes were made before this issue started.

Troubleshooting Already Performed

• Restarted the laptop multiple times.
• Restarted the Xfinity gateway multiple times.
• Reset Windows network settings.
• Forgot and re-added the Wi-Fi network.
• Verified the Wi-Fi password multiple times.
• Confirmed Ethernet works.
• Confirmed mobile hotspot works.
• Disabled and re-enabled the Wi-Fi adapter.
• Uninstalled and reinstalled the Wi-Fi adapter.
• Attempted driver updates.
• Ran Windows Network Troubleshooter.
• Ran Administrator network reset commands including:
  • netsh winsock reset
  • netsh int ip reset
  • netcfg -d
• Rebooted after resets.
• Verified the Wi-Fi radio is enabled.
• Verified the adapter supports WPA2 and WPA3.
• Tested changing Advanced adapter settings including:
  • Preferred Band
  • 802.11ax
  • 802.11ac
  • 802.11n
  • U-APSD Support
• None of these changes resolved the issue.

Diagnostic Results

I ran the following commands:

• netsh wlan show interfaces
• netsh wlan show drivers
• netsh wlan show networks mode=bssid

Results show:

• Windows correctly detects the MediaTek MT7921 adapter.
• The driver loads successfully.
• The Wi-Fi radio is ON.
• The adapter scans and detects nearby wireless networks normally.
• The adapter supports both 2.4 GHz and 5 GHz networks.
• The adapter successfully connects to my phone's hotspot.
• The adapter consistently fails only when attempting to authenticate with my Xfinity Wi-Fi network.

Assistance Requested

Based on the troubleshooting completed, I would appreciate assistance determining whether this is:

• A known compatibility issue between the MediaTek MT7921 adapter and Xfinity gateways.
• A BIOS issue.
• A MediaTek driver issue.
• A firmware issue.
• A Windows networking issue.
• A hardware issue with the wireless adapter.

If applicable, please provide the latest HP-recommended BIOS, chipset, and MediaTek wireless driver for my exact model, along with any known fixes for MT7921 authentication failures with Xfinity gateways.

Thank you.
