My PC Wi-Fi randomly works and then stops working. Sometimes it connects normally and receives a `192.168.0.x` IP address from my router, but other times it receives a `169.254.x.x` address or no IPv4 address at all, resulting in no internet connection.

From what I understand, the `169.254.x.x` address means Windows is failing to receive a proper IP address from the router through DHCP. The Wi-Fi itself still shows as connected with a strong signal, but the PC sometimes does not receive a valid IPv4 address or default gateway.

Other devices, including my phone, connect to the same Wi-Fi without any problems. My PC also works normally when connected to my phone's hotspot.

PC specifications

* **OS:** Windows 11 Home, Version 25H2 * **OS Build:** 26200.9168 * **CPU:** Intel Core i5-10400F @ 2.90 GHz * **RAM:** 32 GB * **GPU:** NVIDIA GeForce GTX 1660 SUPER, 6 GB * **Wi-Fi adapter:** Intel Wi-Fi 6 AX201 160MHz * **System type:** 64-bit operating system, x64-based processor

Symptoms / errors

When working normally:

IPv4 Address: 192.168.0.xxx Default Gateway: 192.168.0.1 

When the problem occurs:

IPv4 Address: 169.254.x.x Default Gateway: blank 

Sometimes the Wi-Fi remains connected but Windows does not receive any IPv4 address.

Troubleshooting already tried

* Disabled "Allow the computer to turn off this device to save power" * Reset Winsock using `netsh winsock reset` * Reset TCP/IP using `netsh int ip reset` * Used `ipconfig /release` and `ipconfig /renew` * Flushed DNS * Reset Windows network settings * Forgot and reconnected to the Wi-Fi * Restarted the PC multiple times * Restarted and factory reset the router * Tried manually assigning an IP address * Tested connectivity to [`192.168.0.1`](http://192.168.0.1) and [`8.8.8.8`](http://8.8.8.8) * Checked the Intel AX201 adapter in Device Manager

The issue is intermittent. Sometimes `ipconfig /renew` successfully gives me a `192.168.0.x` address, but later it can return to a `169.254.x.x` address or have no IPv4 address after restarting.

Could this be caused by the **Intel AX201 driver, Windows 11, DHCP/router settings, or failing Wi-Fi hardware**? What would you recommend trying next?
