Dell XPS 15 9510 Windows 22H2 (22621.1485).

This problem has persisted through multiple Windows 11 updates and multiple Dell driver updates.

About half the time when I boot my laptop up at work, the wifi connection just says "No internet". It says it's connected to the correct wifi. Initially, I would just use the guest wifi or reboot a couple times until it worked. After finally digging, I've realized what is happening. The TCP/IP4 settings are changing to this somehow:

I simply change it to DHCP and it starts working. However, the next day there's about a 50% chance it will do it again. This is regardless of whether I shut down or just "sleep".

    Run DISM / SFC, restart and see if that helps. ...... (1) Open cmd.exe with Run as Administrator. (2) DISM.exe /Online /Cleanup-image /StartComponentCleanup (3) DISM.exe /Online /Cleanup-Image /Restorehealth (4) SFC /SCANNOW (5) Restart when all the above is complete and test.

  • Have you installed an antivirus (not Windows Defender) ? Commented Apr 4, 2023 at 14:57

    Check with IT staff at work -- they may have implemented a Group Policy or network setting causing the issue. Commented Apr 4, 2023 at 18:21
  • No new antivirus installations. No new group policies or network changes. I'll try all the DISM and SFC commands and see how it goes. Commented Apr 4, 2023 at 19:20
  • It happened again this morning when I signed in. So none of the DISM or SFC tricks helped. I did notice "bridge driver" was enabled. The connection was NOT bridged, but I unchecked the bridge driver to see if that helps. ¯\_(ツ)_/¯ Commented Apr 6, 2023 at 14:13

I've run with the same issue on Windows 10 22H2. After assigning IP details manually on the Ethernet port it showed blank settings just the same way as on the picture in this post. Network reset didn't help, however after running 'ipconfig' I've discovered that coincidentally the same IP was assigned on the WiFi adapter. Thus, after assigning IP details from another subnet, the IP settings were saved successfully.

  • Our office needs manual IP settings (long story). So my new Windows 11 machine kept forgetting my IP settings for ethernet, set manually. It would either forget all settings or today it just forgot the gateway-address. Bah. I looked: so far I had not yet used Wifi on this new machine. So that was still set to DHCP. I have a list for all machines. So I set the Wifi to manual now and entered the correct addresses, which do not conflict with any other machine on this network. Will see if this helps. It would be bad, if Windows 11 dropped certains settings (because of conflicts) without telling. Commented Jan 31 at 10:36
