Puzzling Debian 12 Wireless Internet Issue
by Apples555 from LinuxQuestions.org on (#6R0AT)
Hello! This is my first post, so please let me know if I am breaking any rules.
I have been using Linux for many years, mostly Debian, but I have a puzzling issue that hasn't happened before. On my desktop running Debian 12, the internet will stop working. Ping stops and downloads stop. However, the wireless connection stays connected. The only way to get internet back is to reconnect, then it's normal again. It might stay up for days, or a few minutes. It seems like activity makes it more likely to fail.
When this happens, ping says temporarily failure in name resolution. Here's what I have tried.
-Turning off power management
-Transferring to iwd instead of wpa supplicant
-Transferring to connman instead of networkmanager
-Replacing Realtek RTL8822BE card with Intel AX200 card
Both the realtek and intel are quite fast when they're working. The realtek would be slow unless you used disabled msi, aspm, and lps within rtw_pci and rtw_core. I also tried the rtw88 driver with the same issue.
I am also using bluetooth for my mouse and keyboard, mostly without issues.
The other computers in our household have no such issues, including other Debian computers. Where can I go next to troubleshoot? Something is very consistently wrong. Here are some details from inxi and iwconfig.
