Windows 10 disconnects Wi-Fi randomly, Ubuntu on same laptop doesn't
Hi community,
I am facing a pretty silly bugs with my wi-fi connection on Windows 10.
Basically, Windows just disconnects from my home wi-fi (just a few devices) randomly, sometimes every minutes, sometimes 15 minutes. Sometimes, it re-connects automatically, sometimes I have to do it manually. When it happens, I am just surfing social network. I feel like when the connection is lost, the Wi-Fi menu is laggy.
The video can illustrate the problem (at around 0:05, 1:05, 2:16) Wi-Fi connection isn't stable - YouTube
My system information:
Dell XPS 9570, latest BIOS and drivers (checked by SupportAssist from Dell), Windows 10 21H1, build 19043.1165 (Windows Feature Experience Pack 120.2212.3530.0)
The Wi-Fi analyzer from Killer Control Center. (mine is "Wifi Nguyet Minh")
---------
What I have tried:
1. Running dism /online /cleanup-image /restorehealth
2. Resetting network by going to Network and Sharing settings > Status > Network reset
3. Uninstalling network driver (intel Killer 1535) and re-installing with Dell version. Actually, windows automatically re-installs exact driver version from Dell (12.0.0.1118)
4. I have Ubuntu dualboot and the network works like a charm.
5. Trying with another Wi-Fi in my house (weaker signal), problem still happens.
6. Resetting my modem (and I have to setup my WAN connection again), choosing static channel (channel 1), 20MHz bandwidth
Hope to hear your solution or something to trace back the cause other than re-installing my Windows. Thank you.
