Sorry if this is dumb, I'm new to Ubuntu and just jumped in. My issue is the my WiFi will connect fine, but after a few minutes it will stop working, but still say it's connected fine. I can temporarily fix this by disconnecting and reconnecting, but it will occur again. I'm not sure if I need some sort of driver or software, so if anyone can answer or anything it's greatly appreciated.

  • Please [edit] your question and add output of lspci -knn | grep Net -A3 terminal command. This will give the information needed about your specific WiFi device. Also make sure to set the recommended wireless encryption settings, WPA2-AES, at your router. Avoid any WPA/WPA2 mixed mode and/or TKIP. –  Nov 05 '17 at 20:18

  • Possible duplicate of Wireless disconnect issues Ubuntu 16.04 with RTL8821ae Yes, your device need tweaks, the default driver installed by Ubuntu isn't the best. –  Nov 05 '17 at 20:56
  • @MichaelBay I don't see a valid answer for that question – Jeremy31 Nov 05 '17 at 22:15
  • @Jeremy31 Isn't it the same device, same Ubuntu release and same problem? Shouldn't at least the ant_sel work? From all that I've read regarding this chipset that seems to be the main issue. –  Nov 05 '17 at 22:18
  • @MichaelBay the one answer was downvoted and the other one didn't work for the asker. It is the same device – Jeremy31 Nov 05 '17 at 23:05
  • @Jeremy31 Ok, flag retracted but regardless of that particular case - and my choice of dupe was unfortunate indeed - when I looked at the upvoted answer it made sense and was consisted why what I've been reading about this chipset with Ubuntu, specifically the issue with the single antenna certain manufacturers ship it with that is correctly detected by the Windows driver but not with the Linux driver. –  Nov 05 '17 at 23:23

    @MichaelBay the single antenna issue seems to be limited to HP laptops with RTL8723be chipsets – Jeremy31 Nov 05 '17 at 23:32
  • @MichaelBay I think that post may have helped me figure out my issue, so thank you very much – A Quest Nov 06 '17 at 00:28
