I've had this issue before but after all the options I've found online I'm still no further forward this time.

I've got a HP Laptop with the rtl8723be wifi adapter. I've had issues in the passed with this driver and recently got it working with lwfinger's rtlwifi_new driver and guides. However, after updating my system yesterday I noticed that after a reboot the WiFi had gone again. I went through the guide again and have got it working but now the signal is sitting at 1 bar even though I'm right next to the router.

I've tried adding the file /etc/modprobe.d/rtl8723be.conf with options rtl8723be ant_sel=1 and with ant_sel=2 or ant_sel=0. Still don't have a better signal. I know this works fine in Windows, but for university I'd much rather stick with a linux OS instead of going back to Windows.

I noticed that doing this worked till I restart then it wouldn't work on 2nd attempt.

sudo modprobe -r rtl8723be 
sudo modprobe rtl8723be ant_sel=2

Any advice would be great. Cheers.

It seems kernel v4.15.0-33 (and probably -34 too) has a bug, see this too: https://askubuntu.com/questions/1069153/wifi-networks-not-found-ubuntu-18-04-with-rtl8723be – pomsky Sep 13 '18 at 14:36
  • Hi. I've tried the solution from that question. The driver from lwfinger didn't seem to fix this issue either. – Woddell Sep 14 '18 at 06:23
  • Try switching to an older kernel if possible. – pomsky Sep 14 '18 at 06:24
