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.
