Hi, I am trying to figure out what happened to my wifi signal. The signal was fine on my laptop up until a few days ago and now I am back to dial-up speeds (0.1 Mbps). My work laptop (runs on Windows) is getting normal speeds (~30 Mbps download/5 Mbps upload). I was googling for a solution but am not a developer so I wasn’t 100% sure that the solutions were right for me. Here is the info on my computer:
Ubuntu 18.04.3 LTS with a RTL810xE PCI Express Fast Ethernet controller. I include this info because people on the other internet forums were talking about how it is a problem with the Realtek driver, but I don’t want to go off half-cocked and start putting on a new driver (the lwfinger/rtlwifi_new driver on github was suggested) because I don’t know if that is the correct driver to use (and my computer is too slow to download the file).
I tried to switch my antenna using this (from https://ubuntuforums.org/showthread.php?t=2394845) but wasn’t sure if I was doing it right (like, do I type in the " or is that just bracketing the command in the line of text?):
echo “options rtl8723be ant_sel=2” > /etc/modprobe.d/rtl8723be.conf
It says that all of my software is up to date. Is there something else that I can check/fix/install? Thanks!
