weak wifi on new install

[MANTI5]

I installed Linuxmint yesterday on my elderly father inlaw's HP laptop because I was tired of all the viruses he was getting from not understanding what not to click/download. Everything is working great except the wifi strength, it wasn't an issue in Windows but now it needs to be pretty close to the router to get a signal. I'm very green when it comes to *nix so any help with a setting or something I missed will be greatly appreciated.

See if

Code: Select all

sudo modprobe -r rtl8723be && sleep 10 && sudo modprobe rtl8723be ant_sel=2

Helps, if it does, you can make it persistent with

Code: Select all

echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723beant.conf

Thank you that seems to have helped.
