[SOLVED] WiFi signal way to weak on my HP laptop

Post by mazerunner » Sun Dec 03, 2017 5:03 pm

New user to Linux Mint.

After installing Linux Mint 18.3 "Sylvia" - Cinnamon (64-bit) on my HP laptop, I realize that the WiFi signal is way to weak (40% to 50%)

The rooter is here in the same room, 3 m. away, and there is even visual contact with the rooter's antenna. All other devices, like android tablets and cellphones, seem to get a full signal.

Any ideas as to what can be wrong?

Thanks :)

Well, I solved my problem, with some help elsewhere. Just for the record, the network card of this HP model seems to have just one antenna (instead of two). So, the driver had it wrong, what antenna is connected and where.

Solution: with the driver already installed try:

sudo modprobe -r rtl8723be
sudo modprobe -v rtl8723be ant_sel=1


and
sudo modprobe -r rtl8723be
sudo modprobe -v rtl8723be ant_sel=2


and see which of the two will get you a strong wifi signal.

Then edit the option in /etc/modprobe.d/rtl8723be.conf with a command like this one:
echo "options rtl8723be ant_sel=1" | sudo tee /etc/modprobe.d/rtl8723be.conf
