I have a HP 14-AN001NA laptop. It came with Windows 10 installed on which the wifi worked fine anywhere in the house. However I removed windows 10 and installed Ubuntu 16.04 instead and since I have had terrible wifi anywhere aside from about three foot away from the router. I don't know if it's relevant but my wifi is not called wlan0 but wlo1 for some reason (I didn't change it).
When running lspci -knn | grep Net -A3 I get the following output:

Run in a terminal
sudo tee /etc/modprobe.d/rtl8723be.conf <<< "options rtl8723be ant_sel=1"
and reboot.
The ant_sel parameter enables one of the two antenna connectors of your RTL8723be adapter. Your laptop has only one antenna because the vendor is too greedy to install two. The Linux drivers can't detect which antenna connector is in use. So we have to guess it.
In Windows either the vendor sets it up somewhere on a pre-installed system, or the Windows proprietary drivers can detect it.
If ant_sel=1 does not help, use ant_sel=2. This setting tells which antenna is in use 1 or 2.

Works great! But it disconnects randomly. Would you be able to help on how to fix this? I am using Ubuntu 16.04 LTS
