While not sure how to help you it will be best if you provide us with your wifi card manufacture and model, to get that on a terminal do sudo lspci | grep Wireless and paste the output here.

My solution for my Toshiba laptop was to replace the Realtek card with an Intel card. Problem solved.

I have an HP Probook with the same wireless card and I had the same problem. Using modprobe options ant_sel=1 and fwlps=0 gave me a much better connection. If ant_sel=1 does not help, try 2 - it just depends which antenna port the antenna is plugged into on the card.

In Windows, the driver handles this automatically.

Hi, My laptop has the exactly same wireless card and I too had the same problem. It appears there is some issue with power management in the driver.

I used fwlps=0 iwlps=0 to get a stable connection.

Create a file /etc/modprobe.d/rtl8723be.conf and add the following to it:

options rtl8723be fwlps=0 iwlps=0

I did not have to, but you can try adding ant_sel=1 as tim8723 suggested
