Hello!

I have probably a common, yet frustrating problem. I'm using my laptop (HP 250 G2) and as I said in title, in last 2 weeks my laptop started to lose connection after few seconds. I have two wi-fi networks in the house: 1 on upper floor and 2nd one in basement and first floor. I mainly use the one on upper floor - the problematic one.
All my other devices (playstation, mobile, tv) works fine with this wi-fi, while laptop doesn't. I've restarted router and laptop several times, I've done power cycle, refreshed DNS service, used ipconfig in cmd, reset router and modem etc. Basically everything I know. And I still don't have connection most of time.
Sometimes laptop detects wi-fi, and doesn't connect to it at all, or (in worst case) it is connected but in browser (Chrome) I get "This site cannot be reached" and other DNS errors.
Is there any other way to get connection stable?

Thank you for help.

Regards
