I installed Ubuntu 18.04 on laptop Kiano SlimNote 15.6 HDD with Intel N3350 CPU and everything works properly except wireless and bluetooth. Her is listing of relevant commands:

The level shows only 40% and it should be close to 100%. Few meters from the router and the connection drops off.Code:t@t-K:~$ uname -r 4.15.0-24-generic t@t-K:~$
Wit the BT it seems to be working but does not discover any bt devices even on very close range.
All my other laptops and smartphones work fine with this router.
I tried everything I could on my own but to no avail. Please help.
