I've a Lenovo flex 6-14, dualboot Windows and Ubuntu 23.04. After a month of no problems, suddenly wifi problems started. The wifi stops working after i open e.g a youtube video. Then the wifi button dissapears. The way i fix it is to restart.
To make sure it's not a hardware issue, i used Windows for a week, without any wifi problems.
The output of lspci -knn | grep Net -A2 is:
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter [10ec:b822]
Subsystem: Lenovo ThinkPad E595 [17aa:b023]
Kernel driver in use: rtw_8822be
I installed rtl8812au-dkms as suggested here, but rtw_8822be is still in use. Not sure if i should mess with this in the first place.
Any ideas?
