I installed elementary OS 7 on my laptop 2 days ago. In the beginning everything was working well, but today my Wifi simply stopped working. I can see no available connections in the network list and although I'm able to connect to the internet through a wired connection, I cannot create a hotspot on my computer. I'm not shown any error when I turn the hotspot on, but it doesn't show up as an available connection to other devices in the vicinity. Running
dmesg shows the following error messages which I believe are related:
[ 107.750470] rtw_8822be 0000:07:00.0: failed to read ASPM, ret=-5 [ 109.749418] rtw_8822be 0000:07:00.0: failed to poll offset=0x5 mask=0x2 value=0x0 [ 109.749434] rtw_8822be 0000:07:00.0: mac power on failed [ 109.749436] rtw_8822be 0000:07:00.0: failed to power on mac [ 109.749438] rtw_8822be 0000:07:00.0: leave idle state failed [ 109.749624] rtw_8822be 0000:07:00.0: failed to leave ips state
lspci reveals this to be my wifi card:
Network controller: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter
Any help on solving this issue is much appreciated. Thanks in advance.
Update: After following Vlad's suggestions, some of the error messages disappeared, namely the ones related to ASPM, but I see the following new ones now:
[ 6.568678] rtw_8822be 0000:07:00.0: Unable to change power state from D3cold to D0, device inaccessible [ 6.575083] rtw_8822be 0000:07:00.0: failed to setup chip efuse info [ 6.575114] rtw_8822be 0000:07:00.0: failed to setup chip information
