Recently, my kernel was upgraded to 5.11.x but everything but one thing worked fine. I lost wireless connectivity to the internet. Unless I am really close to the router or I am connected to the internet via a LAN cable, I am unable to connect to my AP.
I have RTL8723BE wireless adaptor and I see that the drivers for this is already installed in the kernel but nonetheless it doesn't work.
I have tried to change the ant_sel option to 0, 1, and 2 but none of it works for me. I have also tried to compile the drivers from rtlwifi_new git repo (which is removed from GitHub now) using the local source code copy but that also fails in the make [first] step.
At this point, I want to be able to downgrade to 4.9.x lts kernel so that my Wi-Fi starts working again.
Can someone please provide me a set of commands that would help me achieve that? Thank you for your time and efforts.
I have the same issue as @jrsilvey mentioned in one of his comments:
I have an older Dell Inspirion and I have run Solus on it with no problems (or reinstalls) since March of 2019. It uses the linux-current kernel with absolutely no issues at all.
I have an HP Laptop (with an Intel processor) that I used to have as my main rig. However sometime last December or January the wireless capabilities just.. stopped. The Ethernet port doesn't work and so I lost all internet connection completely. I formatted the harddrive and installed Manjaro on my HP and the wireless adapter worked for a few days and then it stopped working again.
I wasn't able to use it for about three months until I figured out there was an common issue with the kernel and ethernet between 5.4 and 5.6. As of last night, my HP laptop STILL won't work unless I am running 4.19 on Manjaro. I reinstalled Solus last night to see if anything changed and had issues connecting to WiFi on linux-current until I switched to the linux-lts kernel. Once I did everything worked fine again.
I am certain that the issue is kernel based and has nothing to do with the distrobution. However if you use any kernel above 4.19 I fear that I won't be able to use my wireless adapter to connect to the internet and I'll be in the same boat I was before.
I am cool with whatever choice you make on this matter (as long as my Dell laptop can still connect to the internet using Solus) but I thought the issues I had with my wireless adapter and the LTS Kernel would be relevant to this conversation. Not everyone has the ability to switch out laptops if something unexpected happens and I'd hate to see this issue adversely affect Solus users who might not have an easy way to fix it.
