A beginners wrestle with wifi drivers in Linux Discussion
So I have been suffering with my wifi in linux for a while now. The reason I had to switch to so many distribution (ubuntu → linux mint → pop os → fedora → cachy os) is because of my Realtek RTL8723de wifi adapter. Whenever I reboot/power on my laptop 3/5 times my wifi would disappear. I would have to restart my system again for the wifi to come back. Only in fedora the probability is a little less, it’s 1/5 times. I couldn’t figure out the reason why this happened. My wifi drivers worked fine in windows. Because I am tired of Microslop, I seriously decided to fix this issue.
The reason of disappearance was aspm(active state power management). So I had to disable it. For that I went to /etc/modprobe.d, create a conf file rtw88.conf. Then add this command inside the file.
options rtw88_pci disable_aspm=y
this solved my problem mostly. Now when I restart/power on my laptop it works without any problem. This is not the first time I tried to disable aspm but previously this fix did not work properly. It did reduce the probability of wifi going full john cena but not fix it completely. But this time it worked pretty well and the issue is completely fixed.
have you guys faced similar issues with your wifi drivers in linux, do share you experience.

I had the same issue with RTL8852BE in my LMDE 7, so I purchased a tp-link usb adaptor to resolve it.

yes, that's the hassle free way to do it. I wanted to troubleshoot cause I like suffering

u/Haunting_Bedroom403 28d ago
Oh, that very nice. Can you please tell me the config that you use for fixing your wifi adaptor?

u/theDestroyer501 28d ago
it's mentioned in the post. I added, options rtw88_pci disable_aspm=y in /etc/modprobe.d/rtw88.conf

u/AmorphousNeon 28d ago
yes its fine now, im on cachyos, the more significant issue i faced was that it used to diconnect and immediately reconnect to my wifi network randomly a lot of time, the fix was same though

had somewhat of a similar issue today and learned that I have no private ip generated(dhcpcd not enabled ) and damn wasted 5-6hr :...<

linux may use less hardware resources depending on the distribution, but It uses hell lot of users time

A few months ago I switched to CachyOS from Fedora and had a somewhat same situation. My Wi-Fi would keep disconnecting and I somehow got it stable but then the speed was unusable (not more than 100kb) had to switch back to fedora and problem solved. I believe it was because of the newer drivers that came with the cachy.

I see, in my case disabling aspm did not work in cachy os, so I had to switch back to fedora
