Wifi stops working after few seconds

Support Network
1

I bought the card: TP LINK TL-WN781ND Ver:3.20 Wifi card to give an upgrade to my old desktop computer.
But the problem I am facing is that the WiFi stops working after few seconds after booting. I had the same problem in ubuntu. But the card works fine in Windows 10.

The card uses RTL8188ee driver.

my kernel version is 5.6.19 and I am running Manjaro-20

Sometimes (rarely) for some reasons the WiFi card starts to work without any problem. I was able to recreate this situation by restarting my computer LOT of times (when I was still using ubuntu). Haven’t tried it on Manjaro yet.

I also tried resetting the BIOS and reinserting the CMOS battery after reading about it in a post in this forum, it didn’t work.

I have tried kernel 4.19, 4.14, 5.8, 5.7 none of them fixed the problem.

How can I fix it?

For some reasons the output is linked to your LAN and not to your WLAN, please enter

sudo lspci -v

and only copy the paragraph linked to your Realtek RTL8188EE Wireless Network Adapter.

OK, let’s start trying to switch off aspm by

echo 'options rtl8188ee aspm=0' | sudo tee /etc/modprobe.d/rtl8188ee.conf

Afterwards run

sudo modprobe rtl8188ee

Maybe you need to reboot afterwards.

In addition check output of

rfkill list

A further option I see if this does not solve your issue is to replace the Network manager, here is an excellent tutorial (from famous @tbg in the old forum):

did not fix the problem

11

is connman better than the default network manager?

12

The standard Network manager is known to make problems for some hardware/drivers, it’s worth to try it.

13

ConnMan didn’t work either :frowning:

14

Then let’s hope that some more experienced forum members join this thread. :man_shrugging:

15

I think its a driver issue. Is there any way to get the attention of the developers on this issue? Where can I report these problems directly to the developers?

16

SOURCE: Realtek RTL8188EE wireless stopped working reliably - Linux Mint Forums
Follow and create config magic file:

echo "options rtl8188ee swenc=Y ips=N" | sudo tee /etc/modprobe.d/rtl8188ee.conf

Reboot.

This is common issue with this sh*tty chipsets.

Seems to be UPSTREAM kernel driver issue. Reported here >> https://bugzilla.kernel.org/show_bug.cgi?id=206513

Repo in lastest post is dead. But lwfinger / Repositories · GitHub

19

I have tried that repo. Someone else has uploaded it in github. But installing the new driver didn’t fix the problem and the make command doesn’t run without error in kernel >5 so I tried kernel 4.14 to compile the driver. But the problem didn’t get solved.

Please help. :sob:
