Since recent updates I have experienced problems with WLAN. It stays now on only a few minutes. After vanishing, I cannot see any WLAN networks, if I try to set it up again. Any idea what could have caused this behaviour?
WLAN is up and running only a few minutes so I can hardly type this before it goes down. I cannot get any updates either, because that takes more time to get active…
I can help with the HW identification, if I get some help…
wlp4s1: Limiting TX power to 20 (20 - 0) dBm as advertised by 24:7f:20:9f:a9:35
may underpowering issue may you can disable power handling for it…

As of Linux 3.15.1, some users have been experiencing a decrease in bandwidth. In some cases this can fixed by editing /etc/modprobe.d/ath9k.conf and adding the line:
options ath9k nohwcrypt=1
Note: Check with the command lsmod what module(-name) is in use and change it if named otherwise (e.g. ath9k_htc).
In the unlikely event that you have stability issues that trouble you, you could try using the backports-patched package.
Thanks a lot @joekamprad !
I cannot practically use anything else than WLAN for this desktop. Now I feel somehow crippled when the network disappears.
I installed this system using the same WLAN and I remember that it caused some issues in the installation process. After configuring the WLAN card for use, it has performed splendidly until recently. I suppose this WLAN issue has been active now for about three weeks.
I’ll check that procedure in the evening.
PS. for some reason, I am not getting any emails from Antergos Forum anymore… ?!
I haven’t noticed there was any spam protection. Need to check if there is such a folder anyway…
Oh yes, you guessed it! There they were. It was called Junk Email. Now I need to find a way to say they are not junk for me.
Well, anyway I had not seen any emails there until today. I had stopped checking it, because there wasn’t anything ever. Now, if I these messages from Antergos always go there I won’t get alerted… :(
Ok, I had to create the mentioned ath9k.conf file. Now the file is there and contains only that one options line. So far, the WLAN connection is up and running. But I need to wait some more minutes…
Thanks for the tips!
Maybe I can try that command for checking the HW and see if there are still those errors…
WLAN worked the whole evening the other day when modprobe file was created.
But yesterday this PC started without WLAN and later on after restart it was again just some 10 minutes on and then disappeared.
What else could be wrong?
Thanks for all the help anyway!
after the updates started working, also WLAN has managed to stay up and running. I think I can close this issue.
Thanks for the help!
