Strange random WiFi-Reconnects since Beowulf on 2 Laptops

Hello
I would need help with an issue:
I have 2 Laptops with a strange shared problem:
Every 1 to 30 minutes the wlan0 connection drops.

HW 0: Acer Aspire 5724g, i3-CPU, Ati-GPU, Qualcomm-Wifi card
HW 1: Lenovo y500, i7-CPU, Nvidia-GPU, Intel-Wifi card
(shouldn't be a driver problem with the cards)

HW 0 had Ascii and was upgraded to Beowulf  (WiFi was stable with Ascii)
HW 1 had a fresh Beowulf install
(both with XFCE, WiCD and updates installed)

Used APs: TP-Link TL-WA901N (HW-Gen 2) and AVM FRITZ!Box 7362 SL
(different BSSIDs, password, channels, distances) (and streaming devices without errors while the Laptops does reconnects)

I tried reading dmesg and logs but no hint for a problem, only these sudden attempts to connect wlan0

dmesg from the last few on HW1 (HW0 isn't here right now):

I would need your help with this issue as it prevents everything that needs a stable connection and I'm not really good with Linux yet so it would help if you could direct me (really, I don't even know what infos are needed or where to find them)

Greetings,
Lucas

Unless both cards have the same problem :-)

See https://wiki.archlinux.org/index.php/Ne … less#Intel & https://wiki.archlinux.org/index.php/Ne … ss#Atheros for some troubleshooting ideas.

Otherwise see https://wiki.archlinux.org/index.php/Ne … onnections — cause #4 looks like it might be relevant here.

tried further with my little knowledge and iwevent
seems the issue starts with

21:54:58.604083   wlan0    New Access Point/Cell address:Not-Associated

and the Atheros had less reconnects over time

I reconfigured the TP-Link massively and with many different options
mode b/g/n doesn't matter
changed the channel
disabled Qss (TP-Links WPS name)
and tried that all in 20/40 mHz and 20 mHz
(Didn't touch that AP for years cause it worked fine with Win7 and Ascii before)

And Android was streaming videos during that, except for the AP restarts, so it is possible to have a stable connection

Update:
Booted the Atheros with an older Kali and way less reconnects (but something named cfg80211 whining in dmesg about DFS Master region: unset)
I can't explain myself how Ascii could keep a stable connection with what i see now mad

Re: Strange random WiFi-Reconnects since Beowulf on 2 Laptops

you could install aircrack-ng and then run

sudo airmon-ng check

i remeber i had this problem some years ago with ubntu mate on an embedded device
i had to disable network-manager to fix this
