networking - My Ubuntu 16.04 keeps disconnecting from the Wi-Fi (eduroam). Why? - Ask Ubuntu


i haven't noticed pattern , i'm sure wi-fi works because have no problems same computer using windows 10. wi-fi doesn't turn off though, disconnects network , reconnects after couple of minutes.

i ran , got:

lspci -knn | grep net -a2 03:00.0 network controller [0280]: qualcomm atheros ar9462 wireless network adapter [168c:0034] (rev 01) subsystem: azurewave ar9462 wireless network adapter [1a3b:2234] kernel driver in use: ath9k kernel modules: ath9k

also running dmesg

among many messages last 1 is:

[ 3818.806656] wlp3s0: limiting tx power 5 dbm advertised 00:23:eb:39:28:21

any idea why happening?

thank you.

i suspect wireless card attempting roam instance of eduroam among several suspect nearby. confirm:

sudo iwlist scan

you can check:

dmesg | grep assoc

i think find card trying associate 1 , instance of eduroam. each have distinct mac address; a4:2b:b0:dc:45:99 , a4:2b:b0:dc:45:88 or such. if case, may have better luck if bind network manager mac address of strongest access point: ubuntu connect drops. worked while started dropping again
