Interesting... I did a "dmesg" on it and I see it keeps losing association and re-associating.
eg
[1124227.330000] wlan0: associated
[1124230.530000] wlan0: deauthenticated from c2d1e02c (Reason: 2)
[1124232.020000] wlan0: direct probe to AP c2d1e02c (try 1)
[1124232.030000] wlan0: direct probe responded
[1124232.030000] wlan0: authenticate with AP c2d1e02c (try 1)
[1124232.050000] wlan0: authenticated
"Reason 2" means "Previous authentication no longer valid" ( https://www.aboutcher.co.uk/2012/07/lin … son-codes/ ).
This is happening very often; e.g.
[1124222.500000] wlan0: associated
[1124227.330000] wlan0: associated
[1124232.070000] wlan0: associated
[1124250.500000] wlan0: associated
[1124285.150000] wlan0: associated
[1124301.330000] wlan0: associated
[1130207.100000] wlan0: associated
My other C1 only shows 3 of these messages (at bootup, at 17 days, at 28 days.. which could be when I rebooted the router).
I'm gonna reboot the dodgy C1, just in case there's something odd happening in the kernel preventing it from keeping the connection alive.
