So it stays working with -dd, but I do get *occasional* failures that then seem to clear up on retry. So it ends up working in the end, but I think I have a few example failures in the logs. So for example, from my dmesg, I get this: [14:07:15] wlp1s0: authenticate with 20:9f:db:e7:80:80 [14:07:15] wlp1s0: send auth to 20:9f:db:e7:80:80 (try 1/3) [14:07:15] wlp1s0: send auth to 20:9f:db:e7:80:80 (try 2/3) [14:07:15] wlp1s0: send auth to 20:9f:db:e7:80:80 (try 3/3) [14:07:15] wlp1s0: authentication with 20:9f:db:e7:80:80 timed out [14:07:18] wlp1s0: authenticate with 20:9f:db:e7:80:80 [14:07:18] wlp1s0: send auth to 20:9f:db:e7:80:80 (try 1/3) [14:07:18] wlp1s0: authenticated [14:07:18] wlp1s0: associate with 20:9f:db:e7:80:80 (try 1/3) [14:07:18] wlp1s0: RX AssocResp from 20:9f:db:e7:80:80 (capab=0x431 status=0 aid=16) [14:07:18] wlp1s0: associated [14:07:22] wlp1s0: deauthenticated from 20:9f:db:e7:80:80 (Reason: 2=PREV_AUTH_NOT_VALID) with another failure at 14:07:22, but then it ends up working a bit later at 14:07:33. I've got the wpa supplicant log for this timeframe, but I'd rather not send it out in public. I see "[REMOVED] for what looks like the key data, but there's a lot of other hex data. Is any of it sensitive? Linus
