Hi all,
I recently bought an R6400 and installed Tomato-by-Shibby ( version 1.28.0000 -137 K26ARM USB AIO-128K ).
To my surprise, my wife's laptop (thinkpad t430, ubuntu 14.04) intermittently loses connection and cannot reconnect to the router. Once this happens, the problem persists even if I move the laptop close to the router .
( One of these times, my laptop (thinkpad w530, ubuntu 14.04 ) also could not connect. Overall the problem has been confined to the T430 )
When the laptop cannot connect, this message appears in the dmesg output:
[315402.592819] wlan2: direct probe to 10:3c:35:7d:a6:08 (try 1/3)
[315402.796942] wlan2: direct probe to 10:3c:35:7d:a6:08 (try 2/3)

[315410.214960] wlan2: authentication with 10:3c:35:7d:a6:08 timed out
Note that this problem only occurs on the 2.4Ghz band; her laptop cannot connect on the 5Ghz band.
Workaround: Reboot
The solution: reboot the router. Once I reboot it, my wife's laptop can connect fine...for about 24 hours.
No Sign of Problem On the Router Itself
When this problem occurs, I did not see any problem on the router itself, (I see no obvious issues in the router's dmesg output)
Questions
- How do I go about confirming whether the problem lies in the laptop or the router?
- Would upgrading the firmware help? ( I see tomato 138 has been released)
- Could distance affect these timeouts? Our router is in the basement. I get '3 out of 5 ' for signal strength. We never had problems with the old-and-cheap wifi-router before, so I presupposed the 'stronger router with better firmware' would run without problem.
- Could traffic affect the timeouts? We put our wireless phone base near the router. Both use the same frequency
thanks in advance
did you clear nvram in router after flashing ?
