Today I tried a different wifi card on the client side, instead of the Intel 5100, but the problem remains the same. The carl9170 driver on my server crashes at some point randomly (only in 802.11n mode). The traceback shows the error at tx.c but everytime in a different line. So I guess there must be a race condition somewhere. Here you can find the error report of some crashes: http://www.mikrocontroller.net/attachment/95144/bugreport.txt Server hardware is a Seagate Dockstar with OpenWrt running on it. I heard from another user with Debian, who has the same problem.
