Comment (by alexander.wetzel@…):

 Now this is getting stranger all the time:

 To verify that the issue is the Openwrt router I connected another Win7
 notebook with EAP-TLS to the network. (Again using the 5min rekey
 interval.)

 '''And that one stays operational!

 At the rekey time it only loses one or two pings. (I would have expected
 the rekey to be seamless, but then that could well be normal...)
 So this seems to indicate that this may be not the fault of the router but
 the client.

 That's hard to accept, since it would indicate that EAP-TLS rekey is
 broken in some generic way on the clients, affecting at least two
 different distributions and wlan drivers. (Maybe something in nl80211 or
 mac80211?)
 But that would affect (nearly?) all wlan cards and at least many EAP-TLS
 users would have the same problem.

 Guess I should try to find another EAP-TLS AP I can connect to which is
 not running openwrt to verify that.
 That will be hard, though...
