And every now and then the router crashes and reboots (I have not yet found a way to make this happen reliably, it seems to require some uptime) This looks to me like a possible memory leak somewhere, but I'm no expert. (Unless cerowrt is using tmpfs and filling up memory with logs, of course.) Is UDP from the wired side to the Internet also OK? I'm assuming it is, but it would be nice to prove that it is actually a leak in ath9k and/or the wireless stack first!
