wireless dies: "kernel: NETDEV WATCHDOG: wifi0: transmit timed out"
|Reported by:||openwrt@…||Owned by:||developers|
I have openwrt on a fonera, with the network set up as follows:
internet <<wireless eap-ttls/pap>> (ath1)[fonera](eth0) <<wired switched lan>> [pc's]
When uploading, for example when using bittorrent, the wireless network will stop working after some time. It usually takes a few hours or so for this to happen, which translates to several GB of uploaded data traffic - unfortunately that makes this bug a very regular occurrence here. I do not know of any quicker way to trigger this bug.
The following message appears in the logs (repeatedly) when "shit happens":
user.info kernel: NETDEV WATCHDOG: wifi0: transmit timed out
After the first such message, the wireless stops working completely; even restarting the network doesn't bring it back to life, only a reboot does. Everything else, including the wired network, keeps working fine. No other errors are logged, nor any type of oops or crash.
