ar71xx: “transmit queue 0 timed out" on TP-Link TL-WDR4300

Reported by: iivailo Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Barrier Breaker 14.07
Keywords: Cc: iivailo@…

Description

system type : Atheros AR9344
machine : TP-Link TL-WDR4300 http://wiki.openwrt.org/toh/tp-link/tl-wdr4300
Build: Barrier Breaker 14.07 downloaded from http://downloads.openwrt.org/ The build is from 02 Oct 2014

Every 2 or 3 days Internet stops and I can't access the internal PC in my network. I think WAN and LAN are both affected. I'm connected over WiFi. I can SSH to the router and after network restart (/etc/init.d/network restart) everything work.
