Description

I'm using TP-LINK wr841n & Openwrt r35400. I have configure this router as client to another TP-LINK wr541g with stock firmware, but the connection is not stable and every time "ath: phy0: Failed to stop TX DMA, queues=0x005" appears in kernel log, it's likely reassociate with ap and cause connection drop.
