I looked in ifconfig ath1, it reports 0 errors, 0 dropped packets, 0 collisions. but only the laptop above was getting booted from the network with no error even its download didnt stop, it happens very fast that interruption in service is minimal, the uptime router resets to 0:00:00 but the laptop does not disappear from the client list, thats how fast the disconnect is. This is improved, but NOT fixed.on a tl-wdr4900 v1.3 with r25045 i just made the problem happen again, it seems to only happen when theres large amounts of traffic on wifi, when i made it happen there was 5 clients connected on 2.4ghz, 2 were active, 1 being a laptop downloading at about 10mbps, & the other my iphone 6 running the app 'wifi sweetspots' its a free new app to test throughput between the device & router, it was reporting about 62mbps. ath: phy1: Could not stop RX, we could be confusing the DMA engine when we start RX up ath: phy1: Failed to stop TX DMA, queues=0x004! ath: phy0: Could not stop RX, we could be confusing the DMA engine when we start RX up
