If I ping my router from N810, I see fairly substantial delays:

/home/user # ping 192.168.0.1

I am literally 10 feet away from the router. Occasionally, there is also packet loss.

ifconfig reports some TX errors:

wlan0 Link encap:Ethernet HWaddr xx:xx:xx:xx
inet addr:192.168.0.80 Bcast:192.168.0.255 Mask:255.255.255.0

For comparison, my Ubuntu laptop has a consistent ping time of 1.2 ms.

Things are even worse when pinging N810 from another device on the local network.

This is pretty bad. I wonder if the problem is specific to my device, or if all N810's are affected. If anyone has root access, can you please ping your router a few times and post the results in this thread?

Thanks!
