Hi!

I see the bad ping of my device from the same wireless network like this:
ping 62.205.xxx.xxx
PING 62.205.xxx.xxx (62.205.xxx.xxx) 56(84) bytes of data.

--- 62.205.xxx.xxx ping statistics ---

rtt min/avg/max/mdev = 19.443/128.911/257.718/69.734 ms

It leads to slow data transfers and awful ssh performance.

If I do "iwconfig wlan0 power off" to disable power savings - ping normalizes to 1-2ms, but after some time someone switch it back.

How it can be fixed completely?

Maybe you are wearing wrong colored socks in you feet or you need to change your AP :-)

Checked serveal [s]socks[/s]APs, n ang g - same result...
