I too find telephony over WLAN with my FB 7270 next to unusable

Can't even use 11n, in which case WLAN-connection breaks from time to time.

It seems as if power saving is a notch too high. Whenever there's no more data to stream for a (very) short while, the connection seems to back off.

Pinging the router from the N9:

Code:

64 bytes from 192.168.200.1: seq=9 ttl=64 time=195.648 ms
64 bytes from 192.168.200.1: seq=10 ttl=64 time=53.101 ms

64 bytes from 192.168.200.1: seq=18 ttl=64 time=58.685 ms
64 bytes from 192.168.200.1: seq=19 ttl=64 time=23.621 ms

Needless to say, pinging the router from my desktop has <<1ms latency. This also becomes apparent when SSHing to the mobile: keystrokes have quite a severe lag.

Unfortunately I don't know how to disable power management, to see if that indeed is the case. So I can only confirm the problem.
