Hmm, i'm confused.
if i understand correctly, the behavior like: 2 packets send / 2 packets
receive can be caused by firewall.

WMM is completely  different. WMM make sense only on the air, between AP
and client. If AP was configured correctly (my dd-wrt seems not
configured at all), it will map DSCP numbers to WMM (0x18->BE; 0x10->
BG; 0x28->VI; 0x38-> VO). Empathy do not set DSCP, Skype do not do it
too. It seems like some/all ISP ignore DSCP or reset it to 0. So WMM or
DSCP do not make any difference.

So i do not understand how this two thing connected.
