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. -- Regards, Alexey _______________________________________________ telepathy mailing list telepathy@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/telepathy
