Wifi N standartui tai priklauso pagal spec'us. Jei neįjungsi WMM, gali 
net gauti sulėtėjimą iki 54 Mbps. Nors ne visi routeriai taip daro, bet 
būna ir taip. Jei nepatinka, QoS kompe gali išjungt, bet routeryje WMM 
palik. Arba, pasibandyk praktiškai. Kai kurie routeriai, išjungus WMM, 
wireless N režime greičio nenumeta, netgi priešingai, rodo maksimalų 
pralaidumą testuose 10-20 proc. didesnį, bet tai testai, realiai 
naudojant visokius p2p, voip ir video stream vienu metu, WMM gali labai 
pasiteisinti.

Basically, the 802.11n spec requires devices to support 802.11e (Quality 
of Service [QoS] enhancements for wireless LAN) in order to use HT (High 
Throughput) link rates, i.e. higher than 54 Mbps. (WMM is a subset of 
802.11e that was created by the Wi-Fi Alliance as a stop-gap measure 
while 802.11e made its way slowly through the IEEE review process.) 
WMM's Traffic Identifier (TID) field is key to aggregation mechanisms, 
including block acknowledgement (block ACK), that enable 802.11n's high 
throughput rates.

Since WMM support is required for products to be certified for 802.11n, 
WMM comes enabled by default in all Wi-Fi Certified n APs and wireless 
routers. So even if you don't have any WMM-aware devices on your 
network, leave WMM enabled or you may find your clients connecting only 
at 54 Mbps rates.
