The AirLink #AR670W does have the WMM technology.

I have a T-Mobile UMA enabled blackberry, and think there may be another explanation for the battery life issue. Normally I can get 3-4 days of standby time on my blackberry while in UMA mode at home. Occaisionally (like once a month), I will notice the battery drain in 1/2 of a day. When this happens, I notice that the phone is switching back and forth between UMA mode and EDGE mode every few minutes. The up and down arrows indicating that the radio is active are on constantly until the battery runs out.

I don’t know exactly why this happens but would speculate that my home Internet connection is degrading enough to cause the Blackberry to pop out of UMA mode and then just getting good enough to switch from EDGE mode back to UMA.

If your router supports it you can always flash to the DD-WRT firmware. Has WMM capability built in. http://www.dd-wrt.com

The Linksys WRT54G v4 does support WMM. They have it stuffed under QoS which is under “Applications and Gaming”

Now, if I could only get the Bold here in the states.

The Linksys WRT54G-TM router that T-Mobile gave me with my Curve has WMM. I guess I’m already getting the battery boost… who knew?

I was hoping to put the idea out there to see if we could get some more concrete information. 15-40% longer battery life is no small feat…

The Linksys WRTU54G-TM router supplied by T-Mo for HotSpot@Home AND TalkForever Home Service does not seem to be on the list provided, while the D-Link DIR-655 I used to run before I got the T-Mo router is. Damn!!

Since T-Mo is the big UMA BlackBerry provider in the US, any word on if the T-Mo routers have this one by default as well? Rogers, Fido, and Orange I think also offer UMA. Sprint has a similar thing too. We need the details here people!!

I was pleased to find that not only did my DIR-625 D-Link router have WMM, it is also enabled by default!
