My download speed with Blast and a Motorola 6121 wireless router jumped from 16 Mbps to 36. Using my iphone my wireless download speed jumped from .6Mbps to 16!! Funny thing is--5 techs and 3 supervisors at Comcast didn't tell me this. I found it posted here in the forums.

More techs and comcast csr's should read these posts . I don't know how many times i have heard but comcast will not let us go to "that" site . It should be part of there training answering questions on forums site also the store csr's as part of there "down" time .

Also keep in mind disableing WMM shuts down the N portion of your router so you will only have G and A working no wireless N. Not a problem if all your devices are still useing G.

It's certainly worth trying since it takes a few minutes and saves you hours on the phone getting nowhere with comcast reps. I literally doubled my download speed with my wireless router and my iphone over wifi jumped from .6Mbps to 16 Mbps download. No one at comcast suggested this and I spent a week on the phone with them-speaking to 6 reps, 3 supervisors and the tech who came out to my house to try to fix it-he didn't.

Kev--I am using a Motorola 6121 modem with a Netgear RangeMax Next Wireless Router (WNR834. Both my modem and router are different from the author of the blog and I am seeing the exact same result in dramatically increased download speeds. It took me literally 30 seconds to turn the WMM settings off so it's worth a try. I am still getting an N connection and download speeds on my Macbook Pro running 10.6.8 of 36 Mbps and 16 Mbps on my iPhone 4 over Wifi using the Blast service.

Dont shoot the messenger this comes right from Cisco because i called them about this issue. They said radio type N can only work with WMM enabled. They also said you can get better speeds useing G when your devices dont have N but if you have a N recieveing device WMM must be enabled. I tried what you all are doing on my router never had the download issue you all are having but nothing changed for me enabled or disabled. But when it was disabled when i put my mouse over my ssid it said G when i enabled it it showed N again thats what prompted my call to Cisco. If it workes for you great enjoy the added speed. If it were me I would buy another router or maybe a firmware fix will take care of it.

@ Jim721. I tried this on a Netgear WNR1000 that I have laying around and the same thing happens. Disabling WMM results in it dropping out of "N" mode and going in to "G" mode.

On my Netgear router disabling WMM still keeps me connected at an N, not G. Bottom lne is no solution will work for everyone in every case but this does seem to be quite an extraordiary and simple fix for alot of people.

I agree with you it's so simple that it makes me wonder why these router builders and testers dont see this issue. Nobody wants to buy a new router and have there speeds go down it dont make sense. Maybe if more people tell them whats going on they will offer a fix. Good Luck !!! PS: How are testing to make sure its still N ?

Totally agree--I was shopping for a new router when I read this approach in the forums and couldn't believe the speed diffference. My girfriend has a iPhone 3G she was about to smash against the wall because of the slow speeds over wifi andf it's also screaming at 16 Mbps now instead of the .5Mbps she was getting before. I don't why it works but I'm happy it does and hope others find it and it works for them as well.
