Title: Wireless N problem solved - DIR-655, Intel 5100 Adapter
Post by: mco on January 29, 2010, 06:33:56 PM

In case others have the same problem as I did (i.e., PC wouldn't connect at more than 54Mbps/wireless-G speeds) and want to avoid hours of frustration and deadends...  To summarize what I did to get this to work

1.  Have current Intel driver (on their website); Lenovo had not installed current driver on my new laptop; oh well
2.  Set router to 20/40 Auto channel width, mixed n/g
3.  Turn on WPA2/AES encryption
4.  Enable WMM and QoS on router (QoS was already on for me, but people on Intel forum told me to check it was on so sure it must do something good)

Step 4 worked magic - went from 54Mbps to 270Mbps in a hurry.  Speed fluctuates a bit it seems but still a vast improvement.

Thanks to you who tried to help.

If you disable WMM you won't get n speed obviously, because WMM is a wireless n required feature.

Don't think so.

I got the inverse problem: I didn't use QoS in my DIR-655 and if I enable WMM, my speed drop from 300Mbps to 54Mbps on my Broadcom 4322 n wifi card (Dell 1510). I'm running 1.33NA firmware but having the same issue with the 1.32NA.

So don't take the "proof" mentionned above as a universal truth. There is a fact: in case of problem, do your own test to point the real problem. Good luck!  :)

Wireless n is a standard, so you have something wrong on your side, either a misconfiguration or wrong implementation of your hardware manufacturer. But yes, it's best to test to know the truth as the truth is sometimes different from fact and vice versa :D, also the truth can be different from person to person.
