The "HTC Desire", "HTC Droid Incredible" and "HTC Aria" need some extra setup-steps to make "Wireless Tether for Root Users" work.
(First you need to root your device. Please use google-search to find a guide/tutorial).
--------------------------------------------------------------------------------
1) Download a HTC Evo 4g system-dump (use google search - I bet you will find one)
2) Extract a file named fw_bcm4329_ap.bin (located in /system/etc/firmware)
3) Mount your sdcard
4) Create a directory named "android.tether" (without quotes)
5) Open this directory and copy/move fw_bcm4329_ap.bin into it.
6) Rename fw_bcm4329_ap.bin to fw_bcm4329.bin
7) Install the latest versions of "wireless tether"
If you read the Setup HowTo on the Android Wi-Fi Teather page it explains what you need to do to get it to work.

This is the one I used and it works great. Not sure if it's the same one you are looking at or not.
Hope this helps
Did you at top?
(These extra setup-steps are not required if you have Android 2.2 (FroYo) installed.) A rooted handset is mandatory

I just went through this process. I have an Incredible, root with unrevoked forever. Download the apk from the link above and it should work great.
does the "##778 DUN" method work on a Root user phone?

I just rooted my friends phone and use wifi tether. It showed a N network but I couldn't connect to it. Now I'm reading it requires a custom kernel? Is that correct?
IS this the same for SETCPU as well?
