I just rooted, and I'm unable to to do a wireless tether?

[Player707]

Hey everyone, I've been meaning to root my phone and I finally did it today, I'm not very technical savvy but it was really easy! So I went with the Eclipse ROM with looks 100x better, wow so amazing, but I tried to android-wifi-tether, but as soon as I opened the application, I get the error message "Sorry but your kernal does not have all necessary features for the Access control feature of this application...." and it goes on for a little while longer. I'm really sorry to ask, but where I can download the necessary kernal to enable the wireless tethering?

EDIT-----

Also I'm unable to see server when I try looking for WiFi connections. I'm pretty sure this is really really newbish, and I really do apologize. Sorry guys.
