But bridging is only possible when the parts support it. I know a few that wish this wasn't true. So in a nutshell and to get to the bottomline I don't see this pair having a supported bridge feature.

"The place where i bought the access point told me i could bridge them WIRELESSLY, which is what i really need."

Sorry, I don't see how either.

I downloaded the manuals and the word "bridge" is not found in them. You have 2 choices.

1. Use it wired. Set it's channel to far away from the existing channel then move it as near to your intended space as possible.
2. Return it. They fibbed.
