Hi lip,
Why would you turn off the D-Link Router's Wireless portion and use NetGear Wireless? I would remove the NetGear and turn on the D-Link Wireless portion and plug everything into the D-Link and see what happens? Try going back to your old Network and see what happens.
Thanks for responding!

To be frank, the netgear unit seems to perform far better...basically I was using that for something else before and then I decided to integrate it into my home office network...
I have my DSL modem(it has wireless as well but I turned it off), connected to the dir-655(wireless turned off as well) which acts as a router only, then this is in turn connected with ethernet to the netgear unit which is installed in the middle level of my house (wireless on) so that I get a signal throughout the house...I live in a 5 level house and the main computer is in the basement so if I just have the wireless in the basement, it doesn't go much farther than the basement...
I hope that makes sense.
I can try switching the d-link and netgear around but the netgear has both frequencies and is generally better wireless so it would be a negative thing to go in that direction(then again, right now it's just not working right). However, the problem only seemed to occur after I upgraded the dir-655 firmware.
