Problem with Dlink DPR-1260

I use this as a wireless printer point and a wireless internet connection for a PC. All worked fine with XP but wont work with WIN 7 32 Premium.
Problems:Other PC can communicated with printer. But PC connected to router cannot. It might if I could download printer drivers. PC connected to dlink when I open IE 8 the progress bar moves to halfway and I get a little clock at bottom left corner of window. Firefox opens to home page but same thing with progress bar. I can ping yahoo via CMD window. I can ping my main router but cannot access it via the IP address.
I have reset this thing so many times its SAD. Dlink support site has no info on windows 7 and googling this dlink windows 7 comes up spotty at best but no answer.

What I am trying to do is get PC(kids room) connected to internet via my Netgear running DD-WRT and the printer working, like it did with XP pro.

Any thoughts?
I did unchecked the IPV6 and that did nothing, so I rechecked it.
