I have the WRT546 wireless and haven't had any problems....till now. I bought my wife a new PC and when I try to hook it up, the computer cannot find the router. I named the router and can find it and hook up to it with her old laptop, but it seems to be hidden from the new one. I'm pretty sure I did something in security to hide it but I don't remember what. I went into the router manually and added the Physical Address of the new PC and got nothing. I used the cable to hardwire the PC to the router because I thought that would run a cycle(?) and set the laptop up to run wireless...wrong. Is there a way to find, rename and hook the new PC up (wireless), or do I have to erase the router (if that's possible) and start from scratch? Thanks Wanna kill these ads? We can help!
