my windows xp sp1 desktop is having problems accessing the router and modem. i got a d-link 624 wireless router and cable modem but can't connect to either with the desktop. the computer i'm currently using is a wireless laptop and it has no troubles accessing the internet and router. i've done the power down/reboots of both and still nothing. i can't access the router (192.168.0.1) with the desktop. when i check the network connections, the ip/dhcp/gateway info is all there but when i try and repair the connection i get: the following steps failed: purging the dns resolver cache. ipconfig /flushdns through the cmd prompt doesn't work either. ipconfig is not recognized as an internal or external command, operable program or batch file. if i bypass the router and go modem to desktop, the network connection states that its unplugged and the modem's pc light goes dark. plugging the router back in the light goes on, the data light flashes and the network cable unplugged disappears. adelphia tech support couldn't help. hope there's someone in this community who can.
