I have a dlink di624...I hook up to cable modem...I can see both a wireless network and I can run ethernet cable from 624 to laptop....in either case I get no internet....on wireless it asks for network passcode...when entered it says not the passcode....I can run ethernet cable from modem to laptop and Im good...Ive done a factory reset on 624 but still no internet....all lights on 624 indicate its working....I cannot enter url to configure because I cant get internet through 624...any suggestions? I am replacing a failing linksys router....I know the 624 is old but worked great at last use.....thanks for any response.
