My D-Link DIR-615 wirelessN router usually is set automatically connect using DHCP at 40 GHz and I've had no trouble accessing the internet with my computers. Today, however, I learned that to allow my daughter's new iPhone to access my wireless network, I had to "mix" the router settings to allow both my normal network clients to continue to connect at 40 GHz and also now allow the new iPhone to connect to my network using 24 GHz. I entered the iPhone's MAC address in one of the fields available for manually adding a device to allow it to use the 24 GHz port. PROBLEM: Now I can't access the Internet with either, apparently because I failed to activate the dual mode that allows both. SO, now I can't access the router's web-based admin interface in order to re-set the router to the original settings and start over. Any help would be much appreciated.
