The oddest thing. My daughter lives in an apartment and has an internet provider that works. When she plugs in her PC it gets a public IP address. The access point has only one port and other than the AP handing out a public IP address, so far so good. She bought a Belkin wireless AP. Plugged it in and it didn’t work. Different cables, different ports, crossover to WAN port, crossover to LAN port –nothing. Wireless can connect wirelessly but no way out to the internet. So, I bring the Belkin to my house with ATT AP. Plug in the Belkin with no configuration and it works just like it is supposed to. I connect with my iPhones/Pads, get to the internet through a private IP address provided by the Belkin through DHCP. Plug in my PC all of the LAN ports one at a time, just perfect. I configure the AP giving it a better password, DHCP range etc. Worked great. Wrapped it up with the same wires and took it back to her apartment. It’s the same as before. Does not work. What am I missing?
