So here is the issue. I split an interest connection with the downstair person. We have a cable modem hooked up to a Dlink DGS-2205 then from there we each have our own airport extreme. He moved in first and his was working great, now I plugged mine in and his won't work. I tired resetting the Dlink and the cable modem, along with the airports but with no luck, where am I screwing up? I can only get one airport working at a time it seems, is this a limitation of the Dlink, the cable modem or me Thanks for any help!
