I went to my parents this christmas and brought my router with me. There and when I got back home my mbp has had problems finding my home network, I have to type it in manually almost every time. I got a zyxel router, 128bit WEP and the SSID is hidden. When I was at my parents I just thought it was because there was so many networks available that it would interfere or something, but now at home I got the same problem, it works fine sometimes and other not. I got this error message when I was about to write this, and it said something like: "Another computer on the network is using your IP-number (192.168. the IP i get from the router) Try to connect later or contact a network admin" (translated from swedish). When I saw that I was sure someone had hacked my network so I went in to the router settings and saw that only my mbp had been using it. This probably has nothing to do with my problem but anyway. Any ideas?
