I am looking for some help and possibly a point in the right direction. I have installed two other WRT54Gâ€™s in home settings and thought I knew my way around the box pretty good. I was trying to install a new WRT54G V3.0 in a apartment building with free high speed internet. The wireless network went up just fine and I soon had 4 computers talking to the WRT with a solid signal. But when I plugged in the internet cable the internet light lit up but I was unable to access the internet on any of the computers. The PC's all came from other places which did have linksys wireless products and worked fine. When I plug the cat5 directly into a NIC on any of the PCâ€™s they are able to access the internet just fine. I talked to a fine foreign gentleman with poor English skills at Linksys support who ran me through all the rigmarole of â€œIs your power on? etc.â€ and finally told me that I was getting a private IP address and that the WRT can not handle it. I find it hard to believe since with netstumbler I see 6 other wireless networks, two which have not even changed the SSID from linksys. This is a large apartment complex and I am sure the networks are on the same floor. My DNS server is coming back with an address of 10.0.0.X which I know is a private range. I upgraded to the most current linksys firmware and then to HyperWRT but no joy. Spent at least 6 hours messing with the thing changing every setting I could in the box and still no luck. Any idea where to look next. All the apartment manager said is that the internet is working and they have no responsibility after that and he sees a lot of blue boxes in the apartments.
