After moving cities, I am having trouble using my 2 yr old Linksys WRT54G2 wireless router with a new ISP (AT&T). I'm using a Mac w/ Leopard. I can see the router displayed under network options, it will show that is connected to the router, but I've got no internet. I've only got internet if I am plugged directly into the modem. The router will not assign an IP address. Occasionally, I will get ONE of my three computers onto the internet w/ wireless. I have reset the router (i.e. instead of my old SSID, it's now just "linksys"). The router gives off a signal (i.e. it shows up as a network option for my airport). If I use the linksys CD, I walk through the installation/configuration and it results in "Error 301".
