I've been doing a lot of googling and experimenting over the last few days, and am almost ready to just punt and go buy a newer wireless router; but I thought I'd post here as one last attempt. I've had a working wireless network in my home for about 1.5 years now. The router is a Netgear MR814v2 router (it's an 802.11b model), and I've recently upgraded it to the latest firmware version. I've been connecting to it (wirelessly) from my TiBook with a regular Airport card for a long time, with no problems. So the router basically "works". I got my wife one of the new 14" iBooks for Christmas; this model comes with the Airport Extreme card (802.11g) built-in. I can connect to the wireless network in the sense that I get "bars", but can't actually get to the internet. I can't remember the exact wording of the status message (I'm not near that computer at the moment), but it's the one that says you're in the wireless network but you didn't get an IP address. I do, however, know that the iBook's wireless card works because I was able to -- in the name of science -- get into a couple of neighbors' wireless networks and do some web browsing. So all of the components seem to be basically working. But there's obviously a configuration problem of some kind in the mix. I do have 128-bit WEP enabled, and am only allowing access from the PowerBook and iBook by restricting the router to those two MAC addresses; but I've also tried disabling those features and leaving the router "wide open" -- no luck. I know that this is a lot of information, but I wanted to let you know what I have and haven't tried yet. I'm more or less at the point of just going to the store and buying one of Netgear's newer 802.11g routers (e.g. the WGR614). Any last-minute suggestions would be appreciated, though.
