New roommate has a laptop running Vista that’s having trouble getting to the internet.
I have the DSL router doing NAT, and an Airport Extreme base station in bridge mode providing the wi-fi.
My machine is running XP and connected via ethernet to the Airport so I’ve never had problems. My only wireless devices are iPhones and consoles, which I don’t have a problem with.
It doesn’t help that I don’t know my way around Vista.
I had the Airport set up with what I figure are pretty much the default settings, WPA/WPA2 Personal security. I gave him the key and he had no problem connecting to the Airport, but it only showed limited connectivity. Can’t actually get out to the internet.
I reset the Airport to default settings and recreated the whole network to be sure it was all defaults, and left it unsecured. Same thing, he could connect to the network but not the internet.
I googled a little and got random bits and pieces of who knows what kind of similar problems/solutions, and saw something about IPv6 that didn’t mean anything to me, but hey, there’s one more thing I can toggle.
The IPv6 options on the Airport are “Link-local only” (which is what it was on), Node, and Tunnel. I changed it to “Node” which adds the choice for Configure IPv6 Automatically or Manually. I left it on Automatically, updated the Airport, reconnected the laptop, and it worked! I could get to the internet.
So I figured that was the problem, so now I’d just go back and resecure the network, leaving IPv6 on Node. So all I changed once I had it working was reactivating WPA security. At which point it breaks again, and I’m back to “limited” connectivity.
edit: And I’m reasonably certain I didn’t change anything about how the laptop was trying to connect, but I can’t rule out the possibility that in my fumbling through Vista maybe I did something slightly different in connecting at various points. If you know of any obvious mistakes there, please point them out!
