Hello,

We have just moved house and now have Comcast cable internet (motorola surfboard modem) which is plugged into my Airport Express. I have a MacBook, which detected the new information, adapted, and connects to the internet flawlessly. My husband has a PC laptop equipped with Vista and although it connects to the Airport, it cannot connect to the internet. We've done Vista diagnostics, but we suspect there is either some setting on his PC which isn't allowing the connection or else I've done something to the Airport to disallow internet access to strange computers. We did disable all security on the airport (which is how he was able to connect to the airport) but he can't get to the internet through the airport.

Any thoughts?

Also, our kids have a desktop PC and we'd like that to connect to the internet, too. We figured we'd put in a wireless thingy so it detected the Airport, too. But perhaps there's something better which could solve all the problems?

Thanks in advance!

Depending on your ISP, it may not be Vista capable (a call to them might reveal something). But most issues with ISP's revolve around IPv6 compatibility and the DHCP Broadcast Flag (on by default in Vista, off by default in XP). You can turn off IPv6 in your network connections properties, and can disable the DHCP Broadcast Flag with this KB article: http://support.microsoft.com/default.aspx/kb/928233

As for the desktop, a wire will provide a more reliable connection, but if that's impractical you can get a wireless adapter. I prefer those that are installed in the PC, feeling that they are a bit faster than those that plug into a USB port.

Wow! Thank you! :huh: That did it for DH's laptop! My daughter also has a laptop and DH has tried the above trick but, although her laptop (also Vista) is connecting to the airport, it's not connecting to the internet. We tried everything at the link above, but it's "connected to the home network but cannot get to the internet." What's odd is that's the same issue with DH's laptop which was fixed by the above.

Generally this fix works for a device that doesn't know how to deal with IPv6 or the DHCP Broadcast Flag - and most commonly I've found it to be the ISP that isn't fully Vista compatible. But, this can also be an issue with your router or your modem.

First, I'd suggest cycling the devices in this order:
1) Turn off the modem, router, and all the PC's
2) Turn on the modem and wait 3 minutes
3) Turn on the router and wait 3 minutes
4) Turn on 1 PC and wait 3 minutes
5) Turn on the next PC and wait 3 minutes
6) Continue for the rest of the PC's

If that doesn't fix it, then I'd suggest trying to repair the connection on the PC that doesn't connect. Let us know how it works for you.
