    1 PC can't wirelessly connect to BT Home Hub

    Hey peeps, would appreciate some troubleshooting advice, I have no idea what's wrong.

    Until last week I was connected wirelessly to a BT Home Hub (the original v1.0) through an Asus 138g v2 PCI card, but now my desktop flat out refuses to connect to the hub.

    Vista reports 'excellent' signal strength, and the laptop wireless works brilliantly in the same room, so I don't think this is an issue with the signal strength. The PC downstairs had a good wireless connection too.

    When I try to connect to the Home Hub, I get "Windows cannot connect to BTHomeHub" almost straight away. Sometimes if I leave it alone for long enough, it will automatically try to connect, but it'll display an Unidentified Network in the network and sharing center.

    What I've tried so far:

    Letting Windows reset the adapter IP address.
    Restarting both computer and router.
    Resetting router completely to factory defaults.
    Changing the wireless channel several times on both adapter and router.
    Updating drivers on the Asus wireless card.
    Turning off wireless encryption on the router...
    ... and changing it to WPA-PSK with a custom password.
    Turning off Windows Firewall.
    Pinging the ip of the router in command line - all packets lost.

    None of this has had any effect

    Has anyone got any other ideas? I'm very much a noob when it comes to networking, so i'm a bit out of my depth with anything beyond 'turning it off and on again', but this has been driving me nuts. Especially since I used to be able to get online ok, even though it was a little slow and occasionally flaky. I haven't been able to check facebook for ages!

    Help plz?

    Is is the wireless that won't connect or has your IP / DHCP config gone awry?

    I know in my case I occasionally had to ipconfig /flushdns - but I don't know if that would work for you?

    I've occasionally had to restart the DNS client service as well. Might also be worth checking the antenna / cable is connected to the card properly.

    Re: 1 PC can't wirelessly connect to BT Home Hub

    Just ran ipconfig /flushdns but it hasn't had any effect.

    I think it's something to do with the wireless, as the adapter isn't connecting, so as I understand it, it wouldn't be able to get the dhcp lease from the router, so it can't be a dhcp problem?

    The antenna is definately in properly

    Will try to completely remove and then reinstall the adapter drivers tomorrow, and try to install the broadcom drivers by the chipset maker.

    Thanks for the help guys Any more suggestions?

    EDIT: after resetting the tcp/ip stacks i restarted and magically the internet works, albeit very very slowly. Pinged the router and 3 out of 4 packets timed out, with one taking 21ms.

    Tried changing the wireless channel to see if the speeds would improve but it just disconnected and wouldn't reconnect.

    If you are on vista have you tried looking under network/ sharing center and found the profile that has been created for this network - delete that and try again

    Re: 1 PC can't wirelessly connect to BT Home Hub

    If you've changed either the SSID or the WEP/WPA keys of the homehub reset them to their original config (found on the bottom/barcode of the homehub)

    I had a similar issue last year and after a long call to BT this was the solution. The lad had seen it twice in XX years of service. Nobody knows why, but it works.

    Re: 1 PC can't wirelessly connect to BT Home Hub

    Hey guys, just to update, I wiped the driver off my hard drive and reinstalled it, and tried some more channel settings, and the wireless seems to be ok now, although it does take quite a while to connect to the router after start-up.

    I'm still a little wary, see if it's still ok after a couple of days. Thanks for everyone's help though
