Hi all,

Faye's cousin is having problems connecting to her Sky Broadband router. The router is a D-Link router, but the model is unknown. I do know that it is running the Sky firmware version sky_1.11

She can connect to the Internet through the wired LAN, but not through the wireless, however, her house mate is using the wireless flawlessly.
She can connect to the wireless and can obtain an IP address, subnet mask and it know the default gateway. The router can see the laptop wireless too.
The Access Control page shows her laptop's name and MAC address, but the "Turn Access Control On" checkbox is not ticked.

When only connected using wireless she cannot connect to the routers web interface, nor can she ping the router reliably - She gets a request time out/host unreachable.

I've done screen sharing and can't see anything obvious that I've missed, I'm really not sure where next to turn...
She has a Windows Vista laptop (not sure on the model or Vista version)

Any help would be amazing!
Thanks very much,
Ben

Does the laptop connect to other wireless networks all right? What OS is the other laptop running? What encryption method is the router using? Would it be possible to try connecting with no encryption?

Any chance of testing the wi-fi under Linux (Live CD)?

I think the other laptop is probably Windows of some sort.
The router is using WPA2.
The laptop is fine on the uni network.
Linux is probably a no no unless I can get to Swansea...

The other laptop is running Windows 7

Is that the housemate that gets an IP or Faye's cousin when connected via wireless?

When connected to wireless, Faye's cousin can get an IP address.

Does she have any security software, specifically a third party firewall? Which security zone is the wireless connection assigned to?

Is it a Dell? or have McAffee on it?

If so disable the AV program and give it a go.

She does have McAfee, I'll get her to kill that. To my knowledge there is no other security software.

Just seems odd that a wired connection works...

Each interface is configured completely separately. When you first connect to a new network, Windows asks you what type of connection it is. For example, if you choose Home then the security is set a lot lower.

Some basics here, but try a reboot in Safe Mode with networking, see if that changes anything. If it works, it's a non-core process buggering things up. If it fails, then it's something integral to the OS. Also, just check that the notebook actually supports WPA2. Try dropping the wireless security to WPA or even WEP and see if that changes things.

Given symptoms, could do worse than resetting the tcp/ip stack, as I've come across machines that gave all signs of connecting but then couldn't even ping the router. Go into CMD and type 'netsh winsock reset' to do the reset.

Has anyone suggested updating the wireless drivers on the laptop? It is Vista after all
Sorry if that has been covered but I couldn't see any reference in the posts.

Thanks everyone, I've not had a chance to speak with her since last Thursday. I shall suggest some of these things next time I talk to her

It might also be worth checking the logs on the router, to see if there are any obvious errors in there.
