I've just got back home and tried to connect my laptop to my wireless network. It finds the router fine and connects without problems, but the IP address isn't right and I can't browse or get email.
The only thing that has changed since I last connected at home is that I've been at a hotel, where I searched for a wireless network and connected to it. I was then presented with a webpage where you had to pay for access, so I didn't bother going any further. I'm guessing the IP address that has been set on my laptop is the one the hotel network gave it.
I've checked the router config and it's all fine and as before with DHCP etc. I've done a ipconfig /release and /renew on the laptop but it just keeps coming back to the odd IP address. I've removed the hotel network from the list of preferred networks and if I search only my home one is found.
So why is my laptop refusing to pick up a correct IP? Has the hotel network changed something in the registry or on a config file somewhere?
