I am trying to figure out why I am having trouble connecting Back Track 3 to a couple different networks. One network is at my school when I enter the WEP key it still tells me that the connection has failed. Under windows I connect to it just fine. I can connect with BT3 to my network at the house which has WEP enabled. Is this a problem with the configuration of the network card with Linux? The other place that I am having issues with is at a coffee shop that uses a router with pre-installed software that redirects you to a login page that you have to log into first. With windows I notice it doesn't give me a connect signal until I enter my User name and Password. Though with BT3 I cannot connect even to the log in page.

Where do I begin to look to find answers to these questions?
