I live in a dorm where using the internet requires one to log in. I have set up an Airport Express in my room and set it to DHCP/NAT which enables me to log in one and then use wifi freely on all my devices. However, this gives insanely slow wifi speeds. If I connect directly with bridge mode I get lightning fast internet, but then I can only use one device at a time, and I have to go through a lot of logging in/out troubles to use a different device. I have tried every possible configuration I could think of... Can anyone give me some pointers?
