If you have not previously, you need to follow the instructions to setup your computer.
If you have used eduroam before, you may get a yellow bubble popping up. This usually happens the next time you use the wireless service after changing your Bristol password.
Just click on the bubble and enter:
Click OK. Your computer will then connect as normal to the wireless service.
If the bubble repeatedly re-appears then either eduroam is not correctly configured on your computer, or you are typing your username or password incorrectly. Also, if you enter incorrect credentials too many times, the system will lock you out for 40 minutes. In this case, switch off the wireless function on your computer, wait 40 minutes and then try again.
