In the BBC building (also called Queens Court), opposite Princes Quay in City Center, theres a free wireless trial at the moment.
They are offering 10mbps down and 2mbps up. First scheme that i've heard of in Hull that is totally seperate from KC (one of their selling points is "No KC Involvement").
http://www.wizardwifisolutions.co.uk/ is the operator, I think
http://www.compclinic.co.uk/ have something to do with it as well. It is unclear!
Just thought I would bring to your attention, not sure anybody has mentioned it on the forums?
Perhaps useless information, but atleast theres some hope!
