CB2 was the only place in the city with free wifi that I could find.
The Arts Cinema Cafe also has free wifi
The Kingston Arms on Kingston St has two PCs and wifi. Also the library at Anglia Ruskin will give you a one-day wifi account for the asking.
There's always the (slightly expensive) Copper Kettle/Agora on King's Parade. Free wifi but pricey food.
The Fountain on Regent St offers free wifi.......... and serves Leffe in a pint glass!!
Also, the Elm Tree Pub has free wifi, as does CB1 on Mill Road
The Bath House is excellent, a lovely quiet pub near the Eagle, just off King's Parade. Free Wifi, nice food.
Also, free Wifi to be had at The Snug - there's one on East Road and another on Lensfield Road.
If you're really stuck there's always McDonald's, near Market Square. You might want to invest in a good set of headphones first though.
Try the Kingston Arms on Kingston Street (15 minute walk from the station). Free wifi and a couple of screens for the public to hack away on. Beer’s not bad either.
