Just completed my upgrade to 12.04.1, from 10.04 LTS using the upgrade in the downloads manager. I tried the 12.04.1 release in a USB stick trial, found that the wireless problems could be corrected & I could connect my network printer...so took the plunge .took approx. 20 min. download @ 1135 mB/s on our fiber network, & about a 1.5 hr. install & cleanup. Reboot was clean into the desktop & wireless was up & running thru my router ..no effort. I encountered a problem getting my network printer to work ,but did a reinstall of the CUPS driver for the Canon MP500 printer & a sub-menu came up to allow me to specify the network printer. I wish to thank all the devs that worked on this version, making it a clean upgrade !.
