@rm sorry for late reply. Do you use dual boot with windows, or ubuntu is the only system....
As I have a dual boot system with windows and xubuntu now, the same thing happens to me (checks password for long and doesn't connect) when I go to windows and return to xubuntu. I have worked around it be simply shutting down xubuntu once and starting again. Reboot porabably don't work. Had the same problem with Linux Mint 17 cinnamon and Linux Mint 17 XFCE too... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1220146 Title: Need support for new Ralink Wifi card - Mediatek 7630 [14c3:7630] Status in HWE Next Project: Confirmed Status in HWE Next trusty series: Confirmed Status in The Linux Kernel: Confirmed Status in “linux” package in Ubuntu: Confirmed Status in “linux” source package in Raring: Incomplete Status in “linux” source package in Saucy: Incomplete Status in “linux” package in Fedora: New Bug description: This device is appearing in some OEM machines, but driver is not yet available in mainline.
