Lenovo N5321 gw (ttyACM0)
(rebranded Ericsson H5321gw)
This was rock solid in mint 16 after following:
http://forum.linuxmint.com/viewtopic.ph ... 21#p707130
but with mint 17.1 I can get a connection for only a short period and then it drops - sometimes instantly, usually after a second or two, once I got 15 minutes.
This is a real blocker for me - on the verge or returning to mint 16.
Anybody know how to solve this one?
