I'm trying to get WWAN - Mobile Broadband - to work at my X301. It has a build in wireless modem Ericsson F3507g.
First I tried using Lenovo Connection Manager without any luck - so I uninstalled if. After that I tried setting up a dial-up connection. A few times I have succedd to get the connection up - but most of the time I get the error message 734 - The PPP link control protocal has been terminated.
