Title:
Mobile broadband does not work after suspend on t460s with EM7455
Status in linux package in Ubuntu:
Confirmed
Bug description:
Mobile broadband does not work after suspend on Thinkpad t460s with built-in
Sierra Wireless EM7455.
It switches constantly on and off then. The only solution to repair the
situation is to go to Windows and switching on there.
After check in Settings > Mobile Broadband > Modem Details it looks like that
after sleep the modem is not recognised any more.
