** Description changed: Mobile broadband does not work after suspend on Thinkpad t460s with built-in Sierra Wireless EM7455. It switches constantly on and off then (the icon). The only solution I see to repair the situation is to go to Windows and switching on there (reboot or shutdown does not help; didn't try hard reset). After check in Settings > Mobile Broadband > Modem Details it looks like that after sleep modem's sim is not recognised anymore i.e.: - modem is recognised (Settings > Mobile Network > Modem Details >>> Device Details is populated correctly), but 'Modem Status' section in Modem Details window shows Carrier (nothing), Network Type: unknown, Signal Strenght: 0%, Network Status: Unknown) - that is of course with Mobile Network switch on. Restarting Network Manager does not help. My report is not filed about a specific source package so if someone know which packages to point to it would be helpful. Also I don't know how to use cli to check sth. so help needed. PS.1. This behavior is featured in archive / net in different combinations (lid, work only after suspend, and so on). - PS.2. The error occurs also every time in newest Fedora, EndeavourOS (Arch based) and Manjaro (custom kernels, Arch based). + PS.2. The error occurs also every time in newest Fedora, EndeavourOS (Arch based) and Manjaro (custom kernels, Arch based). Debian live hangs on suspend as Ubuntu before so I can't check. PS.3.
