Welcome to the forum, sorry about your connectivity issue. Anone else? Yes. You can search the forum for internet problems. Theories abound, plenty of wild speculation. But no one has posted a solution that I recall. One popular assumption is a problem with the radio system but TCAM replacements do not always solve the problem of dropped connections. Possible server issues or outages with the ISP that is handling Volvo's system locally. That idea doesn't stand up to scrutiny, though.
 
Have the same problem.started 6 (!) months ago. Meanwhile I found out, that the problem is connected to temperature and strong vibration. Very cold or very hot : Problem occurs - can "switch" it on/off by forcing strong vibrations. Imo, it is a problem on the printed circuit board of the TCAM
That is a hardware problem. As noted elsewhere, most likely a faulty data comms wire or module. Apparently quite rare and equally difficult to diagnose.
