Have a look in the event viewer mate at the time it's going off and see what's going on. Hopefully it'll give you an idea of what's happening. Let us know.
The connectivity went off again last night and has not come back on, there is a lot of information in the event log but I will put up the most relevant logs, hopefully it makes sense.
