Issue 1: I don't restart my modem due to load problems and I very rarely restart it anyway. This is behaviour I've noticed over quite a few months and has also occurred on the BTSync setups I have at client's places if their modem gets reset for whatever reason. I also just before Christmas did a lot of Ethernet and power rewiring, replacing power boards, got some more switches and got another ups unit. So I just had more occasion to see it happening. It still doesn't get past the problem that if a modem does get reset the UPnP gets lost (as it should) but BTSync doesn't seem to establish new ones. Issue 2: Yeah going to have another talk with him about buying a new modem/router with wireless. The wireless router is used as a wireless access point. Thinking about it now, the Linux box Ethernet cable could be plugged into an Ethernet port on the wireless router, which has an uplink cable to the internet router. I'll give him a call tomorrow and see if he can tell me. Thanks!
