Intermittent Connectivity on hardwired connection

If the hardwired devices all drop for only a second, the T3200 doesn't sound like it's fully losing the connection. Normally if it does, it takes longer than that to reconnect. Is the T3200 in a position where you're able to quickly look at it when the connection drops? Do any of the green lights on it turn off or change color? Are you on DSL or fibre? If fibre, is the fibre connected directly to the T3200 or another white box nearby?

I would also recommend contacting technical support and have them run checks on your connection. There may be something that's intermittently causing a brief interruption that their tools can see. Worst case scenario it could be an issue with the T3200 itself but I'd have them run the tests on the connection first. If it is indeed the T3200, they should be able to send out a replacement or a repair tech.
