Modem on passthrough keeps dropping connection

[cthobbit]

I just received a new xFi gateway and since I installed it the modem,, multiple times per day, drops connection for 5-15 minutes. It's set to passthrough, because I have a gaming router, what could cause these drops? The router will be running, but it will lose its IP address and then need to eventually cycle that (or if I'm home I can release/renew to speed the fix).

[EG]

For a test, does a computer hardwired directly to the gateway device (in bridge mode) (no router in the mix) have the same problem ?

You'll need to powercycle the gateway when you make the change, and then again when you re-insert the router.
