BleepingComputer.com: Adsl Modem Router Continually Disconnects

Hi,

I've installed a ADSL modem router and several hubs at my work. The PCs all share the same broadband link through this router

My problem is the connection is continually dropped by the router. If left, it will magically reconnect after a few minutes. Otherwise I can unplug the router, plug in back in, and it reconnects straight away.

I've checked the routers setup and the disconnect period is set to 0 (always on).

Thanks for any suggestions, as my boss is losing patience!
