Re: [Modem] Help with Motorola 3360 Modem and router configurati

Never mind ... I think I *finally* grasped the issue and it looks like the only rational solution will be to add a hub between the modem and router, and attach a spare laptop to that with an IP on the same subnet as the modem.

You don't need to add a hub or a spare computer if the router has two unused ethernet ports

Oh! So, if I connect the spare laptop to one of the router's empty ports, but set its IP to match the modem's subnet, then I can contact the modem through it? If so, then what is the second router port needed for?

Pretend you're explaining to an idiot Actually, you won't be pretending!

Thanks so much!!

Correct

Connecting the modem and router this way uses two router lan ports

Here's a picture that shows the connections

Thank you!!! Almost idiot-proof

One (hopefully) last question --- do the spare laptop AND the router now have to be on the same subnet as the modem, or just the spare laptop?

REALLY appreciate all your help, Wayjac!

If the spare laptop is the only computer you want to access the modem. Only the spare laptop needs to use the same subnet as the modem
