I need to move my cable modem closer to the incoming signal to solve disconnects I'm getting (too many splitters according to the cable tech), but this means that I'd lose wired access to the signal.
I tried this before and the wireless signal was too weak to reliably pick up with my PC, but my wife's laptop and HTPC in a different room picked it up fine.
I have an extra router that I can put the DD-WRT firmware on and this got me thinking. Why not set up this extra router as a wireless bridge and repeater (assuming it can connect) and keep my PC, HTPC, and printer all wired to my gigabit switch?
This then got me thinking that I could do some extra security while I'm at it. Why not separate the two networks so that devices that I don't want to give access to my computers can still connect wirelessly to the router in the other room?
So, here's what I'd like to do (solid lines are wired, dashed lines are wireless):
What's the best way to separate these two networks? Is it even possible? Do I just leave the routing functions enabled on the second router?
