That's an entirely different can of worms.
That's what I don't want, if it means the router-router connection is wireless because (a) we have the CAT5 cable available and (b) poor wireless transmission between the two areas is the problem I'm trying to solve. > > Required topology: > > > > > > ╲│╱ ╲│╱ ╲│╱ > > ┌───────┐ ┌───────┐ ┌───────┐ > > │W L╞ CAT5 │W L╞═PC │ ROKUs │ > > [Modem]══╡A A╞═════════════╡A A╞ │ etc │ > > │N N╞ │N N╞ └───────┘ > > │ ╞═PC │ ╞═PC > > └───────┘ └───────┘ > > > > > > ¹ WNDR3400v3_UM_10May2013.pdf > > ² WNDR3400v3_UM_19June2014.pdf > > "PC" on the left side won't be able to talk to anything connected to the > right side (unless you punch holes in the "WAN" of the right-side > router). Suppose if that's your goal, it'll work fine (barring > double-NAT for the right-side devices, if that matters). Well, I *think* that that "punching" is the functionality that some routers have and others don't. I'm trying to determine whether the router Left does anything out of the ordinary other than notice rather heavy traffic out of one port. If not, then I could put our current router as Left and buy a better one for Right. I think the double NAT is essential as Left can only send to one MAC and therefore one IP address out of the CAT5 port. What I need to contradict in my previous post is that the two routers *can* use different SSIDs, because anything that roams is able to switch between different SSIDs. The Rokus don't roam in that sense, and can manually select between different networks if and when we move them about. (They are three different models with different pros and cons.) So I think what I want is something like http://smallbusiness.chron.com/run-two-routers-off-one-cable-connection-56718.html and not (so much) something like http://smallbusiness.chron.com/setting-up-wireless-routers-same-ssid-68675.html where the router-router link is LAN-LAN. But I'd be happy to try the second method instead if that meant I could keep this router. Not, however, if I had to use WEP/None for security. (I can't work out the relevance of that demand in the User Manual.) Cheers, David.
