I'm trying to set up a second WLAN at home (since the Nintendo DS firmware won't connect to my WPA-encrypted main WLAN), but when I connect my second router's WAN port to one of my main router's LAN ports, the routers won't talk, and I can't connect wirelessly to the second router.
I can still see the second router's WLAN - I am just unable to connect to it. And it seems that even the main router can't see the second router, despite being plugged directly into it - I went to the main router's admin console and pinged the second router (which is receiving an IP address), but it was unable to reach it!
Does anyone know what might be wrong?
Thanks!
1WAN ports are for connecting to a WAN. You're connecting it to a LAN, so you should use a LAN port. Make sure to disable its DHCP server -- you don't want two in the same LAN. – David Schwartz – 2012-11-08T11:32:29.870
Oh, really? I figured I should use the WAN port because that's where it gets its connection to the outside world. What's the technical difference between a WAN and a LAN, then? – ekolis – 2012-11-08T13:04:16.107
A LAN is your connection to other computers and the outside world. A WAN is the outside world -- a network distinct from your local network. When you connect something to the WAN port, you are telling the router it should isolate that connection from your LAN. – David Schwartz – 2012-11-08T13:14:18.770
So my main router isn't "the outside world" from the perspective of my second router? – ekolis – 2012-11-08T14:10:17.230
Nope. It's just another machine on your LAN. – David Schwartz – 2012-11-08T15:05:25.813
