OpenWRT and Guest Networks on the Netgear WNDR3700
In my house I have Debian Linux running on an old laptop acting as my router with a Netgear WNDR3700 acting as an access point (WAN port on this is unused). The AP is configured with WPA2 security, but recently I wanted to connect my Nintendo DS to the wifi network. Now the Netgear has guest networks, which is pretty much what I wanted, but it only allows the guest wifi access to the WAN port, which was useless to me. I also wanted to be able to conveniently enable and disable the insecure network with a button on the access point. Knowing that the hardware supported what I wanted to do, and having had good experiences with OpenWRT on another router in the past, I set out to see if I could make it work.
