I have an RT-1900 that i configured for a client of mine. It worked great. I was able to set up the wifi and add a guest network that couldn't get to any of the other devices on the network. So now that they recently installed a sonos speaker system on their back Patio/ outdoor bar. They were having issue's with an existing Belkin AP/Router that was installed by someone else. The Belkin was configured for AP mode. The issue is that when a guest would join that AP they would to get to anything on the lan. IE the sonos system and hijack it. I tried to configure a guest network on the belkin but it didn't work. So i brought another RT-1900 and set it up in AP mode and configured the Wifi network and then a guest Wifi network. However on the guest network i was still able to get to anything on the LAN. After doing some research this makes sense since the second RT-1900 wouldn't know what reference when in AP mode. So my question is there anyway that I can get this to work with the two RT-1900? What config would i have to do. I'm pretty good with Simple network setups but need a little help for this.
