I have a setup consisting of a main router (connected to the router of the ISP), and connected to it are 3 other routers used as switch/ap. I enabled VLAN's and virtual wireless, primarily to allow a guest wifi network on all routers. For some reason, all clients connected to any of the routers can access the internet without problems and can also access the routers (ping), but the routers that I use as switch/ap cannot access the internet. I *think* it worked some time ago (because I didn't notice the switches/aps NOT getting a time from the internet time server), but now not anymore. Anyone any ideas what could cause the switches/aps being unable to access the internet, while all clients connected to it can? Thanks! Edwin.
