I have an access point behind a Sonicwall TZ-370. The Sonicwall is doing the DHCP. The Sonicwall does not have Wi-Fi. The Access Point provides the Wi-Fi. I tried to use an Asus RT-3100 Series Router set to Access Point mode for the Wi-Fi. The Wi-Fi kept disconnecting. I temporarily hooked up a Belkin F5D7130 Access Point and it works perfectly. Are there some settings in the Asus that need to be changed for Access Point mode?
