I have a setup with 1 SA520w and 3 AP541n's in a residential network. I have setup 3 VLANs wired and 3 wireless VLANs. they are 1, 10, 20. I am using the SA520 as the DHCP server for all 3 subnets, "192.168.13.0"-"192.168.26.0"-"192.168.39.0", Initially the DHCP would not pass through to wireless clients but after upgrading the firmware it does. initially at boot up the AP's clients connecting to the AP's get an address for the any of the networks but fail every so often through out the day. The wired network seem to have no problem although I could not get the DHCP to work with a Netgear switch in vlan mode. Has anyone had similar problems with the SA520's DHCP and what did you do about it.
