I bought a SonicWall TZ210 and 5 SonicPoints and I paid to have it preconfigured. The SonicPoint is configured with a Guest Vlan and Secure Vlan via the x5 port and works fine if I connect a SonicPoint directly to the port (with a POe injector). Problem is when I connect my Netgear prosafe (or any switch for that matter) between the x5 port and the SonicPoints, they light up (with POe power) and the Wlans are visible to devices but "no connectivity" i.e. no internet. The Wlan adapter shows 169.254.x.x so no DHCP connection. SonicWall says it is a "tag" problem and Netgear basic support says it should work as is.
Wlan default gateway 172.16.1.1
