I'm having a VLAN problem I believe. We have a Sonicwall F/W using several sonicwall Access points for our wireless. They all sync to the firewall. We have that Firewall and 3 switches Switch A,B,and C. There is a connection from the F/W to Switch A, a connection from switch A to Switch B in the same rack. Switch C is in another part of the facility and connected via fiber. most of the Access points are plugged into switched A and B and they work. we have 3 APs plugged into switch C that I cannot get to connect. From any PC I can connect to and ping siwtch C and get into its Web login but not the AP's plugged into it. The sonicwall created a VLAN for each SSID and we have VLAN 100, 200, 300, 400. On Switch A and B its set to have ports 1-24 tagged for all those VLAN ID's so I set switch C up the same way and yet I cannot connect to them. What am I missing?
