Previously our core switch was a 3 Com 4500 series which our access points connected to via power connectors these AP's are from HP and basically they are capable of broadcasting 2 SSIDs one was for LAN (172.22.*.*) and the other was for Internet (192.168.1.*) for guest users, Once you authenticate to any of these SSIDs you'll be connected to the respective network. The configuration on the 3Com was basically setting the AP ports on the 3 Com to Trunk and setting the LAN VLAN to "untagged" and the Internet VLAN to "tagged" on those specific ports used by the APs.
Last week we upgraded to a Dell Power connect 7048P switch to take advantage of the POE capability. While the switch works as intended with users directly connected to the switch, we're having an issue with our access points. While we get the SSIDs we cannot get an ip and connect to either the LAN or INTERNET network wireless, we don't believe it's an issue with the APs since all they do is broadcast the SSID and connect you to either LAN of INTERNET.
So far I've set the ports to general and "tagged" for internet & "untagged" for LAN and the various combos of tagged/untagged with Access & Trunked modes all to no avail. I'm new to Dell switches and more familiar with the automatic tagging in the Cisco IOS, so any assistance would be appreciated. I'll upload the configs soon.
