I have 5 Linksys WAP54GX Access Points. We run a large network with Cisco Catalyst 3560 PoE swithces at each location to run our IP phones. When we configure one of the access points to work the wireless won't boradcast (doesn't light up on the AP) and from the switch you cannot see the AP's MAC nor will it pass packets although you can see that the port is UP/UP. Of the five AP's one works. The serial numbers are so close I doubt it's a bad batch. The one that works lights up wireless and passes packets. When plugged into a normal non-PoE switch and also when plugged into the laptop they broadcast a perfect wireless signal. Had found somewhere on the net where it said to upgrade the firmware to 1.16 (adds QoS) which didn't change anything. We tried to get help from Linksys through live chat and the support tech. disconnected after they decided our problems wasn't easy enough for them so solve in a couple minutes. Has anyone heard of this or have any ideas on how to fix this?
