Acces Point Question

I am trying to add a solitary 3com access point to a wired network(Netware 6) in a classroom for a PC Tablet. I powered up the access point in the classroom,connecting it to an established active port in one wall. The access point's LED's read positive 802.11b/g connection. I installed the 3com software in my Toshiba Portege laptop, but cannot locate the access point. I have tried other wireless enabled laptops, but cannot locate the access point. I have access points on 3 portable wireless carts, and have used them in this classrrom using the same wall port with much success, but I am baffled by this situation. Any ideas?! Many thanks!

 

maybe, IT changed the encryption setting (Key, security type...), without telling you?

 

many thanks to all, had to log directly into the access point for configuration.
