Anybody outhere had experience problem with non-cisco antenna connected to Cisco AP? I had this one external antenna 12 DBi outdoor omni that connected to Cisco AP1242AG - LWAPP. The performance that not really realistic and the signal keep showing intermittent when measure by wireless monitoring tools. Please note that the AP is controlling by WLC and it is configure by select the type of antenna "external" with diversity mode. I did the measurement inside the WLC to be "24 x 0.5 Dbm" equal to 12 DBi for that particular AP.
My question are,
a) Are cisco AP really not capable when connecting to non-cisco antenna?
b) Do i had to change my configuration set up in the WLC.
c) Any missing information that need to be include when connecting to non-Cisco antenna
