I recently purchased a Cisco Access Point (Aironet 1200 series 1231) and have configured it with success but the radio signal is very weak and it doesn't come with the antenna. I thought it came missing, but on the manual says very clearly that the antennas for the 2.4 Ghz are not included. Is this information correct? Why would Cisco sell this access point without any kind of antenna? It just doesn't make sense to me.
