Ghost wireless network in network manager

Question

Hello everyone, I've been having a weird issue on my laptop recently; it may have coincided with the recent network manager upgrade, but I'm not sure, I haven't been in classes this month, so I haven't used wireless much. Anyways, now, when ever wireless is enabled, I see a hidden network all the time. At first I thought it might be a new network on the block, but no, there's no actual signal tied to it. I've tried searching here and on google, but sifting through the results proved to be very difficult because it brought up people having problems trying to connect to a hidden network.
Any thoughts on the issue would be most appropriated.

Hi Stephen,
Of course without doing a Site Survey these recommendations are purely speculative :) The choice of Antenna type would likely be to go with a Directional for this type of coverage.
With the directional antennas, you can divert the RF energy in a particular direction to farther distances. Therefore, you can cover long ranges, but the effective beamwidth decreases. This type of antenna is helpful in near LOS coverage, such as covering hallways, long corridors, isle structures with spaces in between, etc. However, as the angular coverage is less, you cannot cover large areas. This is a disadvantage for general indoor coverage because you would like to cover a wider angular area around the AP.
Antenna arrays should face in the direction where the coverage is desired, which can sometimes make mounting a challenge.
From this excellent doc;
Omni Antenna vs. Directional Antenna
