I have a single AIR-BR1310G-A-K9 with external antenna AIR-ANT2506 in access point mode that I am having a very difficult time getting solid coverage.
It's in a new install with the ap mounted on an external wall with the mast antenna. I only have two wireless clients that need connectivity, both are IP cameras. They are both about 250 to 300 ft. from the ap with clear line of site, across an open parking lot. One is directly to the south and the other is directly to the west.
The problem I'm having is that the mast antenna seems to be extremely sensitive in it's veritical alignment. If I mount the antenna perfectly veritical the south client connects fine but the west client gets a somewhat bad connection. If I tilt the mast antenna slightly to the west so that it's horizontal plane points directly at the west antenna then the results are exactly oppisite, the west client is strong and south client is weak.
The west client physically sites about 10 -15 feet lower than the ap, and the south antenna is the same height as the ap.
By looking at the antenna's spec's and E-Plane and H-Plane that I wouldn't have had a problem at those distances.
Part of the problem may be that the clients are wireless camera's and i'm trying to stream video over the connection. When it's good, the video is great, when it's bad the video is pretty choppy. The quality depends on exactly how I have the mast antenna tilted (it's a VERY slight tilt)
So my question is whether this sounds normal. Should I expect this type of coverage? What's the best way to fix this? Can I add a second antenna which points directly at the other client?
Is there something wrong or missing from my config? ( I noticed an external antenna gain setting in the setup which is disabled by default)
