I need some advice please? I have a wired router with an attached Wireless Access Point (ZyXEL WAP3205). The WAP is centrally located in a hallway cupboard at a height of approx. 6 feet. It has two of the short standard rubber-duck antennas. I am having some trouble with signal quality inside my home, which is solid brick construction. I have 4 IP cameras, two of which send a clear signal but the other two struggle to maintain good signal strength (probably due to the number walls through/around which their signals have to travel in order to reach the WAP). To overcome this problem I was intending to purchase a higher gain antenna, such as 7dbi or even 10dbi - see here [URL]http://www.ebay.co.uk/itm/170929276954?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649[/URL] However, where is it best to place the antenna - on the WAP or on the cameras? I had assumed on the WAP but would appreciate confirmation. Also, if on the WAP then should I replace both of the short rubber-duck antennas with larger ones?
