Hi, I have some wireless network cameras in a house that gets terrible throughput, I suspect interference. there seems to be no obvious source, since it is a continuous problem (not due to microwave oven for example). the same setup works well in a different location (not at this house). so it seems that perhaps interference from something is making the WLAN slow. 802.11G with the following wireless devices: -D-Link DIR-655 Wireless Router -Axis 207W cameras (3) -Panasonic BL-C30 camera (1) -*HP wireless printer printer is not being used during the tests with the cameras, but it is still connected to the router as a client. My question is, if the reason is band interference, how and what can I do to track it down ? I have been reading about using Wireshark and a Spectrum Analyzer such as Wi-Spy. Thanks in advance for any helpful advice.
