Radio Interference, Technical Support

•Make sure that the radio is not surrounded by many strongly reflecting (metallic) surfaces. With multiple reflecting surfaces between the radio in question and the target radio, a severe “multi-path” problem may introduce high bit error rate despite a strong “Signal Strength”.

•Make sure that there is not a condition of severe packet collision caused by a “hidden node” problem. A “hidden node” problem is the situation where the RF signal from two or more Station radios cannot reach each other (but can reach the AP). In such situation, multiple Stations may attempt to transmit data packet to the AP at the same time and therefore cause packet collision. To solve this problem, either re-arrange the Stations in question such that the RF signals are mutually sensible by all Stations, or turn-on the RTS/CTS protocol by setting the “RTS threshold” on the “Station” sub-tab to a reasonably small value (500, for example). There is no guarantee that the packet collision can be entirely eliminated by invoking RTS/CTS protocol, but the severity can be reduced enough to see visible improvement of the link quality.

Radio Interference

You may be able to eliminate RF interference by trying the following:

•Find the “channel” used by the source of the interference and coordinate your network and the interference source to be on channels that are at least 20MHz, but preferably 30MHz, apart.

•Reseat the AirEZY-2411-BT radio to a location where the interference is minimized; in general, increase the distance between the wireless computers and the device causing the radio interference.

•Avoid using 2.4GHz cordless phone in the vicinity of the radio

•Keep the computer with the AirEZY-2411-BT radio away from the microwave oven and large metal objects.

•Consult the dealer or an experienced radio technician for help.
