Wireless noise killing connections

Hello,

     I have 6 wireless devices at a location on 6 different channels. When I check the signal strength I get full bars, but when I use my wireless for long time I get bumped from the network often. I have a blue tooth device connecting to a blue tooth headset, which works crystal clear outside the range of the wireless, but in the building it has large amounts of static during any phone calls. Is there a device I can use to pinpoint any wireless interference?

You can try netstumbler, but I don't know if it also works with bluetooth devices.

Do it detect noise on the wire, and can it detect the source?

Do you have the wireless cards' power management features turned off ?

Yes, and this happens to all machines that connect. Does anyone know of a device that can determine the source of wireless interference?

What can you do to avoid interference from Bluetooth devices? The following are some tips to consider:

    * Manage the use of RF devices. One way to reduce the potential for interference is to regulate the types of RF devices within your facility. In other words, establish your own private regulatory body for managing unlicensed RF devices. The extreme measure would be to completely ban the use of Bluetooth; however, that is not practical or even possible in all cases. For example, you can't feasibly prohibit the use of Bluetooth in public areas. For private applications, you could set company policies to limit the use of Bluetooth to only specific applications, such as syncing PDAs to desktops.


    * Ensure adequate 802.11 coverage. Strong, healthy 802.11 signals throughout the coverage areas helps reduce the impact of the Bluetooth signals. If wireless LAN transmissions become too weak, then the interfering Bluetooth signals will be more troublesome. As a result, perform a thorough RF site survey, and determine the appropriate location for access points.

    * Move to the 5 GHz band. If none of the above steps solve the problem, then consider using 5 GHz (i.e., 802.11a) NICs and access points At least for the foreseeable future, you can completely avoid RF interference in this band. You'll also receive much higher throughput; however, the limited range could require additional access points and higher costs.

Thanks for the info.  So does www.cognio.com do the same thing as netstumbler?

netstumbler is free, the other looks it provides more info but is not free. Try netstumbler, see what it picks up, it may help troubleshoot.
