Recently here at MetaGeek, a broken WiFi card wreaked havoc on the 2.4GHz spectrum. Each network (a total of 10) had little to no connectivity due to this interference. Were it not for our Wi-Spy 2.4x we would not have been able to identify the culprit. The following is a screen capture of what the card was doing. It was broadcasting similar to a frequency hopping device, putting an 802.11b signall on every WiFi Channel.
Turns out, the device was a Toshiba Laptop with a broken WiFi card. It somehow malfunctioned one day, ruining network connections on every channel.
This is a big deal. Netstumbler, wireshark, or any other software application will not be able to catch what this device is doing. Interference like this is virtually invisible to anyone without a Spectrum Analyzer.
Network interference hurts company productivity. Here is how a fellow customer resolved a similar issue.
Now you understand how the Wi-Spy 2.4x could pay for itself several times over!
Andy Rauer of the Ontario Science Centre, has 50 Shuttle X PC’s, of which he has had 4 of them fail similarly causing trouble for everyone. They have a PN18 Wifi Card. Here is what he said:
The problem was the PN18 WiFi card, installed in a Shuttle-X PC. We have about 50 of these units, where about a dozen or more, might be on at any one time. Of the 50 computers, I’ve now seen the wide spectrum RF from about 4 units.Usually only after a few days of continues operation
