Webs’ Random Ideas

This rogue will be the death of me. I have been searching for it since 7 this morning. The entire factory power is shut off and we can still see it. So its either battery powered or UPS. Which should make it easy right?

Ha!

Lately I have been spending a lot of time at work trying to find this wireless rogue. A rogue is a wireless device that is not supposed to be in a given wireless environment. The device itself can be an AP, client, Bluetooth device, or anything putting out RF.

So I got a spectrum analyzer to analyze 2.4ghz to find this rogue. The analyzer will show anything communicating in this frequency. But the problem is that I am hunting down this rogue in a factory that produces engines. So lots of metal things that bounce RF signals everywhere.

What to do? The analyzer shows the signal decently strong at 70-90dbi, but will then fluctuate up 150 (which is a weak signal) and at random intervals. Which then makes finding the rogue damn near impossible. When the signal is at 80 it doesn’t seem to matter what direction I head, the signal never gets better than 80 but if I head out far enough in one direction it will eventually get worse.

Why are we even tracking this rogue? WiFi in the area where I think the rogue is located sucks pretty bad. In other words I think this rogue is blasting RF to the point where other WiFi devices have a hard time competing on the same channels.
