Analyzing types of 2.4GHz signal in the air.

[NeoPTLD]

I'm in the city and there are a lot of apartments units within the 50' radius, so there is bound to be a lot of WiFi users.


I leave it at CH11 and it gets good signal strength within the range it is intended to serve, but every once in a while I lose signal completely and I can't even connect to my access point even with my laptop right next to the router.

If I change the channel far away, (5, not 10) connectivity is restored.

Could other WiFi devices create signal so strong that it will prevent me from connecting to my router a foot away? What might the source be?

Is there a device that can scan the waves in the range and see what it is (i.e. Bluetooth, WiFi, cordless phone, other ISM devices)

This. The 2.4 Ghz spectrum is so crowded it's not even funny anymore.

A spectral analyzer will show you just how bad it is. Net stumbler is good enough to show signal to noise ratio. If your in an apartment scenario there isn't much you can do.

5 feet is way too close. Read the sticky.
