I have noticed some connection problems lately and decided to check my connection versus an open AP near my house.
I decided to use the Sharp/Cacko Wireless monitor app, since it's referred to a lot in this subforum.
When I connect to my router, I get a very weak signal, as shown in first pic.
Frst pic shows:
------------------------
Channel -1 Speed 2
Signal 3 - 2%
Noise 27 - 26%
Quality 0
------------------------
When I connect to an open access point, (I'm not sure where it comes from, but is not my access point)
Second pic shows:
------------------------
Channel 6 Speed 2
Signal 26 - 25%
Noise 22 - 21%
Quality 3
------------------------
Edit
Added iwconfig. I edited the "Access Point" numbers.

I have my Linksys router setup with WPA personal PSK, set to 'b" only
All the settings on the advanced wireless page are set to default.
One other thing I noticed is that my ESSID doesn't show in the "Network monitor". Is that because I'm using WPA?
