Hi

I am trying to get the signal strength for all available access points. I
have been playing with Paul Tobey's RFUtils but I must confess I am not very
strong in this area, so if anyone could point me in the right direction, I
would appreciate it very much.

The signal strength will only be available for the single access point, if
any, with which the RF Ethernet device is *associated*. That is, you don't
get to scan for whatever access points the device can see, as far as I can
tell, and figure out which one has the strongest signal.

But it must be possible. How can programs like ministumbler and pocket
warrior do it?

Thanks for the answer anyway.

Hi

Mikkel, you have a valid point. On a related note, If an app is written that heavily uses network comms but cant re-enable the wireless connection programatically its problematic and tedious to Force the users to re-enable the wireless connection. This also means minimizing and maximizing the .Net CF application

There must be an alternative. Hope to hear of one soon

Thanks.
 
Isn't all that happens when you Disable an adapter from the Connection
Manager just that a IOCTL_NDIS_UNBIND_ADAPTER is sent to NDIS for the target
adapter's name? Seems pretty simple...

I've completed the port myself. Here's the updated RFUtilsTest and it has
an updated RFUtils inside it that handles getting all of the SSIDs that the
adapter can hear. The test shows how to use it...

Great work!!

I'll give it a try as soon as possible.

Hi again

I got the signal strenght to work very well. But i still have 1 problem. I have managed to obtain a list of access points, and their respective signal strenghts, but when i run the method again, it keeps getting the same signal strenghts. Its like the netcard gets quiried for the access points and signal strenght, but no real update is performed getting new signal strenghts. They doesnt change until i run another program like the PocketWINC from cirond. This program seems to make some kind of network request, that updates the signal strenghts.

Do u know a way to use RFUtils that can get me all signal strenghts from the access points in 2 second intervals

Regard
Mikkel
