Looking at the above extracts it would seem that the wireless signal
you are picking up is a bit low.

-90 is about the connection threshold for 2.4Ghz (it does depend on
the sensitivity of the reciever)

How close are you to the wireless AP

In windows, what does the signal strength look like at the same
location of those machines?
