I would greatly appreciate some help with my wireless.
The problem is that its sensitivity is very low under fedora. The network here does not give a very strong signal, but I can connect using the same card under windows. Fedora does not even see the network I want to connect to. I know the card is working in fedora, too, I was using it to connect to a different network in another place. Is there any way to increase the sensitivity, to match at least what I am getting under windows? I tried to set the "sens" option in iwconfig, but it seems it is not supported.
I am using Network Manager to connect.
I have the following card (according to lspci):
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000
Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN
Physical Slot: 1
Flags: bus master, fast devsel, latency 0, IRQ 49

And this is what iwconfig shows:
