Very low wireless sensitivity Intel Corporation Centrino Wireless-N 1000 BGN

[duende]

Hello,

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
        Memory at d7400000 (64-bit, non-prefetchable) [size=8K]
        Capabilities: [c8] Power Management version 3
        Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [e0] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Device Serial Number <masked>
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

And this is what iwconfig shows:

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=14 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
