Ndiswrapper working fine with hw, but no networks found

I have used ndiswrapper successfully with my: "Intel Corp. PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04)" at my school with my 2.6.8 kernel and Debian.
Then i decided to compile a new 2.6.10 kernel, and I compiled a new version of ndiswrapper (1.0) as well, and linked it with the Windows XP drivers as I did before.
I am able to load the module successfully (dmesg):

Code:

ndiswrapper version 1.0 loaded (preempt=yes,smp=no)

ndiswrapper: driver w70n51 (Intel,04/26/2004,1.2.2.9) added

ACPI: PCI interrupt 0000:02:02.0[A] -> GSI 11 (level, low) -> IRQ 11

ndiswrapper: using irq 11

wlan0: ndiswrapper ethernet device 00:0c:f1:21:69:0a using driver w70n51

wlan0: encryption modes supported: WEP, WPA with TKI

But when i use iwconfig I am unable to find any networks to connect to. The network must be running fine, because every-one else is able to connect and it worked fine with me before.

iwconfig:

Code:

wlan0    IEEE 802.11b  ESSID:off/any  

          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:00:00:00:00:00  

          Bit Rate:11 Mb/s  

          RTS thr:1600 B  Fragment thr:2344 B  

          Encryption key:off

          Power Management:off

          Link Quality:100/100  Signal level:-69 dBm  Noise level:-256 dBm

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

          Tx excessive retries:0  Invalid misc:0  Missed beacon:0

I have also tried to go back to kernel 2.6.8, and compile ndiswrapper to run on this kernel. It does the same thing.

where is exactly ur problem, cause the iwconfig output looks fine. what tells ya
iwlist wlan0 scan

Sorry, I just realized that I should probably place this thread in the sub forum. But anyway.

It actually gives me the two accesspoints on my school:

Code:

wlan0    Scan completed :

          Cell 01 - Address: 00:04:75:65:7C:F4

                    ESSID:"Bygning C - 1.sal"

                    Protocol:IEEE 802.11b

                    Mode:Managed

                    Frequency:2.412 GHz (Channel 1)

                    Quality:0/100  Signal level:-50 dBm  Noise level:-256 dBm

                    Encryption key:off

                    Bit Rate:1 Mb/s

                    Bit Rate:2 Mb/s

                    Bit Rate:5.5 Mb/s

                    Bit Rate:11 Mb/s

                    Extra:bcn_int=100

                    Extra:atim=0

          Cell 02 - Address: 00:0A:5E:08:A9:19

                    ESSID:"Bygning C- 2.sal"

                    Protocol:IEEE 802.11b

                    Mode:Managed

                    Frequency:2.437 GHz (Channel 6)

                    Quality:0/100  Signal level:-77 dBm  Noise level:-256 dBm

                    Encryption key:off

                    Bit Rate:1 Mb/s

                    Bit Rate:2 Mb/s

                    Bit Rate:5.5 Mb/s

                    Bit Rate:11 Mb/s

                    Extra:bcn_int=100

                    Extra:atim=0

But priorly it detected the best accespoint and used it automaticly. How do I get it to do it again?
And how do I set my card to use one of the accesspoints.
iwconfig wlan0 ap 00:04:75:65:7C:F4
doesn't have any effect.

the scan went fine, so ya wlan should work :>

so the command

iwconfig wlan0 ap 00:04:75:65:7C:F4

worked, no error output, but u cant use this net? are u sure?

does it work when u try to set the essid instead of setting the ap

When I set the essid it seems to work:

Code:

iwconfig wlan0 essid "Bygning C - 1.sal"



iwconfig:

wlan0    IEEE 802.11b  ESSID:"Bygning C - 1.sal"  

          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:04:75:65:7C:F4  

          Bit Rate:11 Mb/s  

          RTS thr:1600 B  Fragment thr:2344 B  

          Encryption key:off

          Power Management:off

          Link Quality:100/100  Signal level:-52 dBm  Noise level:-256 dBm

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

          Tx excessive retries:0  Invalid misc:0  Missed beacon:0

But I can't get any ip when i use dhclient, so something is wrong.

Could it be because the quality is 0/100 in iwlist?

i have this exact same problem, similar hardware, same distro/kernel, only my "iwlist wlan0 scan" brings up nothing.
here's what i have:

iwconfig wlan0:
wlan0 IEEE 802.11g ESSID:off/any
Mode:Managed Frequency:2.462 GHz Access Point: 00:00:00:00:00:00
Bit Rate:54 Mb/s Tx-Power:16 dBm
RTS thr:2347 B Fragment thr:2346 B
Encryption key:off
Power Management:off
Link Quality:100/100 Signal level:-10 dBm Noise level:-256 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

iwlist wlan0 scan:
wlan0 No scan results

any ideas?
