Alinuxnoob · 06-15-2005, 08:38 AM

I upgraded my kernel using my old .conf but some how my wifi is not working anymore.. I have a netgear MA111.

When I run
/etc/init.d/wlan start
Starting WLAN Devices: FATAL: Module p80211 not found
Failed to load p80211.0

when I run
iwconfig
lo no wireless extension
eth0 no wireless extension
sit0 no wireless extension

It use to work and im only using mac filter for wireless....

when I run
dhclient wlan0
sit0: unkown harware address type 776
wlan0: ERROR while getting interface flags: No such device
sit0: unkown hardware address type 776

I don't know if this helps, but maybe you'll have a look at it: http://www.linuxquestions.org/questi...icle&artid=239

I follow the instrctions but it gives me error
/bin/sh: ngcc: coomand not found error 127

and I been using the default path for installing the modules and I am new to debian so I dont know if that is the correct path
linux source directory [lib/modules/2.6.11.12/build]
module install directory [lib/modules/2.6.11.12]

ok I been looking around now im actually pointing it to my kernel /usr/src/linux2.6.11.12
but Im having a hard time finding module install directory

Well I think I messed my PC now think I have to format and make sure that USB wifi gets installed cause it gets detected before I upgraded. kernel.... but I found some info about my error

says that I have to

ln -s /usr/bin/gcc /usr/bin/ngcc

did and gets farther but gives me a error about nl

so whatever cluess what to do since I'm getting no support or just not enough time to sit around I did
ln -s /usr/bin/gcc /usr/sbin/ld

now before I can make config it gives me a error

collect2: ld returned 1 exit status
./Configure: line 246: scripts/make.opts: No such file or directory

Well Dont even know why im putting this in here cause gonna have to wipe it out...

and guess there is not enough docs to try to troubleshoot a error message....

No wonder Debian is falling behind not enough users.....

Hey,

Don't panic.

Did you follow proper procedure when you updated your kernel?

Alinuxnoob · 06-16-2005, 10:41 PM

Yup this is what I did

Code:

1 cp /boot/config-2.6.11.9-chw-4 .config 
2. make menuconfig
3. Choose processor and compile to your own processor type
4. Remove anything that you dont need example (laptop support, ISA, PCI express)
4. Save Configuration
10. make-kpkg kernel-image

but couldn't get a answer and didn't know if what I was looking for was right cause I was lookin @ stuff that was dated back in 2003 and 2000.... and how you should up2date and then install fixed it..... Hmmm only problem is that im using debian...

Ahhhh I just readed up ln - makes like a short cut....

But kinda gave up on trying to figure out why it didn't get install when I upgrade my kernel using the .conf file that I backed up.

and right now im looking @ menuconfig and I can't find anything that says Prism2.5 USB

only took 10 mins to reinstall so I did and just recompiling agian... using the .conf that of the new install
for reference where would modules directory be? and is this only for debian? cause I dont think the default path of wlan-ng is correct..?

I have no experience with 2.6.11 (mine is 2.6.10), but
cp your.old.config .config
make menuconfig ????? (make oldconfig is correct!?!?!) (maybe I am wrong)

Debian has modules at
/lib/modules/`uname -r`

downloaded a later version and was able to complie and install... the one that I was using was that had problem is linux-wlan-ng-0.2.1-pre26.. went to pre25 and no problems....
