Ok, this will be a challenge then the desktop which is not working has now way to get a wired connection to do an update. The NetworkManager-wireless rpm from the install dvd was installed. The one I downloaded to try and install has 7_3 in it's file name, original installed rpm has only 7 in it's name. So in other words this will be fun. I will let you know if this fixes the issue. The install DVD's were 7.3.1611. I don't think this is going to solve this issue, but I will be happy if it does. I will update here as soon as I have tested this out to let you know yeah or ney. Thank you for helping toracat.

The solution did not fix the problem. NetworkManager-wifi was installed already. Upgrading the package did not fix the issue.

I uploaded a zipped text file with the dmesg of the error and why the kernel is failing to load either the driver or firmware. The pertinent part I will plaster here since I feel like this was not looked at before giving me this NM-wifi fix. I am not a guru, but I am also not a noob. I am trying not to sound disrespectful here. Please don't blow this off solving this issue could actually help a lot of people out there. Thank you again toracat.

dmesg lines that scream failure:

[ 12.064396] iwl4965 0000:06:00.0: bad EEPROM signature,EEPROM_GP=0x00000007
[ 12.064398] iwl4965 0000:06:00.0: EEPROM not found, EEPROM_GP=0xffffffff

[ 12.064439] iwl4965: probe of 0000:06:00.0 failed with error -2

toracat what does that mean? the full dmesg is in the uploaded tar file. Thanks again.

Does module option "debug=1" emit additional info?


beowulfe1971 (reporter)

emits identical to what I uploaded in the text tarball. I will print it out here in full pasted up.

dmesg is:

Thank you for giving me something to check kabe.
I really do appreciate anyones help this one is frustrating.


kabe (reporter)

Is iwl4965-firmware package installed? I guess so.
Is there any BIOS (EFI) settings which mucks with onboard EEPROM?

Google suggests that the line would normally say
>> iwl4965 0000:06:00.0: Detected Intel(R) Wireless WiFi Link 4965AGN, REV=0x04
nof 0xFFFFFFFF. Likely trying to read a from a memory void?

>> iwl4965 0000:06:00.0: can't derive routing for PCI INT A
How about plugging the card into different slot?
Does BIOS settings have any IRQ settings knobs to turn?

Does ELRepo kernel-ml make it work?

I don't have the card, so for anyone, any help is limited though.


beowulfe1971 (reporter)

no irq nobs to turn in bios unfortunately.

no other slot to put it in.

Haven't been able to find any EFI settings that would set off bells.

I have ordered different card(chipset) that is known to work, just in case.

this issue is currently happening with all the Distros I have tried.

So either it's a my motherboard/wifi card combo or a kernel/firmware issue.

You've been very helpful Kabe, thank you.
