Debian Lenny AMD64 Intel IWL4965 WiFi
 
Hello. Today I installed the 64 bit version of Debian Lenny. Note that the problem I have does not occur on the 32 bit version.

I installed firmware-iwlwifi from apt-get and did modprobe iwl4965. This worked on i386. However, I cannot connect to my router now unless i suspend the computer and then resume it, at which point the wifi card magically turns on. Fn+F2 does not turn it on/off as it should.

The problem does not end there. I can browse the web, but local IPs do not load. I cannot ping the router itself at 192.168.0.1, but I can ping Google's IP and DNS name.

Dmesg yields the following after the suspend/resume/connect process has occurred:

Please help.

Okay, so I set the router to have no WEP security. Now I am able to ping local address (192.168.0.1 - router). However, I still have to press Fn+F1 (put it to sleep) and wake it up in order for the wireless to turn on. Please help.

The problem seems to be this:
Code:
iwl4965: Radio disabled by HW RF Kill switch
Anyone know how to make the radio work? The function key to turn it on just doesn't respond at all. I have to suspend/resume to get rid of the kill switch error.

WolfCub 08-05-2008 10:38 AM
I am not making any progress, please give me a hand.

WolfCub 08-06-2008 07:48 PM
I upgraded to kernel 2.6.26 today and the problem persists. Someone must know something?

WolfCub 08-12-2008 02:12 PM
The problem magically fixed itself, I did nothing. Thanks for all the help.

jnorvell 01-29-2009 01:03 AM
not magic...
 
There's a little slider switch on the front of the laptop that turn wifi off and on (the HW RF kill switch). Accidentally turning this off has caused me a little bit of useless troubleshooting time as well.

Sorry nobody tried to help you in a timely way!

I am having the same issue.

Debian Lenny AMD64
Lenovo Y710

Not sure if this is the case for you, but I was having this problem because I didn't realize I had a sliding button underneath my computer that turns the wireless on and off.

BlackNinjaVirus 02-25-2009 07:03 AM
No, the sliding switch is O.K.
However, on the i386 version, I can load BIOS defaults and install Lenny, and the wireless works.

The wireless works on Debian 4.0r3, in which I still had the DVD and I remember it working when I first bought the Lenovo Y710. The only problem back then (around October/November 2008) was the video ATI HD2600. There had been horizontal static because I believe that it could not place the pixels on the wide screen correctly.

However, the wireless was fine in all distros, Ubuntu 8.04.0, and Debian 4.0r3 which tells me that when the kernel changed - it somehow disconnected/broke the wireless firmware.

*** Works with AMD64 now, after BIOS defaults. ***
I think this is due to the fact that Linux is not a Plug & Play OS, so it reads the BIOS info directly to load devices.
If BIOS is not fresh, the install will be stale.
