 |
|
Hi,
although I've searched all the forum and wiki / google, I can't find any solution to my problem - I can't get my WiFi working - card Intel 4965 a/b/g/Draft-N (iwlwifi driver)
lspci:
| Code: | 04:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
0c:00.0 Network controller: Intel Corporation Unknown device 4229 (rev 61) |
I have emerged iwlwifi with ipw4965 USE flag.
The problem is that my computer can't see any wireless device - it doesn't matter if I have loaded the module or not.
iwconfig - with/without the iwl4965 module:
| Code: | eth0 no wireless extensions.
lo no wireless extensions.
sit0 no wireless extensions. |
dmesg after loading the module:
| Code: | iwl4965: Intel(R) Wireless WiFi Link 4965AGN driver for Linux, 1.1.17ds
iwl4965: Copyright(c) 2003-2007 Intel Corporation

wmaster0: Selected rate control algorithm 'iwl-4965-rs'
wmaster0: Failed to initialize wep
iwl4965: Failed to register network device (error -12) |
But something strange happens when I switch the wireless switch in my laptop off, and then on - any rmmod, ifconfig or iwconfig command stops responding - and even killall -9 can't kill it.
dmesg after off-on:
| Code: | iwl4965: Detected Intel Wireless WiFi Link 4965AGN

You're missing WEP support. Add CONFIG_IEEE80211_CRYPT_WEP to your kernel, either built in or as a module, and CONFIG_IEEE80211_CRYPT_CCMP and CONFIG_IEEE80211_CRYPT_TKIP if you want to be able to use any encryption stronger than WEP (highly recommended).
I don't know what's causing the kernel oops; I'd chalk it up to the iwlwifi drivers being relatively new.

Unfortunately it doesn't solve my problem

Still no wlan0 device :/

Interesting, to say the least. Do you have CONFIG_CRYPTO_ARC4 enabled or modularized, and the module loaded if the latter?

Well, I had the same problem, but I have an Acer laptop, so I had to install the acer_acpi driver to make my wireless lan visible.
What kind of laptop do you have?

Unfortunately acer_acpi doesn't work for me - I have a Compal FT00 Barebone.
I have discovered some other strange thing - when I reload the module, I get a kernel error:

My card works perfectly under Windows XP Home Edition, so it isn't hardware problem.

This also happend with me, but looking at:
https://forums.gentoo.org/viewtopic-t-577050-highlight-.html
I found out, that it really depends in which order the modules are loaded! And be aware, i also had to rmmod mac80211 before loading all the crypto dependencies, then i could easily modprobe iwl4965. |

Yes, that did it  I've read that topic, but before iwlwifi update that has failed - I didn't thought about doing it once more
Thanks for Your help
