After a long time I want to connect to LAN via WiFi network and it failed. However I am able to set up the connection in gentoo-sources-2.6.32-gentoo-r7. In higher version (tested with 2.6.33) I can't make wlan0 interface functional. I am using the iwl4965 driver and net-wireless/iwl4965-ucode-228.61.2.24 in all these kernel versions. Of course I've reemerged the iwl4965-ucode in newer kernel. Reproducible: Always Steps to Reproduce: 1. Boot kernel higher than 2.6.32 2. Load all necessary modules (modprobe iwl4965 especially) 3. ifconfig wlan0 up 4. iwlist wlan0 scanning; dhcpcd wlan0; ... everything using the wlan0 interface Actual Results: iwlist wlan0 scanning doesn't work, dhcpcd wlan0 doesn't work etc. It is not possible to set connection. Expected Results: iwlist wlan0 scanning should display information about wireless network (as it does in 2.6.32), dhcpcd wlan0 should receive an IP address There is a part of /var/log/messages from 2.6.32-gentoo-r7: 2.6.32-gentoo-r7 ================ Oct 15 21:06:47 usambara kernel: iwlagn 0000:04:00.0: firmware: requesting iwlwifi-4965-2.ucode Oct 15 21:06:47 usambara kernel: iwlagn 0000:04:00.0: loaded firmware version 228.61.2.24 Oct 15 21:06:48 usambara kernel: Registered led device: iwl-phy0::radio Oct 15 21:06:48 usambara kernel: Registered led device: iwl-phy0::assoc Oct 15 21:06:48 usambara kernel: Registered led device: iwl-phy0::RX Oct 15 21:06:48 usambara kernel: Registered led device: iwl-phy0::TX Oct 15 21:06:50 usambara kernel: wlan0: direct probe to AP 00:0b:6b:2c:2e:31 (try 1) Oct 15 21:06:50 usambara kernel: wlan0: direct probe responded Oct 15 21:06:50 usambara kernel: wlan0: authenticate with AP 00:0b:6b:2c:2e:31 (try 1) Oct 15 21:06:50 usambara kernel: wlan0: authenticated Oct 15 21:06:50 usambara kernel: wlan0: associate with AP 00:0b:6b:2c:2e:31 (try 1) Oct 15 21:06:50 usambara kernel: wlan0: RX AssocResp from 00:0b:6b:2c:2e:31 (capab=0x421 status=0 aid=11) Oct 15 21:06:50 usambara kernel: wlan0: associated Oct 15 21:06:51 usambara dhcpcd[3819]: wlan0: dhcpcd 4.0.15 starting Oct 15 21:06:51 usambara dhcpcd[3819]: wlan0: broadcasting for a lease Oct 15 21:06:51 usambara dhcpcd[3819]: wlan0: offered 10.129.99.202 from 10.129.99.193 Oct 15 21:07:03 usambara dhcpcd[3819]: wlan0: acknowledged 10.129.99.202 from 10.129.99.193 Oct 15 21:07:03 usambara dhcpcd[3819]: wlan0: checking 10.129.99.202 is available on attached networks Oct 15 21:07:08 usambara dhcpcd[3819]: wlan0: leased 10.129.99.202 for 300 seconds And here is a similar output from 2.6.34-gentoo-r11: 2.6.34-gentoo-r11 ================= Oct 15 21:19:22 usambara kernel: iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree:d Oct 15 21:19:22 usambara kernel: iwlagn: Copyright(c) 2003-2010 Intel Corporation Oct 15 21:19:22 usambara kernel: iwlagn 0000:04:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 Oct 15 21:19:22 usambara kernel: iwlagn 0000:04:00.0: setting latency timer to 64 Oct 15 21:19:22 usambara kernel: iwlagn 0000:04:00.0: Detected Intel Wireless WiFi Link 4965AGN REV=0x4 Oct 15 21:19:22 usambara kernel: sdhci-pci 0000:08:06.1: SDHCI controller found [1180:0822] (rev 19) Oct 15 21:19:22 usambara kernel: sdhci-pci 0000:08:06.1: PCI INT B -> GSI 23 (level, low) -> IRQ 23 Oct 15 21:19:22 usambara kernel: sdhci-pci 0000:08:06.1: Will use DMA mode even though HW doesn't fully claim to support it.

Just a note: I've tested the latest Sabayon Linux 5.3 (~amd64) live CD and wifi connection doesn't work either. But now I'm trying latest Ubuntu 10.10 (64b) and it is working!

You have misconfigured something in your kernel, the module works fine, I have used it with every version from .32 to .36 without a single problem. Please ensure your udev rules are correct.
# iwconfig wlan0 wlan0 no wireless extensions. That is expected. iwlagn uses nl80211 now. Use net-wireless/iw, or enable wireless extension compatibility in your kernel if you want to stay with wireless-tools. Also ensure that rfkill is set up properly.

I can find this lines in /etc/udev/rules.d/70-persistent-net.rules # PCI device 0x8086:0x4230 (iwlagn) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:13:e8:a5:6b:a3", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0" (In reply to comment #6) > # iwconfig wlan0 > wlan0 no wireless extensions. > That is expected. iwlagn uses nl80211 now. Use net-wireless/iw, or enable > wireless extension compatibility in your kernel if you want to stay with > wireless-tools. > Also ensure that rfkill is set up properly. Thanks for hint. There is no CONFIG_WIRELESS_EXT in my config file (not event commented lines), so I think it's not supported in new kernels. I can find CONFIG_WIRELESS_EXT in 2.6.32 config. I hope I'll find something how to set up the iwlagn driver, I can't find anything useful in Gentoo documentation.
Finally I've solved the problem. I've recompiled kernel with "cfg80211 wireless extensions compatibility" enabled and it started working.
