ipw3945 alternative: Intel's iwlwifi

[d2_racing]

is it because i left mac801 or whatnot built-in, instead of as a module?

Plz read this thread : http://forums.gentoo.org/viewtopic-t-69 ... l3945.html

[d2_racing]

i tried the given ideas, and it said 'operation not supported', also only now i realize that when i do lspci, it says unknown device, on the network device part that should say intel 4965 or whatnot....

For you unknown hardware, you need to run this :

Code: Select all

# update-pciids 

[gforum]

i did what you said, fixed the kernel, loaded all 3 mods(iwl4965,mac80211,cfg80211) and! ...

well i get the result, ERROR interface wlan0 does not exist, or something like that... when wlan0 does exist.

also, i checked /etc/udev/rules.d/70-persistent-net.rules and it shows my wifi(iwl4965) and the interface as wlan0, so at least its not bogus.
though when i do ifconfig -a
i got eth0, lo, and a weird sit0, no idea what the bleep that is but...
and iwconfig shows, the above 3 and says no wireless extensions, etc... you know.

is this a /net config issue? a wpa one? i thought they where ok, i set them like you showed. lost here.

edit:also my wifi led was on, and now its not anymore... so maybe it really doesnt exist, even though if you go to /etc/init.d/ you'll find net.wlan0 there...

[d2_racing]

Ok, can you post this :

Code: Select all

# cd /etc/init.d
# ls -la

Also, can you post the result of theses command plz :

Code: Select all

# rmmod iwl4965
# modprobe iwl4965
# dmesg | tail
# ifconfig -a
# iwconfig

I need to see these results to help you

[gforum]

i coudnt copy/paste since i dont have x installed yet(no wifi), and i dont think chrooting would give accurate info.(am i wrong?)

but i think that the info you want is,
eht0>net.lo
wlan0>net.lo
iwconfig returns simply no wireless extensions for sit0, eth0 and lo.
ifconfig returns that eth0 is doing great, lo is what it is and that sit0 is ipv6-in-ipv4 or whatnot, no wmaster0 exists btw... shouldn't this be automatically created?

and finally dmesg reports the problem i think, it gives me some error, like error -12 or whatnot when trying to load the driver iwl4965 it says its a algorithm problem.

after all, this started after i set :
Code:

(*) Cryptographic algorithm manager
(M) SHA1 digest algorithm
(M) SHA256 digest algorithm
(M) ECB support
(M) CBC support
(M) PCBC support
(*) AES cipher algorithms
(*) AES cipher algorithms (i586)
(*) ARC4 cipher algorithm
(*) Michael MIC keyed digest algorithm

in the kernel, like it said in the post you linked...

the mod is working fine, loads and unloads...

if this info inst sufficient maybe you know how i cant copy-paste without X.

[d2_racing]

Hi, when you run ifconfig -a or iwconfig, do you see the interface wlan0 and wmaster0.

If not, you have a kernel problem.

[gforum]

then i got a kernel problem... but i just copied what the post you gave me said. which basically was, put nearly everything into M and some into *.

is that post valid for kernel 2.6.26?

[d2_racing]

Yes, but your need to enable the generic RFKillSwitch and the RFKillSwitch for the specific Iwl3945 driver.

I didn't test the kernel 2.6.26, but I know the man responsable of the Iwl3945 Intel projet and he told me that yesterday.

For the record, did you had IPW3945 driver before ?

[d2_racing]

The config that I posted is for the kernel 2.6.24 or 2.6.25.

[gforum]

(*) Cryptographic algorithm manager
(M) SHA1 digest algorithm
(M) SHA256 digest algorithm
(M) ECB support
(M) CBC support
(M) PCBC support
(*) AES cipher algorithms
(*) AES cipher algorithms (i586)
(*) ARC4 cipher algorithm
(*) Michael MIC keyed digest algorithm

dont recommend this to people...

basically i removed this and set it back to built in, and now everything is working fine.
thanks for the parts that helped D2!
(like wpa assistance).

[d2_racing]

No problem.

[kienjakenobi]

I just thought I might add that I am using the iwlwifi driver that is built into Gentoo-sources 2.6.25-r7 with my Intel 4965ABGN card on AMD64 with great success. I have been able to download things over my wireless connection at the same rates that I can when I am hard wired to the same connection. The connection automatically starts on boot with WPA encryption (Using wpa_supplicant) and I have not noticed it drop the connection once during my usage of Gentoo, despite an idle system for hours at a time.

[gforum]

did you set the mac80211 and cfg80211 as mods or as built-in?
or in general, what things did you leave as mod(regarding wifi ofcourse).

[breakerfall]

Hi, I'm having some trouble configuring my wifi...

I'm using the kernel driver, iwl3945 compiled as a module.

I'm running vanilla-sources 2.6.25.8

The module loads just fine, however, when trying to manually start net.wlan0, this is the output:

I'm have WPA2 "mixed" setup on the router.

Where am I going wrong? Is there a step-by-step guide to getting wifi on gentoo? Something that takes you from installing the kernel drivers, right the way through to configuring your setup to connect to different AP protocols (such as WPA2), all in one location?

Thanks

Hi, can you try that :

Code: Select all

# rmmod iwl3945
# modprobe iwl3945
# dmesg | tail

* Wireless radio has been killed for interface wlan0
* wpa_supplicant will launch, but not associate until
* wireles radio is re-enabled for interface wlan0

Are you sure that your switch is on physically on your laptop ?

Double check your switch on the side or the front of your laptop.

[d2_racing]

Are you sure that your wlan0 interface was up ?

Code: Select all

# ifconfig wlan0 up
# ifconfig -a

[gforum]

there is no central resource that i know of... but you will find some, at least half-baked ones, in the gentoo wiki.

maybe you need to add:

Code: Select all

modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dwext"

in the /etc/conf.d/net file... least to say of course.

also, i think that:
config_wlan0=("dhcp")
and, config_eth1=("dhcp")
are unnecessary since dhcp is standard ops.

and finally, read around the main wpa_supp. site and files, to see if the config you have matches what you need for your network. if you scroll a few posts back you'll see what i have, for instance. (just as an example -i use wep atm)
oh, and i would also, update my kernel. 2.6.26 is great. i love having my leds fully operational.

hope that helps.

The switch is definitely on. I can find other networks (my own doesn't broadcast the ssid), but I can't connect. I've run the same commands you've asked me to run here already, but here are the results:

Any other ideas?

Thanks!


PS

gforum, thanks for the information. I set dhcp manually so as to avoid the messages during bootup that state no config is defined, defaulting to dhcp. It would be great to have a central repository of wireless information for each card / chipset, from installing the drivers, right upto configuring the card with wpa_supplicant fully.

Hi there ! Well, your wireless driver seems to be working. I also get this ioctl warning and my network works anyway...

Can you manage to connect to any WEP access point ? Try to set up your AP in WEP temporarilly and try to connect to it You can use wpa_gui, scan and double-click on your AP (broadcast your ssid ), then set the key_tx0, just for this little test

Post the results here.

If it don't works, post the output of dmesg | tail after.

[d2_racing]

Also, are you using KDE ? If so, can you install wlassistant and check if you can connect to your router with this little program.

you need mac80211 and cfg80211 compiled as a MODULE, that should fix it for you.

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:18:de:77:91:fd", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

For the record the driver for your eth0 is that of an nVidia nForce. Do you have one on your computer?

BTW 70-persistent-net.rules is a file that is created automatically and maintained by UDEV. It holds the names of devices found on your system. So if you want to change the name of a device (say, an ethernet device) that's the right place .

If you want your Intel Ethernet (e100) to be eth0 then you can safely delete the lines that say

Code: Select all

# PCI device 0x10de:0x0269 (forcedeth)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:50:8d:b2:4e:4f", NAME="eth0"

and replace eth1 with eth0. Next time you reboot UDEV will append a line like the one you removed but with the nForce as eth1 this time. You'll also have to replace eth1 with eth0 in your network configuration file:

Code: Select all

config_eth1=("dhcp")
dhcpcd_eth0="-t 10" # 10 second timeout
dhcp_eth0="release nodns nontp nonis"
...

During bootup, when wlan0 starts during boot I get the ioctl[SIOCSIWAUTH]: Operation not permitted warning.

That is perfectly «normal» (in fact I have that too and it doesn't prevent association). The reason why your wireless card doesn't seem to associate is that an encryption driver probably lacks from your kernel configuration. See [post=5162369]gforum's post[/post] as to what drivers to include.

Ah, I'll try compiling them as modules too.

VinzC, thanks for the info - when I pasted the contents of that file (on request), I realised where I could change it.

The laptop doesn't have an nforce ethernet card, but my desktop does. I just recently (a few days ago) did a "stage 4" backup, tarring my root directory, bar a few that I wanted to exclude, then untarring that into a freshly formatted drive on my laptop.

It's a nice quick and easy way to get my desktop install, with configs I'm happy with and all my fave apps, over to my laptop with no compilation.

d2_racing, I'm not using KDE.


I'll post back with the results after I compile the stack as a module... thanks again.
