No wireless with an Intel3945 (Thinkpad T61, Slack 14.1)


Hello there!

I am having a problem with my wirless card with that computer. It is an Intel pro3945. It just won't connect!

The card is perfectly detected. I tried using Wicd and NetworkManager, and they both set the interface up, uthentificate, but when trying to ask for an IP they take forever before failing. No error message, just a cold, sad depressing "not connected" status. This ONLY happens in Slackware: I have tried Xubuntu, Arch and Gentoo, even NetBSD and freeBSD and the wireless works flawlessly under those. Slackwarewise I tried 14.1 stable and current, but nothing changes, always the "not connected status" and the laptop plugged to a tiny network cable to the router. Any ideas why is this happening?

Googling let me know that old versions of Slackware (11) had firmware for that, but the fact that we are talking over a decade old drivers, and that when you need firmware you don't have the card detected anyway made me think this is a no exit solution.

Thanks in advance!

During boot, do you get any messages about missing firmware?

My advice is to:
1. Uninstall wicd (NetworkManager is more capable)
2. Revert to a clean /etc/rc.d/rc.inet1.conf http://www.linuxquestions.org/questi...ml#post5496884
3. If you are still having problems, try setting NetworkManager to use dhclient in place of dhcpcd by replacing 'dhcp=dhcpcd' with 'dhcp=dhclient' in /etc/NetworkManager/NetworkManager.conf

From your description, I suspect a problem with obtaining an IP address via DHCP. This is usually caused by trying to use NetworkManager with a modified /etc/rc.d/rc.inet1.conf
NetworkManager expects that it will start the DHCP process. If there is an existing process, it causes a conflict.

Thank you for the replies!

I removed wicd, reverted to a clean inet1 (I actually never modified it, but made sure it was set up to loopback), I also tried changing the config for NetworkManager to use dhclient, but no avail. I can't really see the boot messages, but didn't seem to be lacking anything or giving errors.

Now that I think about it, after the fresh install I think wireless worked, and died after updating. I am going to format, reinstall and confirm this.

*no, reinstalling won't solve my problems. I must had been drunk to remember that.

I have a Thinkpad X61 with this card:
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

check lspci. Works for me.

you might wanna use
iwlist wlan0 scan
wpa_passphrase "ssid" password > wlan.conf
wpa_supplicant -Dwext -iwlan0 -c wlan.conf
dhcpcd wlan0

See if it works!

Well, I am writing from my old T61 and wireless!

Thank you slacktroll for the recommendation. I was about to do it, after rebooting (I was upgrading the system after the fresh install), and just in case I tried NetworkManager, and it worked this time!

I like to connect from the console too, but I am going to use this laptop at college, and I know they are different kind of networks, and a complete pain in the ass, with usernames and special logins, so I am happy to have NetworkManager (hope it works there).

I am not sure what I did different this time to make it work: I tried not less than 5 installations and countless of tinkering before to no avail.

I am using dhcpcd in networkmanager.conf
During install, I did choose "Loopback" as device for my network, leaving it blank (during other installs I used to just cancel network configuration, but it seems that changing it latter with netconfig was not enough).

I am very afraid of touching anything now :P But I am happy. Thank you everyone for the help!

NetworkManager has CLI - man nmcli or man nmtui - cannot remember from the top of my head, and I do not have an access to slackware machine at the moment.

Yes, nmtui. It is nearly as good as wicd-curses was (before a bug for last version makes wicd-curses to crash on console when you try to enter the options menu, not a Slack problem: Happened to me in Gentoo and Arch).

Sadly the version of NetworkManager in 14.1 is too old and doesn't have nmtui. It is available in -current tho.

nmcli is as complicated to use as using wpa_supplicant commands. That makes me to overlook it: If I need to memorize commands to use a WPA2 wifi, I am better off learning without the need of Networkmanager, so I could use it on different computers that might not have NetworkManager installed on them.

Ah, there I am again: Na´ve of me.

After playing a bit with Slack 14.1 and noticing that some of the programs where way too old and lacked vital functionality for me, I decided to jump to -current.... and the problem was back!

Nothing I did could solve it, up to when I got fed up and scavenged a spare Wireless card (this time it is an Intel Wifi Link 5100). It works now.... It is not pretty (this card is way shorter than the previous one, so the screws wouldn't fit, and I had to hold it with cello tape. I hope the keyboard puts enough pressure to prevent it from moving!).

I can safely say that Slackware somehow has a bug that prevents at least the 3845ABG from working. It can't be the Kernel's drivers, as the same 4.4.5 driver worked fine in Arch, I also doubt it is NetworkManager, as wicd does the same....

I don't know. I might try it one last time when 14.2 is out with the old card. It might be something exclusive for current
