    Intel PRO/Wireless 3945ABG

    Hello all,

    I'm having the following problem: I cannot connect to the wifi at work.
    Although network manager sees the wifi, when I choose to connect to it, it keeps asking for the password (and the password is correct).
    I deleted the wireless connection and restarted my pc, which allowed to connect for maybe 30 seconds and then it returned to its previous behavior.
    Other wireless connections seem to be working fine so I'm having trouble understanding the problem.
    The connection identifier has "apple" in its name. I don't know if that means that the router is made by apple or if this information is useful but I thought it might be.

    I'm running

    Re: Can't connect to wifi.

    Welcome to the forums !

    Please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

    This script makes no changes to the system. It just collects some useful info that helps us finding the problem and suggest a solution accordingly. The report it creates is stored in a file "wireless-info.txt" which you can examine yourself before uploading here. All the information that can potentially be sensitive is filtered by the script so the report is perfectly safe.

    Why are you using a non-stable kernel? Was there something that didn't work with the default one (or the latest stable - 3.12-rc4) and is working with this one?

    Your wireless card is an ancient model that uses a legacy driver, so I don't think anything is going to change with kernel versions.

    As a wild shot, you may try these when it fails to connect -
    Code:
    sudo modprobe -rv iwl3945
    sudo modprobe -v iwl3945 swcrypto=1
    If this doesn't help, try this -
    Code:
    sudo modprobe -rv iwl3945
    sudo modprobe -v iwlegacy bt_coex_active=N
    sudo modprobe -v iwl3945
    These changes are temporary and will be lost at reboot. If any of these seems to help, we can make it permanent. If none of these help, please download this alternate version of the wireless script : http://dl.dropbox.com/s/qjc87hzk1z5x6z0/wireless_script and run it when you are at work and the connection fails with the access point you were originally concerned about.

    Along with the script report, please also post the output of -
    Code:
    grep -R [[:alnum:]] /sys/module/iwl*/parameters

    Re: Intel PRO/Wireless 3945ABG

    I have an unstable version of the kernel because I was trying to fix my issue and one of the fixes I found online suggested a kernel problem.
    I'm going back to 3.12-rc4.

    I was looking at the manual pages for modprobe and it says that this command removes kernel modules. Why would removing the iwl3945 module fix the issue?

    Furthermore, what does swcrypto=1 do ? same for bt_coex_active=N? Why are you turning them on/off?

    Update: I can't seem to be able to go back to 3.12.0-031200rc4.201310080738

    You mean 3.11.4, you are already on 3.12-rc4 (yeah, I made the same mistake in my post too, looks like you copy pasted ). See here : https://www.kernel.org/

    I was looking at the manual pages for modprobe and it says that this command removes kernel modules. Why would removing the iwl3945 module fix the issue?

    Furthermore, what does swcrypto=1 do ? same for bt_coex_active=N? Why are you turning them on/off?
    Yeah, modprobe -r removes the module, then the second modprobe (without -r) loads it again, with the given parameters this time. In order to load with the parameters, it has to be removed first.

    The swcrypto=1 parameter enables software encryption, which means now the burden of packet encryption will be shifted from the card's hardware (hardware encryption) to the software (Software encryption, driver+OS). This helps when the hardware can't keep up with the speed of encryption required to keep the connection stable, sometimes not even good enough to establish the connection first.

    The bt_coex_active=N parameter disables bluetooth and wifi signal coexistence. A wide range of wifi frequencies are same as those of bluetooth which may cause mutual interference (when bluetooth is in use or is transmitting signals). To avoid that, the 'coexistence' technique is implied which is supposed to transmit/receive the signals in such a way so that they don't interfere. What is done to achieve this doesn't always work as expected. Sometimes the access-point may not like it, sometimes the driver or the device firmware may be buggy. And when that happens, disabling that 'feature' is the best and perhaps the only remedy.

    The firmware your card uses has been buggy since the beginning and Intel never cared to fix those bugs, perhaps they were more busy developing better cards. When this card works, it just works. When it starts acting, we can just try different things and hope they can make it happy again.

    Update: I can't seem to be able to go back to 3.12.0-031200rc4.201310080738
    You must have the older kernel still installed. Do you get the Grub menu at booting time? If not, press 'any' key during the purple splash screen to get the Grub boot menu, and choose the older kernel to boot from. If things work better or even the same way there, you may choose to purge the latest one.

    Re: Intel PRO/Wireless 3945ABG

    Hi Karol,

    Your wifi is currently physically turned off, most probably via the hardware switch (a dedicated switch or a Fn+key combination, whatever it is) -

    Please make sure the hardware switch is on first. Try the switch or the combination to toggle it on/off, then check with -
    Code:
    rfkill list
    Both hard and softblock should appear as "no". If not, try resetting your laptop's BIOS (if it is not a UEFI based system, which it doesn't seem to be, since the card is a real old one).

    Try this and post back the report. Once the wifi is enabled (hard/soft block is disabled), try to scan available networks and connect to them. If it fails to connect, post back a fresh report of the wireless_script.

    Re: Intel PRO/Wireless 3945ABG

    Hello i'm having the same issue; with repeating password requested.
    It works perfectly with a Ralink "big" dongle, if i disable the Intel in the bios.

    I would prefer the integrated solution.

    Here is the output of the script

    You may try both the parameters at once, and you should try that -
    Code:
    sudo modprobe -rv iwl3945
    sudo modprobe -v iwlegacy bt_coex_active=N
    sudo modprobe -v iwl3945 swcrypto=1
    ..and if it doesn't help, can you try changing the encryption type in the router for a test? Like WEP, WPA2 or no security at all? This would be just for a test and if it lets you connect, report back. Leave the changed encryption to WPA2 (with AES, not TKIP) if that is what lets you connect, or reset it to the current settings (WPA/TKIP) after the test.

    I trust you have already cross-checked that the security settings save in Network Manager are correct.

    Can you also try a newer version if downloading a whole new ISO is not a problem for you? Because as you can see in the report, you are still using kernel 3.2 series despite having upgraded to 12.4.4. We can manually upgrade your kernel and Xorg packages as mentioned here, but trying a newer version in a Live session would be much safer and easier, especially if the rest of your current installation has been properly setup to your liking and is behaving nicely.
