[SOLVED] Intel 3945ABG wireless wont connect Mint 14

Post by MrBrushTooth »

Been trying to get wireless to work on a laptop with Mint 14, but I havn't been able to figure it out. Found multiple reports of the same problem with this card, but none of the solutions that worked for them worked in my case.

Same issue as I read in other threads, detects the networks fine, but fails to connect after ~30 seconds.

Hi,
I searched for

Code: Select all

intel 3945ABG site:kernel.org
and found this link which might be useful
http://wireless.kernel.org/en/users/Drivers/iwlwifi
The simple solution when I look at that post would be to upgrade your kernel to 3.14.
I always use the procedure provided at Upubuntu.com http://www.upubuntu.com/2014/06/install ... 45-in.html.
I only did a brief search and read so my conclusion might be to fast.

One more thing: I would advise going to Mint 17 as Mint 14 has been out of support for more then a year now.
Or you might choose Mint 13.
Add (Solved) to the topic-title of the first post when appropriate so others know they might find a solution here.

No go I'm afraid!

Tried updating to kernel 3.14, tried Mint 13, and Mint 17 and I'm still not able to connect to a network.

Been fiddling with it for days now, searching for answers but I'm at a loss. Don't know if it's something I'm not seeing, or if it's just not possible on that laptop.


A real hair pulling pain that's for sure, I always have bad luck with laptops and linux, always one piece of hardware that wont work.

I'll keep at it a bit longer, and hopefully someone will be able to find a solultion, otherwise I'll have to throw windows back on it. :(

Re: Intel 3945ABG wireless wont connect Mint 14

Post by JeremyB »

Can you turn wifi router security off to see if it connects? Is DHCP enabled in network manager for IPV4, it might be called DHCP auto? Can you try different channels on your wifi router to see if one is better than the others? Possible to use just ABG on the router and not use N? You may have already tried these
MrBrushTooth

Re: Intel 3945ABG wireless wont connect Mint 14

Post by MrBrushTooth »

Tried no security + broadcast SSID but still no connection. DHCP is on auto, and I tried Mixed plus just B and G modes (I only have a B/G router).

I tried a few other channels, which gave me a few % difference in signal strength (75-90% range) but no connection.

Not sure if it could have any effect, but with you mentioning the router I thought I'd mention that my router is running tomato firmware (been using it for years any never had issues though).

Yeah, unfortunately and I also tried it with hw_scan=1 as some others said to try in other threads.

Are there any folders in /lib/firmware that start with iwl?
MrBrushTooth

Re: Intel 3945ABG wireless wont connect Mint 14

Post by MrBrushTooth »

No iwl folders in there that I can see.

There are iwl files though including one named iwlwifi-3945-2.ucode which going by the link Kalyk posted is the one that's needed if that's useful.

Unless Kalyk has any ideas, I would be buying a chip to replace the intel, something that works with iwlwifi module
MrBrushTooth

Re: Intel 3945ABG wireless wont connect Mint 14

Post by MrBrushTooth »

Yeah, I might have to. If it was for me, I'd just plug it in, but it's for someone who only has wifi access.

Judging by the number of results I've gotten while searching, it's a problem filled device but there were also a lot of people who seemed to have found some solution but none of them sadly worked for me, but I was hoping I'd missed something.

Thanks for your help regardless!

No problem, I would have suggested a RE2000 but you can likely buy 2 replacement wifi chips and still be portable

The conclusion uptill now doesn't feel right, so I search some more :?
Perhaps the Windows-drivers have to be used with the wrapper-stuff, but I have no experience with that.
You say you tried Mint 17, is that the version you are using now?
And which one, 32 or 64 bits, Mate or Cinnamon?
I hate to give up this easily (though I understand you have spent quite some time at it and perhaps so has JeremyB).

Re: Intel 3945ABG wireless wont connect Mint 14

Post by Kalyk »

I'm comparing your mintWifi.py-output with my laptop and observe some things.
Sorry if I repeat something that has been said already, I scanned through what was said before.

First: I see eth0 state is UP, does that mean there's a network cable in it?
Some computer have an option in the drivers or the bios to automatically disable wlan when wired lan is connected.

Second I see an IPv6-address in the ifconfig stuff, but no ip, but that might be because of not being connected, I don't know.

Have you looked if you have the latest bios-version of your laptop?

And did you look at the site of the manufacturer for hints?

Has the laptop ever been opened and is it possible that the internal antenna was forgotten to be reconnected?

O yeah, quite important, did wireless work under Windows?

I know, a lot of questions, but there are people that have it solved so it should be possible, shouldn't it?
Having a usbdongle in a laptop all the time is quite annoying.

Re: Intel 3945ABG wireless wont connect Mint 14

Post by MrBrushTooth »

Yeah, I should have mentioned I stuck with Mint 17 (32-bit Cinnamon).

The network cable was probably in when I ran mintwifi.py, but I've had it out when testing.

I'll have to check for a bios update, might help.

The wireless was working under windows, but it is an older laptop and that was 3 months ago (hard drive had died on it and I went right to linux with the new one) so it's always possible. I did have to install the new drive, but I'm pretty sure nothing was effected by it as it's just the one easy access panel.

I ran a script that runs a bunch of related commands that was posted on another site that someone put together for this kind of thing, maybe something in it sheds some light on the problem:

Re: Intel 3945ABG wireless wont connect Mint 14

Post by Kalyk »

Done some searching and I have two things.

The wlan is on channel 11. Some older routers go upto channel 9 I once heared. So look in your router which channels it uses.

And have you tried using wicd? Some wireless problems were resolved when using wicd.
Didn't look at the right way yet, something like disabling network manager and then enabling wicd.

O, and did you try the latest kernel in combination with Mint 17?
Add (Solved) to the topic-title of the first post when appropriate so others know they might find a solution here.

My router goes up to CH14, I had it set to 11 as it was the strongest, but have tried others to no avail.

I went and tried out wicd as you suggested and it hangs at 'Obtaining IP address' so I'm looking into that now.

As for the latest Kernel, no I forgot to re-do that when I installed Mint 17.

One thing I found when doing a search on the last line of you dmesg which was

Code: Select all

wlan0: deauthenticating from <MAC address removed> by local choice (reason=3)
led me to a post that said to try

Code: Select all

sudo modprobe -rv iwlegacy
and then

Code: Select all

sudo modprobe iwlegacy bt_coex_active=N 
I just had to edit the last code, been one of those days
