Dell Latitude 7450 Wireless PEAP
 

Hello,

I am trying to dual boot a linux environment on my Dell Latitude 7450 with a Intel Dual Band Wireless-AC 7265 network card. I have, so far, tried Fedora 22, CentOs 7, and Ubuntu 14.

The problem I am having is connecting to a 802.1x network at my office. We are using an AeroHive system for our wireless routers. They are configured to authenticate against Microsoft AD.

The wireless setup is PEAP, No cert required, and MSChap v2. I can connect to the wireless network perfectly with my Windows 7 dual boot of the machine. I can also connect to the wireless with a Android and iOS based phone. So I know the wireless works fine without it being a Windows based system.

When I try to connect via Linux I get one of 2 different error scenarios: 1) It just does nothing, no error or anything, just a timeout or 2) it repeatedly asks me for my credentials.

I am fairly new to linux and am trying to make Linux my main OS to use it everyday. In order for me to do that I need to get this one last piece working.

If anyone can shed some light on what might be going on I would greatly appreciate it.

Hi...

Welcome to the forum :)

I'd be curious to know if this problem spans all distributions but, at least for Ubuntu, I found these two threads here that might help...

Let us know how it goes. :)

So I put the system back to Fedora and tried to get it working again today and still no luck. I tried the options in those posts and no luck. I also noticed that I when I was connected to another WiFi at the office it was unstable. The 2nd network is our guest network which is just WPA2. The network would drop the connection multiple times.

When I used the laptop at my house which was a WPA2 network as well it worked very well. The home network is a 802.11G, at work I believe it was a 802.11N.

I copied a newer firmware to the /lib/firmware folder but the system did not use it.

Any other thoughts?

I tried the links and did not have any luck getting them to work. Here is some more information:

- I put the system back to Fedora to focus on getting it to work there,
- The laptop appears to work fine on my home guest network which is a 802.11G network.
- I could not get it to connect to the internal wireless network which is the PEAP network. The system kept asking for credentials.
- I tried to connect the laptop to the guest network at work, which I believe is 802.11N and it would not stay connected,
- I tried to update the IWL7265 firmware by copying the latest ones I found but the system would not load it.

Any other suggestions?

Could you open a terminal post the results of...

I'd like to see more information on your adapter.

Thanks!

Here are the results:

Hi...

Thank you for the output. From what I'm seeing online, the solutions tend to range from file editing to BIOS flashing (if a solution works at all) and, unfortunately, the more technical aspects are beyond my comprehension. :(

However, another thing you can try is mentioned here, if you haven't tried it already, which is to edit your "/etc/NetworkManager/system-connections/<ConnectionName>" file and change the entry in "phase2-auth" to "none." See the last posts on both threads. :)

If that doesn't work, you can see if the folks at "kernel.org" can give you a hand. I see here they helped a gentleman with the same or similar issue with a patch.

Another option is to upgrade to the latest stable kernel.

You could also try flashing your system's BIOS with the latest firmware, that fixed one person's problem, however, if you try this, be extremely careful!! This is an excellent way to end up with a very expensive paperweight if you use the wrong firmware! Make sure you get the correct file for your computer. ;)

Let us know how it goes, I hope you're able to get this resolved.

Let me ask you this, you mention edit the "/etc/NetworkManager/system-connections/<ConnectionName>".... I dont have a connection file... there is nothing in the system-connections folder. Is that normal?

I have been connecting to the Wifi through the Gui Wifi interface built into Fedora.

By upgrading to the latest kernal do you mean Fedora kernal? I believe I am at the latest there. If you mean upgrading to the latest iwl7265 firmware kernel I havent figured out how to get Fedora to load the latest one (it looks like I am 2 behind). I have copied them into the /lib/firmware folder with the rest of them but it doesnt choose it.

I'm not sure, it may be normal for Fedora. Just as some advice, you may want to be flexible with the distribution you choose. You may get this working on one other than Fedora. ;)

I'm not sure what to suggest here. You could ask around at Fedora's forum and see what file is the equivalent in this case. I have no idea. :(

If that's the case, please disregard.

No, I meant your computer's BIOS. If you don't know how to do this, don't touch it, let a technician (at a local computer repair shop, for example) do this. You'll be safer that way. ;)

Yep, I know how to update the firmware on the laptop itself. I am new to linux but not everything else :-).

Cool... :)
