Intel WiMax and Wireless Problems, WiMax will not activate.

Postby tripflex on Mon Jul 02, 2012 6:54 pm

Alright i'm going to try and keep this as short and sweet as possible. Intel Centrino N + WiMax 6250 built into a Dell Latitude E6420, WiFi works, WiMax does not.

Originally I was able to see both wlan0 and wmx0 under rfkill list but even with attempting to rfkill just wlan0 itself and then bring up wmx0 did not work. I then tried rebuilding the modules using the latest compat-wireless, and then went further and used an even more newer version from http://git.kernel.org/?p=linux/kernel/g ... esting.git

So where i'm at now is i re-installed the entire compat-wireless set of drivers and it's now picking up the WiMax as a USB device and i'm no longer getting it showing up under rfkill list.

Linux bh 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Since it was showing up as USB i went ahead and built a VM using the same exact distro and kernel as the host and then attached it to the VM. This is the output i got from the syslog:

It looks like the WiMax is being recognized by the VM and loading the i2400m driver, but NM is showing "carrier is OFF" and just like when i first setup the laptop and the wmx0 was showing up on the host, NM puts the device under a "WIRED CONNECTION".

So needless to say i'm at the point now where the only thing left to do is bang my head against the wall. Does anybody have any suggestions or ideas on what I can do to try and get this thing working?

Either way all the threads i've found were people just having problems with WiFi which is not my issue and most of their problems were solved by installing the correct driver...which most didn't even know how to do. I've spent many hours trying to figure this out and just don't know where to go from here...

Thank you for contacting Intel Technical Support.

I understand that you have some questions in regards of Intel WiMAX* adapters and Linux*.

Note that at this moment Linux* is not a supported Operating System for the current line of Intel WiMAX* adapters.

Currently there are no plans to create Linux* support for the current line-up of Intel WiMAX* capable adapters.

We are sorry for the inconvenience.

Regards

Sergio G.

I got my Sprint WiMax Intel 6250 adapter to connect to the Sprint Network. Just wondering if you are or were trying to do the same. I can provide you the steps I went through to get it to work for me.
