How to diagnose wlan card

B

balanga

I just got this weird error on my laptop which stopping my wlan from working.

I'm copying this msg on a different computer to make a note of it for further examination.
 
There's something definitely going wrong with my ThinkPad X1 (1st gen) with 13.2-R, at least the WLAN card.

Where should I look to identify this error (from dmesg)

Code:

Is there any way to diagnose this?

I seem to be having numerous problem with my wifi connection recently, and was wondering if there is any way to diagnose the problem, at least to see if it is a hardware problem, a driver problem, a configuration problem, or something running on the system which is impacting on the wifi connection. Here's a section from dmesg:-

Code: 
iwn0: iwn_intr: fatal firmware error

  rx ring: cur=26
iwn0: iwn_panicked: controller panicked, iv_state = 5; restarting

Any suggestions on where to look would be appreciated.

I'm running 13.2-R on a ThinkPad X Carbon (1st Gen)

Not familiar with gen 1, is the wireless chip on M.2?

I would exchange it for a modern card:

Can I tell exactly what card I have without opening up my X1?
