Description

My system is an HP Laptop EliteBook 2170P running OI hipster-20190308. The wireless device shows up this way in scanpci:

    pci bus 0x0003 cardnum 0x00 function 0x00: vendor 0x8086 device 0x088e
     Intel Corporation Centrino Advanced-N 6235

The laptop came with Windows 10 pre-installed. The wireless device works correctly under Windows.

In OI, the NWAM manager reports: Wireless Scanning for networks, but displays no wireless networks.

Just after boot, the following messages appear in /var/adm/messages:

My guess is that the wireless device is getting faulty firmware, or perhaps no firmware at all. The firmware files are present in /kernel/firmware/iwn . What's the solution?

I think this is a regression.

I can see this with

pci bus 0x0003 cardnum 0x00 function 0x00: vendor 0x8086 device 0x0085
 Intel Corporation Centrino Advanced-N 6205 [Taylor Peak]

which certainly used to work. Gary's and David's cards should work as well.

We need to find out, when it started failing.
