Hi,

I'm trying to get (1) to work on Debian Stretch.

>From what I understand, only "qca9982" v1 is supported on Debian,
however, (3) supports qca9882 v2.
That brings me to some questions:

- Am I on the right track by trying to build the firmware using
backports from (3)?
- Can I build the firmware in an VM an move that firmware to that
wireless box?

In other words, what should I do to get qca9882 v2 to work on Debian
Stretch?

Any help is appriciated.

2)  https://packages.debian.org/stretch/firmware-atheros
3)  https://wireless.wiki.kernel.org/en/users/drivers/ath10k

||According to specifications from Compex, WLE600VX utilizes
Qualcomm-Atheros QCA*98*82 chip.
I think it is a good idea to try packages from "stretch-backports" first
[1] [2], because it looks like WLE600VX was produced a few years ago and
should have already have support in linux kernel.
So I highly doubt this NIC model requires latest Qualcomm firmware
update, that was pushed into kernel.org source repository 9 days ago.

[1] $ rmadison -s stable,stretch-backports firmware-atheros
firmware-atheros | 20161130-4             | stable/non-free            | all
firmware-atheros | 20180825+dfsg-1~bpo9+1 | stretch-backports/non-free | all

Thank you, the last time I tryed didn't have much luck.
If I understand correctly, (1) does list the qca9882 v1 but not qca9882 v2?

1)  https://packages.debian.org/stretch-backports/firmware-atheros

I think "qca9882 v2" doesn't exist. What made you think there are different versions of qca9882 chipsets?
Support for qca9882 chipset was added to kernel 2 years ago and gets updated when new firmware version is available. [1]
This page from kernel.org wiki lists your NIC as supported [2], which means firmware file is available in repository.
At this moment "firmware-atheros" package from "stretch/non-free" repo contains firmware for qca9882 chipset, version 10.2.4.70.54 (ath10k/QCA988X/hw2.0/firmware-5.bin) which should provide support for WLE600VX NIC.
Try to get some information from kernel logs to see if ath10k module loads at all.
    # dmesg | grep ath10k
This guide should be helpful to debug more [3], especially these commands should output more debug information into kernel logs:
    # modprobe -r ath10k_core
    # modprobe ath10k_core debug_mask=0x00000432
