Your router has a different architecture, I do not think these packages are compatible. Does your device use the same packages? You can execute opkg list-installed | fgrep mwlwifi and post the results here.

Huh, you're right; it has mwl8k-firmware - 2017-09-06-a61ac5cf-1. Either the toh/techdata page is wrong, or its reference to mwlwifi doesn't mean what I thought it meant. 
I think the techdata page is wrong, the mwlwifi drivers do not support your hardware.

Packages updated to commit 7537480:
- Upgrade 88W8997 firmware to 8.4.0.46.
- Added code to load power table for 88W8997.
- Fixed the code to load calibration data.
- Change driver version to 10.3.8.0-20180810.
At first sight, these changes seem to be related exclusively to the 88W8997 chip, that is not present on any device supported by OpenWrt; I would not expect any improvements.
Packages for 17.01.5 and 18.06.0 available at https://github.com/eduperez/mwlwifi_LEDE/releases/tag/7537480.

Hi @eduperez 
First of all, thank for your work.
I've a question.
I'm in France, with a WRT3200ACM device.
When I'm on the 5GHz Wi-Fi, on the channel 100, it's happened than the router change the channel to the lower, 36.
I need to reboot the router to fix this issue.
I think it's the DFS.
You think it's normal?

Yes, that looks like normal DFS behaviour; have a look at the "Note for DFS of WRT3200ACM (88W8964)" message on https://github.com/kaloz/mwlwifi/blob/master/README.md, or review the explanation at https://pages.corifeus.com/github/lede-insomnia/docs/linksys-wrt-radar-detection.html.
Thanks.
I deleted phy2. I hope that the concern will be solved.
Doesn't work. My Wi-Fi is still on channel 36.
Have you read about DFS? As suggested, this sounds like normal behaviour dependent on location.
Yes, but it's annoying. : /
I can't reply to @lantis1008, so I do it here :
I don't know why I can't stay on channel 100, because I'm alone on this channel.
While on channel 36, there is 3 other SSID...
I don't understand.
Iām sorry that you find compliance with regulations annoying lol
@eduperez I didn't follow conversation between you and jow long enough, hence the question: does the 18.06.1 already include the latest driver/firmware for WRT3200ACM and you have no newer version to build or is the one coming soon?
18.06.01 contains driver version 10.3.8.0-20180615, which is not the very latest.
As if newer is automatically better...

I am trying to install the latest drivers for the WRT3200ACM. I have downloaded all ipks from your Github.
Currently I am getting the following:
root@OpenWRT3200ACM:~# opkg install --force-downgrade kmod-mwlwifi_4.4.140+10.3.
8.0-20180810-7537480-9326_arm_cortex-a9_vfpv3.ipk
Downgrading kmod-mwlwifi on root from 4.14.54+2018-03-30-fcaea79a-1 to 4.4.140+10.3.8.0-20180810-7537480-9326...
Collected errors:
* satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-mwlwifi:
* kernel (= 4.4.140-1-78acdb0e5133ba67c91f7694e305d1e7) *
* opkg_install_cmd: Cannot install package kmod-mwlwifi.
Thank you for your help and guidance...
Sorry I just read that you would test this this weekend. I guess the drivers I downloaded you released 2 days ago.
Are you installing these on the official build of 17.01.5? Make sure to carefully read which ipk is for which system.
Yeah I figured that out hours later. I am currently running this setup.
