17.01.4 on WRT1900AC with WMM Mode causing the router to restart by itself

Hey LEDE Forum collaborators,

After updating my Linksys WRT1900AC v1 to LEDE Reboot 17.01.4 r3560-79f57e422d / LuCI lede-17.01 branch (git-17.290.79498-d3f0685) and enabling WMM Mode (this improved my wi-fi speed on online tests from 20 to 250 mpbs), I noticed that my mobile devices are sometimes losing wi-fi connectivity for a couple of seconds or sometimes the whole router is restarting itself.

Any ideas on what may be causing this or suggestions on how to fix it? Enabling WMM was the alternative I found to improve my wireless speed, so I wanted to avoid deactivating it.

Thanks in advance!

That looks like a bug in the wifi drivers; I would first install these updated drivers:
Pre-compiled updated mwlwifi drivers for stable releases

If that does not fix the problem, I would open an issue at:

This is great! Thanks a lot!

Stupid question: are there any instructions on how to install it? I'm new to LEDE, so want to make sure I do that correctly.

When I look at the packages I have installed, here is what I see:


I guess I already have the most updated version? If not, how do I update it?

Thanks a lot!

No, that package is not the latest version. Instructions are at:

Thank you very much! Was able to download it, but getting an error when trying to export:

    Collected errors:
  • wfopen: kmod-mwlwifi_4. No such file or directory.
  • pkg_init_from_file: Failed to extract control file from kmod-mwlwifi_4.

Guess I need to know how to access the package after downloading it.

Any suggestions?


Not sure what wget done there, but the problem is the file is downloaded under the wrong name, "821c16ac-c2f2-11e7-94cb-8f52982d2ddd?X-Amz-Algorithm=AWS4-HMAC-SHA256"

rename that file to "kmod-mwlwifi_4.", then continue as instructed

Any suggestions on how to rename it? I'm just downloading the file using wget from @eduperez project in github, then running opkg install to install it.


Try with "wget -o kmod-mwlwifi_4. https://github.com/eduperez/mwlwifi_LEDE/releases/download/760f7bf/kmod-mwlwifi_4." so wget creates a file with the proper name.
