Zurd:

Router: Linksys WRT3200ACM

LEDE: Powered by LuCI lede-17.01 branch (git-17.290.79498-d3f0685) / LEDE Reboot 17.01.4 r3560-79f57e422d

Kernel: 4.4.92

Forum thread: https://forum.openwrt.org/viewtopic.php?pid=369295#p369295

mwlwifi version: kmod-mwlwifi - 4.4.92+10.3.4.0.git-2017-06-06-1

Wireless radio0 is working perfectly fine but not on radio1 or radio2. There's random disconnection, can happen 3 times a day or once per 3 day. Only solution is to reboot the router. See the forum thread for more information.

hnyman:

Well, the current mwlwifi driver (with lots of fixes) should be backported to 17.01. The 10.3.4.0.git-2017-06-06-1 driver is ancient)

(I made a pull request about the 17.01 backport in October, but closed the PR at the end of November as it had not been accepted by then and additional fixes had been published in the mwlwifi repo. Hopefully somebody does the backport at some point.)

I found this information here about the mwlwifi driver:
https://wiki.openwrt.org/toh/linksys/wrt_ac_series#w8864_mwlwifi

Is this information current so that I can use this to update the driver?

Until it is backported to stable there is [[https://forum.lede-project.org/t/pre-compiled-updated-mwlwifi-drivers-for-stable-releases/3262|prebuilt]]

Zurd:

Would be very nice to have the latest mwlwifi driver in the latest LEDE version so nobody else can complain about this issue :)

I was able to update my driver with the code below. Now it's just a matter of waiting 3-4 days. If the Wifi doesn't disconnect, it means the problem has been solved with the new driver.

Copy the .ipk file link with the latest release @ https://github.com/eduperez/mwlwifi_LEDE/releases

wget http://github.com/eduperez/mwlwifi_LEDE/releases/download/af210f0/kmod-mwlwifi_4.4.92.10.3.4.0-20171129-af210f0-9321_arm_cortex-a9_vfpv3.ipk

scp kmod-mwlwifi_4.4.92.10.3.4.0-20171129-af210f0-9321_arm_cortex-a9_vfpv3.ipk

root@XXX.XXX.XXX.XXX:/tmp/

ssh root@XXX.XXX.XXX.XXX

opkg install /tmp/kmod-mwlwifi_4.4.92.10.3.4.0-20171129-af210f0-9321_arm_cortex-a9_vfpv3.ipk

New driver doesn't fix my problem. WiFI just got disconnected again.

Anything else I can try?

opkg list|grep wifi
kmod-mwifiex-sdio - 4.4.92+2017-01-31-3
kmod-mwlwifi - 4.4.92+10.3.4.0-20171129-af210f0-9321

Try turning off the third radio(see note in [[https://github.com/kaloz/mwlwifi/blob/master/README.md|readme]]), and mwlwifi [[https://github.com/kaloz/mwlwifi/issues|issues]]

Zurd:

I don't know how to remove phy2, but I have a feeling it's radio2.

I've done:
opkg remove kmod-mwifiex-sdio

opkg remove mwifiex-sdio-firmware
Now radio2 is kind of disabled, cannot use it anymore.

I now have 2 wifi on radio0 (nac) and 1 wifi on radio1 (bgn). Let's see if it's going to be more stable now. Thanks for the info!

Zurd:

I have an uptime of 10d now and the wifi never dropped, I even have 2 wifi on radio0 and 1 on radio1 for a total of 3 wifi network.

I can now confirm that by disabling radio2 (and probably updating to the latest mwlwifi driver) do fix the problem!

Your help was much appreciated, thanks!
