Wifi 5G not working properly on Archer C60 v2

I'm new to OpenWrt, I'm trying to use it on an Archer C60 v2.

I installed the firmware, configured the interfaces, wifi and even load balancer MWAN3. Everything works fine except the 5G wifi.

I tried to change the country, channels, switching frequencies 20, 40 and 80MHz. Also tried to move around 18.06.1, 18.06.2 and 18.06.4 version. But without success.

It appears that the problem occurs more often when connecting 4 or more devices.

When I reboot the router the 5G works normally for a few minutes, and stops again.
It continues to appear in the list of wifi networks, but can not connect to it.

I picked up a C60 V2 today with the goal of setting it up for STA+AP mode (2.4GHz STA, 5GHz AP).

I've ran into what I believe is a similar issue. Once I connect 4 or more clients to the AP (3 Android devices, 2 PC laptops) the 5GHz appears to die in a few minutes. A reboot will resolve for a few minutes, but it always comes back.

Just ran though a full factory reset again and am keeping modifications to a minimum. Let me know if you found a resolution on this or not. Thanks!

It is written in your syslog what happens. Your client device makes several auths and assocs directly behind each other. Can u please provide a wireshsark dump? Maybe the association gets declined by the AP... If this happens, typically the AP gives you a status code why this is happening. And you can look them up in the 802.11 specification.

Hi @Sean, haven't found a solution yet, we are using only 2.4G for now :confused:

The difference I noticed is that you are using 'psk2' encryption and I 'psk-mixed'.

I will test this setting and come back with the result.

Hi @PolynomialDivision, I noticed that on Mac OSX after 5G died, Mac displays the window asking for password and reports that there was an authentication problem.

On other devices like Windows and Android, the password window does not appear, nothing happens.

I don't have much experience, but how would wireshark capture the logs if I can't connect to the network after 5G dies?

You have to set your wifi interface into monitor mode. Than you can capture a trace and provide a .pcap file, that I can observe. Which OS do u use? Do u have the ability to use Linux? On Linux u can very easily findout if your wifi card/driver supports monitor mode and set it with iw.

Note, that this trace may include sensitive data! Since you monitor all the network traffic.

Unless you have a very old device on the network, psk2 only would be preferred.

By the way I've had to reboot on average once a week. Sometimes it just dies on me and rebooting is easier than troubleshooting. My use case is unique as it's just a travel router to have a single AP that feeds into hotel wifi.

Unfortunately, setting just 'psk2' didn't solve the problem. Apparently it can take longer but it keeps falling and only the reboot can solve it. This makes it impossible to use 5G. :confused:

Hi @douglasjunior i have the same problem, c60 with mwan3 but i see that the problem start before i installed mwan3, so i think is a problem with de firmware version 18.06, you find any solution? thanks!!
