hi. When ddwrt is installed on my comfast cf-e355ac v2 model device, the 5ghz section does not appear. Isn't 5ghz supported on this device by ddwrt?

Clear browser cache, CTRL + F5, or Shift+Command+R. Could also be that it requires activation:

Thanks for your answer. Activation was done and different versions were installed. but the result did not change. It works fine when I install stock firmware and openwrt.

System logs / serial logs would help determine the problem, possibly.

yeah logs would be good. in addition you have to consider that i never had a v2 in my hands. just a v1. so the port was made for a v1. for v2 i dont have any details about the hw. usually its very easy to port as it seems if just a card is not detected. but cannot say anything without some logs. according to my infos the v2 has just a wave2 chipset so its likelly it wont work since the wave 2 chipset firmware is not included. so this should be easy to fix

btw:

i included now the wave 2 firmware for this 355v2 into the firmware bin with some modifications (by guess). so i hope next firmware release will work (should be released today)

Thank you for your interest. I installed the firmware, but the wireless tab disappeared. I added the syslog logs of the wireless working version and the latest software that is not working.
thanks.

For what it's worth, on my R7800 I had problems with some of the December, 2023 builds where the 5G radio would not come up. I could see it in the UI, but it would not show up on any devices so I could not connect to it. However, those problems are gone as of the latest January 2024 build. (54682)

@UnicornStallion: The device was not officially supported until 54682. The log shows no wifi hardware initialized on the current release.

So it is supported now? As of 54682? All I am saying is that 5G in my Atheros based router worked, then broke, but works again with the latest January build.

When you go back to the previous version, the wireless tab comes back as 2.4g.
