Hi,

since the last update to the latest SW I cannot connect to internet if I connect to the 5GHz WLAN (RT-AC88U).
On 2.4Ghz everything works fine.
Is there anything what I can check why only 5GHz has an issue?

So what exactly was the previous firmware version and what is it now? "Latest" isn't particularly helpful.

Is there anything what I can check why only 5GHz has an issue?
Look for errors in the router's System Log and Wireless Log.

Hi
Thanks for the reply.

Latest SW is the latest one which you can find is 386.2.4 and I had the previous release before which was 386.2.2.
It may also happen that in meantime I have set something wrong in the GUI accidently.
I guess I have to reset the router completely but redo all the setting again is a nightmare....
Save and restore all settings did not help.

The syslog does not show anything problem when I serach for 'error':

In the WLAN log I see also nothing strange:
