I just started having this problem yesterday that my WiFi wont have internet, everything hard wired works perfectly but not on WiFi, I switched out my router to my older Linksys one and suddenly I have internet again, anyone having a similar issue?
This is to vague and doesn’t have any information to help troubleshoot. I doubt you’ll get more responses than this.
That being said, I have periodic connectivity issues that are resolved either by waiting for a bit or rebooting. Sometimes my 5ghz wifi will put itself into a non-valid 6ghz range, but correctable by re-assign a different channel.
I’m using OpenWRT Snapshot r28608 obtained from the openwrt firmware selector.
