Your router is set to exchange keys every 10 minutes, I don't know why Airport reject to handle this, but I suggest to change the router setting since the keys exchange too frequently will reduce the experience of WiFi network.

[usr-sse2]

Strange, does it happen on 1.2.0 version? I tested key renew in those times and it worked.

[richibrics]

Thanks for the tip, I'm testing it now: received correctly 2 messages in 20 minutes. I'll update you later.

[richibrics]

@usr-sse2 I don't have any problem since yesterday when I downgraded AirportItlwm to 1.2.0; hope that it continues like that. Now the question is: what has changed to key renew in the latest versions ?

[zxystd]

@riccardo-briccola Hi, I am going to resolve the problem, but I can't reproduce that, can you help me to test?

[richibrics]

Sure I am available to test it

[zxystd]

Monterey.zip Big Sur.zip I upgrade firmware version to -68, can you see that if it would help?

[zxystd]

@riccardo-briccola Hello?

[richibrics]

Sorry problems with repo watch. I'll test it this afternoon thank you !

[richibrics]

Using it for an hour, seems okay; I'll continue testing it and keep writing you. Thank you

[zxystd]

well, are you using the same router? and can you give me the running log?

[richibrics]

Yes same router, this is the report. Sorry for the delay but I had problems with DebugEnhancer that now I've solved bugreport_6599.zip .

[zxystd]

@riccardo-briccola Thank you for the testing, so now I have push the changes to the repo, you can now use the latest alpha version to test, any issue please contact me.

[richibrics]

Fantastic, thank you for the help !

[richibrics]

After 27 days of daily use, it has always worked perfectly. Thanks again!

[zxystd]

Got it! Thank you for the help and confirmation.

[richibrics]

Works seamlessly since that update. Thank you !!!
