22.7 and Amazon Alexa disconnects

[tre4bax]

Looking for some help into something that is driving me mad.

I updated my router about a week ago to 22.7.   Since then my Echo devices seem to be unable to maintain a connection.   They often say "something went wrong"  and they always keep breaking off when streaming. 

All my other wireless network devices seem to work at least as well if not better, though debugging wireless is not easy.  Has something changed that requires me to adjust something so that they maintain their connection?
