HI @jay_s_uk , thanks for the reply
After installing just the Wifi update, Came up with the same scrolling error and then a message connected to the access point, IP address 255.255.255.255,
That was weird because that is a broadcast address. Anyway did the S0 and S1 again and it connected properly. Error is basically still happening.
I updated the DWC as a separate step to help anyone else troubleshoot,
First time I power cycled the printer, Came up perfectly, Connected properly and gave me the proper IP address.
Power cycled it again and back to the same error message.
However, If I just do nothing Eventually it does come online itself. Sometimes takes 2 mins to connect and give me the IP.
So I started thinking maybe there may be some other networks in the configuration that is toying with it. I ran the procedure listed in this Post
https://forum.duet3d.com/topic/9888/how-to-erase-remembered-networks/4
basically the M588 S"*"
I set up my network again from scratch with the M587 and now after 10 power cycles, It seems to be working ok.
If I was to guess what may be going on as you apply firmware versions it may be adding "default" or "beta" networks that it has to scan and see that they are not there before it will move on to the next one. That is strictly my guess but the version of the DWC definitely had the biggest effect.
For me, I just like to try and understand the source of the error but for anyone else troubleshooting this error take @jay_s_uk 's advice and ensure your firmware versions match.
