I have 2 m9 v1 decos and like many other have had a severely unstable network since upgrading to firmware version 1.51. I'm trying to downgrade to the previous version of the software using these instructions: https://www.tp-link.com/us/support/faq/2958/

However the unit does not seem to be going into recovery mode. I hold the reset button when plugging in and it will flash green for a moment then go to solid red. I have gotten it to consistently flash green once, but still could not connect. I also think the IP addresses used in the link above don't apply to the M9, as I found the only one that did seem to almost connect was http://192.168.68.1 

I was able to get the background of the welcome screen to load, but the interface just stalled at a spinning wheel for about 10 miutes before I gave up.

Any suggestions before I bin these things?
