I purchased and installed a Deco E4R 3-pack to overcome a myraid of wireless network issues and enjoyed near flawless performance from them over the last 6 weeks - until the recent firmware update which has returned our network performance to pre-Deco performance levels. In short, I've so sorry I upgraded, I'm dealing with the same disconnects and poor wifi performance that I had before purchasing the Deco. I've tested the new firmware issues both as an Access Point (our original configuration) and as a Router and both seem to suffer from connection issues, especially if the wifi client is connect to a VPN (both MacBook and AmazonTV 4k FireSticks have severe wifi performance issues if they are connected to a VPN. The previous firmware had no such issues and worked very well as both a router and access point. Is it possible to downgrade to the previous version? Or is this a known issue with a beta firmware available to fix it?

Thank you,

Justin
