I am not sure if there was a recent update, but I have 1G up/down from my ISP.   I was getting 700-900 both up and down, but the past month I have been having issues, and have it narrowed down to just wifi.  Devices that are plugged direct to the router get that 900+ down.  I have tried several patch cords, and have the main deco plugged into my router, and if I plug a device into the main Deco I am back to maybe 1M up.  It looked like all software is up to date, and if I connect to the WiFi on the ATT router, I also get 500+ meg, but use the deco. as it works in the whole house, but sadly when I use that I get that 1M upload issue.

Any help or ideas are appreciated, but parts of the house are now dead until this gets resolved.   Hardware version looks ilke 1.6

Thanks!
