Hi there,

The internet through WiFi Ethernet speeds have dropped considerably after the firmware update, from 600+ mbps down to 7-30 mbps.

I was looking to downgrade the firmware to revert this, but there doesn't seem to be one available. 

From the looks of the actual hardware itself, it says v3.2, but on the Web UI, it says its just v3 which is a little confusing. Would they be interchangable? 

What it says I should be using -> https://www.tp-link.com/uk/support/download/deco-x60/v3.20/#Firmware

v3 has older firmware but I'm unsure whether I can use that or not. - https://www.tp-link.com/uk/support/download/deco-x60/v3/#Firmware

Things that I've tried:

- Disabling QoS

- Changing Ethernet

- Factory resetting modem (using virgin router) 

- Tested it out directly on another router and the speeds are completely fine without Deco. 

- This was tested on multiple devices through Iphone, macbook, windows PC, tablet, all giving consistent results. 

Any help will be appreciated.
