Delete the Deco network, and factory default every Deco unit. Once the network comes back up, connect only one device. If that is slow, power it down or disconnect and connect with your phone. 

 

Slowdown could be on the device being used or the Deco so use different devices to narrow it down.

• Copying files between computers is fast.
• Internet on each device is slow on both networks now, from the router to the clients but not from the router to the internet

 

If I factory reset as recommended, can I restore my previous settings using my login info, or will all those settings be lost? Renaming the devices on the network based on MAC address was a long, tedious process.

There is not a way to back up the configurations. You could look to do that as a last resort if you would like.

 

In the meantime, try swapping the main Deco unit with one of the satellite units.

 

Check the QoS speed setting, that may be set low so it would slow down everything connected. Manually set it higher.

I solved my problem. I couldn't afford the time wasted by resetting like you suggested. hopefully tp-link will come out with a backup settings feature which is a standard feature on almost all other routers on the market. What I did was I rename my SSID for the main Network. It ended in "-5g". I replaced this with another word and it works fine! So odd! It even works with a capital g "-5G". I went back to the lowercase and it broke again. So if anybody has an SSID that ends in -5g, and your internet is not working, give this a try
