@brokentpmesh,

This sounds like there may simply be an incorrect setting or configuration for your network that would be causing the disconnect.

But first, please make sure that your modem is able to receive the speeds that you pay for and is compatible with their technology. Simple mismatches such as Docsis 3.0v3.1 can cause intermittent disconnects like this.

What type of modem do you have and who is your ISP? If you have a modem that is capable of broadcasting a wireless signal, please make sure that the wireless and router functionalities are disabled.

Lastly, you can try to set up the Decos in AP mode, to see if this causes the intermittent disconnect issue.

So looking at our internal docs, we have seen a similar issue in the past for other devices; but none for the versions that you listed.

First Double Check that you're Deco is using the most up-to-date firmware as any fixes for similar situations have been patched through firmware updates. 

Otherwise, what is your ISP and Plan? Some ISPs and modems can cause intermittent interruptions when they send unusual internet traffic from the modem.

  @nightshade68,

Does the hardwired connection to the PC also drop when the issue occurs?

Another thing you may try to change is the Encrpytion Setting on Your network. I have seen, particularly with Smart Home Devices that they will intermittently disconnect from the network and not be able to reconnect when certain encryption methods are used.
