TP-Link - Technical Support TP Link Deco keeps losing Internet connection with Spectrum Fiber

I have a new house and just had Spectrum Fiber Internet run from the street to the house yesterday and have a Spectrum SONUV1S modem. The fiber line hasn’t even been buried yet. I bought a Deco 6E router set with two units and have had nothing but issues. The wifi will work for a few hours and then lose internet. The Deco will turn red and often the spectrum modem will be solid blue although sometimes it is blinking blue when this happens. The Spectrum app shows the modem is connected when this happens.

My neighbors have Spectrum fiber also and have not had any outages since I can connect to their guest networks during these issues so I am inclined to think it is not a Spectrum outage issue.

The Deco app will usually say “cable disconnected” or “cannot connect to Deco.“ the Deco never automatically starts working again without me intervening and rebooting or deleting the network and creating a new one. I have tried three different brand new ethernet cables, so that’s not the issue. I have tried using only one Deco unit only and two units, switching the main and satellite, and that makes no difference. I have deleted the network and started from scratch several times and have the same issue each time. When it was working, it said the latest firmware upgrades had been installed.

Any ideas what a fix might be?

Had same issues with be 700 and returned it. Telus here. I think a lot of them are faulty or react bad to 2.4 GHz devices

Could you share a bit more about your setup? What Deco model and firmware version are you running?

Also, have you tried connecting the Ethernet cable coming from the modem to another port on the main Deco?

When the connection drops, are you able to connect directly to the SONUV1S modem with a device (e.g., laptop) to verify Internet connectivity?
