A few days ago the internet went out.
It took AT&T 3 days to fix it, then when they replaced the router, the mesh system will not work.
I have been through the setup multiple times, it starts to work, then it says it cannot connect to the internet.
I have factory reset each node, still no joy.
Any ideas?
Anybody want to buy a set of barely used (less than 2 months) 6 nodes total?

Does the new modem take a while to boot up or longer than before? I ran into a issue with a velop system that it boots faster than the modem and would give me same error and pain to connect. You had to reset modem and give it a min or so head start basicly before trying to reset the mesh system. Also have you tried swaping to a diffrent main node? Or they may have given you a modem/wireless combo and the mesh system and it is fighting and one need to be setup in bridgemode.


Not a strong network guy so use this advise at your will lol.

I agree about checking whether the new modem is also a router. The D-Link will wanna do the routing too so one or the other needs to be in bridge mode. I assume you’ve verified that the new modem is actually connected to the internet and outputting data (either thru Ethernet or WiFi).

One other thing you might try is to delete the Deco app from your device and install it fresh. There might be something in the memory of the app causing the problem. How about using a different device to run the app.
 
Also, I believe the current version of the app is 1.10.7 (at least it is for iOS). You’ll wanna make sure that’s the one you install.
 
The new modem does take a while (usually 5 min or so) to boot up.

I tried everything I could think of.
I factory reset each of the 6 nodes.
I swapped out the main for another node.

everything works fine until the very end.
Also their customer service was unavailable
 
Is the new modem also a router?
 
Maybe?
I don’t really know.
I am not a tech guy.

it’s AT&T fixed wireless, so I have a router box thing that the internet comes from.
That is supposed to plug into the TP-Link mesh system via an Ethernet cable.

also, what is bridge mode, and how do I access it?
 
So, if the new modem is also a WiFi router (meaning your device can connect to it by WiFi even though the Deco isn’t working), then it is trying to do the routing (means sending the appropriate data to the appropriate devices) which the Deco wants to do also. You’ve gotta turn that off on either the ATT or Deco (although I’m not 100% sure that’ll cure the problem). To do it on the modem, you would need to surf to it using a browser. The address might be something like 192.168.0.1. If that works, you’ll see a dashboard for the modem and there would be an option to operate it in Bridge or Access Point mode. To do that in Deco, go to More, Advanced, Operating Mode. You’ll only wanna do it on one of the two devices. Can you post the brand and model number of the modem?
 
Wait, I just re-read your last post. You’re saying they replaced your modem but you have a separate “router box thing”?
 
I only have one box thing. it is the magic box that the internet comes from, so I guess its the router and modem.
The deco plugs into that via an ethernet cable

Perfect. So, if you can post the model number, we can find the address for you to surf into its dashboard.

Also, lots of them have the IP and login info on a label on the device- might be as simple as looking at the label on the bottom or back.
 
What bugs me is that this system was SO EASY to set up, and worked great. Then the modem goes out, and now I have spent 6-8 hours trying to fix it
 
Make sure your ip subnets aren't overlapping. If the dhcp addresses being given out by the modem/router are the same as the main unit then it wont work.

If your router/modem is giving out local IPs in for example 192.168.1.x/255.255.255.0 and the tplink main unit is giving out ips in the same subnet (that's it's default ip range according to their docs) it's not going to work right.

Change your router/modem to give out dhcp addresses in the 192.168.0.x/255.255.255.0 range and leave the tplink set to give out ips in the 192.168.1.x/255.255.255.0 for trusted devices and 192.168.2.0/255.255.255.0 if you have a guest network configured. At that point unplug power from the router, from the tp link devices, power up the router, wait a couple minutes, power up the main tp link device, wait a couple minutes and test connection to the internet. If everything looks good then plug up the rest of the tp link devices to power.

More than likely your old equipment was setup as a 192.168.0.x network and the new equipment is using a 192.168.1.x range.
