I suggest switching the modem out of bridge mode, and setting the Deco in AP mode.

When you write "I go into the settings and it shows that I'm connected to my home network.", are you describing an anomaly, or do you mean everything was as usual?

  @yves_b 

Thanks for your reply. I am referring to the settings menu within the directv tream box. They allow you to change your home location 4 times a year. Even though it's not displaying my local channels because it must be thinking I moved the box to a new location, it still and has always said I'm connected to my home network.

I can do that and switch the decos into AP mode. I didn't do that from the start because I just figured it would be broadcasting an additional unnecessary wifi signal and may confuse devices and cause conslides?

Maybe I should set the modem back to gateway mode as you said but then don't broadcast the ssid from the modem/router and just broadcast the deco's ssid's?

  @Clent724 I expected that the wifi of the modem would remain disabled, independently of its mode of operation.

  @yves_b 

I'm no expert by any means so I'd like to clarify.

You're suggesting I turn the modem/router back into gateway mode. Then I turn off wifi broadcasting? So essentially the modem/router combo will still be the dhcp server and handout ip addresses even though wifi  broadcasting is disabled? Then the decos will operate as mesh and should resolve the issue?

Like I said, I'm not expert but have a general understanding of kinda how it works.

  @Clent724 I suggest turning back the modem into gateway mode, and disabling the wifi of the modem (assuming it is possible, as it is on many modems).  Broadcasting or not the name of the wifi SSID of the modem does not make a significant difference.

With the Deco in AP mode, the modem will indeed distribute the IP addresses, and the Deco will continue acting as a mesh.
I do not known if this will fix the issue.  This is an attempt to go back to the initial configuration, where everything was working well.

Once the Deco works in AP mode, you can as well connect the Genie box to the modem again, if it is connected by cable.

  @yves_b 

I will give that a try when I get home. I prefer not to have the gateway broadcast a wifi signal just because of unnecessary interference. I will attempt this and let you know how it goes. Thanks for the help!

  @yves_b 

I have one more question before I proceed to do as you said. Do you think this could possibly be happening because my modem in bridge mode has an ip of 192.168.100.1 and the deco was assigned automatically 192.168.68.1?

Is it worth trying to change the ip of the deco to 192.168.100.2 so it's in the same subnet?

Like I said, I'm no expert but this is just a thought.

  @Clent724 

I would certainly not assign to the modem an IP address in the local subnet of the Deco.

With the Deco in router mode, the Deco has two IP addresses, one on the "internet" side, one on the "local" side.

The "internet" IP address of the Deco is visible in the app, in More/Internet Connection.

Those two IP addresses are totally independent.

With the Deco in router mode, on the "internet" side, the Deco will only communicate with Internet, it should not communicate with the modem. 

The only way to communicate to the modem is by connecting a device to it, via cable or wifi.

It is certainly safer to avoid having on the Internet side a device with an address expected to be used on the "local" side.  We do not want to "surprise" the Deco.

With the Deco in AP mode, the Deco and all other devices will be part of the local subnet of the modem.

  @yves_b 

Okay. At this point I haven't changed anything yet. I reset the network from the deco app and then all the local channels on the DTV boxes started working. I then assigned the TV boxes designated IP's. I understand that's only within the network but I figured I'd give it a try. I'm going to not open the app again unless it messes up and then I'll switch everything into AP mode like you suggested. Most likely I'll be back here reporting that is what I ended up doing. 🤞 

  @yves_b 

So, it happened again. I finally had time to do the setup you suggested.

I am now using my cable company supplied modem/router combo (Technicolor CGA4234) with both 2.4 and 5ghz wifi radios disabled and then out of there the ethernet goes directly to the Main Deco P9 and I switched them to Access Point mode in the mobile app. So my modem/router is assigning IP addresses as it was when I originally got the DirecTV service but I'm technically connecting to that modem/router through the deco devices.

When I turned on my DirecTV stream box the local channels did not work at first. I went into settings of the stream device and set the home network to my current location. After that I restarted the box and my local channels were there again.

We'll see if this is a permanent solution but as of now it is working great. I'll know in a few days and will report back. Thanks
