Direct TV app

What model "Genie"?

Both your Genie and iPhone are connected to the same home network?

How is Genie connected to your home internet?

Is it home internet (DSL, Cable, Fiber) or something else (cell phone, hotspot, satellite, etc.)?

Note: It is DirecTV, not Direct TV (so single word, only a single T). Something to be cautious of with all the scams out there.

It’s connected wireless. I went under internet set up under settings, like customer service directed me to.  So both Genie and iPhone are connected to same ATT wireless. 

Umm "same ATT wireless"? That could mean WiFi to a router, wireless cell phone internet, hotspot, etc. Sorry but your info is rather vague. Please answer the questions with specific details so others can try and help.

Sorry I have a hard time explaining. I have ATT for internet service at home ( WIFI) so I used same network for DirecTV equipment and iPhone ( same passwords and everything) so same router. 

Ok, sounds like you have AT&T Internet (for home, not mobile). What is the name of your internet plan? (will help clarify which type of service it is).

What is the model of your Gateway? (that would be your modem/router combo unit)

What model is your Genie? You can find that usually on a label behind the access card door or if you go into settings and info and test it should be listed on screen.

What exact iPhone do you have? Was this obtained from AT&T or somewhere else?

Are the iPhone and Genie both connect to the Gateway directly, or do you have another router or some other device in-between?

Have you reset the Gateway itself or checked for any firmware updates?

Do other electronics have similar issues through the Gateway or is just your Genie and iPhone?

Just Genie and I phone no other devices. HR 54 and I phone 12

i was issued a new Genie and the same thing happens. I have multiple

times reset the Gateway. And literally all boxes multiple times.

Ok all 3 devices (Genie, iPhone, Gateway) have been reset and checked for updates are and are connected directly by wireless.

I would do a cache clear of the Genie (HR54), including refreshing the internet connection. This should be done in a specific order.

If resetting the Gateway was just by a button or setting through interface on the computer, unplug power for at least a minute and make sure fully back on before continuing.

Verify the Gateway is not set to hide the SSID (network name) as in my experience DirecTV equipment has not worked well with this hidden or using a WPS option.

On the HR54 go into Menu > Settings > Internet > Advance > Reset Network Defaults.

Unplug power from the HR54 for a minute. This dumps residual memory so hopefully clears anything it might have been holding onto that was causing a conflict. Be aware this does clear the guide data, so may take 24 hours or so for it to be fully downloaded from the satellites again. Also any Clients will be unavailable as they cannot work without the Genie, but any receivers will still function.

Once verified the HR54 is back up and running, then go through the internet setup. At this point it will be using completely fresh setting information instead of picking up anything it had cached before. Use the menu option in the HR54, not a WPS option.

As a note the built-in wireless connection of the Genies (since 2nd generation HR44), support both 2.4Ghz and 5Ghz. You might try both bands (if your Gateway supports them) to see if one gets it working but the other does not.

Try the DirecTV app one more time. Hopefully it connects at this point. If it doesn't then I can only surmise there is a software issue on one of the devices causing the conflict which will not straighten out until a later update. Good luck.
