  @Joseph-TP Thanks! I answered the email

  @ojt1998 So sad to hear this 😭 I think it would be helpful if you create another ticket so it can be more visible for tech support. 

Hi  @ojt1998,

If you encounter a similar situation, please help us confirm the following information:
1. Provide more information about the phenomenon when the problem occurs, such as how often it restarts? Which LED lights are off when the network is disconnected?
2. Which client devices are working?
3. When did this problem occur? Has the router been modified recently?

With more details, we can locate the issue faster.

  @Joseph-TP 

Provide more information about the phenomenon when the problem occurs, such as how often it restarts?

Mine started rebooting constantly to the point the network was unusable

Which LED lights are off when the network is disconnected?

All Led's were going off as if the router was getting manually rebooted

2. Which client devices are working?

None as the router was fully rebooting

3. When did this problem occur? Has the router been modified recently?

it started the beginning of this week when my homepod and apple tv updated. No modifications have been made

  @Restarting will do

Just to mention my experience with these information

1. Provide more information about the phenomenon when the problem occurs, such as how often it restarts? Which LED lights are off when the network is disconnected?

It restarts after a couple of minutes. All the LEDS go off as part of the restart process and then turns on normally.

2. Which client devices are working?

When it restarts nothing works only works after all the lights have been up, but then it restastarts again 😭 

3. When did this problem occur? Has the router been modified recently?

From what I have read the problem started with the update of Apple TV OS 18.2 and when you setup the Apple TV to use as main audio output the Apple Homepods. I have another router, TP Link Archer C7, this problem does not occur.
