Hi again, I wanted to add a few more technical details that might help identify the issue.

Router Model:
I’m using an Experia Box V10A (VRV9517).

What I’ve Found:
I managed to log into my router admin panel and checked the System Log. Every day between 03:00 and 04:00, there are logs showing that the router either restarts itself or temporarily loses the WAN link. This aligns exactly with when my internet disconnects daily. It usually comes back within 5 to 30 minutes, but it’s quite disruptive, especially for downloads or late work.

What I Tried So Far:

• Checked Time Settings and IPv6 settings. I disabled WAN IPv6 (it was already off), and also turned off ULA support.

• Looked for scheduled tasks or auto-reboot settings but didn’t find anything obvious in the interface.

• There are also frequent IPv6-related errors in the logs like:

  • radvd: problem checking all-routers membership on br0

  • sendmsg: Network is unreachable

• I’m not sure if this is causing the reboot or just another symptom.

Question: Is there a setting in this router that might be triggering an automatic reboot/reset every day?
If so, how can I disable or adjust this schedule?

Thanks again 

Update / Extra Info:
Just to explain my setup quickly:
Originally, the modem was in the living room, but after switching to fiber, it was moved to the entry of the house. From there, it connects to a SuperWifi point (the black round device), which is placed near my room.

I use a cable connection from my PC to this SuperWifi point — so even though it's wired on my side, it's technically running over Wi-Fi between the SuperWifi and the modem.

Now I'm wondering: could the SuperWifi be rebooting or losing signal around 3–4 AM? If that happens, I would lose internet on my PC even if the modem itself stays online.

Could that be what’s causing the daily disconnection?

Hello ​@xperson. Welcome to the KPN Community!

It's great to see that you've already done quite a bit of research into your connection and the issues. Of course, it's unfortunate that this is occurring, even if it's at night. You mentioned that you see in the logs of the V10a that the connection drops at night. I wouldn't expect the SuperWifi to be the cause of that. I would think that in such a case, you wouldn't notice anything remarkable in the logs.

Additionally, there isn't a setting in the V10a that you can change to schedule a reset at a particular time. What I always recommend in such cases, with an unstable connection, is to first give the fiber optic box and the Experia Box a reset.

Power Down the Fiber Optic Box (NT):

1. Locate the Fiber Optic Box (NT):
   Find the NT, which is usually a small box where the fiber optic cable enters your home.

2. Unplug the Power Cable:
   Carefully unplug the power cable from the NT. This will power down the device.

3. Wait for 30 Seconds:
   Leave the NT unplugged for at least 30 seconds. This allows the device to fully reset.

4. Reconnect the Power Cable:
   Plug the power cable back into the NT and ensure it is securely connected.

5. Wait for the NT to Reboot:
   Allow a few minutes for the NT to fully reboot and establish a connection.

Reset the Experia Box:

1. Locate the Reset Button:
   Find the reset button on your Experia Box. It's usually a small, recessed button on the back or bottom of the device.

2. Press and Hold the Reset Button:
   Using a paperclip or a similar pointed object, press and hold the reset button for about 15 seconds.

3. Release the Button:
   After holding the button, wait for the power light to turn red and release it. The Experia Box will start to reset.

4. Wait for the Reset Process:
   The Experia Box will take a few minutes to complete the reset process. The lights on the box will blink during this time.

Could you please try this first and let me know if it resolves the issue?

Alr, I have reset everything and it seems like problem is gone. I will update here or make new post once is comeing back incase its not fixed yet

I'm glad to read that the issue seems to have been resolved. Hopefully it stays that way and if not, we'll hear from you again.

Hello, sadly, the problem started to occur again. So what we did isnt solve the issue.

How unfortunate that the problems have starting to occur again. I think the solution to your problems is to contact our customer service. An agent can check your line and look for the solution. It might be needed to send you new equipment or to let a mechanic check your whole connection and fix the issues. 

Alright I will contact them

thanks
