Internet disconnects when Desktop PC turns on

[Curious Adrian]

Just like the title, my PC seems to cut off my internet connection at home.

Now I have read a few similar threads about this but mine seems to be a different case.

Similar threads like mine mention about being disconnected from the internet with the LAN cable plugged in.

My case is different. When I turn on the system unit, it immediately cuts off the internet from my modem/router even when the LAN cables aren't connected and other devices connected to the network won't have internet access either.

My PC Specs:
Mobo: MSI H81m P33
CPU: Intel G3260
GPU: MSI GTX 1500 2GB
RAM: 4GB
PSU: 700 W
HDD: Seagate 1TB
OS: Windows 7


Modem/Router: ZTE ZXHN H108N

How are you connected to the router? Wirelessly or via the Ethernet port? Is your router pending any firmware updates? Is the router powered off the same outlet as your system? You might also want to see if the wiring in your house might be compromised. There are instances where there might be flux in your household to kill power to the router.

@Lutfij I have updated my question with the missing info that you suggested

I'm pretty sure that my router's got the latest firmware installed.
It's a desktop PC so it's connected through Ethernet port
Yes it is plugged on the same outlet.

Now my router does not power off when mynPC turns on, it's only the internet connected nnection
