[SOLVED] My Internet keeps disconnecting and comes back ?

[MyneRP]

As I said In the title My internet just cut off, It's not going off and have the yellow sign at the internet icon on the taskbar but it's literally just gone for a few second and comeback.
This usually happen when I playing games, downloading games and sometime just randomly happen when I was hanging out with my friend on discord and while working.
This's my result on ipconfig /all

Update your post to include full system hardware specs and OS information.

All network devices or just one particular computer? Check the LED's on the computer's Ethernet plug: colors, blinking, etc. Do the same on the router's LAN port(s).

Try another known working (no disconnection problems) Ethernet cable.

On the affected computer look in Reliability History and Event Viewer for error codes, etc. that correspond to the connectivity losses.

Make and model router or modem router? The router's logs (if available and enabled) may be capturing some error. Who has full admin rights to the router?

You will need help from that person.
