Is someone hacking my internet? Watch
However constantly my internet cuts off disconnecting the call and the light on my router flashes and it cuts off.
This obviously must happen for a reason so I am wondering, is someone hacking my internet?
The intention of someone to hack someone else's internet* would be to use it for themselves, not prevent it working.
*in the case of a personal home - a business would be different
Another point is that personal internet connections are extremely difficult to hack nowadays assuming you have WPA encryption (which is default).
More likely that your internet service is just crap.
