I don't believe it's my internet connection because I'm on the same network now on my laptop.
When I ping my router in command promot "ping 192.168.1.1" I get a failure rate of 25% or 50% - when I ping google it's the same but sometimes 100%.
I checked the network cable and it's all good. I've unplugged them and plugged them in again to be sure. I've restarted the router as well. This is has happened before and it just comes right then fails again but is becoming more common.
Firstly how can I diagnose an issue?
If something is starting to fail in my PC what actually needs replacing? I'm connected via a Ethernet cable
