Internet disconnects at the router and only when I'm online

  • 772

My Internet occasionally drops out for my whole house when I'm on it, this doesn't happen when anyone else in my house is on the Internet, so this might be a problem with Ubuntu causing the Internet to drop out at the router? Any idea what this is?

I'm using Ubuntu 18.04 LTS on a ThinkPad T430 and the router is a DrayTek Vigor2760. The Internet provider is PlusNet and the house is in Buckinghamshire, UK.
