Do you mean the C3150 is connected to your main router, and has private IP on WAN? Do you mean V1 worked out-of-the-box before or V2? What's the current firmware version of your V2 router ?

Ha, it is also a possible way. Glad to know this.

Its maximum load it 16A on the universal website and 13A should be the required standard for UK market. If the kettle is not over 16A, it should be ok to use with the plug.

All modem routers are not affected. Check this link: http://www.tp-link.com/en/faq-1970.html
