Are gold plated splitters good for internet use?

I have been having issues with my internet for several weeks now. I called my ISP to send out a tech, when he looked at the splitter he immediately said that gold plated splitters are no good for internet use, it like sucks up the connection or deflects it or something like that. I am wondering if this is true? Unfortunately I will not know if the issue is fixed up till later in the evening, as that is when the internet disconnects, in the middle of my game playing time.
