Question about this surge protector and internet speeds..

I would agree with that thinking

There are no ethernet sockets on that surge protector, so you will not be plugging any ethernet cord into it. It does have two coaxial cable connectors marked In and Out, and some telephone sockets marked In and Out and Out again. The intent, of course, is that any telephone connection and / or coaxial cable connection that MIGHT be coming from outside your house to your computer system should be connected through those so that any electrical surge they pick up outside the home can be grounded out.

The most likely way you might get internet service to your system is EITHER via telephone lines using a suitable modem OR via a coaxial cable service. Whichever you have, you would plug the supply cable into one of the In sockets and then continue on to your system. For all the phone-cable or coax-cable systems I have seen, they never deliver data faster than 100 Mb/s anyway, so there is no problem.

Now, we have a third kind of internet connection of a type becoming very popular. We got fibre-to-the-house that carries all our communications modes by optical fibre to a terminal in the basement. It can't get electrical surges. But more importantly, the terminal (powered by plugging into a house standard outlet) has its own electrical protection and provides as its output separate sockets for telephone and ethernet signals. So there is an ethernet cable from it to our first router in our home network. It happens that network is Gigabit ethernet, but we are only buying 75 Mb/s download service from the ISP, so even a 100 Mb/s limit would not be a problem. Still with that system we have no need or method to connect some surge protection to the ethernet cable from the optical fibre terminal.

Now, IF you are NOT using a phone line to bring the internet your computer, that leaves the phone sockets on the surge protector unused, as ours is. So what I'm doing is that the actual PHONE line to my computer (used for a FAX / Modem unit for FAXes) goes through that surge protector feature. On second thought, that last is no longer necessary because the phone lines in the house also come from the fibre system terminal box. I just never changed the connections at my computer when we upgraded from phone lines to optical.

It's confusing.
The picture of the surge bar shows the jacks labelled as Phone, but if you read the specs you see that there is an RJ45 (ethernet) along with phone. How they do it with 3 ports is beyond me, but he won't be using any of them anyways.

dudio is right - I missed that detail. It looks like both the In and first Out sockets are RJ45 ethernet sockets. I don't know if you could plug a RJ11 phone jack into one of those for phone line only use.

Anyway, OP, you got your system working with a slightly different unit, glad to hear. And it appears you somehow got a bonus on your speed. I don't know about how it goes where you are. In the past with our ISP, on at least two occasions they increased the speed of most customers that had only basic speeds on a DSL connection, for free. They were just keeping up with new offers by competitors and upgrading their equipment in the bargain. But now they are proceeding to go fibre-to-the-home to every home in this city, and marketing all types of communications through that single-connection system: phone, internet, TV, and security services, making it tougher on the coaxial cable competitors. And I can tell you, 75 Mb/s download sure is a LOT faster than the DSL system we had less than a decade ago.
