Plain Cat 5 still works fine at gigabit speeds. You might not get the whole 100 meter range, but you’ll get a useful fraction of it. It’s unlikely to be worth ripping out old Cat 5 cable unless you need multi-gigabit speeds (in which case, why no go to fiber?).
Can you provide the brand and model number of this white item? It’s hard to see in the picture.

It’s obviously a coax ↔ twisted pair bridge, but (I think?) our consensus in this thread is that you do not really need any non-gigabit coax, just go with twisted pair or (eventually?) fibre.
I didn’t find a link for that exact model, but I’ve found this:
Looks like a splitter to provide an ethernet and a TV signal. So, the ethernet outgoing port provides internet, and the coax output a TV signal (if you have booked that service from your provider).
Ah. It’s pretty much the same as this: Zyxel HLA3105 | ZyxelGuard.com.
That’s pretty much what I thought when I was saying “MoCA”. It’s a bridge from ethernet over coax to regular ethernet (and an output for old school coax TV too). Looks like quite an old device.
Well, it’s done. The tech replaced the ONT and ran an ethernet line upstairs. I no longer have the ridiculous setup; the router is now plugged directly into an ethernet jack.
I also want to say, kudos to Ziply Fibre.
Going back 15 years or more, we used to bounce back and forth every couple of years between Comcast and Frontier. We’d get sick of one company’s shit, and go back to the other. I don’t remember why, but six years ago Comcast pissed me off so bad I vowed “never again,” and we stuck with Frontier.
Anyway, every single time in the last 15 years we would switch, or move, or upgrade, or whatever, some issue would pop up where the company basically said “oops, we can’t finish this today. We’ll be back in two weeks. In the meantime, you’ll have no Internet. Sucks to be you. See ya!” Every. Single. Time.
So this morning I was bracing for the worst. But Ziply showed up, described exactly what they were going to do, and did it, all in about an hour and a half. And everything works!
I know it’s silly to get all gushy about a company actually doing what they said they would do. But what can I say… it’s a new experience for me.
