FTTH upgrade - getting my LAN multi gig ready (lemmy.world)

It was recently announced that FTTH will soon (finally) be available in my market. The provider coming to town offers rates up to 8g.

I'm upgrading from DSL at <100mbps - really exciting! However I will then face a bit of an issue.

I self host many services over my DSL, and use custom firmware on my router. My DSL modem is in a transparent bridging mode. I like the flexibility and customizability this setup provides.

The new service includes a WiFi 7 router, but that means I'll also potentially be subject to all the weird things providers like to do, like adding backdoors, opening shared WiFi networks, force deploying different firmware, etc. Plus I won't be running any kind of service on the router itself, which I do have today (transparent proxy etc). The router I have today is not going to enable me to touch the peak bandwidth available.

What're the best options to upgrade LAN components so that I can support multi gig internal networking speeds, ensure my self hosted services all function normally, and I take advantage of the bandwidth the ISP upgrade offers? In your personal opinion, is it worth it to invest in upgraded lan components?

Anyone have experience converting from 1G LAN to 2.5 or even 10?

Do I really need 8G FTTH, of course not, but if I ever wanted to get the max out of it, what does that take?

Just a couple thoughts (I have a mix of 2.5Gb and 10Gb):

  • Mikrotik switches are a nice alternative to Unifi. Much less lipstick on the UI but reliable and fairly priced.

  • If possible, you'll probably want to use your own router rather than the all-in-one provided by the ISP. In my case, the router provided to me (Eero brand) did not even have a port fast enough for my service, and would have been an instant bottleneck.

  • Options for 10Gb-capable PCIe adapters (what you might put in your server or desktops) are more limited (at least they were when I transitioned a couple of years ago). Intel-based network adapters seem to require less effort to get working (driver-wise) vs. some of the other 10Gb / SFP+ capable adapters.

Finally, you are correct: nobody needs an 8Gb internet connection. Aside from well-seeded torrent file transfers, you will never reach that limit (and probably still never). And, you'll need an adequate storage backend to write that fast.
