Quoting: slaapliedjeI believe iperf3 requires a daemon on both sides, does it not? Been a while since I used it.

Just the iperf3 itself on both ends, yeah. So you can have two computers on the local network and check how fast data can be transferred between them. It's a good way to check if your cable is OK.

As long as your router, switches and network cards support 2Gbps.

I was actually thinking of making a custom router with some mini PC with 2.5 Gbps network card running openwrt or opnsense to replace my current WiFi router that's stuck with 1 Gbps.

Btw, instead of using Cat 6, there is an option to use fiber optic cables for your home LAN as well. You can connect SFP+ over USB 4 for instance.

I did buy a 2.5gbps switch, I haven't opened it yet. I'll test that out when I get home from the office.

Part of this weirdness I wonder if it may be due to where the data is downloaded from, not sure exactly how Steam works, but seems likely that something like Assassin's Creed would be hosted on Ubisoft's servers, whereas something like Elder Scrolls Online would be hosted on Microsoft/Bethesda's servers (With Steam it's kind of odd for MMOs, since some of them download via their launcher, which they all seem to have, and some download through Steam itself, like ESO does initially. Fantasy Grounds is a perfect example of this, the steam download is like 380MB, and then it downloads all the data from their servers.)

It was DNS... it's always DNS...

Apparently the Wifi DNS setting is 100% different than Ethernet! Which you know... makes sense :P

Oh? Did you have two DHCP servers?

I currently have a rather gnarly setup.

Basically in between ISPs, so I have Google Fiber on the one hand, and Centurylink on the other. My internal network is hooked up to CenturyLink at t he moment, and it is hosting dhcp, as well as I have a Synology NAS that I was playing around with setting up as an active directory replacement, and it needed to be configured to act as a name server for that to all work, so I had a static resolv.conf set up. Hence why it couldn't do name resolution correctly and it kept slowing everything to a crawl. Though you'd think once the name was resolved by hitting the one DNS server that it could reach, the speeds would be fine.

Ha, I definitely don't have what most people would consider a normal network set up.

Do you have 2 Gbps plan? I'm looking into setting up a 10 Gbps network at home and dealing with SFP+ is still rather obscure when it comes to common routers and switches. But on the other hand, it's way more affordable today than it used to be.

Learning about fiber optic options and SFP+ transceivers is fun too :)

I do! This is why I was trying to get 2.5gbps network started, as currently my devices all have 1gbps connections (except the one little AMD box I bought recently, but it's not connected near the router, which is the only place that I currently have any 2.5gbps connections).

I bought a 2.5gbps switch as well, but as my house currently only is using powerline ethernet, and I don't think they make faster versions of those, I'm kind of in a weird place where I have a fatter internet pipe than my internal network can handle....

Here are my findings so far (I didn't buy any of that yet, just researching). I decided not to waste effort on 2.5 Gbps and go 10 Gbps right away to avoid doing it again later even if ISP doesn't offer that yet.

Router: https://shop.opnsense.com/product/dec750-opnsense-desktop-security-appliance/ (bonus is it's running an open source router system - Opnsense).

Switch: https://www.amazon.com/MikroTik-CRS305-1G-4S-Gigabit-Ethernet-RouterOS/dp/B07LFKGP1L

Fiber optic transceivers

These have to work in pair for a multiplex set up using a single fiber optic cable. More common set ups are duplex using two cables (one in each direction). Multiplex is less common but doable, which allows using one cable in both directions where light travels at different wavelengths in each.

Transceiver for RJ45 connections: https://www.fs.com/products/74680.html

Adapter in case you don't have an extra PCIe port (because a lot of motherboards just don't give you enough if you have a GPU!):

This one connects to Thunderbolt / USB4.

The set up would be:

ONT <-> router <-> switch <-> rest of the devices.

I'd need to find something separate for WiFi to use as an access point connected to the switch.

If only you had mentioned some of this before…

Ha, well wasn't relevant to what I was seeing, as I had disconnected from my internal stuff as they were both using 192.168.1.x as the network, and I had forgotten about overriding DNS settings for testing AD.
