networking

For 2 gig internet you will likely need something more powerful, especially if you plan on doing much with your router (like using cake qos). The other challenge is finding a network card that works with 2.5 gb Ethernet. It is relatively easy to find a network card that works at 1G or 10G, but the 2.5G Ethernet cards tend to have issues (I have not personally had issues but forums are full of people having issues with the intel nic cards, even though intel networking cards tend to be recommended generally).

What I ended up getting ( don’t have 2.5G internet speeds, just wanted to mess around with it) was a n100 mini pc from Aliexpress. Serve the home has pretty good recommendations for hardware, and I followed their advice. They also had recommendations for switches that support 2.5G.

As a note, upgrading openwrt on a x86 systems such as a n100 mini pc can be annoying (but doable) especially when upgrading between major versions.

Also I highly recommend posting questions on the openwrt forums as the users there are super helpful, including to users asking questions about what hardware setups are good. It may be a good idea just to get some more perspectives/opinions. Link: https://forum.openwrt.org/
