After a home rewire, I’m ready to bump up to 2.5GbE, and demote my old 1Gbps router/wifi box to “AP Only mode”.

I want at least five six total ports, four of which need to be 2.5+ (three to different rooms, one for uplink, one 1G+ for the AP, and one “any speed is enough” for the networked printer :) )

It seems like the “mini-PC with a bunch of 2.5GbE ports running OPNSense” option fits neatly between “Build a router out of my old i5-2500K and some eBay NICs and ignore the USD450 electric bill”, and “enterprise rackmount gear with Delta fans left over from people overclocking their Socket A Athlons.”

I see a lot of machines of the form “fanless case with a little castle of fins on top, Intel N100 CPU, six 2.5G ports from I226 chipset”. A representative example is https://www.aliexpress.us/item/3256806214512701.html

I suspect they may all be re-brands of the same basic product, but I wanted to know real-world experiences:

• Basic question: can anyone vouch for any specific one of these devices/sellers and confirm it worked for them?

• I understand the i225-v LAN chipset was much buggier than the i226-v and to be avoided; still the case? I see a few products that are like USD50 cheaper, with different CPUs and i225-based LAN.

• For routing/firewall duties (probably 4 PCs, 3 phones, a couple printers, and some smart devices) , are the bottom-of-the-line configs (8GB RAM/128G disc) suitable? Is the CPU sufficient? The N100 makes me laugh-- Intel doesn’t even want to give it a brand name.

• Regarding WiFi, should I just block out that little Mini-PCIe slot on the board from my mind? I know that FreeBSD WiFi has been sort of a fourth-class citizen for years, but I was wondering if there had been a breakthrough, or at least a “here is one specific card you can buy for a largely drama-free experience”

• Weird question: Any problems with RF noise? I have had some devices where the power brick made a mess of a neighbour’s AM radio reception, and I don’t want to start a war with him. I figure when you’re buying a device with a 60w wall-wart from a random brand, it might not be the cleanest.
