After a hardware upgrade I ended up with a spare mini pc. Noticed these two icons and thought I might be able to use it as a WiFi access point with VLANs using OPNsense.
Is that possible? If so, what do I even need to buy to plug into there?
I don’t need it to do any fancy dhcp, dns or firewall stuff, I just need a WiFi access point with support for VLANs.

You’d probably be a lot better off buying a decent access point (unifi, mikrotik, Aruba instanton).
Are any of those open source? I was hoping to go the open source route
Not really. If that’s a hard requirement, check out what is supported by openwrt or freshtomato.
There was a similar question a few days ago with some points about wifi adapters vs access points brought up.
It’s mostly just a strong preference, so if I can reasonably do it I’d like to. Some great info in that post, thanks for finding it!
You might want to check what the actual hardware is first. You’ll probably be fine, but client 802.11 hardware can sometimes be underwhelming for hosting because they don’t have good stuff like beefed up MuMIMO.
Although that’s assuming you will have a lot of traffic going through it, so you could always just test throughput and latency with iperf to see how well it functions.
I’d probably have to buy something before it supports WiFi. It’s built to run pfsense (has 4 ethernet ports) so I imagine that it would run just fine if I got it a good antenna, but who knows.
You should probably open it up and see if there’s even a Wi-Fi radio in there it’s probably not there because when they’re installed those plugs are removed and the screw terminals for the antenna are in their place
I’ve done this before on Ubuntu. You can install nftables for routing, then install hostapd for a wifi AP.
Sounds like a pain to configure compared to some of the more designated systems. Is the advantage that you use Ubuntu for other things as well, so it’s a more multifunctional system?
That’s basically it. My Ubuntu server is a router, NAS, plex server, public statum-1 NTP server, wordpress server, nextcloud server, security camera NVR, SMTP/IMAP mail server, CUPS print server, tor relay, and probably a few other things I forgot about.
You can do a lot with a single CPU from 2015.
I don’t have hostapd on it anymore. I now have dedicated APs on OpenWRT. The main problem with using a WNIC for an AP is that they don’t typically have a very strong broadcast output. I had to add an amplifier, and even then it wasn’t great.
Install fresh tomato to this and you’ll get a much better AP with very good firewall and QOS and traffic inspection. Also good SNMP for monitoring
I already have an opnsense router as firewall, so I don’t really need that part. Was just looking to add a WiFi access point.
Haven’t heard of freshtomato before but this seems like a nice option. I’ll look into it, thx for the suggestion!
