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.
Exactly. A DIY router is fine, don’t DIY the AP.
You can absolutely “DIY” the AP. You just need the right hardware. Take something that has good wifi hardware and flash OpenWRT.
