One of my local ISP offers 10Gbps broadband for cheap. What is the cheapest router setup one can get with a 10Gpbs wan and lan port? WiFi and switching hardware is optional.
Do you want just 10Gb ports or do you also want 10Gb internet throughput?
cheapest option is probably a second hand office pc with a second hand 2-4 port 10gbit card in it
In the long run a PC will probably more expensive though, because it uses more electricity than a specialized embedded device. A specialized router is probably worth it if you stick with it for a while, at 10G there is little reason to upgrade.
Unless you go with a pc with 10gig interfaces my suggestion would be a mikrotik ccr2004-16g-2s and a couple of 10gig sfp+ interfaces. It comes with the added bonus of passive cooling and more software options than most of us knows what to do with. Even has WLC capabilities.
A UDM-pro might be a good option in addition to some of the other suggestions here.
Check out things like “Protectli Vault” and just put pfsense/opnsense on it
