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.
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.
Do you want just 10Gb ports or do you also want 10Gb internet throughput?
