Finally! Super cheap, super fast 5Gbps Ethernet adapters are flooding the market — but is it too little, too late for gigabit wired connectivity away from business use cases

RealTek unveiled a new range of RTL8126 5Gbps Ethernet PCIe and M.2 adapters back at Computex 2023 (yes, the year before last), promising extremely fast wired internet connections. 

Those adapters are finally now going on sale – and at pretty reasonable prices, too. The first module, available on Amazon for $27, is the 5,000Mbps Networking Card B+M Key to PCIe adapters, which works with Windows 7, Windows 8, Windows 10, and Windows 11.
