  • 2x2 AC on 5ghz has an 867mbps max PHY throughput, which after a 50% derate for signal quality and overhead is still a very comfortable 400mbps… typical cable internet is around 100 to 500mbps with a lot of places offering “1gbps” that it never actually reaches, so it’s certainly sufficient for 90% of people.

    If you have a very heavy multi user (6+ devices always on) household you may find some benefit from an AX 2x2 or 3x3 router just because it can handle congestion better.

    It does. Wifi uses MIMO (Multi-in, multi-out) to run multiple concurrent data streams over the same channel width, which overcomes individual channel bandwidth limitations (there’s only so much radio frequency space to go around). Each stream having its own antenna, and having larger antennas, gives stronger signal/noise ratios, less retransmitted packets, and overall better connections.

    A lot of those high end “gaming” routers are often oversold though… MIMO improves throughput if you have an Internet link it can saturate; realistically even a midrange 2x2 802.11AC router will provide more wifi bandwidth than your internet does. And for gaming, they do nothing to improve latency no matter how many streams you run, as wifi’s inherent delay (5-15ms) is pretty much a fixed quantity due to its radio broadcast time-sharing nature. The meme is correct. A $6 ethernet cable beats any and all wifi routers and client adapters, and always will.
