What's the point of a dual band router when 5G will do for all?

    5G won't do for all, since there are still plenty of 2.4G devices with no 5G capability. Also, while 5G is faster, it doesn't have as much range as 2.4G. You are also able to separate traffic where you can place slower demanding devices on the 2.4G and high speed needing devices on 5G.

    Are talking about a 5G cellular network vs WiFi or are you talking about 2.4Ghz vs 5Ghz WiFi?  

    Those are two completely different things..... and 5G cellular isn't in market yet.

    Wi-Fi in the past cut your speed by half as it could only transmit in one direction at a time.

    Newer versions of it were backwardly compatible so if you had an old and slower network adapter in a device connected to your Wi-Fi then everything connected was slowed down to that slower speed.

    Now though there are "Wi-Fi Mesh" systems available that use both of the the legal unlicensed frequencies and all of their channels to provide a much better way of doing things at a price.

    Sometimes marketed as "Whole Home" systems by the way;

    Many older devices are not able to run on a 5G network. We have several at the medical practice that I do IT support for. They are older medical devices that still work fine and would cost hundreds of thousands of dollars to replace.

    Also having both 5G and 2.4G allows you to separate traffic. In our waiting areas, "patient" devices can get on the 2.4G radio. While "business" devices are on the 5G network. This separates them to reduce hacking and possibility that an infect patient device could attack our business network.

    Also, we have one device that puts out radio waves in the 5G range. No wifi devices will work on 5G in that area. They have to be 2.4G

    And it gives us more channels and less cross over between devices wanting to use the same channels. And 2.4G has a longer range then 5G, so it can reach devices that are a further distance from the access point.

    5Ghz has a much smaller range then 2.4Ghz. Highly doubt you'll ever see 2.4Ghz go away.

    Just to clarify, you're not talking about 5G mobile Internet, right? 5G is still in its early stages and not widespread. I live in a town about an hour away from Sac, CA where they supposedly have some 5G coverage, so I doubt we'll be seeing 5G here for a few years. And plus, existing devices won't support 5G unless they were designed for it specifically.

    If you're talking about a 5ghz Wi-Fi network, then there are still people who have legacy devices that do not support 5 GHz networks. My sister has an iPod touch 4 that only supports 2.4Ghz networks. Sometimes they don't want or can't upgrade to newer devices, so they still have to use older networks.

    There's a lot of devices that don't have 5ghz radios and still need the legacy 2.4ghz which has much greater range than 5ghz.    Many devices simply don't benefit from the speed anyway and it's much better to keep them on the 2.4ghz network as to not slow down devices on the 5ghz network that need the speed.

    5G is a completely different technology. It has nothing to do with wireless routers. Assuming you meant "5 GHz", 2.4 GHz has better range and penetration through walls.
