Not just noise..most modern routers allocate more bandwidth to 5ghz. So it is, in a literal sense, faster.

> allocate more bandwidth Do you mean the channel width? Quite possible, but whether that matters depends on whether your internet is faster than your wifi. If you mean allocating portions of your internet bandwidth, that shouldn't happen should it? Any connection method should have access to all of it.

  Not overcomplicating things intentionally. There's other reasons of course...standards, shorter wavelengths, etc. Not referring to priority(second point) but capacity. Tri band routers as I'm sure you're aware dedicate two radios to the 5ghz range, and one to 2.4ghz. If you have say, gigabit internet, your capable bandwidth on 5ghz will be much, much faster, regardless if there's any 2.4ghz interference. If anyone who isn't a radios expert cares... I prefer dongknows when reading about networks. A lot of people for some reason don't seem to like him, but he does a great job of both putting things simply, yet giving enough backing technical specs to not treat the reader like a child. example: https://dongknows.com/home-wi-fi-explained/ https://dongknows.com/home-wi-fi-explained/

Well, there's channel bonding, and wider channels, and a ton of stuff happening in the later standards (AX, 6) that I'm not up to date on, but... I'm pretty sure they get away with cramming more onto 5 largely because of the reduced noise.

  There is much more spectrum available in 5GHz and that's the overwhelming reason why it can be "faster". Doesn't go through stone walls though...

  If the broadband is the bottleneck then all that doesn’t matter one whit.
natch 5y ago
Not if the slow broadband is the bottleneck. It’s faster for accessing 192.168.0.1 and such but that’s about it.

  That's true, or in cases of in-network m2m communication of course. 5Ghz is still faster, you just can't utilize it if your internet speed is slow. It's like saying a Ferrari isn't faster than an old VW Beetle because the speed limit is only 25. Technically correct.

    If you want analogies, it’s the ISP provides a VW (connection speed), but it’s towing a Tesla Model S (which is way quicker than a Ferrari btw). Then someone comments about how the ISP is mixing and muddying the two, and some replies start going into all the technical details of how the Tesla is quick and why. Technically correct, but clueless because it’s the VW that is the problem.

      Fair rewording, but the point remains. 5Ghz is faster than 2.4Ghz. That a person can't take advantage of it because of their ISP is irrelevant to that statement. If the statement were, 'hey, if you want faster internet, use 5Ghz', well then it would only sometimes be true and such analogies apply. I can see where we're getting off track. Person A) ISPs are telling people use 5Ghz to get faster internet. Person B) 5Ghz is faster because 2.4Ghz is noisy. Person C) Well, 5Ghz is faster regardless of noise. Person D) Not if your internet is slow. So, seems we're all answering something else. I'm expanding on B alone, and you on A-C, I think.

        Yep, you got off track. B doesn’t matter in this picture. It’s 2.4GHz btw not 2.4Ghz, and it’s a range from 2.4 to 2.5 with 2.45GHz as the midpoint, and noise varies according to where in that range you are and what’s around. But again it doesn’t matter as it’s not the bottleneck here, so yeah, off track. Yawn.
