    Does this ridiculous number of antennas even do anything or is it just marketing wank?

      Technically, it does provide better connection speeds by enabling the router to avoid channel hopping, so it can talk to multiple devices (or the same devices if it has multiple antennae) at the same time. This is part of the recent wifi6 and wifi7 standards so more and more devices will start to gain speeds using this technique

      Realistically computers have at best 2 antennae and this is largely marketing wank.

        Though if you have multiple devices all trying to connect to wifi, like even a phone for example, then a computer having two antenna that it can actually use 100% of the time still sounds valuable to me.

      I’m a network professional with a specialty in wireless.

      Yeah, beam forming and mimo are the main reasons for antenna diversity. There’s also more radio chains in those units typically, and more radio chains can provide better speeds if you have client devices that can take advantage of the extra radio chains (both sides need to have the same, increased number of radio chains to see an increase).

      The antennas are fairly small/thin pieces of wire that are not very long, so the antennas don’t need to look like that, but the quantity is useful.

        As someone with a telecommunications background who’s taken apart some cheap routers that look like that: the only caveat I’ll add is that the antennas are only useful if they’re actually connected to anything. From a decently trustworthy brand you’re probably fine, but I’ve seen a few where only one or two of the antenna couplings were connected to anything internally.

          There’s no shortage of liars and cheats everywhere. I’m unsurprised that a company world either intentionally, or through sheer ignorance, have “antennas” that are little more than aesthetic pieces of plastic.

      Some of them are marketing wank, some of them have MIMO channels that need multiple antennas to support independent bands with multiple devices.

      1 MIMO channel = 2 antennas, so this router could theoretically have 4 devices communicating bilaterally without interrupting each other.
