This is a basic feature that be550 (BE9300)  also supports.

It's just a firmware bug issue.

  @Sunshine 

is this hype?

  @kch140 It's a shame TP-link removed the 2.4GHz band from the ad, but forget to remove the word 'TRI band wifi 7' and number 9.2 GHz wifi 7 from it. Either way, I think it's a firmware bug. If it's not a bug, it's an outright lie to customers. The feature is even written on the box that the router came in.

Here's the current ad image

@Sunshine You just can't say 2.4GHz isn't supported when you advertised as it does. It's also written on the box!

I bought 2weeks ago mine BE550v1 and on the box shows that:

MLO in all tri-bands.

There is more false information. Also is a weaker signal then should be in all band.
i hope they do finally an optimalization of firmware soon as possible, and fix/optimize all problems.

Im sad i pay 300$ and advertising & specification don't meet with real product what we got :(

Seems all good reviews was paid... or some ppl just ignoring that how it working and they think should be like that lol.

  @Sunshine 

Can you comment or answer why on the box showing MLO works on all bands in BE550? :)
