I have been using cAP ac for several years now. And since day one I have noticed that the 5 GHz upload speed is much slower than the download speed. I don't use 2.4 GHz at all so I haven't tested the difference between upload and download speeds with 2.4 GHz. And I use cAP ac only as 5 GHz wireless router, the ether2 port is disabled.
Below you can see the difference between download and upload speeds using 5 GHz. And to be absolutely clear, the ISP provides the same upload and download speeds, i.e. if I connect the computer directly to the WAN cable, the upload speed is almost identical to the download speed. Although it does not bother me much, I would like to understand why such a problem exists at all. I have reset the router to default settings several times over time, I have always used the latest version of the RouterOS, but it has never been clear to me whether this is the problem with RouterOS itself or configuration settings, or maybe my router has some hardware problems.
The router is currently running RouterOS v7.2.1 with this configuration, which is basically the default configuration -

Does anyone have any ideas that I could change in configuration to improve 5 GHz upload speed?
Thanks!
