Slow download speed 5GhZ - RBcAPGi-5acD2nD

Hi All,

As reported in some other topics in this forum, I’m having some issues when it comes to download speeds at 5GHz with my Mikrotik. Strangely, the upload speeds are higher than the download’s. In fact, I’m getting about a third of the max download speed I should get, and I’ve got no idea of what is causing this.

There are no firewall rules, and no substantial interference with other local networks around.

I’m sharing my current wlan2 config. However, if you need further information to help me with this, please let me know.
