Limited wireless speed on rt-ac87u

[jtm]

Hi all. I have the rt-ac87u with latest wrt-merlin. I am getting over 200 Mbps on Ethernet directly from router. However my WiFi is limited to around 90 Mbps on 5 GHz and 50 on 2.4 ghz . My guest login (2.4) is only getting about 25 Mbps. This holds across multiple devices. I have tried changing settings from default to the settings here https://www.rickygao.com.au/blog/tuning-the-asus-wireless-router-to-best-performance/

I have also tried tampering with each these settings individually and I can't get past these speed limits. This is frustrating as this router should be capable of faster speeds.

Is this type of wireless speed drop just normal?
If not how might I go about trouble shooting this?

Looking at your blog there's a obvious issue there, ASUSWRT supports VLAN.

About the specified issue, do you see it happening in all those FWs?

What is the link speed you get with the devices? Only 25 Mbps?

On my AC87U I get up to 886 Mbps links speed and full Internet speed (up to 150 Mbps) on wireless devices.

Indeed, what FW version was the test done?
