Problems with WiFi speed on Zyxel Multi X

Mervin

Last year I bought the Zyxel Multy X + Multy Mini. I have internet using a Experia V10 modem from my provider KPN. I have connected the Zyxel Multi X with a Cat8 cable to 1 of the LAN ports of the Experia. Speedtests result in an average speed of around 90 - 95 Mbps download and 123 Mbps upload when I connect a network cable to the Experia V10 or connect a network cable to the Zyxel Multi X. When I connect by WiFi to the Experia V10 speeds also range 90 - 95 Mbps. But when I connect by WiFi to my Zyxel Multy X speeds range from 8 - 12 Mbps download and 10 - 19 Mbps upload. 
What could be wrong?

I'm getting the same issue. I get up to 500mb with my provider Truespeed but when I cast my wifi through Multy x the speed goes down to 91mbps, upload 42mbps??? what's going wrong all of a sudden -- same wiring, same config etc...

Hi @Mervin, @Anthony_G

1.Please provide us the network topology.
2.How do you do the speedtest on the Multy X?
3.Could you provide us the Diagnose result on the Multy APP?

Best regards,
Jerry
