Check and, if necessary, configure the GL-MT3000 perfectly

Hi everyone,
ioP Thanks for adding me to the forum.
I am writing because I am trying to understand something.
I recently activated a 2.5 Gbps internet connection with my provider.
So far, everything is fine and I am not encountering any problems.
However, I have some doubts about the actual speed.
When I run a speed test with Wi-Fi, I noticed that I go beyond 400 Mbps, but I expected something more in terms of speed.
Is there any configuration I can do?
Thanks everyone,

@macuser79 welcome to the forum, I have a video for you from the YouTuber vantechcorner:

I believe your WiFi issues are a configuration issue, would you be able to confirm your WiFi settings?

thanks for the video..and that I had seen.
The problem is that by setting it in this way the speed was increased but not to reach the actual declared performance.
I still have to figure it out though

what client are you using for the tests?

If by client you mean the "computer", I'm using a Macbook Air M1 which should support WiFi 6 without any problems

Wi-Fi specifications for the following MacBook Air models are detailed in the table below.

MacBook Air (15-inch, M2, 2023)

MacBook Air (M2, 2022)

MacBook Air (M1, 2020)

802.11 standard, name, frequency

Maximum PHY data rate

Maximum channel bandwidth

Maximum MCS index

Maximum spatial streams / Type


1200 Mbps


11 (HE)



866 Mbps


9 (VHT)



300 Mbps


7 (HT)



195 Mbps


9 (HE)



144 Mbps


7 (HT)


Add in WiFi6 being a half duplex, and while your Macbook Air M1 will sync at 1.2Gbps 80MHz WiFi6, it's average throughput is around 600 Mbps.

What settings do you have on your WiFi, are you sharing the same SSID over both radios?

So if I understand correctly, my MacBook Air M1 supports the maximum speed of 1.2 Gigabit at a frequency of 80 Mhz.
However, I didn't understand what the "Maximum MCS index" parameter is for.
It shouldn't be the channel you rely on to get that speed.
Right ?
