Model: Deco X60  
Hardware Version: V3
Firmware Version: 1.3.0 Build 20240830 Rel.50008

Hello,

I’m using Deco X60 (v3.20) with a 1000/50 Mbps fiber internet connection.

 

The problem is: no device in my home can get more than 700–750 Mbps over Wi-Fi, even when standing right next to the main Deco unit.

 

But when I connect directly through my ISP’s modem or use a wired Ethernet connection, I instantly get 900+ Mbps.

 

I’ve already enabled 160 MHz, selected a clean channel, disabled mesh backhaul – I tried everything.

 

Still, Deco’s Wi-Fi never reaches full gigabit speed.

 

Is this a limitation of the Deco X60? Or is there any solution or firmware fix?

 

Thanks in advance.

  @JamiryoFC How much linkspeed your devices are getting in the WiFi settings? Like im getting 433 Mbps linkspeed on my phone. If you are getting 866 Mbps linkspeed on your devices so your internet speed on WiFi can'nt reach to 1000 Mbps.

 

Please & Thank You !! ❤️

Hi, can I have the model numbers of the iPhone?

The following are Wi-Fi specification details for Apple devices:

https://support.apple.com/en-hk/guide/deployment/dep268652e6c/web

If your model is  iPhone 11 to iPhone 15 (except for the iPhone 15 Pro) and iPhone 16e

With the 1200mbps WiFi PHY rate, the expected network download speed would be 550-650mbps.

 

Thank you very much.

Best regards.

Hi, thank you very much for getting back to me.

If the smartphone is an iPhone 15, I think the current wireless speed is normal.

The maximum link speed of iPhone 15(2*2 Mu-MIMO) is AX1200 and doesn't support 160MHz, and Dec X60_V3.2 is AX5400 with 160MHz and 4*4 Mu-MIMO over 5GHz.

 

For the pre-set ISP profile, I can't explain why there isn't one for Türk Telekom.

If possible, you can start a new thread here with the ISP profile details, and I can forward it to the senior engineer for further evaluation.

Deco Feature Request

 

Best regards.
