Hi, thank you very much for the feedback.
Could you please help me check the following details as well:
1. May I know who is your internet service provider? And what is the internet connection type, like dynamic IP or PPPoE?
2. How much bandwidth you have subscribed from the provider and how much you could get now?
3. May I know how Deco units are linked together?

Hi,
I live in Italy and I own n. 4 Deco M4.
My internet provider guarantees me a 1Gb bandwidth and, if I connect directly to the modem (both in WiFi and in Eth), I can reach speeds of 940 Mbs; while, if I connect to my Deco M4 in WiFi (I use them in AP mode) I do not exceed 90 mbs.
Firmware Version: 1.5.2 Build 20210916 Rel. 56193
Please, how can I solve?
Thank you very much!

Hi, Thank you for reaching out to the forum.
I think your case is no longer related to the original post and could you please start a new post with the following information:
I think your current issue might be related to the WAN link speed of Deco.
Are you able to check the link speed of the port which is connected to the main Deco M4 from the ISP router, or do you have any wired laptop which could be connected to the main M4 and test the Ethernet speed of Deco?
Please also refer to the private message for more information.
Thank you very much.

I have a PC directly connected on M4 lan port and it works perfectly.
If I connect all my devices on M4 WiFi, they don't work: the speed is slow.
