Hi, can I have the firmware version of your Deco M4/S4?

Do you set Deco into "Access Point mode"?

It is also suggested to set another Deco as the main Deco: How to replace the main Deco with another Deco.

 

As there are 5 Deco units, did the 4- 5 Mbps refer to the network speed of the main Deco or one of the satellite units?

By the way, can I have some pictures of your network map, such as:

Wait for your reply.

Best regards.

I bought the new mesh 7 system and have the same issue. Internet test on speed says 1500mb down load and almost 2000mb on the upload.Which is great but but the network freezes constantly. I am a family of 5 with 11 devices connected and I can't watch tv because it can't get enough bandwidth. No ones phones will load. Mine is all wifi setup as the Ethernet was slowing down the network. I even had my IT company from my business come out and they said its the network not the setup. JUNK!

Hi, may I know the model number of your WiFi 7 Deco?

Have you tried to set the IPV4 DNS to 8.8.8.8/8.8.4.4:

It would be highly appreciated if you could start a new thread here with more details, such as the network map on the Deco APP and some screenshots of the "Test Internet Speed" on the Deco App:

Thank you very much.

Best regards.
