Model: Deco M4  
Hardware Version: V2
Firmware Version: 1.6.5 Build 20241231 Rel. 41802

I’m having an issue with my Deco M4R setup (2 units, hardware version v2.8, firmware 1.6.5 Build 20241231). I’ve set up both main and guest networks. The main network works perfectly fine across both Decos, which are connected via Ethernet backhaul through a switch. The problem is with the guest network — it only works near the main Deco. When I move to another room where the second Deco takes over, devices on the guest network either disconnect or show a “Failed to obtain IP address/ Could't get IP Address” error. The guest SSID is visible and devices try to connect, but there’s no IP lease or internet. This happens consistently. I’ve tried rebooting both Decos, resetting the second one, disabling fast roaming and Beamforming, but nothing changes. I feel like the guest network isn’t being properly extended by the second Deco. I’m pretty sure this isn’t just me — it feels like a bug that should be easy to replicate. Would really appreciate some insight or confirmation from others who’ve faced this. Thanks!

Hi, it seems like the reported issue is quite like the following post:

Reported Issue and Workaround: Guest Network works only on Main Deco

It is suggested to install the latest 1.7.0 version first.

Thank you very much.

Best regards.

Thank you so much for the quick response and for pointing me to that thread. I went ahead and updated both my Deco M4R units from firmware 1.6.5 to 1.7.0, and I’m happy to report that the issue is completely resolved- the guest network now works seamlessly on both main and satellite Decos, even with Ethernet backhaul.

Really appreciate your help! This seems like a common issue that a lot of users could run into, so I really hope this firmware gets an official release soon.
