Model: Deco X20  
Hardware Version:
Firmware Version: 1.5.0 Build 20210121 Rel. 54794

My network currently has 31 devices connected, all via DHCP. 42 DHCP leases have been given, and has always been working fine. All devices are working fine and are connected to the internet.

 

Problem: I built a new PC using a MSI B550M PRO-VDH WIFI motherboard which uses RealTek wifi & ethernet, and the wifi AND ethernet connection will not obtain an IP address via the Deco X20. Most of the time the ethernet connection in Windows 10 will show that it's an "Unidentified network", and will sit at the self-assigned 169 IP address. Ocassionally, seemingly at random, the router supplied by my ISP will assign an IP, and it'll start working. I do not want this, I want all clients managed by the Deco. This behavior happens for both the wifi and ethernet connections.


What's going on here? Why can't this client get on the Deco X20? There's no software installed on this machine except a few games, so no antivirus or VPN software.

Hi, may I know the model number of your main ISP-supplied modem router?

How about the wireless connection on the new PC? will it also get 169.254.x.x when trying to connect to Deco X20's WiFi?

I was wondering if we try to set up a static IP address on the PC which is within the IP range of Deco, such as 192.168.68.x. will it work with Deco when connected by Ethernet cable?

Wait for your reply.

Best regards.

  @David-TP Modem is a Arris NVG468MQ. I plan to set a static IP next time the issue shows up, right now it's operating on an IP from the modem without issue, but I would like it working via the Deco for the parental controls.

 

Is there a known issue with the Arris & Deco?

Hi, Thanks for the update.

Actually, It is the first time I got this feedback. So I don't think it is a known issue.

I will wait for your update and keep checking whether there will be similar feedback later.

Thank you very much.

Best regards.
