Model: Deco X50  
Hardware Version:
Firmware Version: 1.2.10 Build 20241105 Rel. 40010

Hi,

 

Model: X50

Firmware: 1.2.10 Build 20241105 Rel. 40010

 

I have a Deco X50 home mesh running in AP mode and works fine currently. I am switching ISP and the new ISP send me a new router/modem.

 

I setup the new router/modem (without Internet yet) with the LAN running DHCP. The LAN subnet is the same as the old router.

 

When I move the connect from the main Deco to this new router/modem LAN port, the main Deco LED turn solid red. I can still see the SSID in my mobile but I just can't connect to it. I try rebooting the main Deco but still the same.

 

I also try reserving a static IP for the main Deco in the new router DHCP setting but still the same. Though I can ping the main Deco from the new router.

 

Did I miss anything here? Isn't it just a swing of the LAN cable will do the job? Appreciate for any comments.

Hi, welcome to the community.

Would there be any error messages on the mobile devices when they can't connect to Deco Wi-Fi?

 

Can the laptop still be able to access the web admin UI via the reserved IP address?

-If yes, it is recommended to manually install the 1.3.1 firmware here for Deco X50_V1.3_1.2.10 Build 20241105 Rel. 40010:

Deco X50/X55_V1.3_1.3.1 Introduced Channel Selection, WiFi Access Control and WireGuard VPN

 

By the way, may I know your new ISP and the model number of the new modem router?

Wait for your reply.

Best regards.

@David-TP

 

Thanks for the response. BTW, all my Deco is running in "AP mode" and "Smart DHCP" is turn off.

 

Once I swing the connection, the main Deco LED stay solid red. The satellite deco was red as well. I thought the satellite will stay green since it still has a connection to the main Deco. The main Deco stay red because the new router don't have an Internet connection yet.

 

All my wireless client drop off from the mesh SSID. I can see my SSID in my wireless client but just can't connect to it. The IPhone wifi status show a spinning wheel.

 

From a wired laptop, I still can ping the main Deco and able to access the web UI.

 

My new ISP is Optus and I was using a BYO router (Cisco ISR4k). GE0 (192.168.0.1) is my home network and GE1 is the ISP (FTTP) connection using IPoE.

 

Is the new 1.3.1 firmware a beta version?
