Solution Reported Issue and Workaround: Guest Network works only on Main Deco
Previously Reported Models:
Deco E4,Deco M5,Deco M9 Plus,Deco X20, Deco X20-DSL,Deco X50-4G,Deco X50-5G,Deco XE75 and Deco BE63
Hi, Deco users,
It has come to our attention that randomly, users reported when satellite Deco units are hard-wired via Ethernet cables, no devices can connect to the Guest Network from the satellites and report an error "Couldn't get IP address". However, the same device connects well to the Guest Network of the main Deco, and after disconnecting the Ethernet cable from the satellite unit, the device can also connect to the satellite Guest network.
If you have experienced this anomaly, please feel free to leave a comment, including the model number and firmware version of your Deco.
Currently, some users have confirmed that restarting the ISP modem again after enabling the Guest Network resolves the reported issue.
In the meantime, the following firmware versions are also provided as a temporary workaround if restarting the modem didn't help:
| Deco M4_V1/V2 | 1.7.0_Official and above |
| Deco X20-DSL_V1 | 1.0.4_build_20220114_Beta |
| Deco X50-4G_V1 | 1.1.0_build_20230821_Beta |
| Deco X50-5G_V1 | 1.3.0_Official and above |
| Deco E4_V1/V2 | 1.7.0_Official and above |
| Deco M5 | 1.9.0_Build_20250911_Beta |
| Deco M9 Plus | 1.9.1_Build 20250909_Beta |
| Deco BE11000/BE63_V2 | 1.1.0_Official and above |

@David-TP
Have the same issue. My topology is as follows:
> X60
ISP Modem > BE85 > unmanaged switch > X20
> X20
Main network works flawlessly on all devices.
Guest network only works on main deco (BE85). Already tried reseting (and also turning off) ISP modem, but to no avail.
IoT Network seems to work on X20s but not on X60

Quick update. When skipping my switch and connecting the BE85 directly to the X60 through ethernet, it worked fine.
My switch is a "keepLink KP9000-9XH-X". It's unmanaged, so I can't configure the VLAN ID to match deco's, but according to documentation, it should just work.

Hi, thank you very much for your feedback.
Deco X60-V2.0-1.6.1 Build 20250912 Rel. 53642 doesn't support "IOT Network", so it will not broadcast the IOT SSID.
For the guest network issue, I'll follow up on your case and check with the senior engineer to see whether he had any other suggestions.
Please check whether you could receive my email later.
Best regards.

Experiencing this issue with main deco M9plus v2.2 on 1.9.1 build 20250612 rel 45960 and three satellites M9plus v1 on 1.7.1 build 20250905 rel. 58382.
I tried to install the firmware provided in this thread, the M9Plus_2.0_en_1.9.1 Build 20250909 Rel. 62888.
The upgrade goes through without errors, but the main deco fw will stay on rel 45960.

Hi, I think it might be due to the mixed Deco models in the same Mesh network.
It is suggested to temporarily power off the satellite Deco M9 Plus_V1_1.7.1 units, and leave the main Deco M9 Plus_V2.2 only.
Then log into the web UI again via 192.168.68.1 to see whether you can update the beta firmware this time.
Wait for your reply.
Best regards.
