New Deco X55 pro's unstable connection
Model: Deco X55 pro
Hardware version: 1.6
Firmware: 1.1.1 Build 20230613
Hi all, I've been encountering issues with my new Deco X55 pro. Here's some background: I previously had the X60 set, which worked perfectly for me. However, I decided to return them and opt for a new X55 pro set due to the 2x2.5Gbps ports it offers. My ISP is CenturyLink. I set up the new Deco set by directly connecting the ONT Ethernet cable to the main Deco unit, and all satellite units were connected via Ethernet as well. Here's the setup diagram:
ONT cable > Main Deco > Switch > 2 satellite units
The problem I'm facing is that over the past three days since the setup, the Deco unit in my partner's office intermittently goes offline. Interestingly, even devices not connected to that specific node also lose connection during those times. The connection usually restores itself after around 5 minutes. I'm puzzled by the fact that my devices disconnected even when they connect to the node in my room, which has a separate Ethernet backhaul. Could this be due to a defective node or possibly a firmware issue? If I decide to downgrade the firmware, are there any additional steps required beyond manually downloading the firmware and installing it from the web UI page? Thanks all.
Here are the attempts I've made so far:
- I reset everything to factory settings and set it all up again this morning (though the issue reoccurred about 30 minutes ago).
- Swapped out the main unit with the other one in my room.
Updated: Right after I posted this, the same node has issue again, devices connected to that node dropping connection. The node's LED light is still green, I checked the Deco app and it still showing Ethernet connection between that node and the main one. All devices moved to the other 2 nodes. I sit next to the broken node and still not able to connect to it.
Here is the log line I see:
