Satellite DECO X50V1 Disconnecting from LAN (Solutions)
Your main Deco unit is fine. You’ve got internet. But then the satellite X50V1 just drops from LAN. Random. Maybe once a day, maybe every few hours. Sometimes you catch it blinking yellow. Other times, it’s just not doing anything and your devices start lagging or jumping WiFi bands.
There are a few of the small checks, tips and solutions to solve this tiny technical issue “Satellite Deco X50V1 disconnecting from LAN”. Let’s dive in with the quick checks first.
Quick Checks
1. Ethernet Cable
Before diving into firmware, app settings, or prayers swap out that cable. I’ve seen a brand new Cat6 just randomly go bad and cause all sorts of flaky behavior. Use a known-good one. No fancy cable? Use your PS5 or Xbox LAN cable for 10 mins. Just test.
2. Port Check — Switch Port Shuffle
If you’re going through a switch between the main Deco and satellite, test without it. Plug the satellite directly into the router/main Deco and see if it behaves.
Managed switch? Disable any kind of loop detection, port security, or IGMP snooping temporarily. TP-Link units can get touchy.
Real Fixes — The Stuff That Actually Helped
Static IP Setup (Do This If It Keeps Dropping)
Go into the Deco app:
- Hit the “More” tab.
- Go to Advanced > Address Reservation.
- Add your Deco satellite’s MAC address and assign it a static IP.
This kills off those random IP lease drops that sometimes cause the LAN link to vanish. Especially helpful if you’ve got a DHCP conflict happening behind the scenes.
Turn Off Fast Roaming + Beamforming
In the Deco app:
- Settings > Advanced
- Disable Fast Roaming
- Disable Beamforming
I know, sounds counter-intuitive, but some Deco units especially when mixing models or firmware versions, start going with fast roaming on. It’s supposed to help, but sometimes it just breaks stuff.
Firmware Mismatch
Check both the main and satellite Decos for firmware updates.
- Open the Deco app or Deco login interface.
- Go to each unit
- Hit “Update”
If your main unit updated but the satellite didn’t, manually reboot the satellite, wait 2 mins, and then re-check. I’ve had the app skip updates and act like everything’s fine when it wasn’t.
Worst case — pull the satellite out of the mesh and re-add it clean.
Test in Wireless Mode First
Here’s a weird one:
Unplug the Ethernet from the satellite. Let it run purely wireless for a while.
If it stays connected longer than it does on LAN, something’s up with either the cable, port, or Ethernet backhaul itself. Could be interference or faulty wiring inside walls.
If it only crashes on wired, that’s a solid hint.
Bonus Tips (Learned the Hard Way)
- Avoid double NAT. If you’ve got Deco behind another router, things get weird fast. Run your Deco in Access Point mode or put your main router in bridge.
- Don’t mix and match Deco models if you can help it. The X50V1 doesn’t always play nice with older units like M4 or S4.
- If you’ve got a smart switch or VLAN setup, triple-check that the ports the Deco units use aren’t blocked or tagged weirdly. Decos are sensitive. Really sensitive.
Last Resort: Factory Reset & Rebuild
The reset process will wipe the device memory and bugs. It is easy to complete but then you will reconfigure the device from the Deco app or tplinkdeco.net interface. Let’s reset your device:
- Use the pin or pen and find the reset pinhole at the back of the device.
- Hold the button by the pin for 10 seconds and release it.
- After a few minutes the Satellite will reboots itself.
After that, you can reconfigure it through the computer or phone.
Reconfigure It through Deco Setup Page
- Connect a computer with the Deco satellite network via LAN or SSID.
- Go into the browser and search the URL tplinkdeco.net which will take you to the login page.
- Here, just enter the device admin default username and password and access the interface.
- Create the network and connect it to the host router by entering its network password key.
- After that, just finish the Deco Satellite X50V1 setup and connect to the extended network again.
The Conclusion
Hope, the “Satellite DECO X50V1 disconnecting from LAN” issue has been solved with the help of the above given quick checks, troubleshooting tips and solutions.
