Could you please suggest or add a feature (in TPLink Deco X50 v1 Access Point mode) to more effectively block guest networks? The best solution would be VLAN tagging for the guest network.

My Network
I have created 3 VLANs in my home network.

VLAN1 Default - 192.168.0.x NoIsolate Proxmox
VLAN10 DOM 192.168.10.x NoIsolate - DECO | OMV
VLAN20 IOT 192.168.20.x Isolate - HomeAssistant
VLAN30 Monitoring 192.168.30.x Isolate

The main router is an ER605 + TL-SG1024DE Switch + 3x Deco X50 AP Mode

I wanted to achieve access from the main Wi-Fi network to all VLANs, while the guest network would only allow internet access.

I have several IOT devices connected to the guest network with the "Block access to local network" option enabled. They have addresses of 192.168.10.XXX.

When connecting to the guest network, I can't connect to OMV (in the same VLAN as the guest network), but I can access proxmox (VLAN1) and HomeAssistant (VLAN20).

I was considering buying EAP devices, but I don't have Ethernet cables running in the ceiling and the desktop devices are not aesthetically pleasing :( Deco X50 is more discreet.

It would be great to have all the new features also on X50 Pro version.

Hi everyone,

I installed the new 1.8.0 firmware on my Deco X50 V1. My setup consists of only two Deco X50 units, connected via Ethernet backhaul, no other devices, and I’m using Wi-Fi Router mode, not Access Point mode. Here’s my experience so far:

• Stability: Very stable, comes close to the reliability of 1.6.1.
• Network speed: Excellent, no issues observed.
• Traffic monitoring: Mostly works, but values are not always up-to-date and occasionally show incorrect data.
• App device view: The app generally shows connected devices accurately and which Deco they are connected to, similar to 1.6.1.
  • Exception: IoT devices sometimes do not reconnect properly after a restart, or show “unknown” as connection type.
  • In my case, these IoT devices include smart litter box, smoke detectors, Tuya smart plugs, Tuya smart lights, and similar devices.
•  
• Roaming & Fast Roaming: Works perfectly, for example with iPhones.
• Beamforming: Functions well.

Summary:

• Overall, 1.8.0 is very stable and fast, and the app device view is mostly accurate.
• Only IoT device handling after restarts needs some fine-tuning.
• Once that is improved, this version would be almost perfect.

Hi everyone,

after some more time testing the new 1.8.0 firmware on my Deco X50 V1, I’d like to share an update specifically focused on IoT network behavior — including some details that might be useful for others.

🧪 Setup:

• Two Deco X50 units with Ethernet backhaul
• Running Wi-Fi Router Mode, not AP mode
• A dedicated IoT Wi-Fi/secondary SSID separate from the main network

✔️ Positive results:

• System stability and performance remain strong — very close to firmware 1.6.1 in terms of reliability.
• Network speed is consistently good.
• Roaming and Fast Roaming work flawlessly (tested with iPhone devices).
• Beamforming also performs well and consistently.

⚠️ IoT-specific behaviour (new findings):

• After a reboot, some IoT devices do not reconnect properly — even when preferred connection priority is set to a specific Deco unit.
• Affected devices sometimes show as “unknown” connection type or attach to the wrong Deco.
• Devices affected on my side include: smart litter box, smart smoke detector, Tuya smart plugs, Tuya lamps, and similar IoT-type devices.

🔧 Temporary fix / Workaround:

Disabling the IoT network temporarily and enabling it again usually restores proper behavior — devices reconnect correctly and attach to the assigned node.

📌 Conclusion:

Firmware 1.8.0 is stable, fast, and overall reliable — especially compared to 1.6.1.

The only area that still needs refinement is IoT reconnection handling after reboots, particularly when using a dedicated IoT SSID. With some fine-tuning here, this release could become a near-perfect version for Deco X50 V1 users.

If anyone else is running a similar setup, I’d be very interested in hearing whether you’re seeing the same behavior or different results.
