I wanted to share this because I couldn't find a clear recovery procedure for the Tenda Mesh3 / MW6 V3.0.

I have two MW6 V3.0 nodes. After an automatic firmware update, both got stuck with a solid green LED and stopped working.

**Symptoms:**

* No Wi-Fi/SSID * Tenda WiFi app stuck on "Connecting…" * QR setup didn't work * No DHCP * RESET did nothing, even after holding it for 60+ seconds * Different power adapters didn't help

**Finding the recovery interface**

I connected my PC directly to the dedicated LAN port of the MW6. The WAN/LAN port was left disconnected.

I manually configured the PC Ethernet adapter as:

IP: 192.168.1.100 Subnet: 255.255.255.0 Gateway: blank DNS: blank 

The static IP is needed because the MW6 wasn't providing DHCP. Gateway and DNS can be left blank because this is a direct PC-to-MW6 connection.

Then I used CMD to scan the subnet:

for /L %i in (1,1,254) do u/ping -n 1 -w 50 192.168.1.%i >nul 

Then:

arp -a 

I found the MW6's MAC address responding at 192.168.1.6.

I opened:

http://192.168.1.6 

and found:

System Repair -> Emergency Web Server

with a file upload form.

**Firmware recovery**

My hardware:

Tenda Mesh3 / MW6 V3.0 FCC ID: V7TMESH3V3 

I uploaded:

[US\_MW6V3.0re\_V16.03.25.21\_multi\_TDE01.bin](https://www.tendacn.com/material/show/770177603014725)

The recovery page showed a countdown from 100 to 0 and "Updating File — Don't Power Down."

I left the MW6 powered on throughout the entire process.

After the update finished, the LED eventually became solid red. I waited several minutes, reconnected the PC to my normal network, and opened the Tenda WiFi app.

The node was automatically detected and connected again.

It is now running `V16.03.25.21 (335)` and working normally.

TL;DR:

If your Tenda MW6 V3.0 is stuck on solid green after a firmware update, don't throw it away yet.

1. Connect PC -> MW6 dedicated LAN port.
2. Set PC to:

​

 IP: 192.168.1.100 Subnet: 255.255.255.0 Gateway: blank DNS: blank 

1. Run:

​

for /L %i in (1,1,254) do u/ping -n 1 -w 50 192.168.1.%i >nul 

1. Then:

​

arp -a 

1. Look for the MW6's MAC address.
2. Open

​

http://192.168.1.6 

1. If you see "Emergency Web Server", upload the correct firmware for your exact hardware revision.
2. **DO NOT** power off the MW6 during the update.
3. Wait several minutes after the upload reaches 0.

This recovered my MW6 V3.0 after an automatic firmware update.
