TP-Link TL-MR6400 v5

Flashing via OEM web interface does not work.

→ docs:guide-user:installation:generic.flashing.tftp

You can flash via tftp recovery:

1. serve tftp-recovery image as tp_recovery.bin on 192.168.0.225/24
2. connect to any Ethernet port
3. power on the device while holding the reset button
4. wait at least 8 seconds before releasing reset button. After downloading the new firmware image, the power light should flash for about 3mins, then the device should reboot.

The standard configuration can be used, but DHCP (for IPv4) should be disabled, either in Luci or in the configuration file (/etc/config/network):

config interface 'wwan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option apn 'internet'
        option pdptype 'ip'
        option dhcp '0'

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

The backside is secured by just one screw, which is accessible by removing the right side of the label:

After having removed the screw, the panel is attached by plastic clips and can be pried open. See below for the position of the clips:

(Do this too often and/or apply too much force and these clips will break).
