I found a TP-Link TL-MR6400 v7 and decided to play with it.
I followed v4 documentation and found out that I did not brick the device just yet. Firmware installed ok using tftp method, and luci responds to http.
The switch is a little bit mixed up, and the leds might need some improvements. Storage seems small, only 2 MB available to me, so not so much fun for apps.
LTE modem seems functional.
How can I contribute to get this device in better shape?
There is four lan ports in the switch, the last one is labeled lan/wan. When I select that port in the switch to be part of eth0.2, it becames the wan port.
Now, the wan interface selects a new random mac address every time, obviosly the hardware mac address cannot be found. I would like to get the same mac address every time from dhcp server upstream. What can be done to make the device fetch a static mac address from hardware?
