Thank you so much, TL MR3020 router I've run yesterday, then I have problems again .. I can not enter setup, because I have to change settings become wan lan, I have tried to install and unplug lan cable and power supply but still not managed to get openwrt. .
I have tried to ping the IP Address and successful but when I tried to get in openwrt, I could not connect, whether it is the effect of changes lan wan interface to that?
Can I restore into a lan wan interface?
I asked for help to change it, because I've tried all night to this day still does not successfully connect openwrt ..

I change the lan interface in this section

Set your computer's IP to 192.168.1.2, subnet 255.255.255.0
Connect the TL-MR3020 to your computer via ethernet
Power on the TL-MR3020
When the WPS button starts to blink:
on BB (Breaking Barrier / trunk) move the sliding switch quickly from one side to the other.
Do this until the WPS button starts blinking faster.
The device is now in Failsafe-Mode
You may access it by using telnet 192.168.1.1
Info on resetting to OpenWrt defaults can be found at: generic.failsafe

If still fail to login, then you need to use serial console.
You will need to make serial adapter using CA42 & open your TL-MR3020 then add some pin on P1.
