Hello,

Yesterday I flashed my new WT 1520 to openwrt.
I installed using this https://app.box.com/s/jyz599nk2rerma62p4zz

Everything worked fine and I could connect to internet just fine.

Today I try to connect via Wireless to my internet with the WAN port and I'm unable to connect there is no ip-v4 address and I can't connect to the web interface.
I can connect to the internet but I see a yellow triangle on the network..

However, when I put the internet cable directly to LAN then I can connect to internet just fine but then it's not connected via the WT1520 router..
I tried to reset but the reset button doesn't seem to be working..

what can I do please help!

with the serial console using Putty (speed=57600) you can enter into the failsafe and run firstboot command to erase all your changes, or mount_root and edit broken config files.
Also you can reflash it with tftp using the "2" u-boot option (you need to setup a tftp server with proper firmware)

Will it work?

The discussion might have continued from here.
