a tip for those that try to install openwrt for the first time
for me it didnt work to install via the web interface
it just didnt want to accept the bin file at all.
all this i did do with an ethernet cable.
download recovery bin file do a sfv check of it
set net interface to 192.168.0.5
start router in emergency up load mode
start router while holding reset for more than 6 seconds
connect to http://192.168.0.1 upload and reflash router
let it do its thing will take about 3 mins
set net interface to obtain ip automaticly
connect to http://192.168.1.1
continue the installation of openwrt
regards
