I have one RB 750, it was running ok no problem but after resetting it I can’t log in and even the Ethernet ports are not blinking(when connected with any PC or switch). I have reset it as it is said in the Routerboard website. The Ethernet port blinks for few seconds but after that no sign of activity. Any idea?

Nobody has any idea? BTW ethernet ports blinks for few seconds after resetting the board after that no activity and pc lan show only send bytes no received byte. anybody haven’t faced that kindda problem?

Have you nothing from light that burning?

Try netinstall procedure
Make sure that firewall is disabled on PC

connecting to 2-5 port are not different with connection to port 1. when the cable connected to each 8 port all leds keep off and no connection possible via software(winbox or web-base)

in netinstall procedure in fifth picture after drives there is a routerborad that i ask to select(named RB751G…) but when i try the same procedure my system can not find any routerborad in this (fifth picture) step!!!
