I have RB751U-2HnD, just purchase few week, when I switch off the router than on back, the router cannot use. The LED only ethernet port 1 only light up (wifi and ethe 2(I connect to my desktop) not lightup) and I cannot connect to winbox.
I need to press reset button on router than the router can boot. Setting all reset, I need to restore setting back from backup.
I no idea why this problem happen cause before this I can off on without problem.
So any idea?
