i have RB751G-2HnD i buy it from about 2 month it work with me fine but today it stoped without reason
when i connect it to power all led be come on except wirless led if i pluged lan to pc or to switch i got no result not connected in all rb ports
i tray to reset it but no result some time all led become off only led 5 on but if i pluged cable in it give no connection too
i dont know what to do with it
its hard to me to reach the destrbuter or resseler here 
after removing pastic cover i found that there are alot of rust inside the device i think drob of water go inside the rb
i clean it with cleaner its back to work but all of 5 lan port stoped only system work and wlan
i think no way the chip processor dameged some pin are disconnected from board if i found new one “AR7242” i try to reblace it
