Dead ethernet ports

After changing capacitators in my RB450 (successfully) I suddenly experienced a paranormal need to solder some more :slight_smile:
So I changed the ethernet transformator (is it called coupler or what?) on an old 112 board. But still no ethernet link. Could the problem be further in the chips or I just soldered something wrong?
Has someone successfully resoldered those transformators/couplers? I got it from a faulty motherboard, maybe it was simply dead…
Ideas?

P.S. I know those boards are old, but they can work as access points very well. Some even have quite high level licenses + additional features.

Hi, I think it’s broken ADM5120 No reason repair this RB - PCB is sensitive to regain reflow process and lost some via. Like wireless station + AP it is not so good - is not enough memory. RB532 is much better :))
