Is my AC86U toast?

You may try to find it on the reference design. Specs sheet PDF file here.

Thanks that's the day a sheet for the other component that I replaced and I'm looking for the resistor next to it

There is a reference application in the same document with components values. Just find which one is missing on your PCB.

Hey guys! ok, i'm new here in the forum, i'm having a problem asking a technician to change the component on the board that burned out, does anyone have a picture of the pcb without the component to compare the tracks if it was broken? Sorry for my English, I'm from Brazil. Thanks!

 

[Tech9]

I don't have a picture, but the tracks are all visible when MT3125 chip is removed. Just give it to a technician who knows what to do.

Hello All! Few weeks back my RC86U had the dreaded 4th LAN light issue.

Any guidance on where to buy the chip for someone in the US?

Also how do I even open the router. I couldn't find any screws to open. Does anyone have a teardown video instructions?

I couldn't find any screws to open.

Two screws under the back label and plastic clips around the case.

I never ordered any parts - used donor routers to repair few others.

Yes, there are more screws under the label. AFAIK you don't need to remove the ones shown in the image. They are there to hold the foot stand.

The case is generally similar to the 68U (TMAC1900). So I'll point you to instructions on its disassembly
