I'm lazy to open up my DIR-868L Rev.A1 to check, but if you post uncropped full-size photos of both sides (of the PCB) then I may be able to guess. If the photo size is too big, you may need to upload your (PCB) photos somewhere and paste the links here to avoid moderation.
Do you have any multimeter?

What's the guide/file you used to play with CFE?

Use a multi-meter to find pins on any router, simply use a shield for ground on meter to find 5v pin and then find ground pin, then the other two are rx and tx.
Don't use 5v pin when connecting serial !!
If putty reads garbage switch rx & tx around.
Hope that helps
