@droftarts the old and new chip were both the 07S..
This is the chip I used. (Never mind can’t post links.. it was a 2 pack off Amazon for $7.48)
It looks identical to the old one. But I’m definitely not an electronics expert. I appreciate all your all’s replies.
Hey there, so I was given a Vivedino Troodon 1.0 that uses a Troodon specific board that runs on RRF.. so I know this doesn't apply specifically to Duet. Hoping maybe you all can provide some help though.
I had to remove the old wifi chip, an ESP-07S chip. I had to replace it because the pad where the antenna connection (U.FL) broke off.
I think I got the new chip soldered in correctly, but now I'm just getting this from YAT:
Any guidance or advice would be great! I was going to link the controller on their website but I can't post links yet... thanks.
@droftarts Yeah buddy! I'm connected, did that M552 S0, M587 and set up network and I'm now connected. I should've tried that before commenting again. Thanks again for your all's help! It seems really obvious now that I have to upload the firmware to the new wifi chip 
lol
Thanks for helping me out! We can close this issue
