      My guess is that you had a transient or short to the 5V or the 3.3V power rail, which damaged both U11 and the WiFi module. So I think you need to replace the WiFi module. The good news is that it's easier to solder than U11 because the pads are larger.

      The correct replacement part is ESP-12S, or ESP-07S (the S is important) if you want the version with external antenna. These are are readily available on eBay.

      Please note, the other component that is easily damaged by over-voltage on the 3.3V rail is the main processor. So I suggest you check first that the processor is not getting hot (slightly warm is normal) and the other functions of the Duet are working properly.

      From the photo, it looks like your Duet was revision 1.04, in which case it might still be under warranty.

        @dc42 thanks for your informative answer. the WiFi Was working before i tried my soldering skills on the U11, thats why i wanted to figure out what i might have damaged 🤕
        the Board is only 6 Weeks old thats why i asked the Internet Shop where i bought It if warranty is an option, but they refused. Do you think i should ask at the headquarters in uk?

          If the internet shop was one of our official distributors (see the list at the bottom of https://www.duet3d.com/DuetWifi) then they would typically refer warranty enquiries to us, unless they had reason to believe that the Duet had been abused.

            they asked me to open this forum Post and After the First few posts they thought i damaged it myself, because the most likely reason was that i created a short.
            it would be really nice if i could get warranty because i didnt Do anything harmful to the Board (at least i dont know about something). Do you think i should try to contact your Support Directly?

              I'll discuss this with my colleagues and we'll get back to you, probably by email.

                    I'm sorry, one of my colleagues should have got back to you. I have chased them. We agreed the warranty replacement.

                    If you purchased directly from duet3d.com then you will need to complete the warranty form, see https://docs.google.com/forms/d/e/1FAIpQLSdyf6gGP_ncZachWi2HH7qx1kc5TE9WeEbz83VFBckm1JBXbQ/viewform.
