Replacing the motherboard because wifi no longer works.

Recently my Lenovo ideatab s6000 stopped detecting wifi. Troubleshooting it the only thing i could come up with was something on the motherboard no longer works. I have looked at the back and reconnected all the wires. When looking at the ifixit manual on it it appears i am going to have solder to remove everything completely. I have a new motherboard coming in. My question is when I put the motherboard back in am i going to have to solder things back to their place? ie. speakers. Is there any way i can just reassembly the new motherboard without solder. Even if that means I lose sound or cameras. My only concern is getting my tablet back online I dont need the sound or anything. Thank you very much.
