First thing to perform would be a full restore and/or update on your iPad and then see how things work. If nothing seems to be working even though your perform both an update and a restore, you might have damaged the wifi antenna when you removed the digitizer which is a frequent problem when opening iPads. The wifi antenna is located at the bottom very close to the bezel. Depending on which way you slided your tools to remove the adhesive you might have hit something. Good luck!
