Narrative:

On climb out; we encountered what may have been wake turbulence causing the aircraft to bank to the right. Upon rolling wings; level we received several caution EICAS messages; angle of attack limit fail; windshear fail; and stall protection fail. I continued the climb while the captain ran the QRH for the listed caution messages. He also contacted dispatch via ACARS for guidance on how to proceed. A few minutes later in the climb; we received an autothrottles fail message. We discussed returning to ZZZ. The captain contacted dispatch through radio and advised them of the error messages. They said they would prefer we return to ZZZ. We agreed and I contacted center to work out a plan for return. The captain briefed the flight attendants and the passengers. We completed all briefs and checklists and were vectored by ATC to 34R in ZZZ. The approach and landing were uneventful and an emergency was not declared. After landing; we received the ads 1 and ads 3 failure messages on the EICAS. We returned to a gate and coordinated with maintenance.
