> our wife is not working
That is not a lot of information to work with. Any "multiple-spouse" arrangement (2 husbands with just 1 wife) can have issues.
Does your wife work if she takes her computer/tablet/smart-phone to someplace offering "Free Wife", such as a Public Library, or a Starbucks or Macdonalds or her mother's home? That would prove that the device is OK.
Does your own computer/tablet/smart-phone connect to your Shaw router in your home?
