Help with WEP / WAP and Shaw?

I am on Shaw and my new computer is not collaborating with my current WEP security wifi. The tech guy said that I need to update from WEP to WAP but a few people have said that I can’t do that with Shaw. Is this true? If so any solutions? And if not then can you tell me how to change it?
Please note that I am not a tech person so PLEASE use simple terms! Thank you!
