Fido Internet connection problem

It was two days my Fido data plan (internet) was down. I called to customer service and they told me you should restart your phone to get new settings. I did it. After that some internet sites don’t work. Such as : wap.fido.ca or fring.com
Obviously, some of my internet applications can not take established connection.
I use N95.
Note: When I change the Access Point to non-Fido access point everything works fine.

Do you have any Idea?
