We'd love to help and that shouldn't happen.
Out of curiosity, have you restarted your modem since regaining connection? If not, can you please try that out?
That said, if this does not solve it we do suggest you reach out to our tech support team. You can find all their info right here on Fido.ca and they're available 24/7 via LiveChat and phone!
Hope this helps, keep us posted on what happens and we'll go from there.
