We trade in Leeds, and have a few areas of bad net connection, and one of our users has a big problem with this, she has 90% of her business is schools which will not allow her access to their wifi. She does the same as us, when we go outside the building we can usually get connection, or sometimes I wait until i'm back in the office or home and sent whatever it is then, I'm afraid we cannot do anything about this issue, although I must admit no one really thinks it a major issue, but only you will be able to assess how badly this will affect you.
