Turning Off Admin Password For New Internet Connections?

We are a small business with a number of field workers who are out and about all the time. The will need to pick up new connections at hotels and the like, but every time they want to add a new wifi connection they are required to put in the Administrator Password.My question is, is it possible to turn this off, so that they can add whatever network connection they want but still keep the admin password for adding new programmes and the like.
