I gave my permission and the wireless key number so she could use my internet, she typed the wireless key in it was not written down. She was desperate and I wanted to help.
I then forgot about it but I am now wondering if her ipad would have saved my wireless key number and she is still using it?? Just worried it will use up my allowance of internet and know nothing technical.
You can change your wireless key by setting a password. Not all people use the wireless key especially if it is placed somewhere where you cant always have access. But by setting your own password it will be used to access it. For example I have a BT home hub and use the wep key found on the back. If I have someone over and they wish to connect their laptop/phone they can just look at the back. However like my inlaws who also uses a home hub my FIL has a password on his. Therefore if I am there and I have a new device that I wish to connect and he is not in I cannot connect at all until he comes home to give me the password. Even though the wep key is at the back as well.
