At work we have a WiFi network which when you connect to it, it defaults to a login page (similar to many public WiFi networks that require a logon). Normally this connects fine but recently my iphone 4 has been asking if I want to connect to the network then asking for a password (note its not possible to login to the wifi this way) rather than defaulting to the login webpage. If I cancel this it just uses 3G instead. Apologies for the lack of technical explaination but hopefully someone will know what I am on about! Thanks in advance!
