I am unable to access the internet from public network connections.It shows that I am connected to the network, but will not let me go out to the internet or download email. I have no issues with this when I am on my home wifi network. Other people at these public locations do not have these issues, so I know it is not just that the router needs to be reset. I am sure there must just be a setting that I can't find, but I have wrestled with this for weeks with no luck. Any ideas?
