It’s usually when your laptop, smartphone or tablet has been connected to a particular wireless hotspot that connection problems arise – it uses the same settings to reconnect but without going through the redirect/sign-in page properly, connecting to the local hotspot’s router but not to the Internet. To fix the problem make the device forget any hotspot it has been connected to.
If a “Remember this connection?” message appears, decline the offer and delete any public hotspot.
To do that in Windows 8/8.1, click the Wi-Fi–network icon in the bottom right corner’s Notification Area. (If you can’t find it, enable “Show hidden icons”.)
A list of available connections should appear. Right-click on the hotspot’s name – its SSID – and enable “Forget this network”.
In Vista and Windows 7, right-click the Wi-Fi–network icon in the Notification Area and click on Open Network and Sharing Center. When the Network and Sharing Center opens, click on “Manage wireless networks” in the top left corner. Right-clicking the hotspot’s name and clicking on “Remove network” or Delete gets rid of it.
If connecting to a particular hotspot is still problematic, try turning off your wireless connection, then turn it back on. Restarting in this way often clears problems, just as restarting a computer itself often does. The following article shows the ways in which Wi-Fi can be turned of in Windows 7. Similar information is available on the web for any other version of Windows.

Unfortunately, there is no way to bypass having to go through the sign-in pages and accepting the terms and conditions involved in logging into a wireless hotspot, but with no hotspots installed in the system access to a new hotspot should be a simple matter.
