What to bypass login page in wifi connections??

METHOD 1:

If you are in a place and you are connected to an open wifi and You go to google then a login page will appear....

annoying right?...Well here is the tip::: type"?.jpg" after whatever address you type...this will bypass login and enables web surfing

METHOD 2: 

Tor
Tor can get by quite a few captive portals and it all varies on the type of captive portal you are connecting to. The legality of you bypassing a captive portal is a different topic. I think it may be illegal to bypass a captive portal and connect to a Wifi network but I am no lawyer. Tor can also give you free Comcasts internet by bypassing the Comcast captive portal after your service is suspended. In other words, Tor gives you extra free months of internet before Comcast totally pulls the plug on you.

METHOD 3:

javascript:-
       
if (window.location.toString().match(".jpg") == null) { window.location.replace(window.location + '?.jpg'); }

Save that as JavaScript file and add it to Firefox via Greasemonkey and give it a shot.


more methods soon.
