Problems of calling on sites and LK

All kind time of days, I had a problem with surfing. Sitting through Wi fi. Possibility to connect cable no. The essence of the problem so I go for example to purse Payeer, advcash or some forums where you need to go to the page to login. In the end click login, go to BOS, you press like the message and throws me to the login page and all povtoryaetsya. Cleaned cookies, cleaned all the browser history and everything else, removed the plugin on the browser. Downloaded another browser(Opera) helps nothing. There's the same thing. How to solve the problem?
