The hotel I’m staying has a system of connecting to the WiFi using voucher codes through a login page. When I first arrived I logged in with my iPhone and it worked. Then I tried connecting to my iPad and windows laptop but I have the same issue: whenever I introduce the voucher and click connect the login page refreshes without connecting. They gave me a new voucher but the problem remains the same. It’s probably not a voucher issue as I don’t get an invalid voucher error, the login page just refreshes. I tried forgetting the network on my iPhone and reconnecting again and now I have the same issue also on my iPhone. The manager says I’m the only one with these connection issues. Any ideas how can I fix it?
