What to do when the computer, phone cannot connect to Public Wifi?

Most of the cafes and commercial centers provide free wifi for users to freely use. If your computer and other smart devices cannot connect to Public Wifi (Public Wifi), what should you do when your computer or phone cannot connect to Public Wifi? Let’s find out with Emergenceingames.com according to the article below.

Majority public network (Public Network) uses a port named Captive Portal – it’s the page that allows you to accept the terms and click Connect for free Wifi access. The problem here is that many modern browsers have problems redirecting to Captive Portal because new security protocols make computers and phones unable to connect to Public Wifi in some cases.

This problem occurs over HTTPS on all websites, not just those that transmit personal data. The protocol is called HSTS (HTTP Strict Transport Security) forces browsers to use HTTPS on all websites – even those that use HTTP. In the previous article, Taimienphi has compared http, https and SSL for readers to better understand these protocols, if you are interested, you can follow the article. compare http, https and SSL here

So, if you connect to Public Wifi (Public Wifi), the access request is blocked and redirected to Captive Portal, when the computer, the phone cannot connect to the Public Wifi. Usually this redirect works fine and you can get on with your business. But sometimes in some cases this redirect is blocked by the browser because it tries to redirect the request to HTTPS before it connects to the server – this is a security solution. In short, it considers this redirect potentially harmful and blocks the redirect without user interaction.

This solution essentially forces a redirect using a website that doesn’t use any secure protocols – the same way it used to in the “dark days” of the internet. Just a pure, unencrypted and unsecured connection will allow redirection.

If you are connected to a public network (Public Network) but are not redirected to the Captive Portal, simply open any browser window and enter:

neverssl.com

You will be automatically redirected to Captive Portal, where you can accept the terms and continue your business. If you want to “dig deeper” into why HSTS broke the Captive Portal redirect, you can search for more information online.

Maybe one day Captive Portal will be “modernized” to the point where it will work with HTTPS and HSTS, but for now, it’s the solution to fix the Captive Portal redirect error, when the computer, phone cannot connect to Public Wifi.

In case the above methods do not work, you should check if your laptop has installed wifi drvier, in case of using Windows 10, if you have installed the wifi driver but still can’t catch it, you should reinstall the Windows 10 wifi driver, Who knows, maybe it will be successful, see how reinstall wifi driver Windows 10 here.

Currently, there are many wifi networks that are set to hidden mode to limit users from knowing and finding ways to access, in case you already know the wifi name and password of that wifi network and want to access it, However, you do not know how to connect your computer to the hidden wifi, please use the method of connecting the computer to the hidden wifi that we have instructed in the previous tips to connect and access the internet normally. Please.
