Hi,
A guest account is an account for users who don't have a permanent account on your PC or domain. It allows people (guest) to use your PC without having access to your personal files. Users signed in to the guest account can't install apps or hardware, change PC settings, or create a password.
However, the Guest account allows a user to log on to a network, browse the Internet, and shut down the computer.
Normally, when using a wired/cable connection, the Internet gets connected automatically from the Guest account on the computer. Here, you may not be able to find the Network icon in the notification area on the Taskbar. However, the Internet gets connected automatically at the background and you should be able to access the websites using the browser.
But, when using a wireless/WiFi connection, this may not happen automatically from the Guest account when you login to it for the first time. You may need to set up the wireless connection once from the Guest account and then later on it should connect automatically.
First check if it is already connected to the WiFi network. You may open any browser and try connecting to any website using the browser.
If it is not connected, then let’s try accessing the “Network and Sharing Center” and setup a WIFI connection from there. Please try these steps and let’s know the result.
a) Press “Windows Logo” + “Q” keys on the keyboard and type “Network and Sharing Center” in the search box and press “Enter”.
b) In the “Network and Sharing Center” window, click on the link: “Set up a new connection or network”.
c) In the next window which pops up, select the option “Set up a new network” and click “Next”.
d) Wait until the WiFi network is detected and then choose your network.
e) Click on “Next”.
f) Enter all the details to set up the network and then follow the on-screen instructions to complete the set up process.
g) Now, open a browser and check if you are able to connect any websites from the browser.
Hope this is helpful. Please get back to us with the result.
