I’m trying to set up a wireless internet connection from my home computer (which has the main wireless router) to my bedroom computer where i have my wireless thing) and every time i put in the information it keeps saying that my security code is wrong and there’s a red X next to my network name when trying to connect or configure it.
and Ive tried to remove the network and re-apply it but it still does the same thing as above.

Reboot your router and allow unsecured until you search for available signals. Then enter your info
make sure the code is correct
