So today, I bought two new computers, a MacBook Pro and a Windows HP. I haven't purchased a PC in over five years but my son wanted one for gaming. Came home, plugged in the MacBook and voila! everything worked. Was able to connect to the local network no problem on the Mac. Plugged in the HP, I couldn't connect. It found the network but when I plugged in the 26 digit password, it wouldn't take. Troubleshooting said I had to unplug the router, so I did. Went back to try to connect, but I can't find how to input the password. All it does is say I can't connect to the network. So how do I find the dialogue box to input the password?
