wifi

@3Cts your phone should have saved the credentials for your home network, and every other network it successfully connected to.  On your phone, open your settings, find the Wi-Fi section, and tap the name of your home network.  If this doesn't work or you still need to enter a password, you can find the original password (and original network name) on a label on the gateway.  This should work unless you changed it. If you did change it but you can't find it, you will need to reset the gateway.  I don't know the procedure for this without some research, so please see what you find and report back here.
