Step 1
Netgear provides a setup wizard to help configure the router. Log in to the web based interface by typing 192.168.0.1 in your browser URL field. Enter "admin" and "password" in the Username and Passowrd fields, respectively. Username and passord are case sensitive. Click OK.



Step 2
Go to the WAN Setup menu. Select Custom next to MTU Size and enter the desired MTU in the ajoining box. Click Apply.
