If you find yourself  getting connected ok at school and you can't get online at home, the problem could be due to filtering that might be used on your home connection.  GRACE uses Securly for filtering.  Securly may not work with other filtering in place, like OpenDNS (which often gets set up within a home router).  The solution is to turn off OpenDNS in the router and use the parent portal for Securly to manage student access while off campus.
