Minimally Qualified Modems

You may also choose to buy a modem that has passed minimal testing to confirm that it will not cause harm to the network. Though permitted for use on the network, we recommend against using minimally qualified modems because they have not yet been tested to confirm their capability of rendering Internet service tiers without interruption or other service degradation. Minimally qualified modems may not have the capability of delivering the purchased Internet speed.
