Device Upgrade From Comcast talking points

  • Upgrades can be used on Wireless-G and Wireless-N routers
  • Customers with the Blast! or Extreme XFINITY Internet service will want to have a Wireless-N connection (for optimal performance) along with a 2×2 antenna
  • When upgrading a modem please be sure to have the DOCSIS version number
  • The DOCSIS 3.0 modem will allow customer to obtain the max speed possible

Tips to improve a wireless connection assuming all upgrades have been performed?

  • Make sure the wireless device is of the ground and upright position for max reception
  • Check neighboring wireless devices for interference
  • Make sure no one else can access the wireless device
  • Keep the wireless device away from walls, furniture, halogen/fluorescent lighting, electronic devices (i.e. TV, Radio)
  • Baby monitors and cordless phone
  • Customers who live in crowded apartments or condo complexes may have to many wireless devices in the area that will result in slower speeds (these customers should consider moving to a house)

Please note that customers do not have to upgrade the Wireless Gateway 1 (model numbers TG852G, TG862G, SMCD3DNV, TC8305C) or Wireless Gateway 2 (model number DPC3939) as Comcast regularly updates these firmware on behalf of the customer automatically.  Customers who do not have Wireless Gateway 1 or Wireless Gateway 2 will want to check for updates (or upgrades) once a month.
