DG860P2 WiFi Performance is Poor

If you experience issues with the WiFi connection on your computer/tablet/phone running slow or dropping, make sure your cable modem is in a central area and not obstructed by thick furniture or other objects. If you continue to have WiFi connection issues, try optimizing your wireless settings:

  1. Turn the cable modem off, and then turn it back on.
  2. Make sure the cable modem is powered on.
  3. Connect a laptop or PC to the cable modem with an Ethernet cable.
  4. Once you've connected to your modem, open a web browser and type in the address bar and hit enter. 

    You should see this page after step 3. 
  5. You will be prompted for a username and password. Use the following: 
    username: admin
    password: password

  6. Click the Apply button.
  7. Click the Wireless tab at the top of the screen.
  8. Make sure the "Tx Power Level" is set to High. It should be set to High by default. If you make any changes, click the Apply button on the bottom of the screen.

  9. On the left menu, click Advanced, and change "Wireless Mode" to G/N mixed. Click the Apply button if you make any changes. *note- very old computers and devices may only support the Wireless B standard, in which case need to leave this setting to B/G/N mixed for compatibility. Most hardware made after 2003 is wireless G or N compatible.

  10. If the above changes are not effective, select Basic from the left menu and try changing the "Channel" setting from Auto to a specific channel. Good choices are 1, 4, 9, or 11. Click the Apply button if you make any changes.
  11. If you continue to have wireless speed or connection issues, it may be a problem with your environment or hardware. Plaster or concrete walls will affect wireless range and stability, as well as old cordless phones, certain garage door openers, and faulty WiFi devices may be the cause.
