This is way simpler than it sounds at first glance and can be done by following the next steps:

  • Turn on the wireless modem router and the device we are going to be using to perform the process with, either being a PC, laptop or mobile device.
  • If we use a computer or device with a LAN port, connect the modem to the computer using an Ethernet port on the back. If we are using a mobile device, connect it to the open WIFI be default provided by the emitter. Now both devices should be connected.
  • With the computer or phone connected to the Arris router, now open a new tab or window on an updated internet browser. Chrome, Edge or any other will do the job.
  • On the URL bar on the browser type down the router´s default IP: “”.
  • At this point, the router will ask for access credentials: for Username is the word “admin”, and for the passphrase, the user must access the website, enter the device´s release date on the back and the password will be provided.

Now that we are in the Arris TG862 and its general settings, we are going to be able to establish a customized password for the wireless internet connection. To do so, follow the next steps that are quite simple to carry out:

  • On the home screen, click on the option “wireless setup” that is available on the main menu of the Arris modem router.
  • By doing so, a new options menu will appear with all the functions related to wireless connectivity and its security. To begin with, let´s click on “SSID” and complete the name of the network to change it.
  • On the next option, select the type of the encryption the WIFI password will have, being the WAP2-PSK the one to choose due to its security. Do not select “WEP” in any case since is an obsolete, vulnerable and out of date security protocol.
  • On the “passphrase (pre-shared key)” option, enter the new password, which must be at least 13 characters long, and for best security is recommended to included numbers and letters to apply a strong password.
  • Click on “Save” and changes will be applied after the router gets rebooted.

It is recommended to change the passphrase periodically and not giving it away to the first person who asks for it.
