      If your Arris Gateway's wireless Internet connection drops intermittently, it's often due to interference from devices like 2.4GHz cordless phones or microwave ovens. If possible, remove the source of interference. Alternatively, try switching to a different channel or enabling Protected Mode on your Gateway.

      It can take over 30 minutes to establish an internet connection the first time you power up your Arris Telephony Gateway, especially during peak hours. Ensure your Telephony Gateway remains plugged into AC power and connected to the cable system. Check that the Power and Online lights are on. If the Power light flashes for more than 30 minutes, contact your cable company. Verify that all cable connections are secure and that the coax cable isn't pinched or sharply bent. If you're using splitters, remove them and connect the Telephony Gateway directly to the outlet.

      If you are experiencing slow internet speeds with your Arris Gateway, the website you're visiting might be overloaded. If other sites load quickly, wait a few minutes and try again. Also, peak usage hours can affect connection speed, as can other communications on your LAN or interference with wireless connections.

      If you're unable to connect to the internet wirelessly via your Arris Gateway, begin by checking the indicator lights; the WiFi light should be on. Ensure your connection utility can detect your wireless LAN. If you have disabled “Broadcast SSID,” you'll need to manually enter your wireless LAN name in the connection utility. As a troubleshooting step, try changing your security mode to “WEP” or “disabled,” but remember to re-enable a security mode once the problem is resolved. A misconfiguration could lock out all access to the Telephony Gateway router, in this case, see Resetting the Router to Factory Defaults.
