My Internet was working fine but it was time to upgrade old Xfinity equipment. I purchased the G36 and it drops wifi off an on all day. Unfortunately it's been more than 30 days so I cannot return to Amazon. Xfinity says the g36 has major issues with their system and don't recommend it. How can I warranty this product that doesn't work? Will a new g36 work or do I need a different model?? I've spent hours on the phone/chat line and am very frustrated. Where do I go from here?

We apologize for the inconvenience. To help isolate the issue, could you confirm whether the connection drops only over Wi-Fi or if it also occurs on a wired connection?

If it happens on both then we recommend checking the cable signal levels within the gateway. If the signal levels are out of the acceptable range, they can lead to the kind of connectivity issues you're experiencing.

When the signal levels are within the recommended range, your modem can maintain a stable, high-quality connection to the internet

Please refer to the link below for instructions on how to check your cable signal levels:

If you find that the signal levels are not within the recommended range, we suggest contacting your Internet Service Provider (ISP) to have them reviewed and adjusted as needed.

The signals are in range, Xfinity tech came to the house and verified all connections are good. What do I do next? We're losing wifi, I don't have anything hardwired to the modem/ router

In this case, we recommend changing the Wi-Fi channels. Adjusting the Wi-Fi channel can help improve your network performance by reducing interference from nearby networks and devices.
