Optimum is my  provider and have been doing the zoom meeting for years,  The problem started with a new G34 wifi modem.   While in Zoom meeting either the guests or me , the host, freeze, the internet connectioin is unstable message appears and zoom reboots and I have to unmute.  Never had this problem until I got a new G34.  Gene had a similar problem with a G33 and ultimately found it was the modem.  Is it the new G34???  If so Im very disappointed.  My previous Modem was an Arris SBG7600AC2 where all the ethernet connections quit working.  I followedd all troubleshooting recommendations of power cycle, disconnect cable and hard rest.  Being out of warranty I bought a new G34 and now a Zoom  problem.  Please help

Could you please confirm the name of your Internet Service Provider (ISP) and the speed plan you’ve subscribed to?

Additionally, is the connection instability occurring only over Wi-Fi, or does it also happen when using a wired connection?

Lastly, apart from Zoom, are any other devices or applications affected when connected through the G34?

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.

downstream signal levels are OK, Upstream power levels are 33 to 35 dBmV.  Optimum was just here lasst week and said all signal levels were OK at the modem.  SO?????????

The cable signal levels displayed on the interface page reflect the signals being transmitted by your Internet Service Provider (ISP).

If you notice that these signal levels are outside the recommended range, we suggest contacting your ISP to have them reviewed and adjusted accordingly.

While ISPs may have their own approved signal ranges, for this gateway to function properly, the signal levels must align with the acceptable values outlined in the reference article provided.

Cable signal levels are within range, downstream 5.800000 - 6.900003 dBmv and SNR of 37.605377 -38.605377 dB.  For uupstream 48.0010300 - 49.7770599 dBmv.  Optimum has been here 3 times.  and assured the poower levles and SNR for every channel are within specs required by ARRis.  Ihave disconnected any other WIFI routers.  THis problem is continueing for 2 months ever since I got the new G34.  I can no longer run Zoom meetings wiithout Zoom indicating intermittant loss of internet, freezing and automatically restarting.

If you are using a Wi-Fi connection to access Zoom meetings, we recommend switching to a different Wi-Fi channel. High traffic on your current channel can cause instability in the connection.

Please refer to the link below for detailed steps on how to change your Wi-Fi channels.

I have been experiencing the same issue with the G34 modem for quite some time. I contacted the support team and followed all the troubleshooting steps they recommended, including the configuration changes. They mentioned that the modem would gradually start working properly after some time, but that never happened — the issue has continued without any improvement. When I use a wired connection through the router/modem, I have no problems with Zoom, Slack, or Teams calls. However, when connected via Wi-Fi, the network keeps dropping. This clearly indicates a modem issue, as my Xfinity connection itself is perfectly stable. At this point, I feel that purchasing this modem has been a complete waste of money, time, and effort. I paid nearly $200, and for the last four months I have had to rely on a wired connection for my calls despite investing in an expensive modem that was expected to perform reliably.

I continue to have intermittant loss of internet,,  This is  shown by pinging google, one account notifies me when there is internet loss and unanble to run zoom meetings.  After many hours with Arris support and Optimum out to my house 3 times enoug is enough!! The calls to Arris always resulted in some analysis of the modem router performance followed by changes in the settings. And then wait 24 hours.  I have disconneted another router and all hardwired Lan  connections.  Problems remain the same.  Couldn’t get Arris to replace the new G34.  So I did.  Problems are all gone!!!! And never again will an Arris device be pruchased by me.
