I have internet at 140mbps. Using an older modem -ARRIS SB6121 that is apparently no longer supported. Both my wife and I work from home. Have an ooma telo that works just fine.
The strange thing is, when I am on calls via skype or gotomeeting, without fail, after about 4-5 minutes, I can no longer hear any audio. THe people on the other end of the call can hear me. Skype and gotomeeting eventually error out, and I have to reconnect. My laptop is hardwired with ethernet to the router. this has been going on for around a month now. Is it worthwile trying to upgrade to a new modem?
THank you for your input!

If you are using Wifi it's best to switch to an Ethernet cable connection if possible while checking the reliability of your connection to Comcast.
If you can't find the problem or you'd rather have Comcast do the troubleshooting, call them at the phone number on your bill or 1-800-Comcast, or chat with them using the Internet Support option at https://support.xfinity.com/chat. If they can't fix the problem remotely, insist they send a tech out to identify the cause and correct it. Loss of Internet service is often due to a poor connection between your equipment and Comcast's network, usually in or near your home.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device, or anything outside your home, you shouldn't be charged.
ETA: A note on http://mydeviceinfo.g.comcast.net/device.php?devid=365 says:
Both leased and retail versions of these devices are End of Life (EOL) EOL’d and will no longer be activated on our network. Existing network devices are not affected.
Be advised, that modem is an old 4 channel dinosaur !! As you stated, I too can no longer find it on their "approved" list. Technically you would be better off with a modem that offers more channels to help alleviate any forward path / downstream congestion issues if that is indeed the problem. Good luck !
Be advised that you should still follow .@BruceW's troubleshooting advice !
If you do decide to upgrade your modem, this one will serve you very well for your speed tier !! And it's cheap !;
Hmmm... It does here;
Good for up to 373 Mbps.
IMO, and most I've ever seen here, this is one of the best modems ever made !! I'm using one as we speak and it's been rock solid for years !
