Xinfinity indicated that my G36 has an issue with communicating with the G36. The following is there input:

We’ve noticed intermittent connectivity issues with your internet

service and have identified the cause to be a defect with your

Arris Surfboard G36 internet modem + router. Arris is working

on a software update that should fix the problem. Because the

update may not be available for several months, we have taken

steps in the interim to improve your connection and provide

you with the best possible experience. These proactive measures

should resolve your intermittent connectivity issues and provide

you with fast speeds, but your modem may not achieve the full speeds

included in your Xfinity Internet package until the Arris software

update is deployed.

If the above is correct when will there be a update and how do I update my G36?

It seems every few days (2-3) I have to restart the G36 to obtain the expected through put of my Xinfinity account.
