Wi-Fi keeps dropping. Router rebooting

[Knowsstuff]

Bought Google Wi-Fi at Costco like 6 months ago. Working good. Then all of the sudden it drops constantly and reboots. Increased from 250 to 400 internet. Hard wired to modem which is a new Arris 3.1 docis. Tried rebooting. If these products last only 6 months then will return and go back to Netgear Nighthawk.

Hey, Knowsstuff.
Sorry for the late response here, but I wanted to check in to see if you were still having this issue and to see if you have done any troubleshooting so far. If you still need help, let me know and I'll be happy to work on this with you.
Thanks.

Hi, everyone.
As we haven't had any activity here recently I'm going to go ahead and close the thread. If you have more to add, feel free to start a new discussion.
Thanks
