cm1150v modem with rax20 router keeps dropping internet every night with xfinity service

[Ngregsak]

I have been losing internet connection every night and having to reboot my modem and router every morning. It works fine during the day and evening but during the night it drops the connection and I cannot connect until I reboot. I have a cm1150v modem with an rax20 router ax1800. Any suggestions or help would be greatly appreciated as I am getting frustrated having to unplug and power up the system each morning.

Have you noticed if you have just the modem connected to a pc/laptop overnight, does it drop?
just trying to determine if its a modem issue or router issue.

Currently I am hardwired into the router, I will switch to the modem and try that.

[Ngregsak]

i was hardwired into the modem and was not able to access internet this morning. so assuming it is the modem that is causing the issue?

[Ngregsak]

But now the wifi is not working and the hardwired connection IS working

This doesn't make much sense. In one sentence you're saying the wifi isn't working (which it won't since the CM1150V isn't a router and doesn't have wifi), but in the next you're saying the internet wasn't available. 

Which is it? Does the internet work or not? 

If it doesn't it either means its the ISP, the line coming into the home, or the modem. do you have a screen snip of the cable connections page and the logs?

[Ngregsak]

hardwired connection is the only internet working currently. my wireless internet is not working. Snips below of requested info

[plemans]

Again, if you only have the modem connected, you won't have wireless. 

Did the hardwired internet connection drop?

[Ngregsak]

no it did not

[plemans]

so modem connection is stable. 

What firmware is on the router? 

[Ngregsak]

firmware on router is V1.0.2.64_2.0.42

[plemans]

have you tried a factory reset and clean install (not from a backup configuration) on the rax20?

[Ngregsak]

no i have not. how do i do a clean install?

[plemans]

Its a standard install but you just make sure not to use a backup configuration

[Ngregsak]

I DID A SYSTEM RESET AND CLEAN INSTALL. WILL SEE WHAT TOMORROW BRINGS

[Ngregsak]

lost internet again this morning and had to power off and power on 

[plemans]

try downgrading the firmware to version 1.0.1.58. do a factory reset and clean install and disable auto-updates. 

[Ngregsak]

internet did not drop over night. appears to be working fine.

[plemans]

glad to hear it!

[Ngregsak]

the issue is still continuing. it happened this morning and yesterday morning.

[plemans]

did you downgrade the firmware? 

[Ngregsak]

yes, did a factory reset of the router and am on firmware V1.0.1.58_2.0.31 and have disabled autoupdates. also did a factory reset on the modem as well.

[plemans]

do you have ipv6 enabled?

[Ngregsak]

YES, it is enabled on my computer. or do i need to enable it on the router/modem also? if so, how do i check that

[Ngregsak]

IPv6 IS DISABLED on the router
