CM700 in and out connection issue
I have been having in and out connectivity issues lately. I have read some of the past postings but I'm not sure how I can solve it. Could someone please help me? I am very dim on internet connec...
Thanks for your reply!
The host wifi router connected to the modem is Deco AC1300. I will need to replace the cable between the modem and the router with CAT6.
Regarding the connection up to the modem, I need to check with WOW.
WOW was blaming the modem not correctly channeling between 2.4 and 5.0Ghz, but I will check with them again.
Turning off and on the modem I have tried but I still get this issue...

Thank you again for your reply and guidance!
"WOW was blaming the modem not correctly channeling between 2.4 and 5.0Ghz" < Be sure they understand and you understand that this model modem does NOT have a built in route or wifi.
Also those errors and criticals in the event log needs to be reviewed at addressed by the ISP.
Thank you for your reply again!
I have arranged a technician to come this Saturday!
While waiting I still have connectivity issues and I see something new in the log.
Not sure what "Map Request Retry Timeout", "DHCP RENEW WARNING - Field invalid in response v4 option", "TEK Invalid - Invalid Key Sequence Number" mean.
(Not that I understand the others lol)
I never had such connectivity issues before since I moved in 4 years ago, so I am wondering why this is happening frequently only now...

Also you could ask them if you can use one of there modems to see if the problem continues with there modem as well. Rule out a CM modem or ISP issue.
Let us know how it turns out.
Thanks, and will do! I will provide an update once it's reviewed by a technician this weekend.
