My CM 1000 lately has lost communication. Sometimes it quickly comes back on, other times I have to reboot and twice I've had to call TDS and have them send me a boost.
It went off around 10 am again today and I eventually had to reboot to get service back. I have attached today's log. Does this provide enough information for me to determine if I have a faulty modem or if another problem exists? I travel a lot and depend on my WiFi for many house operations. I can't reboot if I'm not here. Thanks for all help.

Re: Modem Dropout
Please post a copy and paste of the modems connection status page.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?

Re: Modem Dropout
The Cable Connection Status is Good
My Router is Synology RT2600ac with a mesh Synology MR2200ac in another location.
The cable is labeled Cat 5e
Are you saying you think the problem is not the modem, but the communication with the router?
Thank you.

Re: Modem Dropout
WE need to see that data from the cable connections page. There is a long page there of data that you can copy and paste here in the forums so we can see the values there. Help to determine more if this is a signal issue rather then a modem issue. Many factors on the ISP signal can be a cause of modems not working right. The events log points to that already.

Re: Modem Dropout
Ok, signals and power levels on the line look good. Correctables and Un-correctables are zeros which is good.
The ISP needs to take a look at the events log and resolve those items mentioned.

Re: Modem Dropout
When you say "items mentioned" which items are those?
Did the event log I attached to my original post help. I've been down briefly and then back up since I began the last two posts.
I really appreciate your help. The only way I will be able to communicate with TDS is to give them specifics, otherwise they will blame on my hardware. They are most difficult to deal with.
Thanks, Jim
