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?
Thank you for your response. Yes, I did see that. However, if +9dB is too high, then why does +13dB work flawlessly? Since removing the 3-way splitter increased the power to +13dB, it has worked flawlessly. I haven't had a single disconnection. I have to get ready for work, but I am attaching a snapshot of my connection status while I was experiencing the difficulties. I'll see about getting the log tonight. Thanks again.
If it works fine without the 3 way connector, I'd really be suspicious of the 3 way connector.
You can run your signal hot but it can cause issues and longevity problems.
that's why we recommend it at lower levels.
I see. (Although that same 3-way splitter worked fine with the Xfinity modem). Ok, is there a specific 3-way splitter that is designed to function with the CM1150V? (i.e. can you recommend one that should work with it)? Thank you for your assistance!
