The alternate hookup method for Ooma telo is recommended to give phone usage priority over internet activity. This connects the cable modem out to Ooma telo Internet jack, and Ooma telo Home jack to the “system” (my router’s modem input). This works, but causes major losses in download and upload speeds. My tests were run using various servers using speedtest.net. My cable internet provider is Charter.
As an example:
Ooma telo connected as shown in Quick Start Guide Step 2. Test to server Suma Fiber in SLC:
Download - 24.43 Mbps, Upload - 4.32 Mbps, Ping 46 ms
Change connection to Alternate Method, use same server:
Download - 13.35 Mbps, Upload - 0.48 Mbps, Ping 46 ms
Download was reduced ~45%, and upload ~89%. Ping time was the same. Is this performance loss expected? Or is this a problem in my specific telo?
