comments were made that high values in "Maximum TCP delay: " could indicate the need for a new modem.
My "Maximum TCP delay:" has consistently been high between 400 ms and 500 ms.If that tcp delay is consistently high like that, I think it is time for a new modem.
I tried researching "Maximum TCP delay: " and saw that numbers over 200ms are bad, but it also looked like high delay might be acceptable if "Download TCP forced idle:" is low. My modem is showing "Download TCP forced idle: 0 % "
My call quality is sometimes less than good and I would like to have it as clear and dependable as possible. I use AT&T DSL and have the AT&T 2-Wire 2701HG-B Gateway modem using DMZplus address to Ooma Telo and then Telo to wireless LAN for home distribution.
Do I need a better modem?
Any suggestions for a great DSL modem for great Ooma VOIP? cheap?
