Where to set QoS and sound improvement
Posted: Sat Mar 06, 2010 7:44 am
Here is my equipment and setup:
1) Motorola SB5120 cable modem
2) Netgear WNR2000 v.1 router
3) Ooma Telo
4) House wiring connects to the phone jack of Telo, and disconnect from phone company at the outside network box
4) Internet Service: Comcast Performance, download 20 mb/s, upload 2.5 mb/s, ping 99
The Ooma Telo unit is downstream of the Netgear router. The Netgear has the option to set QoS. I set the QoS using the Netgear by using the MAC id of the Telo at the highest priority. I did not touch the QoS setting for the Telo (at first). With this, there is no sound breakup even when I was doing heavy downloading. My question is whether there is anything gain by further adjusting QoS for the Telo unit?
With regarding to the sound quality, there was always a humming background noise with burst of buzzing during the quiet moments of a conversation. I contacted customer service on this issue. The suggestion was to adjust the QoS setting by hooking up my computer to the Telo unit. I brought up my web browsers (Firefox and IE). Both could get into the Ooma setup page but froze after that. We worked on both browsers for a while then it hit me to disable the antivirus software (KIS). That resolved the browser issue. I noticed the QoS setting in the Telo unit was at 384 kb/s upoad and 0 for download. CS person advised me to up both numbers for up and download. I tested the sound after hanging up from CS but it did not seem to make any difference on the humming and buzzing. I then tried the fax mode. There were some reduction in the humming but the burst of buzzing was still there. With nothing better to do, I changed the wifi channel on the router. For reasons unknown, the humming is down to hardly noticeable level and the buzzing seemed to be gone. I thought I would share this with the Telo users that still have the humming and buzzing problems.
Going back to the QoS setting, I think it would make sense for me to have 0 for both up and download in the Telo and just let the router do the controlling.
