I don't know anything about qos. Linksys cable modem combo. I don't think I would like it if no controls by user. I see option in tcpip setting for qos but nothing more.
What I wan't is to open up the 15 kps upload for magicjack. 15 kps is my maximum upload for my cable. I tried other programs like cofspeed but no luck.
If your router/modem combo simply has an option to turn on QoS, then definitely turn it on. It probably is configured to make VOiP and other UDP packets high-priority, amongst other types of packets. Whether or not it will fix your troubles, I don't know. Its a shame it doesn't offer any more extended configuration.
Don't have qos on my lynsys cable/router combo, that I see.
I do notice putting my Magicjack on realtime and browser on below norm, the phone quality vastly improving. Though some tcp throttling when mj is in use would be a final improvement needed. (don't see improvement with gaming mode, yet. So unsure if any benefit could be gained with gaming mode.)
Other magicjack users are reporting improvements too. see: http://www.magicjacksupport.com/post45686.html#45686
My other quick question that I haven't had time to research is, did you do any i/o throttling in beta (which I am using.) I do alot of dvd and cd ripping/ecoding at night.
There is no direct I/O throttling in the current version(s) of Process Lasso. However, the priority adjustments Process Lasso makes often have the indirect effect of (re)prioritizing I/O. This is because CPU cycles are required to generate and process I/O requests, so the availability of CPU cycles can affect I/O. Additionally, in Vista and Windows 7 I/O prioritization exists and is derived from the calling thread's priority.
