[kwlug-disc] [OT] Diagnosing voip and Tomato

The only time I find a small degradation is when I am on the phone with my dad, 
doing desktop sharing while someone else is watching a movie and other people 
are doing the normal you tube and browsing. (At my home there are always several 
devices accessing the Internet). 

Just regular browsing and YouTube do not give me any noticeable degradation. 
E.g. I regularly have conference calls from home where I VPN to the office, and 
remote to my office computer (RDP), with no noticeable degradation in the call.

Movies seem to be the main offenders (1.5 GB/hour) 

I don't mind that small degradation at home talking to my dad while someone 
watches a movie, I thing I would if it was a business call.

Here's where I'm puzzled.  Seems like plenty of people using Voip on the list.  
Am I the only one experiencing this problem repeatedly?  Or does everyone else's 
calls degrade as soon as the kids get home from school?

For bandwidth management on routers that seems to work, try the Gargoyle 
distribution:  http://www.gargoyle-router.com/  It is OpenWRT-based and runs on 
the Linksys-class hardware.  You can throttle users by usage or IP.  It tires to 
do QOS as well, but I have not tried it myself.    On Thu, 2011-02-24 at 20:31
