What I think you are experiencing is this: Consumer grade equipment and consumer grade dsl.
I've never used consumer grade routers except for one way... turn off dhcp and add a static local route and enable the wireless on it as an access point (like at home, pfsense with a linksys router configured that way so the kids can wii on a snow day). Saturating your upload is EASIER than your download, because in an ADSL link (or cable modem), the upload pipe is a fraction of the download. You'll almost alays notice a "bump" in the voice clarity as QoS rules are beginning to exceed, even momentary, even if configured properly. I am liking to shaping and QoS changes in pfSense 2.0 (running a Beta and playing with it). Improve it? Maybe run tomato or cactus on it instead of the run of the mill firmware, if its capable. I'm digging the new dlink wifi ap/router with touchscreen and usb for network storage, plays very well with a real firewall fronting it too. http://www.networkworld.com/community/node/49592?ts0hb&story=cespkg On Wed, Jan 13, 2010 at 3:54 PM, Tim Byng <[email protected]> wrote: > Thanks for the feedback!
