Hi all, I bought the WRT54G v2.2 and installed DD-WRT primarily to control QOS better so that I can use voip/skype without having to stop/start other programs on my networked computers, but it's not working as well as I'd heard others report it. My system is as follows: Sipura spa2000 on port 1 Mac G4 on port 2, which is my server and generally used for backups, some torrents, music and movie library etc. Mac powerbook, normally wired to port 3, but occasionally wireless (802.11b) Mac powerbook, wireless (802.11g) My DSL connection is 512Mb I've set the QOS settings as below Uplink kbps 256 Dnlink kbps 440 Services Priority SIP and skype as Premium HTTP and POP3 as Express bittorrent and edonkey as Bulk Haven't set netmask or Mac priority Port 1 (sipura) premium Ports 2,3,4 standard. Questions: Should I set the sipura mac address in the mac priority as well as in the port priority and services priority? I find that with downloads running, I still get broken voip conversations. Should this setup give the sipura priority over everything else? Should web browsing take priority over the downloads in this setup? Any other suggestions on this gratefully received as I'm just starting to learn about QOS. Cheers, Justin.
