I am running a Linksys WRT54GS router with the current version of HyperWRT firmware. I have the Nuvio TA installed in port one of the router. I had the router configured to give priority to the mac address of the TA. I have the upstream bandwidth set to 275. I have tested this making calls while running speed tests and it does seem to be limiting the upstream and downstream bandwidth a little. It will not though limit the bandwidth to the point where call quality is not impacted. As an example yesterday I made a call at the same time my e-mail decided to send my outbound mail with some large files attached. The call quality immediately went down to the point where the conversation was almost impossible. I happened to be running PingPlotter at the time and times went as high as 2000+ MS. The e-mail program is running on a PC which is connected through a wireless port and I have no QoS set up for anything except the TA mac address. Anyone have any thoughts on this? I would have expected the QoS to give all needed bandwidth to the VoIP. Is there any advantage to configuring the QoS by port instead of mac address or doing both?
