Strange thing: My roommates and I moved recently. We have a cable modem broadband connection, which also handles our Vonage service. I have a G5 with a wired Ethernet connection to our router, and my roommates' PC have wireless connections to the same router. Whenever we receive a call the phone quality sucks bigtime: the listener on the other end only hear the call very choppy and cuts in and out. Whenever the Mac is taken out of the connection, the quality goes to normal-crystal clear. I have also run tests online (Cnet's Broadband Meter) and the connection ranges from 820 kbps-1300 on the PCs. Once the Mac is connected back into the router, all computers including the G5 go down to around 100-180 kbps. Anyone know what to do to help?
