rgreenpc:Jeff - Not sure then as I have a gigabit network with no flow control issues.
I had this issue with the Internet TV previously and had contributed to my network setup, therefore, I made some changes. As a note, everything below is hardwired.
First, my original setup was:
XPS 420 connected via Gigabit to a Linksys SRW2024 Gigabit switch (enabled Tx flow control) which was then connected to a Linksys WRT600N router. I have three DMA2200s and they all experienced pauses after about 5 - 10 secods of video as well as the voice wouldn't always match to the video as well as the video was choppy.
My first change was:
I then purchased a Linksys SRW208G 100 Mb switch originally thinking that it would fix the issues as I felt that they were Gigabit related. However, with the XPS 420 and the DMA2200s on the 100 Mb switch, I still had some occassional studdering and choppiness. This totally blew my 100 Mb versus Gig issue, but I did now have a full green graph on the network optimzation/tuning which I never had before with the Gigabit switch.
Therefore, my final change, which has cleared everything up, is as follows:
XPS 420 connected to the WRT600N router via Gigabit with flow control Tx enabled. The SRW208G is connected via it's Gigabit uplink to the WRT600N and the three DMA2200s are connected via 100 Mb to the SRW208G.
I nearly pulled my hair out trying to get this to clear up by reconfiguring my switches constantly, but in the end, these final hardware changes and moving to 100 Mb seemed to have fixed my issues. Also, in the end, I don't know if moving the DMA2200s back to the SRW2024 would cause any issues, it would be overkill as the DMA2200s are only 100 Mb to begin with and I have freed up several ports on the SRW2024 that were needed for other networking ports in other rooms of the house.
Hope this helps.
