This is a repost from the HTPC section. It seems like this thread might be a good place to get suggestions and/or questions answered. Dilemma below...
I am trying to improve the performance of my MoCA network. I am seeing file transfer speeds between my HTPC and Iomega Home Media Network Drive of around 40-45 megabits/s, which translates to being too slow to stream content having bitrates of 30 megabits/s without stuttering. In contrast, the Drive gets about 80 megabits/s LAN connections.
Right now I have the following. I am unsure about the topology, since I didn't do the initial wiring, but I understand the central distribution point to be #1. In locations where there are both MoCA and non-MoCa devices (#1, #2, and #4) I use diplexers to split the coax to reduce insertion loss (the speed issues predated the diplexers though).
1. Upstairs location WRT400N router connected to the cable modem via it's uplink port. SIP adapter is connected to lan ports. Iomega network drive also connected to router LAN port. Is bridged to coax network via HME-2200 connected to LAN port.
2.Upstairs bedroom with Tivo connected to NIM-100.
3.Office with Actiontec MI424WR in bridge/switch mode, providing MoCA access via the coax port to printer and computer connected to LAN ports.
4. HTPC and Tivo on the first floor bridged to MoCA network with MI424WR router in bridge mode ala #3.
I've tried switching out different devices without noticeable changes (10 percent at most).
I'm trying to stream 30-40 megabit/s content between locations 1 and 4, but get significant stuttering.
I understand that some people have improved performance by increasing their TCP/IP receive window, but it doesn't appear that Vista or Windows 7 allow it to be manually increased. Most of the posts related to hardware connection issues involve people with no connectivity at all.
I'd be interested in hearing any suggestions or anecdotes about improving performance for MoCA networks.
