If anybody can help me with this please help. I have a MS pci adapter model number mn-130 and a 14' crossover cable connected to my xbox. The speed of my network is 100 Base T Full Duplex and when I look on my xbox it has the same thing showing so I know I am connected at the right speed. I use flashfxp and when I transfer a file it transfers at 10 kbps. It took 7 hours to copy a file that was 60mb. I have talked to MS and they can't help. I had another network card and talked to them and they couldn't help me so they told me to get a new card so I got the MS one and have the same problems. I was able to access the xbox through MS networking and copy files through windows explorer but they still only copied about 10 kbps. I am at my wits end and don't know what to do. Someone please help me. I have looked at the networking guide on this site and tried all the things to try and speed it up and nothing works.

Assuming you are POSITIVE the ethernet cable isn't damaged, make sure you dont have the cable running next to any high-power sources, or anything that might emit disruptive frequencies like flourescent lights and power lines inside your wall. I used to have bad packet loss when my ethernet cable ran next to my Uninteruptable Power Source (aka Battery Backup).

Good luck.

I just exchanged my cable for a new one and I am still having the same problem. Does anybody know what else it could be.

take a look at the tutorial in my sig. There is a section that has some suggestions for you to try to troubleshoot speed issues.
