Internet speeds seem fine. The online bandwidth meters indicate I'm getting the rated speed for my service.
If I copy a large amount of data >100 GB (video files) over a home network the file transfer starts at 6-15% network utilization (1000bps NIC) then after 10-20 seconds drops to ~1% then to a fraction of a percent and rarely recovers.
On the network I have 2 XP Home and 2 XP MCE2005 machines plus a Win98. 2 XP machines are gigabit 1000bps NIC all the others are 10/100. Connections are through either a Netgear FVS318 10/100 or GS105 Gigabit router/switch. All except 1 machine can maintain 60-80% network utilization during the same large data transfer.
I've tried different cables, routers, NIC settings (1000bps, 10/100 auto negotiate, half duplex, TCPOptimizer)
It all comes back to one machine;
X2 240e Athlon, Gigabyte GA-880GA-UD3H mother board with integrated RealTek Gigabit NIC, integrated ATI HD 4250 graphics and 2GB of RAM. I'm running Win XP Home SP3 with all the latest updates.
This machine was a fresh load XP SP2. After the load the network was slow so I updated to SP3. still slow. Then updated the NIC drive to the one from MS updates. The NIC refused to work. Reinstalled the older driver from RealTek and the NIC worked but file transfer was still slow.
I then updated XP to all the latest MS updates (minus the NIC update) and the home network stopped working altogether. After some internet searches I discovered that the IRPStackSize parameter was missing altogether. I can only assume the updates messed something up. I manually added that registry entry and Home networking was up again but still slow.
I've run Malware and AntiSpyware checks, TCPOptimizer and found nothing.
I'm at my wits end.
