DLink 10/100 NICs transfer fast after unplugging?

I currently have two PCs using DLink 530TX nics (10/100) hard-wired to a Linksys WRT54G router. For some reason, everytime I restart one of the PCs, transferring files between PCs is extremely slow. However, if I manually unplug one of the PCs (network cable) and re-connect it after a few seconds, the connection is much faster, about 8mb/sec (which is acceptable). Is anyone aware of what could cause this?

Thanks in advance.
 
1) Very strange. Make sure you are measuring in MegaBITs (Mbs) and not BYTES (MB). That sounds like a firmware or a speed/duplex mismatch problem (which is why unplugging and plugging back in makes a difference). Homemade cables, that could cause it as well.

2) The 1000 Base-T nic will make no difference, it will negotiate to 100/full with the switch. There is also nothing theoretical about 100 Base-T - it's datarate is 100 megabits, the throughput doesn't change whether it's 100 or 1000.
 
Thanks for the response.

Yeah, it's odd. Both are the same NICs and set to auto-negotiation. I believe I've tried different cables in the past as well, would be one of the first things I'd do. As an example, if I'm tranferring a CD image (700MB or so), at first it would say "140 minutes remaining", then after unplugging and replugging, it would be about 2 minutes. I've never touched the firmware for these nics, and driver is the default WinXP driver.
