Hello loving supporting fellow list members, For those who just returned from a black hole, here's a recap. I've written a replacement driver for the Realtek 8139 type of cards. After it has been plagued by some strange errors (due to me), it's now in a state of working. Or so I thought. The final problematic problem is that the whole process slows down enormously when you receive large packets. For example, if you open a website, and after that do a ping, times will be disastrous (not to mention the amount of packets that get lost). Why is this, you ask? Beats me. That's why I'm hoping that someone else sees my huge bug, and helps me fix it. I'm desperate. Really. Okay not really, but a little. Niels Sascha Reedijk
