WiFi BTing sucks

I used my chessy old P3 Compaq Presario 1720US notebook to access as a BT station using WiFi. I tested it for 3 days, and, well, it sucked big time. Most big (300M+) download failed. ONly the small files work. I am now copying all the temp BT files back to my home machine and continue BTing there instead. Seem like my P3 laptop is no good for anything but a simple thin client.
