My Dell 8200 with WinXP only connects to the internet about half the time on bootup or restart. I'm using Adelphia Powerlink with a Terayon modem. Adelphia says my network card has to be on IRQ 5, 9, 10, or 11 for their modem to work with XP. My card is on IRQ 18. Dell says the IRQ's cannot be moved or reconfigured. I've tried a 3Com and a Linksys card with no change. What is the solution here? Help!
