Having a problem connecting to network from home office with Sony Laptop with MS XP. My tower PC works and both use ethernet network card. On the Laptop get a limited or no connectivity. When I check the LAN, It's connect, and it sends packets, but does not rec packets. I was using the USB port to connect with my old ISP. But the new ISP data set does not a a USB slot. Seems that after I started use the USB port, it cause a problem with the ethernet port.
