I have dell optiplex 390 with windows xp.
I have a test machine that i have to have linked to an ethernet port and also have to have ethernet port for internet. The only expansion slot on my pc is PCI-e. I tried using a usb to ethernet adapter but it failed as it only worked for about an hour. I purchased a trendnet TEG-ECTX adapter and was unable to get it to work. When i install the driver software, it says "Do you wan to completely remove the selected application and all of its features?" if i click no it responds "sorry, you must remove REALTEK Gbe & FE Ethernet PCI and PCIe windows nic driver before installing this package.
Someone else tried it by clicking yes to the first question and after installing driver software neither ethernet card works...
system windows xp
i3-2100 CPU @ 3.10 GHZ
3.09 GHz of RAM
If any one has info please help.
