I think it is a PCI adapter, however i am not sure how to check

motherboard would be a ASrock 775v88+

are all device manager entry's ok all drivers installed all the way down click on show hidden devices

in device manager under network adapter is:

bleutooth device (Personal Area Network)
bleutooth device (RFCOMM Protocol TDI)
VIA Rhine II compatible fast ethernet adapter

there are no errors related to the adapter in eventviewer

That motherboard has built in LAN port do you have a PCI LAN card anywhere you can install and try

you may want to consider a bios update for that board

all (also the hidden ones) drivers are installed correctly (well except for my audio driver, but that is off later concern)

i don't have any spare PCI LAN cards to install on my computer

could a bios update help with the internet connection (because it will be a lot of trouble since i cannot reach internet, and we don't have burners on the other computers)

yes it's very possible that a bios update could cure the problem however it would be easier to try another adapter if you had one for a quick test

why did you have TCP/IP V6 unchecked
