I have a related problem and all suggestions are welcomed.
Last week during a storm, my ethernet connection died. The PC (XP) was OK in all aspects except I lost my ethernet connection.
I purchased a new PCI board, installed and the Device Manager recognizes the device; however I still cannot access the internet and the YELLOW warning sign is imposed on the device manager and indicates it “CANNOT BR STARTED”
I have uninstalled and reinstalled as well as downloading current driver.
Using my netbook so any suggestions are welcomed - thanks y’all!
Do other computers work on your router? Netbook on that same router? If so - then the motherboard PCI bus may damaged - try several PCI slots ...
