I have a SSD drive with Win 8.1 and all is well with internet access.
Then I installed XP SP3 on the old HDD. But this new installation cannot find my fiber connection to the internet. It says there is no Ethernet Card.
But the internet works perfectly with win8, and earlier XP also had no problems - plenty of internet. (I have a 50/50 fiber connection - always open).
What can I do?
