Is there a hotkey to enable or disable this device?
I can't find any key for that?
How would it look like?
Do you mean a keyboard key?
The data I can find on the machine indicates that the ethernet is on a mini-PCI card, which can certainly be replaced. And replacements can be bought. Have a look here:
Mini-PCI stuff is usually easy to change, once you work out where it is. There will be the card, and there will be two small plug/sockets, which connect to the modem and ethernet socket on the outer case of the machine.
In case I would have to go the replacement route,
---is it sure that I can get it working in Linux?
---which driver would I need?
---would Windows still recognize the replacement card?
---is it easy/save to open the laptop case?
I have to confess, I'm a bit nervous to go that way, but I think I'm getting closer to solve the issue HELP please!
