How to use sneakernet to fix internet problems ?

[MetalHeadm/]

i have 2 computers and one was recently fixed for me but now it wont show me that any internet connections are available. How can I use my working computer to help resolve this issue with my other? A friend told me to use sneakernet, but if there is another way then that would appreciated as well.

Reinstall the drivers for the network card and the motherboard by downloading them on one computer and then sneakering them over to the other.
