My internet works. Just want to get that out of the way.
Code:
Cable -> router -> Computer 1 (internet works fine)
|
V
Computer 2 (internet suddenly doesn't work)
When I ping router from Computer 2, I get "Host unreachable." It could be a problem with the RJ cable to the router and it could be a problem with a faulty network card. The card was installed a few years back and is somewhat loose.
How do I pinpoint the problem to one of these two? Or something else, really.
Btw, the cable is long and span three stories - I am rather uninclined to move it or attach it to another computer
Jam it back in, in the dark.
