I am having a pc and laptop. I was coonecting them both witj crossover
cable and could transfer files etc. Today I am unable to ping laptop
from pc and vice versa. But yesterday I have installed irda utils
and bluetooth in laptop. Can ts cause this problem. I am having
guessnet to select network in my laptop.
