Problem of conectivity to other system after installing Linux
I had a window pc and it was working fine on network. I unplug the HDD and place a new HDD in that PC and installed Linux A S 3 on this pc. Installation was OK but after installation the only problem is that this system is not pinging to gate address or any other pc's on same network. Where as if I again use the old HDD of window, system networking again ok and I can ping other PC's from this system. Please advise me to resolve my this problem.
