the other day i've installed samsung PC program so i can put music and other files in my phone. after i restarted my computer my internet stopped working. i uninstalled the samsung program and it's still not working. The router i'm using says that its working but its not. i checked my brother's computer and the internet is working and his wire is connected to the same router. i tired system restore but that didn't work. i tried moving the wire to another socket and i tried repairing and disable/enabling the connection but all that didn't work.
