i have connect two pc (wired) through prolink wireless router. The two pc can connect to internet. One of the pc - XP, it cant see itself on his own my network place and also try to ping own ip address also no reply. Once try to ping the router address, it got reply. Pls help. Is it the window problem?

it sounds like u might need to enable file and print sharing on both pc's...assuming that the other pc is a windoz based machine...re: pinging the machine, try pinging 127.0.0.1 first and see what happens there

yap, i already enable the file and printer sharing. Its still same. Try to ping own ip from original pc still no respond. Jus router and the other pc got respond.
