Hi, everybody. Thanks for reading and giving support to newcomers. It would be highly appreciated. I have set up several networks using linksys gear with no problems so far. However, this afternoon I tried to set up what seemed to be a quite simple network: one cable modem, a linksys gateway/router WRT54G (v5 I think), one wired PC running WXP pro and another PC running XP Pro, wireless conected. Well, I set up the router as always, withour running the supplied CD. I set up IPs dinamicaly, WPA wireless security and both computers got to Internet without a hassle. Problems arised when I tried to share some folders and a printer among them. PC A, wired connected to the router, was able to ping PC B (wireless connected) and reach to the shared folder in PC B. However, PC B failed once and again to ping PC A, and of course was unable to access the shard folder and the printer connected to PC A. Both PCs are reaching Internet normally. Another strange behaviour was that the router hanged twice while accessing web config. pages on 192.168.1.1 after saving changes. Could it be a defective router? A configuration error? Your help will be much appreciated. Amando.
