I have a Linksys WRT54G router. 2 my laptops are running Windows XP Service Pack 2. Router configured as follows -SSID BROADCAST DISABLED -WIRELESS MAC FILTER ENABLED - Permit only PCs listed to access the wireless network (2 MACs entered) - PASSWORD CHANGED Despite all these configuration steps network considered as "UNSECURED WIRELESS NETWORK". What to do to make it secure? Thank you. Eugene.
