I am working on a small network for a local business. I previously installed a AP linksys wireless router with 4 port LAN (wrt54g I believe). The access point is connected to the internet by its internet port. The original installation had 2 wired PC’s to the AP and one wireless dell laptop using WEP encryption connecting through the wireless. All worked well. All of the PC’s where XP machines with SP2. All PCs have their own assigned IP Addresses: AP 192.168.1.1 Wireless router with 4 ports LAN PC1 192.168.1.2 Personal Computer, XP, SP2 Hard Wired to LAN Port 1 PC2 192.168.1.3 Personal Computer, XP, SP2 Hard Wired to LAN Port 2 Laptop 192.168.1.4 Wireless WEP Recently the customer wanted an older PC connected to the network for Internet browsing. It is and older dell machine using Millennium OS. I installed in one of its USB ports a Belkin wireless adapter. During setup of the belkin USB adapter it did not allow for WEP encryption, only WPA. So I had to reset the AP router to WPA, I assigned it an encryption key and set it to use the TKIP. I then set the Millennium Box to the same encryption type and so forth to match that of the AP. I also did the same to the Wireless Laptop. The problem that I am having now is that I cannot reach the internet through the Wireless machines; they both are able to connect to the wireless AP and have a good connection using the WPA encryption. I did a ping from them to the AP 192.168.1.1 to know avail. I cannot get through. The other two PC’s that are hard wired are reaching the AP and the internet. I have done all that I can think of, I need your help. Please reply.
