I recently purchased a WRT54G router and hooked it up to my home computer through ethernet, following the instructions on the install CD. It is running Windows XP. Our internet provider is AT&T's SBC DSL, which is PPPoE, so I appropriately set the connection type to PPPoE and entered the master screen name and password. The internet works fine on the computer connected via ethernet, but I also have a Windows Vista laptop (fairly new) which can detect the network and claims to be connected to it, but I cannot actually access web pages. I can ping the router but cannot ping, say www.yahoo.com. I also tried ipconfig /release and then ipconfig /renew. ipconfig shows that it appears to be giving the vista laptop an ip address (via DHCP). Here is all the configurations under ipconfig under the wireless stuff: Wireless LAN adapter Wireless Network Connection Connection-specific DNS Suffix: Link-local IPv6 Address: fe80:554d:4a2d:77cf:4608%10 IPv4 Address: 192.168.1.101 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.1 The IPv4 Address I am assuming is the IP address assigned via DHCP, as the other computer has the address 192.168.1.100. I tried SES under the router's settings and it didn't change anything. I just find it so stange that the laptop IS connecting to the router but not giving me internet access. If it helps, the modem is a SpeedStream 5100, and on the home computer (the ethernet connection), I often have to manually connect to the internet by going to "Connect To..." and then selecting the connection, under Broadband (dsl2). I'm not sure if this would be what is creating problems for the laptop, but it doesn't even work when the internet is up on this computer. Either way, it is claiming to be connected to the router even though I cannnot access webpages. I do not think it is a DNS issue, as I couldn't ping Yahoo's IP adderss either, and both IPv4 and v6 are set to get an ip address and DNS automatically. Any suggestions? Also, the modem is NOT currently set up into bridged mode, but I am assuming this is not necessary because the computer attached to the router via ethernet is getting internet. I did not do this because it seems like almost a point-of-no-return, because I do not know how to get a modem out of bridged mode without having to reset it. The default address for the modem is 192.168.0.1 while Linksys's is 192.168.1.1, so I wouldn't imagine that the conflict is there. I have read some people having problems that are solved once they put the Linksys CD in their laptop as well to install the drivers. However, I cannot figure out how to use the CD to install the drivers and am not sure if this is the problem or not. Also, all security is currently disabled on the router to better enable me to troubleshoot this.
