Comment: I am trying to add a Dell laptop (Pentium 2; win2k) to my wireless network using a Linksys Wireless network adapter to link to an Actiontec DSL Modem/Router. The Linksys adapter reports it is connected to the Router, but there is no internet connection. Trying ipconfig/release gives a reply of IP Address for adapter Local Area Connection is already released. Trying ipconfig/renew gives me the following message: "DHCP server unreachable." ipconfig shows the following DHCP enabled Yes
Autoconfiguration enabled Yes
IP Address 0.0.0.0
Subnet Mask 0.0.0.0
Default Gateway
DHCP server 255.255.255.255 The router is functioning, by the way, and is providing access to the internet for two other desktop computers. Any help greatly appreciated.

Reply: (edit)Try assigning static IP info to the wireless adapter and see if it works that way. How many IP addresses is the DHCP in the router configured to allocate?

Reply: (edit)If I understand your suggestion, I have went into Network connections and in the properties section of the tcpip component have tried both obtaining the IP address automatically and specifying the IP address. Doing the latter shows a specific ip address on the Linksys info screen, but disables dhcp and I still don't see the internet, though a connection to the router is still indicated. I'm not certain of the answer to the question about the number of IP addresses but believe it to be far in excess of the three it would have if the laptop were connected and functioning.

Reply: (edit)OK. What IP address information did you try when you assigned it statically? What is the IP address and subnet mask of your router? You say that it displays this info in the Linksys info screen.... did you try going to DOS and doing an ipconfig /all to make sure that the NIC actually took the settings?

Reply: (edit)I used 192.168.0.1, which is the address for the Router and the subnet mask 225.225.255.0. Doing an ipconfig shows this information as the IP address and subnet mask.

Reply: (edit)Following up on the last post, I re-entered the IP address as 192.168.0.6 since the desktops on the system are .2 and .4. I also added a default gateway address of 192.168.0.1. This is confirmed doing an ipconfig.

Reply: (edit)Can you ping the gateway address of .1? If not you have a hardware issue that has to be addressed first.

Reply: (edit)Also try pinging loopback, which is 127.0.0.1. When you assigned a static IP address of 192.168.0.1 to your PC, you gave it the same IP address as the router if I understand you correctly. After confirming this with ipconfig, it makes me believe that there is indeed a hardware problem because you should have received a message telling you that 192.168.0.1 is already in use on the network. When a computer either receives an IP address from a DHCP server or has a static address, the computer sends out what is known as a gratuitous ARP. It is a test to make sure that it is the only host on the subnet with that IP address. It sends out an ARP request asking who has the IP address of the one it was assigned via DHCP or static. If no other host responds, then the host knows that it is the only one with that particular IP address and all is well. If another host responds and says "hey, I have that IP address", you should be alerted telling you that there is an IP conflict on the network. Since you did not receive this error, it makes me believe that there is a hardware issue.

Reply: (edit)Thank you for the information. Can I assume the hardware problem is the Linksys USB network adapter since the other two desktop computers function perfectly well with the router? Or is there some other hardware on the laptop that might be causing the problem?

Reply: (edit)Are the desktops wireless or hardwired? If they are wireless, and functioning correctly, I would say it is an issue with your USB adapter. If they are hardwired, it is hard to say.

Reply: (edit)I've had similar problems before. I've found in the past it had to do with the communication between the router and the DSL Modem. For some reason the router caused the modem to log off. Linksys sends a setup CD. I would recommend rerunning that. It programs the router for communication with the DSL modem
