Wireless connected but cannot access w.eb...

Dell / Inspiron 600m
September 21, 2010 at 17:08:50
Specs: Windows XP, 512mb
I have 3 computers and a Linksys WRT54G router. PC1(desktop) is connected to the router via cat5 Ethernet cable. PC2 and PC3 are laptops connected via wireless. I recently got the third laptop and ever since I connected PC3 to the wireless network I have had issues with PC2. PC2 is a Dell Inspiron 600m with Windows XP home edition sp1. (it is only Service Pack 1 because I recently reformatted the computer as a last act of desperation before posting here.) It says it is connected o the network, but I cannot browse the web or update any programs. I can ping 127.0.0.1, 192.168.1.1(Linksys Router), 192.168.1.100 (the IP), but not any other computer on the network. I will paste the ipconfig /all for PC2 below:

I have been trying for a two weeks to fix his so I can continue my online classes so any help would be greatly appreciated. I will also paste the ping stats as well below for reference.

What in your network is 192.168.1.102 or 103 or 104 ?
Those are listed as your DNS servers. I would have expected the router 192.168.1.1 to be set as primary DNS. In my little network I have set the secondary DNS as the default one provided by my ISP
You note that your ping to 192.168.1.104 failed

I have my router settings under DNS server there is an option for Static DNS. there are 3 slots and i put in 192.168.1.102 - 192.168.1.104 in hopes it would help. I am sure if i took it off it would revert back default.(192.168.1.1). However I don't see how that would change much since PC1(desktop) and PC3(recently added laptop) still have no issues with the network.

Do not put those IPs in the router WAN DNS configuration. They do not exist in your network. Your ISP should have a default DNS Server that you would use. If it will not autoconfigure then call your ISP to obtain the details for manual input. Once this is done you can leave the second and third DNS server details blank.


Then in the client systems configure them to "Obtain IP and DNS automatically.

Then reboot everything.

The client PC should then show 192.168.1.1 as default gateway, DHCP server and DNS server when you run ipconfig /all again.
