Home Internet not working on one computer

We just reset our home Linksys router because we forgot the password. We set it up fine using WPA2. It worked immediately on all computers.

We have one Vista laptop. When we first set up the reset Linksys router, this Vista laptop did work. It connected to the WAP and got Internet.

Now, though, it doesn't. It can still connect to the WAP, but connection says local only. I run IPCONFIG and it has all the settings (default gateway, ip address, dns servers), however I can't even ping the default gateway (so the linksys router).

Any ideas?

rjantonelli - MAC filtering is disabled on the router, so that wouldn't help.

cbmm - There is no firewall running and I have done what you recommended several time and always get the same result

cbmm

please run "ipconfig /all" from a command prompt and post the results here.

Is the network set to public on the Vista laptop?

Following the following instructions to check and change to home (note even it if it is public it should work):

Ok...

conuladh - it is broadcasting on Auto. I can't change it in the router console - that is the only option it gives me. Also, I have tried to configure the home network as both public and private and netiher works

k wilke - I disabled ipv6 on the wireless interface and that did not fix the problem either

cbmm - i can't give you the output from the problem pc..becuase it has no internet for me to be able to post it here. Here is the wireless interface portion of ipconfig /all from a computer that is working though....if that helps..

oh, and about the ipconfig output, the problem pc gets the same output, except with different IP (it is 101) and that there is no ipv6 configured.

everything else is the same. it has defualt gateway, dhcp and dns servers.

still can't ping default gateway!!

Marius Gunnerud

are you using static IP addresses or reserving IP addresses?

If you are, I would double check the reservation or static IP, the subnet mask, dns, and default gateway to make sure it is correct.

If you are not, have you done ipconfig /release and renew?

issue the ipconfig /flushdns command

Have you done a diagnose and repair on the network connection on your Vista machine?

Marius Gunnerud

also are there any errors or warnings in the event viewer that might point to this problem?

Marius Gunnerud

are you able to ping any other devices on the internal network?

Hi - we called linksys and they ended up doing so CRAZY configuration on Vista. It took about an hour for them to go through it all. Thanks everyone
