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?

Sounds like the MAC address may not be listed correctly in the Linksys web interface.

Open command prompt> type in ipconfig /all

You will see tha MAC address.i.e 00:9F:00:56:0E:0A

Make sure it is correct in the filter list.

I would start by disconnecting from the wireless networks--go to network and sharing center--click on manage wireless networks--remove all wireless networks listed. Restart the computer and join the wireless network again. If this doesnt fix, there must be a firewall on the a pc that is blocking communication. You may need to add the network to a trusted zone in the firewall, that is if you have a  third party firewall installed.

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

What channel is the router broadcasting on? Channel 1 causes me problems on a couple of machines, regardless worth changing channel number by 3 as a test to rule out conflict.

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

Marius GunnerudSenior Systems EngineerCommented:
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
