Hi,
Thank you for looking. I'll try and let you know everything I think that you will need. I have an HP pavilion dv2000 laptop running windows vista 32 bit, with a broadcom 802.11b/g wan and a Nvidia nforce network controller. I have verizon fios broadband, with verizon's ultraline series 3 modem and router.

The problem that I am having is that the computer randomly, or seemingly randomly, losses the internet connection. It changes to a local only connection. However if I am streaming video or audio it will continue to stream, but I cant open websites. As wierd as it sounds it seems as though the computer stops recognizing the internet although it is still actually connected The only way I can see to fix it is to restart the computer, as I tried to reset the router, reset the wireless card, disabling the TCP/ipv6, windows diagnostic, and just waiting it out . This started happening about once a month but is getting worse and now happens about every two days. It doesn't just happen on my home wireless router but it has also happened at my parents house, in laws house and at school. If after it loses the internet wirelessly and I connect to the router with a wire it still will not recognize the internet. I have been trying, unsuccessfully, to get help from HP but they are not understanding what is happening and are just blaming the ISP. But this doesn't explain the fact that I have another laptop and a desktop hooked t0 the same router and they are fine, along with the fact that it happens at other locations.

I Posted this on another forum and this is what was recommended which did not fix the problem(view here http://www.geekstogo.com/forum/Laptop-rand...on-t242251.html ):
-assured dhcp was enabled
-deleted connection profile
-disabled hp wireless assistant
-disabled ipv6
-reinstalled network adapter and updated drivers



Thanks for your help and hopefully this makes sense. Let me know if you need any other information.

digitalocksmith,
I have the windows vista firewall running but I am not sure how to find out if it is the problem. I have checked to make sure that it recognizes the LAN and wireless connection.


Here are the results of
ipconfig /all > C:\results.txt
route print >> C:\results.txt
ping 127.0.0.1 >> C:\results.txt
ping google.com >> C:\results.txt
ping 209.85.171.100 >> C:\results.txt

Are you using VM Ware or Virtual PC?

Just establishing the reason for your tunnel interface connections listed in IPCONFIG......If you are, and you want to continue running this software then these connections need to remain.

It may also be a result of activation of TCP/IPv6 Teredo Tunneling in Vista.

To disable Teredo in Vista run through the steps outlined below and see if connection issues improve.

Disable windows firewall whilst trouble shooting just to be sure......make sure no firewalls exist in any AV security suites you may/may not be running (ie AVG or Kaspersky).

digitalocksmith,
I am not running vm ware or virtual pc. I disabled TCP/IPv6 Teredo Tunneling in Vista and windows firewall, should I wait and see if it still loses connection? Thanks for your help.

digitalocksmith,
Sorry it took me so long to get back, I have not lost connection since the changes. After a few days I decided to put the firewall back on to see if it was the problem and it still works fine. It must have been the TCP/IPv6 Teredo Tunneling in Vista. I am extremely excited as constantly loosing the internet was driving me crazy and made me not even want to use the computer. Thank you very much for your help.

Matt

well unfortunately It happened again today. It took a long time as usually it was happening every other day. I have been trying to think back to anything that i may have done or changed but cannot think of anything.

edit: The laptop is currently sitting in its unconnected state if you would like for me to check anything. thanks

Matt

Hmmm....the only thing I can see that you haven't tried is uninstalling the device from Device Manager and from the Add/Remove programs. Reboot and reinstall the drivers and software.
