What had you been modifying when you realized you no longer had internet access?
Do you get an IP address from your DHCP server?
Can you ping anything? Local or Internet?

Click the start logo-->type "internet options" and hit enter.
Ont the Connections tab, click LAN settings button
You most likely do not need the Proxy server button checked. Some malware will check it for you and point all internet request inward

I try to download an anti virus upgrade. It ask me to reboot after install.
I reboot the machine, it no longer able to access internet
I did check off the Proxy in LAN setting and use 'Automatic detect settngs'

I try to ping 127.0.0.1, it works.
But I try to ping the router or address outside in the internet, no connection and said transmission failure


Here is the snapshot of the network connection

Try this:
open a CMD box

Run > cmd

On CMD

c:\>ipconfig

Check if you are getting any IP, if you see something like 169.x.x.x then you are not getting any ip address from DHCP (dynamic IP).

Now if you know your router IP Address try to set your IP address manually, if your router is 192.168.1.1 then put as IP 192.168.1.10 and mask 255.255.255.0, now try to see if you can ping your router. If this fails check your cable, maybe it got damaged.

Re-enable dchp on that adapter to see if it fixes it.
If so, do another ipconfig /all and compare the settings

Click Start Logo
type ncpa.cpl and hit enter
right click your LAN adapter and choose properties
find Internet Protocol Version 4 under the Networking tab, highlight, and choose properties below
change the radio buttons to obtain IP and DNS automatically.

If it doesn't fix it right away, try running the network troubleshooter, and/or restarting

Here is the connection status of wire and wireless.

I check the network adapter driver, all seems to function normally.

If you see you have the 169.x.x.x so the router is not giving you any IP Address. Try to set them manually.

But I have another few labtops all able to connect to my router except this computer.  I did use this problem computer in other location. No luck same problem.

cavagnaroCommented:
Maybe the pool of ip address that your DHCP server is configured to provide is full...if you have access to it maybe you can try to increase it.
Other option is to take the other working computers cable and plug it to this one that is having problems and see if it works.

cavagnaroCommented:
Erm...which AV are you using...try to disable it...maaaaaybe it is blocking all traffic even the DHCP request...

tommym121Author Commented:
Hi Cavagnaro,

I don't believe the DHCP server full. I have 99 entries and only use less than t0.  
I did try to use working computer cable just the same
I uninstalll AV (Norman Security).  It is still the same problem.  I did turn off the firewall.

cavagnaroCommented:
So, question, if you put the ip manually does it work? Disable DHCP request and put Ip address manually o test and see if you can ping your router

zkriegerCommented:
usually when i have issues like that, i uninstall the network card in device manager, reboot and let it redetect.

sometimes AV or firewall programs can disrupt the windows IP drivers and this reinstall usually sets it back to what it should be.

tommym121Author Commented:
Try all these no luck. And I try to reboot.  No luck.
Any other idea I should try?

cavagnaroCommented:
Is this a PC or a laptop?

zkriegerCommented:
check the port on the computer and see if any of the pins are damaged. I assume you have already tried a new cable.

tommym121Author Commented:
This is a laptop with Win7 preinstall.  I have used it for a month and have no problem.  I have used both wireless and wired. All work prior to upgrade the virus scan software.  I did uninstall it.
I am not sure what else can I check.

It seems like TCP/IP stack is corrupt. Try running this at a command prompt...

netsh winsock reset

If that doesn't work, try uninstalling and re-installing the NIC/WiFi adapter if you have not already done so.

We used o get this a lot with previous versions of Windows when uninstalling anti-virus/firewall programs. The uninstall somehow corrupts TCP/IP and/or winsock.

I try all you said. Still no luck! What can I do?

education-dynamicsCommented:
If none of the above have worked...maybe try system restore to when it was working, and try the uninstall of the AV again.
