No internet connection

Question

Under Network and Sharing Center I show a red X between my inspiron 1520 to the internet wireless router (netgear 802.  I am begining to suspect the card in the laptop as I have checked everything and switched it out with a working desktop using the same cables and router. Running the device manager shows a yellow exclamination on my 6to4 adapter. So I removed same and reinstalled and reset netsh winsock. Rebooted and checked adapter again with the same ugly yellow symbol. Still cannot get on line with the laptop, anything just short of using it for a boat anchor will suffice. Thanks in advance Jack

disable the 6to4 adapter.  systematically troubleshoot your wireless connectivity.  power router off then on.  recheck ssid and turn off security.  turn off software firewalls, etc.   once you establish connectivity turn on wpa and software firewall.

I disabled the 6to4 adapter and rechecked everything else but still cannot connect to the internet. The Windows Network Diagnostics says to restart the DHCP client service. I have seen this before and not paid any attention to it. What is it? I thought someone told me that it would reset it's self on a restart.     Thanks in advance,  Jack

go into administrative tools, services and find DHCP Client service and try to start it.

Attempted to start  the DHCP client and got the following:   Windows could not start the DHCP Client service on Local Computer. Error 1068: The dependency service or group failed to start.

I have the exactly same problem. I hope I can find solution to this with your help...   I suspect that Vista is to blame.

Have you tried to connect the laptop to the router with ethernet to get a working connection?

Have you recently reinstalled your OS

If you are still having a bang on the adapter either the adapter is bad, or you might be usind the wrong drivers. As long as you have the bang it will not work

If you have recently reinstalled your OS there is a certain order to driver reinstalltion.

Jamaga_2000 · Answer

No, the os has not been re-installed, the router we are using is supporting two other desktops with no problems and we have tried an ethernet cable from the laptop directly into the router with no success.

you may have a corrupted file...   would try and run sfc /scannow from command line

Jamaga_2000 · Answer

Could you explain a little more. Like step by step please

xcator · Answer

run sfc /scannow  from command line   http://en.wikipedia.org/wiki/System_File_Checker

Jamaga_2000 · Answer

It says... You must be an administrator running a console session in order to use the sfc utility.

xcator · Answer

type cmd.exe in the start-->search box. when cmd appears, elevate it by right-clicking and choose Run as Administrator

Jamaga_2000 · Answer

That is the answer! I must have had a corrupted file because after running that sfc scan it repaired its self. After the reboot it went right on line. It did tell me that there were some files that it did not repair but I did not understand how to display them.

Thanks for sticking it out with me..........THANKS AGAIN
