My desktop hadn't connected to the internet for a couple of days. Tonight I started troubleshooting and couldn't figure it out. I had network access; my router was giving me an IP and my gateway was my router. But I couldn't ping the router and couldn't get to the internet.
Then I searched and thankfully found your post! As soon as I read it was a McAfee bug I remembered that crucial email! Pasted below is a subset of the entire email, with the relevant portion for those of us who can only access the internet after -rebooting into 'Safe Mode with Networking':. Only problem is, that the speed is much less than it used to be with the Atheros card. I have updated the driver for Atheros and tried most other suggestions that I read in this thread, to no avail.
Still I have run extra online scans F-Secure, Panda but found nothing worse than adware which my Superantispyware would probably also have found. In device manager are now 3 Network adapters: 1. Atheros, 2. I basically followed your steps, unticked the IPv6 box, disabled my USB wireless adapter, re-enabled it back, and voila, working internet!
I am using Windows 7 and this happened a couple times in the past whereas the other computers in my house one Win7, one Ubuntu didn't exhibit any issue. I'm bookmarking this page for future reference thanks goodness for the internet and how it archives pages almost forever for people to use in the future. Seriously, I've scoured other forums but this thread is the best. I went to the Dell site. It solved my problem. That's the issue - they Windows 7 and McAfee were fighting each other in some form or another.
I have this problem 2. I read it all and done everything that was mentioned. Also tried doing the solution about McAfee. OMG I have had this problem for over a month and I could not make any sense of it considering that my Atheros ethernet card would network connect but not connect to internet. I would've thought the card was faulty or some other freak idea, but I was using it prevviously on ICS and it worked perfectly fine, as long as it wasnt plugged into my router and the internet was coming from a shared connection..
Now honestly that blew my mind and i have had a posting up on this topic for a while So i could not find any compatible driver software for the card, and i did notice that the hardware capabilities are not set and is the exact reason why the card does not work in windows 7 or 8.
So if anyone knows how to program the driver so the card does have some capabilities then it might work, but i do not know how to do that.. So now the really frustrating, but solvable, part is You can run a virtual system and boot Windows XP while still in the windows 7 environment which has not network or internet connection , and be able to connect to internet!! I just tried it and it works!!
Those of you who dont know One thing though, when you are setting up your virtual machine make sure to configure your hardware and set the network connection to bridged. Same problem after replacing the mother board on my computer. Switching the LAN cable from one port to a different port did the trick. My piece of junk computer has been having the same problem, but the worst part is it is intermittent, without me making any changes.
So how on earth am I supposed to troubleshoot when none of the known fixes work, and the problem arbitrarily arises and disappears as it pleases? Then I discovered that my computer is connected to the internet i. I could perform Microsoft and virus definition updates but all my browsers could not go online e. Once I discovered that, I ran the built-in diagnostic test and it was reported that there was problem with the DNS failing to respond.
Since then, I couldn't replicate that error message even by running the same test. Booting into Win7 in safe mode also does not make any difference - still cannot connect either to the internet or local routers.
Furthermore, IE10 fails to launch runs then just disappears quietly , even in its own safe-mode! I'm also unable to turn on 2 services in Avast.
What is wrong with the system and what can I do to resolve the above basically to get online to check my emails, etc? Apparently, I followed someone's advice to delete and restore a few registry entries related to TCPIP and Winsock and that solved my problem. Finally, the answer I hoped someone would post. Basically, found two answers but resetting Winsock seems to be the best. The other was to disable the Bonjour service but I'm sticking with the Winsock reset.
This is a Window issue. I have this problem on every other PC in house. With different hardware configuration different windows versions. This is just another stupid Microsoft thing. If you cannot positively detect that the network is connect to the internet, then just don't display anything and confuse simple users.
If you run the troubleshooter, he will tell you that there is no problem, you are connected to the internet, but it does not update the stupid icon. Typical Microsoft, they will write suggestions on how to fix it, but they don't bother to just update the software to fix the problem for good.
And I am sure this takes a programmer 10 minutes and saves system administrators globally thousands of hours of calming down their users. This should have become apparent when you ping www. I too have this problem. I can ping from the command line but unable to access the internet from any browser.
I had a virus snapdo which I hope has been eliminated using Malwarebytes and other virus cleaners. I WONDER IF many of the above proposals as solutions have worked simply because the action taken has disabled and then re-enabled the network adapter without this being apparent. I have an intermittent but annoying problem of lack of internet connection despite good LAN connection on startup of Win 7 across several different computers all Dell, some desktop, some laptop and versions of Win 7 and, in fact, using two different LANs on two different ISPs on opposite sides of the world.
It even happens that one computer will have the problem and another not on the same LAN. Equivalent situation never occurs on a machine running XP. It's just a nuisance which is why I came looking on this site for a "proper" fix. I connect to a VPN often.
Just changed it to "obtain automatically This resolved it. A USB wireless adapter has been installed along with its driver. With the wired one disconnected, attempts to connect the wireless adapter have resulted in it being "connected" but without internet access.
Both gave the same results. It also was not getting a DNS server address, so I set that up for 8. For some reason, I decided to reconnect the wired connection. This came online and was "connected" and had internet access.
Here is the really strange thing: once the wireless connection showed it had internet access, I unplugged the wired connection again and the wireless STAYED intact, continuing to have internet access. I could confirm that the connection was through the wireless connection by doing a speed test.
The modem that the wired connection was using was a substantially slower service less than 5 mpbs compared to nearly 30 mbps. I spent the last two days fighting this on a users computer and even went as far as wiping the machine back to factory.
I finally realized that no matter what I was always getting the same IP address. I had to hunt for it on one of our many DHCP servers but once I found the record I deleted it and now my problem is solved.

Monday, November 28, AM. Monday, November 28, PM. I have the same problem. Reinstalling windows or quickrestore does not solve the problem. Most things I tried didn't work. I think it may have come back on it's own. What I thought did work temporarily was disabling network adapter and reenabling it. We'll see how it goes.
Are you having problems connecting to internet in your Windows 7 Computer? Windows 7 can automatically fix number of problems relating to internet connection. The problem may be due to a problem in Windows 7, or may be in network set up or it may be with your internet service provider. Here are some solutions to rectify the problems related to internet connection in Windows 7.
Turn off Fire Wall or Anti Virus Programs : One problem why internet does not work in a newly installed Windows 7 is that of due to third pary firewall or due to anti virus. To make sure that the problem is not due to these, try to uninstall firewalls and anti virus programs.
If the anti virus program or the firewall is not compatible with Windows 7, then there is a possibility that it an accidentally block the connections to the internet. Disable protection mode : One of the other reasons is that you may not be able to connect to the internet due to IE8 which ships with Windows 7 itself.
It is believed that the security settings are set such that it is not possible to connect to the internet or any website at all.
This can be tested by going to Tools , then Internet Options , and clicking on the 'Security tab'. Click on Internet and move the slide bar down to t5he bottom lowest security as shown in the screen shot below. After moving the slider down completely, click on OK. Now close the IE8 and open it again. What's weird is that old computers that's still connected to these two "problem" switches are still working fine with full internet access. It's only when I try to connect a new device that I lose internet access.
Somewhere in the back of my head I remember that being an issue with certain NICs. Give it a try Can you please post your switch configuration? It could be an ACL blocking access to the internet. It's possible an ACL is applied on certain ports. Buy or Renew. Find A Community. Cisco Community. Thank you for your support!

How satisfied are you with this reply?
Thanks for your feedback, it helps us improve the site. In reply to Vijay B's post on September 26, Internet Explorer is my default browser, I also use Chrome, Firefox, and Opera There are no issues with the network itself and I believe it has something to do with the laptop itself. In reply to Need ComputerHelp's post on September 27, Hi, Did you make any change to the computer prior to the issue?
Method 1 This issue may occur if you rename or delete the profile. If the issue started recently, then I would suggest you to perform system restore to the data it was working fine. In reply to Vijay B's post on October 3, Thanks I ended up getting to be ale to work, I had to do a restore to previous settings, I did lose some documents, but now my computer works. Thanks for the help.
