Can't access to the internet. Only option is to use a system restore of the previous day.

[vendetta041990]

For some reason I can't access to the internet with our main computer that is connected via a wifi cable directly connected to the router. If we use a system restore back in january 10, it's all okay (this happened back in january 11 when we can't access the internet at all).

After doing the system restore, if we shut down the computer and turn it on again, we can't access the internet again. So everytime we open up our computer, we always have to do the system restore from back in january 10.

Any help on this?

1. wifi is wireless. you mean ethernet cable 😉
2. run: cmd and ping command to 8.8.8.8

if you will see response then your problem is with DNS. -> google fix dns windows.
if not then your windows downloads some shit that breaks cables.
GET to your adapter manufacturer site and download drivers.

Being able to ping 8.8.8.8 doesn't mean it's a dns issue since seeing a response would work regardless if you had a dns server available or not.

Pinging a site by its actual IP address quite literally does not use a dns server.

In fact, I can set my dns to a random IP address and still ping 173.194.200.139 successfully, a ping of google.com of course fails.

DNS simply binds an IP address to an easier to remember name, like google.com versus 173.194.200.139

A more definitive way to solve this would be if you could ping 173.194.200.139 but you couldn't ping www.google.com

if you can ping but cannot access internet its either DNS or firewall.
if returning few days back works then its not firewall settings, if no windows update that destroys stuff. Firewall problems would require advanced settings inside network and some IT guy managing it.
so just by pinging 8.8.8.8 you will know all you need. And about your solution. I dont know 173.194.200.139 and I'm not sure if no answer from this is no network locally or just stupid random IP. 8.8.8.8 should be pingable from all over the world. And if you can access 8.8.8.8 but no network works its 100% DNS problem

Whoa slow down guys. Yes you can ping 8.8.8.8 or an actual website like www.google.com. I guarantee the www.google.com won't work if he can't access a website via a browser. It's a quick check while troubleshooting but let's step back and look at the problem. And actually you want to run "ipconfig /all". This will return your IP and tell you if you are getting a good IP from your router such as 192.168.2.x. But lets look at the basics first.

Do you have another computer, tablet, or cell phone you can use to check the internet? Does it work? I assume it does since you set a restore of a previous date and it fixes the problem.

It could be some software that messed up your ethernet tcp/ip connection in windows. Anti Virus, Virtual Private Network, etc.... First thing you want to do is double check your cables and make sure they are connected all the way and the LED lights up on your router. Log into your router through the browser with 192.168.2.1 or whatever IP your router uses and double check that your router is connected to the internet. If you have a second computer/phone you can double check this way instead of logging into your router.

Next go to Network Settings in windows. Go to change adapter settings. You should see your ethernet adapter and it might have a red X through it indicating it is not connecting. Click on it and choose diagnose this connection. This often will have windows repair the tcp/ip connection and get your internet working again.

You basically want to get your connection working under change adapter settings in Network Settings. Assuming your router and cables are all good it's a problem in Windows. As a last resort you can uninstall and install the latest drivers for your ethernet on the motherboard and see if that helps. Download it from the motherboard manufacturers website. It could very well be that the ethernet is just malfunctioning but I doubt it since a restore solved the issue.

Try to troubleshoot and get back to us with more info.

Hello all. Sorry for the long reply. Been busy with work. We can access the internet using cellphones, laptops and the other desktop computer we have. Really the only problem is the one desktop computer which is directly connected to the router is the one that has the problem. So we tried shutting down then opening up the computer again to test if it still can't access the internet so we tried your suggestions:

So we tried to "ping 8.8.8.8" and this is what it showed:
--------------------------------------------------------------------------------------------
PING: transmit failed. General failure.
Ping statistics for 8.8.8.8:
Packets: Sent = 4, Received = 0, Lost = 4 (100% Loss)
--------------------------------------------------------------------------------------------

we also tried ipconfig/all
--------------------------------------------------------------------------------------------
Host Name:
Primary DNS Suffix
Node Type Hybrid
IP Routing Enabled No
WINS Proxy Enabled No

Tunnel adapter Teredo Tunneling Pseudo-Interface:
Media State Media disconnected
Connection-specific DNS suffix
Description Teredo Tunneling Pseudo-Interface
Physical Address
DHCP Enabled No
Autoconfiguration Enabled Yes
--------------------------------------------------------------------------------------------

We also checked the Device Manager and to Network Adapters which is a Intel(R) 82579V Gigabit Network Connection which has an exclamation mark on the icon and it says that "This device cannot start (Code 10)".

Under System Devices Intel (R) Management Engine Interface also has an exclamation mark on its icon.

So far this is the only findings I could find..

Any help on this guys?
