Internet not working after reinstalling Windows 7

[KapteinFruit]

I reinstalled Windows 7 today and when I was done I can't get the internet to work. I got the LAN drivers installed and I've Googled about it, but I can't figure out what it was. I've tried restarting my router as well. I've also tried that new IP thing. That didn't work either. The internet worked perfectly fine before I reinstalled and it works perfectly fine on my laptop. Any suggestions?

have you installed the mobo drivers?

 

[Youngie1337]

have you installed the mobo drivers?

My thoughts exactly, need mobo drivers installed also.

Is the network card detected at all?

 

[AMDFTW]

are the 2 lights on when you connect the ethernet cable?

have you installed the mobo drivers?

Yes I have, I forgot to say that.

My thoughts exactly, need mobo drivers installed also.

Is the network card detected at all?

Yeah, the mobo drivers are installed, but how do I see if the network card is detected? I read about it, but didn't understand how to find it.

are the 2 lights on when you connect the ethernet cable?

Yes, they are.

Sorry for late reply, guys. I was a dog sitter.

device manager>network adapters

device manager>network adapters

Yeah they both (both internet ports) showed up.

Run the ipconfig command on both the laptop and desktop and post the results.

Start > type cmd and hit enter > type ipconfig

In command prompt, type in Ping www.google.com

How many packets are sent, received and lost?

If all four packets are sent and all four are received, you have connection to the internet its just you need to tweak your network settings.

You can check the following settings:

Got to Control panel > Network and internet > network and sharing centre > change adapter settings > right click on the local area connection that you are using and select properties > select internet protocol version 4 and click on properties > make sure the 'obtain IP address automatically' and 'obtain DNS server automatically' are selected > click ok and do the same for Internet protocol version 6 > click ok.

Tried reseting your router?

If you enable DHCP server of your router, you actually don't need to define any IP at the adapter.

Assuming you're on DHCP:

1) Check physical connectivity using control light on NIC and router for the port in question (as you obviously already did)

2) Check layer 3 (IP) connectivity to the router

Client and Router's LAN IP configuration should be correct. They need to be in the same segment. Otherwise your devices can't see eachother in the network without IP helper objects - which you don't use at home, usually.

your router could for example be (class c example):

192.168.0.1

and your client:

192.168.0.3

should your IP-address still be something like 169.xxx.xxx.xxx - which is an windows autoconfiguration address - you should use the following command in your windows cmd shell:

ipconfig /release

ipconfig /renew

as a result your NIC should show an adapter provided by your DHCP service (router).

3) Check physical and layer 3 connection of the router to the internet

as a subsequent action - assuming your client already has a correct IP address - would be that your router lacks at least layer 3 (IP) connectivity. your router most likely does have some sort of web management interface where you can check internet connectivity directly on the device. usually a page called "status" or something like that.

Edit:

Few routers' firewalls feel spoofed when devices connect in the DHCP IP-Range but are no DHCP clients.

I'm so confused right now. I have no clue what to do. So many big words

I have no clue what the guy above me is talking about :S

 

[BaMb1N0]

yeah, i'm sorry. can't help myself.

do you know how to check your pc's IP address? if yes, what is it?

In sort, in Command prompt type:

ipconfig /all

If you can see IP as 0.0.0.0

then type

ipconfig /renew

If this doesn't work, then try to go to 192.168.1.1 in the browser where router interface should come up if everything running at its default.

Default username should be: admin

Password should be: admin or 12345

Try these tricks & post the result.

Thanks for sticking to this thread even tho I'm horrible at replying. I'm at school so I can't check yet, but I'll check ASAP when I'm home from school.

So I tired to do what I was told, but it doesn't seem like anything of use comes up. With the "renew" part it just says "No operation can be performed on Local Area Connection 2 while it has its media disconnected." WTH does that mean? I've also tried reinstalling Windows after I started having this problem, but it didn't help at all.

one of your at least two adapters does not support the command. could also be a VPN adapter or firewire device.

- try to find out the name of your ethernet connection (simplest way for you: go to network and sharing center in windows 7, click on "adapter settings" on the leftern side (not sure about the name though because my system is in german). you will then see all adapters listed.

- type ipconfig /renew xy* (where xy stands for first two letters of that ethernet connection's name)

the system will then only renew the ip address of the chosen adapter.

Both the connections are called Local Area Connection number something. And another thing to inform about, when I use my gaming PC which got the internet issues, the internet on my laptop goes mad as well. It becomes so slow it hangs up on Skype and such.
