Help!

[Albert147]

Hey,

 

I just finished building my computer and after successfully downloading all the drivers including the LAN one, it was working perfectly. After I jumped into a CS:GO competitive game, very weirdly, my Ethernet connection stopped working. I re-installed the LAN driver and restarted my computer but nothing seemed to work. I even reset my hard drive and reinstalled windows, installed the LAN driver and it still does not work! I don't know what I did wrong or how to fix it but I am desperate and will try anything! The Ethernet cable is connected properly and there are two blinking LED's where it connects into my IO shield. What should I do?

[emosun]

did you check and make sure the actual internet is working

[Albert147]

Yup, I am using the internet on this laptop right now.

if you dont quote anyone we wont know you responded

does a different ethernet adapter work other than the stock one?

By Ethernet adapter do you mean cable?

I already tried 3 different cables.

The LEDs are blinking on the IO shield? Hmmm...

 

Open command prompt and type: ipconfig

Post your results

My thinking is that the driver and cable are working (hence the LED lights) but it's being fed a wrong IP/DNS from the modem/router.

I typed ipconfig into command prompt and this appeared.

Yeah that IPv4 address is wrong. If you run the same command on your laptop and look at the IPv4 address it should be different. Copy the Subnet Mask and Default Gateway numbers over exactly as they are shown. As far as the IPv4 address, use the same one as your laptop but change the last digit(s).

 

For example: if the IPv4 on your laptop is 192.168.1.10 change the last digit(s) "10" to something else like "175". The complete address would then be 192.168.1.175
You might have to experiment a bit with the last digit(s) as another device might be using the IP that you choose.

 

For now, I would disable IPv6.

 

I am attaching screenshot for reference. Follow the numbers.

 

1. Open "Network and Sharing Center"

2. Left click on your connection

3. In the status box that pops up, click "properties"

4. Uncheck the box for "Internet Protocol Version 6 (TCP/IPv6) temporarily

5. Click on the NAME (not the checkbox) of "Internet Protocol Version 4 (TCP/IPv4)"

6. Click "properties"

7. Click "Use the following IP address"

Here is where you copy the information over from the laptop, remembering to change the last digit(s) in the IP address box.

8. Click "use the following DNS server addresses"

Input on first line: 8.8.8.8

Input on second line: 8.8.4.4

9. Click OK on bottom and OK on any other boxes.

 

It might take a few minutes for the changes to take effect. You can restart the computer if you want.

See if you have internet.

I opened Network and Sharing Center but it says "You are currently not connected to any networks."

OK on that same screen, instead click "Change adapter settings" on the left side of the screen. You should then get a list of connections. One of those will be the correct one. You would then right click on it and select "properties".

 

To know which one it is, the command that you ran previously "ipconfig" should list a name above the info. Right above the info that I quoted below, there should be a name such as "Ethernet adapter Ethernet"

Here's an example of mine

 

[pwnograffik]

Alternate method:

 

Unplug modem.

Also unplug router if you have one.

Count to 37.

Replug the modem. Wait for it to be FULLY restarted.

Then replug the router. Wait for it to be FULLY restarted.

Restart your computer.

Check internet.

 

If still no internet, open command prompt and run two commands
1. ipconfig /release

Count to 15

2. ipconfig /renew

Check internet.

Great, I just did that and will wait a couple of minutes to see what happens!

A friend of mine had the same issue a week ago. Hopefully it works for you as well!

I tried the first thing you told me but it didn't work, so I just wanted to try the third option before I reset my modem but when I executed the command "ipconfig /release" it said that the operation failed as no adapter is in state permissible for this operation.

This is very strange. It was working before but then stopped out of the blue. You even went as far as reinstalling Windows and it's still not working.

 

I thought for sure that one of my two suggestions would work. You're sure that you entered the IP info and everything correctly for the right connection? If another device is using the IP that you chose it won't work.

 

After resetting modem/router and it still doesn't work another thing that you can try is first going back to the section where you manually entered the IP, subnet mask, dns, etc. and put it back on Auto. Then, open command prompt AS ADMIN and run these commands (all as admin) to reset:

1.   netsh winsock reset

It should ask you to restart the PC.

 

2.   netsh int ipv4 reset reset.log

It should ask you to restart again.

 

3.   netsh int ipv6 reset reset.log

Another restart

 

4.   ipconfig /flushdns

 

What motherboard are you using and where are you getting the LAN driver from?

 

Another thing that you can try is right clicking the network icon in the taskbar and click "troubleshoot" maybe you'll get lucky lol

I am using the MSI Z270 SLI motherboard and I got my LAN driver from the MSI website

I also tried troubleshooting the problem and it said that I needed to plug an Ethernet cable into my computer.

You computer recognizes the cable hence the LED lights but Windows doesn't see it? Wtf.

 

Other than trying the LAN driver from Intel I'm stumped.

 

You swapped cables, reinstalled the driver and Windows itself, ran the commands, tried static IP and windows troubleshooter without luck. Strange indeed.

 

My computer gets stuck with the 169.xxx.xxx.x IP like you had from time to time out of the blue but setting a static IP always fixes it for me.

 

Sorry I couldn't help. Best of luck!

I think I know what is happening but I don't know how to fix it,

 

I think the signal from the Ethernet is cutting in and out because in my motherboards' bios, there is a "board explorer" section that tells you what is connected and the Ethernet port is blinking shoeing tht it has an input but the it disappears. 

 

Do you know how to fix this?

 

Thanks for all your help by the way, thanks a lot.

I didn't think of that.

Maybe something funky happened with the BIOS. Try clearing CMOS.

 

Shutdown computer.

Clear CMOS button.

Switch off PSU.

Unplug power chord.

Remove motherboard battery if possible.

Hold power button down for 30sec.

Replug power chord.

Switch on PSU.

Boot computer.

 

A step past that would be to clear the RTC RAM. Your motherboard manual should have instructions on how to do that. If it doesn't just google it, the process should be the same.

is router own firewall enabled?

if yes add the device to allowed list by its mac address

see your devices help screens/website

you maybe being seen as a worm by your router and being denied dhcp access

also check devices own firewall allows dhcp service

finally is dhcpservice running in windows services(taskmanager services tab)
