No network connectivity

Xelot · 04 Feb 2016

Hi, I suffer total loss of network connectivity after a computer crash.

I am on win 10 x64

Here is my ipconfig /all, hopefully someone can spot what is wrong:

C:\WINDOWS\system32>ipconfig /all

Windows troubleshooter reports that "One or more network protocols are missing on this computer".

Some other info: i am unable to connect to 192.168.0.1, which is my router's home page. I can load this page on my laptop if i connect my laptop with ethernet, so the router is fine.

169,254... is a local IP address. Also, no Gateway, your PC is not picking up a DHCP address from your router. Check the connections to your router and restart your router.

Xelot · 04 Feb 2016

Hi, I've been trying to sort this for around 4 hours now without success, but in that time i have restarted computer, reset router, and reset cables several times. I have even verified the lan ports on the router by using them with other systems.

My ipconfig /all has changed slightly, here it is now:

C:\WINDOWS\system32>ipconfig /all

I have even performed a system restore to 2 weeks ago and the issue remains.

Another issue is that when doing ipconfig release and renew, I get this error when trying to renew (after hanging for a few mins):

Windows IP Configuration

An error occurred while renewing interface Ethernet : unable to contact your DHCP server. Request has timed out.

It's after trying the release + renew that my ipconfig /all gives the result in my first post.

Other commands I have tried are netsh winsock reset and netsh int ip reset.

I have also uninstalled my NIC in device manager and rebooted, using the default windows 10 driver for my NIC.

I have also uninstalled the NIC then tried using the latest driver for it from motherboard website.

I would set your adapter to a static IP
Open Network connections
Press the Windows Key + r
Copy and paste this

Code:

ncpa.cpl

Right click on your adapter and select properties
Double click on Internet Protocol version 4 (TCP/IPv4)
Change your settings to
IP: 192.168.0.99
Subnet: 255.255.255.0
Default Gateway: 192.168.0.1

Use the following DNS server
8.8.8.8
8.8.4.4

No network connectivity-network-adapter-1-1-text.png

Try using Googles DNS server
I live in Ontario Canada and I find that Googles DNS server works great here. You could also use your ISP's DNS server, To find that you will have to do a Google search for it.

Code:

8.8.8.8
8.8.4.4

Make sure your DHCP Client service is running...
Startup the Services window (Windows Key + r "services.msc"), then look for a line labeled "DHCP Client". Make sure that the Status column shows "Started" and the Startup Type column is "Automatic".

While your there check these ones too

Code:

Computer Browser
DHCP Client
DNS Client
Network Connections
Network Location Awareness
Remote Procedure Call (RPC)
Server
TCP/IP Netbios helper
Workstation

Some general command line tips for trying to fix network problems
Go to command Prompt (Admin)

Reset WINSOCK entries to installation defaults:

Code:

 netsh winsock reset catalog

and after that
Reset IPv4 TCP/IP stack to installation defaults.

Code:

netsh int ipv4 reset

And last but hopefully last
Reset IPv6 TCP/IP stack to installation defaults

Code:

netsh int ipv6 reset

Note

After a reboot and you still have no connection check this ---if you have a static IP check your internet protocol (TCP/IPv4). They may have changed to 0.0.0.0

Reboot the machine.

thanks for the suggestions,

have run through them all with no success.
All the listed services had status 'Running', and all Automatic (with some being automatic: triggered start and things like that)

I also put in the static ip settings again after reboot, with no success. They are taking effect, they show in the "details" window of the connection status window, I just still have no data throughput.

The netsh commands are ones I already did try, but I tried again. Some of the 'resetting' statements fail.
However, I have now tried running those commands on my laptop (which has no issues) and they also have some failures there, so I don't think that is indicative of the issue.

Digital Life · 04 Feb 2016

I would check your network cable and if possible switch the cable from a working computer to the non working one, I guess you already tried rebooting the router.

Try to ping the router

Code:

ping 192.168.0.1

Xelot · 04 Feb 2016

Yeah i have tried spare cables and pinging the router results in time outs.

I may be on to something, I noticed in my uninstall programs list i have "Intel(R) Technology Access" which was apparently installed today, I don't know what it is, but googling it makes me think it is probably causing this issue.

When I try to uninstall it, the uninstall fails with "The set up program ended prematurely because of the following error:
Fatal error during installation.

click here to open log file location."

I'm not sure if it would have been part of the driver installations I have run several times while troubleshooting, but either way the fact that I can't uninstall it is troubling. I actually have 3 instances of Intel(R) Technology Access in my programs list, all different versions.

Xelot · 04 Feb 2016

I just thought, I can have windows reinstalled and up to my desired state in around 2 hours, but I have spent over 7 hours trying to fix this, so it's time to cut the losses and reinstall.

Thanks for suggestions.

Did a fresh install of windows 10 and the issue remains, how is this even possible ?

"One or more network protocols are missing on this computer" - on a brand new installation? i don't think so...

I'm battling the same issue. I think that the missing protocols issues has to do with missing winsock entries in the registry. I got past that by following the instructions here:
Network Protocols Missing

Essentially, the fix to the protocols error is to copy the winsock entries from a working machine.

I also note that your IP subnet mask is 255.255.0.0. I have the same issue. It's my understanding that it should be 255.255.255.0 for a typical home setup and that is must match the subnet mask used by your router. I don't know how to change the default subnet mask on my machine. Manually setting an IP address did not work. My wife's laptop and my router both use 255.255.255.0 as the subnet mask.

Take all this with a grain of salt. I know very little about the ins and outs of networking, apart from what I've picked up here while trying to get my computer back on line.

I hope that helps or gets a knowledgeable person on the right track.

on edit: I see from your third post that your subnet mask changed to 255.255.255.0, which should be OK.
