Network identifying, no internet

Network is either identifying, or connected to an unidentified network. Neither of which lets me access the internet. I have a wired connection.

I've tried

Ipconfig /release
Ipconfig /renew
Ipconfig /flushdns
Netsh winsock reset
Netsh int ip reset resetlog.txt
Route delete 0.0.0.0
Sfc /scannow

Changing the power settings
Disabling selective suspend
Creating a static ip
Removing IPv6
System restore
Clean install windows 7
Clean install windows vista
Installing OS on different hard drive
Resetting to default settings on motherboard
Turning off router/modem for 10 seconds
Resetting router
Switching which port on the router my cable is connected to

Turning off firewall
Manually entering MAC address in IPv4>advanced>network
Formatting hard drive
Adding DhcpConnectEnableBcastFlaggToggle to registry files
Replacing DHCP and NetBT files in system 32
Replacing two files (forgot which) on registry

My SOLUTION - I could access my connection via my phone and new that the ISP was delivering a signal to my house and that the router was doing its job as well. Other computers worked, just not mine. The problem it appears was that some system files had become corrupt.

The simple solution was that I popped in my "Midern Computer INC. Recovery DVD-ROM for Windows 7 Professional Service Pack 1". Then on restart, F7 to tell the computer to boot from the MATSHITD.DVD/ROM. I chose the x64 Recovery option because I have 64 bit OS. The user interface identified that a RESTORE POINT was available that occurred only 10 days ago. I selected that then within moments I restarted and back to normal.

My suggestion is save yourself the...

Well, I guess to start, what kind of networking equipment are you wired into? Is it supplying DHCP? Is it SUPPOSED to be supplying DHCP? Are there any other computers/servers connected to that networking device that are supplying DHCP and giving you conflicting addresses (probably out of the question since you set a static IP)

Beyond that, what type of internet connection are you hoping to use here? Who's the provider? What equipment lies between your computer and the internet? Switch? Router? Wireless Router? Cable modem? DSL router?

I do have several other computers connected to my router. Mine is the only one not working properly.

Modem>router>my computer. ISP is shaw.

Pinging google does nothing.

"Transmit failed, general failure"

Ipconfig tells me DHCP is enabled

Are you getting a link light on the port when you plug in the network cable? If you do an ipconfig are you showing an IP address for the network interface? If so are you getting full network info assigned by DHCP? Like this:

Start by trying to ping 127.0.0.1 to make sure the NIC is even working. If that works, make sure DHCP is assigning you full IP info. So when you do the ipconfig it should look like my screenshot for the most part. You should have an entry for at least IPv4 Address, Subnet Mask, and Default Gateway. If you don't then DHCP isn't working right, or you have a physical issue either with the NIC or the network cable.

The light on my router is yellow on my specific port. Everyone else's is green. Changing which port I connect to doesn't make a difference, it'll still show yellow for me.

I can indeed ping 127.0.0.1 just fine. However, when I do ipconfig, it says very different things.

My connection specific DNS suffix is blank
My default gateway is blank
My IPv4 says "autoconfiguration IPv4 address : 169.254.43.154
My subnet mask says 255.255.0.0

I should mention that my households ip is 10.0.0.x, not 169.254.x.x

I tried 255.0.0.0, 255.255.0.0, and255.255.255.0. Nothing works

When I make a static ip, I can't ping to the default gateway. My connection specific DNS Suffix also remains blank

If you're using the IP address ranges of 10.0.0.x then your subnet mask should be 255.0.0.0, as that is a class A subnet mask and the 10.0.0.0 is a class A network address. The DNS server shouldn't matter much when it comes to pinging the router so that being blank shouldn't be stopping the ping from working.

If you get the IP from the DHCP server automatically does the ping test still not work?

Assuming you haven't already tried this; I believe you need to set your IP address as 10.0.0.200, your subnet mask as 255.0.0.0 and your default gateway will be whatever the other machines are using, assuming you only have 1 device that provides your internet connection.

If you can successfully ping your router then you are at least 1 step close to internet connectivity. If it does work then set the DNS address to 4.4.4.4

If I ping to the gateway with ip on auto I get;
"Transmit failed, error code 1231 (100% packet loss)"

If I ping to the gateway with my static ip I get;
"Pinging 10.0.0.1
Reply from 10.0.0.240: Destination host unreachable." However I have 0% packet loss

Pinging 8.8.8.8, and anything else really, also gives me the same response as pinging 10.0.0.1, unreachable host, but no packet loss

So you're not getting a DHCP address from your router which is why you're getting the 169.X.X.X address. So if you have the cable hooked up, you get a link light from the cable, but no DHCP lease and if you set a static IP and still can't get anywhere, your next step would be to try a different cable. I don't see that in the laundry list of things you've tried. Try using the cable from a known working device and see if that gets you where you need to be.

It looks to me like something is wrong at the router, but if the other computers are connecting with no problems then that contradicts that assumption. Having the ping fail with no packet loss indicates that the packets are reaching the router, but perhaps the router doesn't forward them correctly for some reason.

Pinging the loopback address indicates that the TCP/IP stack is functioning correctly, so perhaps there's some problem at the data-link layer.

i also suggest he check the clock on his pc, to make sure it closely matches the clock on the router. THIS can actually cause this exact issue as well.

Ok, thank you very much everyone. I actually did try different ethernet cables, but APPARENTLY all three that I tested were broken. I tried a different one again and it worked. But now I have a new problem.

My ping and upload speed are more or less the same as before, however my download speed is severely less. on Speedtest.net I'm getting 4.3 Mbps download speed and 2 Mbps upload speed. My former download speed was roughly 28 Mbps. Any Ideas what could be causing this?

I tried;
Ipconfig /release
Ipconfig /renew
Ipconfig /flushdns
Netsh winsock reset
Netsh int ip reset resetlog.txt

They didn't help.

Glad the cable worked. Do you get that same speed from Speedtest on any other computer on the network? If so, try bypassing the router and connecting one computer directly to the modem and running the speed test there. If it's still the same speed after bypassing your router, which I'm expecting it to be, you might want to consider calling Shaw and having them check the line coming into your house for quality/noise, or possibly replacing the modem.

Try going straight to the modem, bypass the router, have this computer be the only thing hooked up to the modem, see if you still get the slow speeds. Also check the status of your ethernet/network connection. What does it say for Speed there?

My suggestion is save yourself the frustration and do a Recovery System Restore. No data will be lost, just system files and programs that were installed during that time (which likely messed you up as it was for me.)
