Unidentifed Network, Computer says there is a modem problem when there isn't.

Nick Hagan · Aug 16, 2013

I have a desktop computer that is wired through a wireless router that I use for a laptop. I woke up the other day, internet was working fine beforehand, and there is no internet access. I tried all the basics. Power cycling the modem and router. I even followed some guide on here, checking the network adapter, deleting it and restarting.

The wireless and wired connection both work with the laptop. I've been trying to resolve the issue since yesterday.

call your ISP?

Nick Hagan · Aug 16, 2013

ISP says everything is 100% on the modem. Besides, why does the wired connection work with my laptop but not the desktop? I don't see how that could be my ISP's fault.

Which version of Windows 7? It sounds like you the unidentified network problem that can be difficult.

It is easier to fix sometimes if you use Pro, Ultimate or Enterprise as there is an additional tool that Home Premium lacks.

HERE are some threads on it, and you will see how common it is.

I have windows 7 ultimate, after poking around some more, running full virus and malware scans, i decided to reformat my machine. Just finished doing a fresh install of windows and im still getting the same problem. I think I may be sick.

Yeah, that doesn't usually fix it. I would try using the Local Security Policy tool.

Click on Start --> Control Panel --> Administrative Tools --> Local Security Policy
Expand the Security Settings and click on the left side Network List Manager Policies
On the right side pane, double click unidentified networks and then change the type from not configured to private type
Then save, close out and restart.

I did this. Now I have an unidentifed work network instead of a public one.

Why no IPv4?

This is from my desktop that doesnt have a connection, i had to copy this to a text file, put it on a thumb drive, then upload it from my laptop, which im using right now.

default gateway should be listed. Its your router. Ip address is different from what I expected. normally IP addresses are in the 192 range, no DNS server listed which should also be your router. Can you log into your router? Or maybe reset to defaults?

Nick Hagan · Aug 16, 2013

egilbe :

I can't connect to anything from my desktop, i cant even surf into the router from it. I CAN access the router from this laptop, i reset it to default settings but that didnt resolve the problem Im having with the desktop.

egilbe · Aug 16, 2013

device manager shows no problems with your NIC?

Nick Hagan · Aug 16, 2013

egilbe :

None. says its working properly.

Nick Hagan · Aug 16, 2013

I may try using a wireless adapter.

egilbe · Aug 16, 2013

Nick Hagan :

At the very least, it will be another troubleshooting step to cross off.

triley-1366832 · Aug 16, 2013

The 169.254.xxx.xxx IPV4 address range is the Apipa range. Apipa is automatic private ip addressing, it is a range that Windows uses if it doesn't get an address through DHCP.

egilbe · Aug 16, 2013

triley-1366832 :

I'd forgotten about apipa

Nick Hagan · Aug 17, 2013

So, i borrowed a wireless adapter from a friend and I now have a connection to the internet. I'm probably going to order a new one tomorrow. Thanks to ebilbe and RealBeast for responding to this thread and trying to help me sort this mess out. Cheers.
