Unidentified network - no internet access

#1
My pc is connected a router with an ethernet cable. The router was reset and now the pc cannot connect to the internet. The message I get is

unidentified network - access type: No Internet access
work network - connections: local area connections

we have rebooted, turned computer off then on, reset back to a previous time, changed the ethernet cable

Now what???

If you have reset the router then it should be automatically trying to assign IP address and DNS address but this depends on whether you have set your pc to have them assigned automatically. Go to Control Panel, Network and sharing, change adapter settings, right click on local area connection and select properties. Left click on Internet protocol version 4 and click on properties. Select the two options to obtain an IP address automatically, and also to get a DNS server address automatically

Hello,
followed your steps and it was already set to obtain addresses automatically.

After troubleshooting the problems found say..

"Local area Connection" doesn't have a valid IP configuration Not Fixed with a red x

What does this mean?

We need to get some more information. Go to Programs, accessories, right click on command prompt and run as administrator. Enter the following command:

ipconfig/all

and show us the output please.

If you have a drive other than C drive you can send the output to a file on there:

ipconfig /all > X:\ip.txt

where X is the drive letter you want to send it to. The output will be written to a file called ip.txt

Yes - that's what we needed. The address which starts 169. shows that your router is not assigning an IP address to your pc. The list also shows that DHCP is enabled on your pc so it is requesting one. You need now to look at your router and see if DHCP is enabled on there. It is usually the default so I would expect that is is after restting it but you need to look and check. All routers are different in their interface so you will need to look at the manual for your router to check if DHCP is anebled on there. If you have problems with it let us know the make and model of your router and we'll try an help you with that.

Try disabling any firewall. In particular - have you got or had Norton installed?

Disabled the firewall, then restarted pc = no change
