I have a 2 week old Windows 8 Gateway PC that is wired to the internet through the Ethernet card and I have a wireless router connected too for my laptop and tablet.  It's been working perfect for 2 weeks and so has my wireless on my laptop and tablet. Today I moved some things in the room and had to unplug everything. I put it all back the same and now only my wireless works on my laptop and tablet. The PC is showing limited access and when I run the diagnostics it says "Ethernet doesn't have a valid IP configuration" error message.

I have unplugged the wireless and connected the cable modem directly to the PC and it works fine. As soon as I route it through the wireless router it fails. Please I don't understand how I unplugged everything for only a few hours and then reconnected it exactly the same and now it doesn't work. I tried all 4 ports on the router, still nothing, I reset the TCI/IP, renewed the DNS, flushed the DNS, did a handstand, shook hands with a bear, ( so obviously I have done all the basics and more) I changed cords between router and cable, even so how come my wireless still works fine? There is nothing wrong with the antivirus, I don't have any viruses or malware, the computer hardly gets used, but today it won't suddenly work. Please, any suggestions. Thank you.

:welcome: Petal1635 to Bleeping Computer!

 

Have you tried reinstalling the wireless adapter driver?

With a working internet connection and usb flash drive, download and transfer the program and logs on your next reply.

 

Download MiniToolBox and open/run the program.
When open, checkmark or select all options then click Go.
A notepad will open then copy-paste the report on your next reply.

 

Make sure the wireless is on before running Minitoolbox.

Thank you I have resolved the issue. I turned everything off, powered on my modem and router first and let them obtain new IP addresses and then turned on the main PC and it created a new network and worked instantly. I remember someone mentioning it made a difference how you cycled on your hardware and I happened to see it in another forum to remind me. Anyway it was a simple fix that caused a big headache, now if it was all that easy... :thumbup2:

Well you said you were able to obtain new IP Addresses, does it mean that you have more than one? I have a router and  desktop, tablets and laptop but I only got one IP Address. I am confused on this one please enlightened me. Thanks.
