OS: Windows 8



Background:


I was a happy user of Windows 7. I did the upgrade to Windows 8 and the internet connection seemed to work fine for two days. Then a couple days ago, Windows did the usual software updates after which I shut down my computer. Next time I opened it up (yesterday), it would not connect to the internet no matter what. I am computer savvy so tried all the usual suspects but to no avail. I used the troubleshooting tool which came up with "WiFi does not have a valid IP configuration." Please don't tell me to turn off/on the router. Tried that and it doesn't work. The microsoft forums have been mostly useless as well. I've also tried the following from the command prompt (run as admin):

netsh winsock reset catalog (reset winsock entries)

netsh int ip reset reset.log hit (reset TCP/IP stack)"

Then rebooted and still no luck.

I'm inclined to think this may be a compatibility issue, perhaps the drivers. I have a Toshiba Satellite P750. The bottom line is that my computer is now a useless brick and it's costing me money by not being able to get online (for my work).

Below is my ipconfig /all information. I am hopeful that someone may have useful information to solve this problem once and for all. My only other option is to revert back to Windows 7 (which actually does work) and avoid Windows 8 until it becomes a relatively bug free and viable OS. Thanks for your help.

Since we're talking about wifi (wireless networking) I suspect you have a laptop. What I'm thinking is that the driver windows 8 has given you is not happy with your wireless card. More than 1 users suffer from this. Try updating the driver. Though not by the standard way of updating, since its just gonna say it already had the most updated one.
If you have another laptop/computer avaliable, Search for the driver on that one. Remove the previous driver and install a new one. I hope this will work for you.
