Can't connect to internet - "Unidentified network"
I know this problem has been discussed on this forum before, but none of the solutions worked for me.
I just reformatted my hard drive about 3 days ago after it refused to boot up. I reinstalled Windows 7 and everything was working just fine for about 2 hours, then for no apparent reason my internet connection dropped while I was browsing the internet. That was 3 days ago. My connection is still down.
My wireless card is picking up the signal from my router, but when I try to connect to the network it tells me I am connected to an "Unidentified network" and have no internet access. I tried uninstalling and reinstalling the network drivers, system restore, as well as "netsh winsock reset" "netsh int ip reset reset.log" and "netsh winsock reset catalog".
The "ipconfig /renew" command gives me the following message: "An error occurred while renewing interface Wireless Network Connection : unable to contact your DHCP server. Request has timed out."
Windows Network Diagnostics says I have two problems.
1) "Problem with wireless adapter or access point."
2) "Wireless Network Connection doesn't have a valid IP configuration."
I have never encountered this problem before, and I have been using this same PC and wireless card for 6 months. I would really appreciate some help with this because recently my PC has just been having one problem after the next.
Here is my "ipconfig /all" information as well as the messages I get when using the /renew command. I noticed I don't have a default gateway listed, which I'm hoping might be a clue to my problem:
