"Network and Sharing Center" suddenly shows an "Unidentified network"
Troubleshooting the network gives me this result:
"Local Area Connection" doesn't have a valid IP configuration
Also, I just noticed when I go to home group to change settings, at the top it says "This Computer Belongs to a homegroup", but below it says "The homegroup is not available because you're not connected to the home network" When I try to turn on network discovery, it doesn't stay changed either..
Hey guys! Big fan of this site and the people on it for so many years. So I know where to go when I get stuck like I am now. Anyway, my computer suddenly stopped letting me connect to our network. My cable plugs into the motherboard so I don't have a network card or any type of wireless connection. I've tried every possible fix that I have thought of or heard of from searching google on another computer on the same network in this house.. I know this is a LOT of information, but I also know, the more I tell ya, the more it helps. Anyway I've highlighted some things red because I thought the info. may be of importance to ya guys. Things highlighted in blue are my computer parts or current settings. I probably messed up with the colors at some point making this list yesterday, but that's hardly the problem lol Alrighty, thanks in advance for any help!
WHAT I HAVE TRIED
-Turned off/reset the modem and router a million times and ways.
-Disabled and Re-enabled the Network adapter. In case it helps you, the adapter is: NVIDIA nForce 10/100/1000 Mbps Ethernet
-Tried to roll back driver. (Not sure if it changed from what it is now.) As of now it says: Driver Provider: NVIDIA, Driver Date: 8/12/2010 Driver Version: 18.104.22.168
-Uninstalled the NIC from device manager, no luck.
-Disabled the Apple Bonjour service to off in services
-I tried disabling the IPv6 in adapter settings as well (I've changed it back now though)
-I've also tried going into IPv4 and manually putting in the correct IP addresses etc. (well hopefully correct anyway). Although this was another failure, after putting the settings back I noticed if I went into DOS and typed ipconfig while IPv4 is NOT set up manually it says that the autoconfiguration IPv4 Address is 169.254.101.86, but shouldn't it be something like 192.168.1.1 (the ip that brings up the router) or something vevery similar? We have a Linksys Router by the way. Ok it's been several hours later and that autoconfigutation IPv4 Address changes obviously because now it shows 22.214.171.124
-Ran Malwarebytes Anti-Malware, Spybot - Search & Destroy 2 (which is no longer free to monitor your computer..bummer), CCleaner, TuneUp Utilities 2014 (for the first time in a long time, hope that didn't do anything bad), and Microsoft Security Essentials (I Highlighted it just in case it's something that may be bad. I'm guessing this came with an update or something because I don't remember using it any time recently.. maybe a long time ago though.
-Someone even mentioned changing something in the registry under:
They said to add the value "RFCOMM" to transports. Now, since my father's computer, which is working off of the same modem and router, had RFCOMM there and mine didn't I went ahead and added it.... to no avail. But I did leave it. It now has: Tcpip6 Tcpip Psched RFCOMM" under data in the Transports line. The only new part is the RFCOMM entry.
-Now for my adventures in DOS.. I DO run it as an admin, and tried the following commands I found from google advice. Of course I tried them while my cable was plugged in as well as when it was not. Here they are:
ipconfig /renew (This one gives two errors; "error while renewing interface Local Area Connection : unable to contact your DHCP server. Request Timed out." then right under that one, "error while releasing interface Loopback Pseudo-Interface 1 : system cannot find the file specified")
-Ok I also tried to do what this guy suggested to some people on another forum. Here is what he said:
"There are a number of command prompt commands that can clear the problem (disconnect the network cable first) and then go through these commands -- you will want to use an elevated command prompt so right click and run as admin to open it:"
netsh winsock reset
netsh int ip reset c:\resetlog.txt
netsh int reset all (This is me, Colin adding this. If I recall correctly this wasn't a valid command.)
"after a few moments reattach your Ethernet cable and try to get an IP address with:
ipconfig /renew in the command prompt window."
- Now this guy also suggested some other things first. I wasn't sure if he ment I had to do them BEFORE the above process or if they were just other trouble shooting ideas and didn't effect the DOS commands. Maybe one of you could tell me? Anyway, this is what he had typed at the top of the DOS idea: "fixing this problem may include deleting the Ethernet adapters and then re-installing the latest available driver turn off IPv6 in the adapter control panel settings -- just uncheck it;"
-I BELIEVE I got the newest chipset drivers, but I'm not sure. I went to a working computer (on the same network) and searched for my motherboard, wich is a "MSI K9N2 SLI Platinum". On MSI's site I located my MB and downloaded a file named "mcp_764_mb.zip". Once unzipped I noticed the main dir was named VISTA64 athough I run Windows 7 Home Premium (64-bit) SP1. I don't think that was a problem though because the site told me to download this for windows 7 and Vista. When I ran that it uninstalled a previous copy or something and then gave me 3 choices for installing: "NVIDIA SMU Driver" "NVIDIA Ethernet Driver" and "NIVIDIA Storage Driver. I unchecked everything besides the NVIDIA Ethernet Driver. Though later I did it again for some reason and also left "SMU Driver" checked as well. If you think I should run that again and leave all 3 boxes checked pleeeease let me know OR if I should be getting newer drivers somewhere else please let me know, thanks! I'm not even sure that was really updating chipset drivers because I don't know what they are, heh. In case this helps in anyway, here are the names of the files I found online and ran after the file in that VISTA64 directory:
Which under properties -> details says "File Version: 126.96.36.1990 Product Name: Windows 7/Vista 64-bit nForce..." and nothing else of importance. This is probably the same thing I ran in that VISTA64 folder earlier, but like I said, this time I checked two of three things.
and the other download I ran...
14-4-win7-win8-win8.1-64-dd-ccc-whql.exe (Which installed AMD Catalyst Software Suite AGAIN. So that was just for my display drivers I'm sure.
Ok so this is where I am stuck at Sorry this is a mess, it looked a lot better in wordpad before the copy and paste lol. But it took a long time to do all that stuff and then type it up. I've been trying to fix this all weekend... Have NO clue when or how this happened. I really hope someone can help. So if ya have any ideas or advice please bring em on! Oh yeah I see on other threads people are posting what they get in DOS after typing IPCONFIG /ALL. That stuff does seem important so if I should post my results or let ya know anything else, just ask. Thanks so much, you guys are awesome!
P.S. I will always reply ASAP
P.P.S. PLEASE LET ME KNOW IF THIS SHOULD BE UNDER Windows 7 NOT NETWORKING, THANKS
