Earlier today, I got some assistance getting my computer to boot again. It worked like a charm, thankfully, but I immediately ran into a new problem that I've been trying to fix for the last few hours: I can't connect to the internet at all. It says that I'm connected to my wireless network with 'limited access', but it doesn't actually let me use anything. 

 

I'm not at all sure what to do here. My windows network diagnostics have given me at least three different issues: DNS server isn't responding, that the wireless network I'm trying to connect to doesn't have a valid IP configuration, and that it couldn't detect the network's proxy settings. It's just my desktop PC with this issue, because I'm on a laptop connected to the same network searching for solutions.

Hello,

See if this helps save it to a flash drive on the laptop, then insert it into the desktop and run it.

Copy and paste the text in the code box below into Notepad.

@Echo off
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh int ip reset all
netsh winsock reset catalog
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.
Then
right-click flush.bat and select "Run as Administrator" your computer will reboot.

It rebooted, but I'm afraid that it didn't work. It looked like there was some kind of error in the command prompt that came up upon running the file. 

[zep516]

Paste the following into the Command Prompt window, exactly as shown, including double quotes:



cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxy" >> postme.txt & notepad postme.txt & del postme.txt"


and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close. Post results in a reply here.

Hello,

See if you can boot win 10 to safemode with networking

see here how to do that-->https://www.digitalc...mode-windows-10

See if it connects there

[tubalcain]

I should probably mention that I'm using Windows 7. 

 

After booting the computer in safe mode with networking, there wasn't any change in connectivity. 

[zep516]

Is this a wireless connection ?

[tubalcain]

Yes, it is. 

[zep516]

ok,

you could try a Ethernet cable to see if it connects like that.

Windows has already done this probably, but lets uninstall the wireless adapter from device manager and reboot.

To do that.

Click start in the search box type dev, in the generated list above click device manager. In the device manager find network adapter, click the arrow to the left of network adapter to expand the list. Right click on your adapter 802.11bgn 1T1R Wireless Adapter. Choose uninstall and then reboot. This will reinstall it. See if that does any good.

[tubalcain]

Reinstalling the adapter doesn't look like it helped, unfortunately.

Have to sign off. What I would do next is to download adwcleaner from the Laptop to a flash drive, then insert it into the desktop and run it. Here's instructions for adwcleaner run the scan and hit the clean button.


Download AdwCleaner from here. Save the file to the desktop.
NOTE: If you are using IE 8 or above you may get a warning that stops the program from downloading. Just click on the warning and allow the download to complete.
Close all open windows and browsers.

• XP users: Double click the AdwCleaner icon to start the program.
• Vista/7/8 users: Right click the AdwCleaner icon on the desktop, click Run as administrator and accept the UAC prompt to run AdwCleaner.
  You will see the following console:

• Click the Scan button and wait for the scan to finish.
• After the Scan has finished the window may or may not show what it found and above, in the progress bar, you will see: Pending. Please uncheck elements you don't want to remove.
• Click the Clean button.
• Everything checked will be moved to Quarantine.
• When the program has finished cleaning a report appears.Once done it will ask to reboot, allow this

• On reboot a log will be produced please copy / paste that in your next reply. This report is also saved to C:\AdwCleaner\AdwCleaner[C0].txt

I'll check back in the am....

[tubalcain]

Thank you for the assistance so far! 

 

It seemed to pick up and delete something, but it really didn't do anything for the connection.

Are there any errors in device manager ?

Is it possible to connect with an Ethernet cable ?

We also might consider going to the manufactures site of the network card and re download the driver. Who makes the network card that's installed ?

[tubalcain]

Thank you so much for the help!! I was able to figure out what the problem was and fix it on my own earlier.

 

I went to the command prompt and manually input the commands from that .bat file you told me to run - "netsh winsock reset" and things like that - to check for errors. Namely, the winsock reset command couldn't find the appropriate file. 

 

So, I went to check the FRST fixlog I had from yesterday and, as it turns out, something called winsock had been moved elsewhere. I replaced the missing file and executed the .bat file again, and now everything is working properly!
