I've spent hours trying to do my own troubleshooting and research on this and honestly I'm fed up and exhausted.

My Windows 7 PC won't connect to wireless internet, when I troubleshoot it it tells me that I need to plug in my Ethernet cable, which I have done. Even with the Ethernet cable, it still won't access certain websites (regardless of browser used, Chrome or Firefox) saying it can't find the DNS address.

Here's what my ip config looks like in command prompt (with Ethernet cable plugged in):
C:\Windows\system32>ipconfig /all

Obviously because the media is disconnected, ipconfig /release and /renew do absolutely nothing. If anyone has any help or advice, it would be very greatly appreciated. Thanks in advance.

Assuming it's a factory brand one, what's the brand name and model name and complete model number of your desktop?

Is it running Windows 7 SP1 32-bit or 64-bit?

1) the DNS thing is most likely due to that you do not have IPv4 enabled on your connection. You are only running IPv6 which most websites have not fully adopted yet. You will need to enable this in the Network Properties of the Ethernet connection.

upload_2016-12-13_13-53-0.png

2) You do not have any wireless connections showing in the IPCONFIG at all which indicates that the wireless adapter is not installed properly or a bad driver, or in most cases with laptops, you have disabled your wireless connection. For laptops, there is either switch on one of the sides, or the F12 key. That's something we can confirm once you have provided the information Flavallee requested.

Alright, sorry for the belated response, it is the Christmas season and this is the first time I've had since I originally posted to sit and work on my computer.

I did what etaf suggested, all the resets were successful, and I restarted my computer as instructed to via the cmd. Lo and behold, problem is still not solved. :/ (Note that that frustration is directed at my computer, not you guys, I sincerely appreciate your help.)

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Windows\system32>netsh winsock reset catalog

Sucessfully reset the Winsock Catalog.
You must restart the computer in order to complete the reset.


C:\Windows\system32>netsh int ipv4 reset reset.log
Reseting Interface, OK!
Restart the computer to complete this action.


C:\Windows\system32>netsh int ipv6 reset reset.log
There's no user specified settings to be reset.


C:\Windows\system32>

My desktop is a Hewlett-Packard, the model name is h8-1230, and by complete model number I'm assuming you mean the product number, which is: H2L73AA#ABA. It is running Windows 7 SP 1 64-bit.

My local area connection properties on the Ethernet connection show that I have both IPv4 and IPv6 checked and enabled.

Lets try the following

Uninstall and allow windows to re-install the adapter and Driver

Goto the Device Manager ( http://www.computerhope.com/issues/ch000833.htm ) > Network Adapters > click on the [+] to show all the adapters

right click on the Ethernet adapter and from the menu

remove/uninstall the adapter

Now restart the pc and allow windows to detect new hardware and re install the adapter and the driver

So before I could try what etaf suggested next, I turned on my computer and now the wireless internet is magically working again. This isn't the first time this has happened in the past month or so--it'll work for a few days, and then stop working again. During the few days it's working, I am presented with a new problem--my desktop starts freezing. And that is what it did again today when I turned it on. I hadn't even opened any programs, it had just been sitting and running for a few minutes, and I clicked on the start button, and the whole taskbar froze. Then if I click anywhere else (try to open any other programs, or do something in Goole Chrome for example) it'll work at first, but then if I click away and click back, that program will freeze, and each and every program that the computer is running will follow suit until the whole thing is locked up. CTRL + ALT +DEL does absolutely nothing, because the computer is so frozen it can't even bring that up.

Yet when it's having this issue with the wireless, and I have to use an Ethernet cable with it, it has absolutely zero problems with freezing. At first I thought this was a coincidence but this has happened three times now over November and December and I'm starting to think it might be more than just my wireless internet that is the problem here. Does anyone have an idea what could be going on here? Because I'm at a complete loss.

I've done registry cleanups and system restores, I've turned off all extra windows startup processes and uninstalled any and all old programs that I don't use on a daily basis. I haven't installed anything new recently that could've set this off, or downloaded anything. Multiple virus/malware scans from Microsoft Security Essentials, Avast, and Malware Bytes have turned up nothing.

Run a chkdsk and sfc /scannow

-------------------------------------------------------------
Lets Run a check disk test and see if that finds any errors

How to run chkdsk [/B]

For windows 8/8.1 or 10
http://www.thewindowsclub.com/disk-error-checking-windows-8

For Windows Vista or Windows 7
http://www.vistax64.com/tutorials/67612-check-disk-chkdsk.html

If the program reports any errors - post back the report
http://www.sevenforums.com/tutorials/96938-check-disk-chkdsk-read-event-viewer-log.html
-------------------------------------------------------------
-------------------------------------------------------------


Lets do a system file check, and check the Windows files.

System File Checker - SFC /scannow

http://www.thewindowsclub.com/how-to-run-system-file-checker-analyze-its-logs-in-windows-7-vista
https://support.microsoft.com/en-gb/kb/929833

For Windows 8 or Windows 10
To open a Cmd Prompt or an Administrator Cmd prompt from the Desktop.
Use Win + X and choose Command Prompt (Admin) from the list.​

For windows version, XP, Vista, W7
open the command prompt as administrator
Start> All Programs> Accessories and then right click on Command Prompt, select "Run as Administrator" to open a command prompt.
(A new dialogue box - black with white font, will appear on screen ):​

In the command prompt window that opens, type the following command:

SFC /scannow
This will take some time to scan and you will get 1 of 4 possible results​

  1. Windows Resource Protection did not find any integrity violations. - This means that you do not have any missing or corrupted system files.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  4. Windows Resource Protection could not perform the requested operation.

If you do receive the message in 3 or 4
Lets see a log file

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >%userprofile%\Desktop\sfcdetails.txt

  • This will place a file on your desktop called sfcdetails.txt which contains the results of the scan.
  • Copy and Paste the contents of the file into your next post.

I ran chkdsc and nothing was turned up, even after doublechecking the event viewer (it could not find any logs tagged with chkdsc). Running SFC /scannow has given me the second result, "Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log"

Should I copy and paste that log here?

Alright, I stand corrected: I had never run chkdsk before, so I wasn't sure what to expect. The first time I tried it, it didn't run properly (or at all, rather.) So I went through the motions a second time just to be sure, and it ran properly last night, taking a good few hours.

As for the SFC /scannow log I found under the example windows gave me (C:\Windows\Logs\CBS\CBS.log) Well... It's massive. Too massive I think for me to paste here, because it's a 2,910 KB notepad document.

I just got on my computer for the day as chkdsk ran way past my usual bedtime, so I'll keep an eye on the computer for the next few days and see what it does now and report back when I can.

So it seems the problem of my computer freezing is still persisting. I also noticed today when I booted the computer up it wouldn't go past the black screen with the small white line blinking in the upper left corner. I had to hard reboot it and press the Esc key to pull up the boot menu and make sure it was booting from Raid Ready (as that seems to be the only option on the list that works). This problem has also occurred before, but it had gone away a while ago, that is until today.

WELL I'm back, the freezing problem has still been persisting, and now it refuses to connect to the internet again.

I tried the option etaf suggested in his previous post to go to the device manager and uninstall the ethernet adapter. There are three options listed under my Network Adapters:
Bluetooth Device (Personal Area Network)
Bluetooth Device (RFCOMM Protocol TDI)
Realtek PCIe GBE Family Controller

I tried uninstalling the Realtek PCIe GBE Family Controller (assuming that was the correct one) and restarted my computer. It reinstalled the adapter, and my problem still continues. No wireless internet.

What else can I try now?
