**Hardware/Software:**

HP Elitebook 8440p

Windows 7 Ultimate SP1

AT&T U-Verse ISP, router is a NVG589.

---

**Problem Symptoms:**
This only exists on my laptop. Not on any other PC or laptop on my local network. It started appearing in early June.

Internet browsers stop responding after a random amount of time, internet appears totally dead. I don't get any 404 pages or loading timers, the internet is just flat out dead. If I click a tab, nothing happens, no window pane messages about trying to resolve any host, nothing. Trying to use a direct IP address for a website or the router internal IP has no effect. This is the same across IE, Firefox, etc.

Torrenting still works fine, as does Skype, but Teamviewer stops responding and iTunes home library stops responding. Windows local file networking is dead, too.

I can ping out to other sites fine, too, using either their IP address or their DNS name.

---

**Steps to replicate:**
Run internet normally for about 24-27 hours. Somewhere after that the internet stops working. Usually happens while I'm not paying attention (watching a movie fullscreen or asleep, but happened tonight while I was working actively).

---
**Files:**

Pastebins of some tracerts and Ipconfigs taken when working and not working follow:

Working IPconfig: http://pastebin.com/eQVTjLyG

Working Tracert: http://pastebin.com/jMjyax38

Non-working IPConfig: http://pastebin.com/hfSu7S6S

Non-working Tracert: http://pastebin.com/RniuvUVx

Services running while internet working: http://pastebin.com/4JFKJrPy

Wireshark logs from when the internet is working and when it is not working. Filter by TCP and you'll see the drastic difference. There's no activity on TCP when the issue occurs.: http://www.sendspace.com/filegroup/vpCpOfg%2Bfm6%2BXoo1...

---

**Attempts to fix:**

1. CMD prompt > netsh winsock reset

2. CMD prompt > Ipconfig /flushdns

3. CMD prompt > Ipconfig /release and /renew

3. I restarted a few services and the internet appeared to work once, but no thumbnails, pictures or content loaded. Internet soon returned to dead state. I checked the event viewer every time since then and didn't see any weird services running or stopping that coincide with the failure.

4. Stopped and then uninstalled Peerblock.

5. Ran Malwarebytes, no problems found.

6. Uninstalled Tune Up Utilities as it was governing services and shutting them down for resource purposes. Issue still persists.

7. Switched from wireless internet to wired to router. No change in behavior.

8. Reset AT&T modem.

9. Ran Windows problem solver (lol) which cannot tell there is an issue.

10. Disabled IPv6 on the wireless and wired network adapters.

11. Disabled and reenabled network adapters.

12. Ensured no proxies are running in Firefox internet settings.

13. Turned off power management on both wireless and LAN adapters

14. Cleaned Firefox and PC with CCleaner.

15. Ran Windows Repair from Tweaking.com, all steps ran.

16. Changed DNS on wireless and wired adapters to Google DNS (8.8.8.8 and 8.8.8.4)

17. Updated Windows to current updates.

18. Updated LAN driver to most current driver set.

19. Uninstalled and reinstalled Firefox, wiped out old session and started a new one.

20. Ensured no firewalls are running on my system.

So far the only solution I have is to either log out of Windows and log back in, or restart the machine entirely. The issue goes away for another 24-27 hours and then happens again, guaranteed.

Perhaps try finding an older version of firefox and see if the problems persists. Have you made any changes to your wireless card, router, modem etc?

I don't think the issue is Firefox itself, as it replicates behavior in IE, too. I will try running Chrome for a day and see if the drop happens.

I haven't changed anything regarding my internet connection.

Thanks for responding.

Hmm the only thing I can think of is that is someone could be trying to hack you or that you might have to change your mtu setting. Perhaps trying using an ethernet cable for the time being. It is also possible a recent windows update might have affected your computer. You would think a windows update would be beneficial, but that is sometimes not the case. Try to remember exactly when it started as windows updates are released every second Tuesday of the new month. If your problems began after June 10th, then it was most likely the update. Here's what I mean by the MTU

Thanks, my MTU settings currently match that of my router, and they are mirrored on other systems in my network and they do not have this issue, so I do not think this is the issue.

I am currently using a wired connection since the outages happen, and nothing changed. I also had stopped updating the Windows system in April 2014 for the reasons you stated, and the issues occurred in June 2014. I only updated *after* the incidents started occurring.

Try running this in command prompt: netsh int tcp show global

check it against this http://techibee.com/wp-content/uploads/2011/04/showauto... I'm pretty sure those settings in the pic should be the default settings

Your problem is quite perplexing. I was going to suggest radio interference but you say that it still occurs through ethernet. I'm surprised torrenting still works.

My stats mirror the ones in the link. Thanks.

I'm running a different Windows user profile now with a fresh install of Firefox, going to see if the issue occurs again today.

Does this happen when the laptop is plugged in or running on battery?

Plugged in. It sits in a central location and is not unplugged at any time. I can try running battery if the issue occurs under the new Windows profile, if that's what you're suggesting I try?

Issue occurred last night on new profile, too. Going to try using just Chrome and see if the issue happens again. Barring any new methods of solution, I will be reinstalling Windows 7 or running a Live CD to see if the issue persists.

You could try running Linux to see if the problem occurs in there.

Yeah, I'm prepping a Live CD in case it happens while using Chrome today. I'll update, whatever happens.

Have you tried turning off all power management - BIOS and Windows

Turned it off in Windows. Haven't looked through the BIOS yet. I'll try it if it happens again.

Happened again at 27 hours while just using Chrome. Gonna attempt the Ubuntu Live CD now.

Well, I reinstalled Windows 7 on Monday and installed basic network drivers. We've passed the 48 hour mark and the issue has not reappeared. I think Windows was just fundamentally screwed, perhaps by Tune Up Utilities, as the issue started not long after running it for the first time on this machine. Going to keep watching and see if it dies again.

Thanks all for the assists, I appreciate it greatly.
