Network Connection Dies
Mar 5, 2009
About once every two days, my connection to the Internet dies, and won't come back without a System Restore.
I've got two XP machines along with my Windows 7 machine on a D-Link router. About once every two days, my Windows 7 machine just decides that it won't connect to anything on the Internet including chat clients. Without refreshing the router, I can still connect with my other two machines, so I know it's not the router. I even do a restart on my Windows 7 machine and it still won't connect. The only thing that works is a System Restore.
Any ideas of what I can repair without having to do a System Restore?

Recently when I try and connect to the internet my wireless connection network says it is an unidentified network with no internet access. This never happened before.

I had a Win 7 Ultimate 64bit on this very machine (the one in my preferences) for almost 3 years until the moment when I said to myself: OK, time to refresh. And that only because my port 80 would die sometimes....sometimes thrice an hour for 10-15 min, sometimes twice a day. But it would happen every day. I re-installed with the hope it was just a bad Win installation but it happened again after just an hour in. What I tried? Well, I certainly tried a new router. I knew it wouldn't since I also run Linux and OS X in home network and none is affected by this. I scanned old and new Win 7 with every possible malware finder, antivirus..etc. Even bought one (I have an "allergy" when it comes to A/Vs and such in general).. I went drastic today, I disconnected all devices (hdds, usbs, dvdroms, pcie) just to prove my point.. left a single 60 GB SSD with brand new win 7 with default drivers .. Took several hours but I still lost port 80 (it seems to be just port 80 since only browsers and windows LIVE are affected on my system)...Skype, FTP, rsync.. they'll all work just fine while nothing else web-wise does.

(the bytes sent and received). It seems skype calls and watching in browser videos shoot them up into the billions after a few hours +. Upon googling around i am quite alarmed. Why did my network randomly change to "network 3"? A few weeks ago it just said 'network'?

yesterday, my PC hangs and after I reset, the NIC is not connected, as if it does not have a network connection, which is usually connected as my connection (physically) is always connected.after some test, I've discovered that if my PC is connected to mywireless router through the wired connection, it's not working(used to work), not even in switches anymore, The only setup I've got a connection is when I connect my PC directly to my ADSL router, or if it is connected to another computer (PC-PC connection).my concern is that, I need to be connected to my home network.
these are the scenarios I've tested :
*Directly connect the PC to ADSL router (work)
*Directly connect the PC to another PC (work)
*Connect the PC to a wireless router (don't work)
*Connect the PC to a switch (don't work)
*Changed cables then connect the PC to wireless network or switch (don't work)

My laptop dies if I am on the battery and the battery percent gets between 25-40% then it will just completely shut off. It never used to do this for the first 8 months i've owned it. Now it does it every time I'm on the battery. Also, right before this started happening I was getting GREAT battery life out of my battery, so I don't personally think the battery has gone bad, however you may feel different!

I have the following setup:
Windows 7 Pro x64
Intel DP55WG mobo w/ onboard RealTek HD (889)
Driver Version: 6.0.1.6449 from RealTek
MSI Nvidia GTX 460
Just using normal analog speakers or headphones audio works as expected. I can play WoW, Rift, a number of other games, iTunes, play a DVD, whatever - it all works fine and as expected. I can do this for hours and hours with no issues.
When I try to run any TWO or more programs that use audio at the same time (like vent and a game, or a game and iTunes for example); after a random amount of time the audio to the speakers will just cut out - like it's muted. This happens with headphones or normal stereo speakers plugged into the rear analog jack. I have not tested with any other speaker setups as I don't have any right now.
Here is some of the troubleshooting I've done:
- There are no error messages in any system logs.
- The mixer acts like nothing is wrong you can see audio levels playing, adjust sound level, etc but nothing comes out of the speakers.
- If I put the machine into sleep mode or reboot it the sound starts working again.
- While the audio is "cut out" the mic still works (people in skype or vent can still hear me but I can not hear them - I can also "monitor" the mic and it outputs the mic sound to my speakers).
- I've uninstalled, reinstalled drivers. I've tried older drivers and the newest drivers and all the drivers between.
- Tested with the HDMI audio output devices both Disabled and Enabled, no change
- Tested with the Digital output enabled/disabled, no change.
- In the driver tried testing with the "Allow applications to take exclusive control of this device" checked and unchecked, no change.
- Restarting the Windows Audio Services has no effect or changes the state. Only sleep mode or hard reboot makes it start working again.
- Tried unplugging and replugging in the speakers and/or headphones, swapping them out, etc. no change to the state of the output of audio.

I had issues with my computer displaying symptoms of a faulty PSU. I was shutting down instantly whenever I ran intensive games for too long.Soon after those issues went away, I started getting random freezes, crashes, and BSODs. I finally tracked this down to a bad version of firmware on my SSD, and upgraded it by upgrading the firmware version, doing a 'secure erase', or something along those lines, as OCZ calls it, then installing a brand new copy of Windows 7.Everything went fine for a little bit. It's been 1-2 weeks or so since I upgraded the firmware.Over the past few days, I have noticed random ... near-shutdowns. Basically, my monitor was off, and my computer was unresponsive - but the lights and fans and what-not were on.I thought something tried to shut down my computer or something, and didn't think much of it. Maybe a weird Windows Update, iunno.Note: The hard reboot function on my computer (a tiny button near my power button) that usually works without issue does not work when this happens. My computer still has power, but it seems like it just... died. No monitor connection. No response whatsoever.A simple holding down of the power button and then pressing it again when it turns off seems to work, although the power up from that point takes a bit longer than normal.
Today, I have seen this first-hand 2 times. Just today. I was doing something, the sound started skipping - at which point my monitor disconnected, although for a few seconds after, I could still hear the guy I was talking to on Skype, and he could hear me. A few seconds and the sound dies down, and my comp is completely gone. Power still running as I already mentioned.Do note that this has happened both when I was running an intensive game and when I wasn't running much of anything - certainly nothing intensive.
I've already replaced my PSU, upgraded my SSD firmware, and reformatted my main HD (not data drive) and reinstalled Windows. I ran memtest a little while ago and it ran w/o issues, 2 passes, 0 fails.FYI, I've checked temperatures. My computer is not at all overheating.S This has been going on for months. I use this computer for gaming, programming, and work.
Edit: My computer just "died" again - for the third or fourth time today. I'd like to note that for 2-3 seconds right after this happens (i.e. right when my monitor goes dark and my computer stops being responsive), my fans get very loud - much louder then they normally would. After this, my fans go back to the normal volume level that they are usually at.The only thing notable in my Windows Event Viewer is that there was a generic, unexpected loss of power. It leads me to information about a "Kernel Power Event 41", with the following link:[URL]

I am having a problem with my computer randomly shutting down whenever I use any of my movie making programs. It will not have a problem rendering anything small, but when it comes to a movie or a full eps of something my computer dies about half way through. It never used to do this before and has reciently just started doing this. I switched to Win 7 like 2 months ago. I would like to see if anyone can help me figure out the problem. I dont have the blue screen. It just shuts down completely without warning.

I've been having problems with my computer. The monitor screen will randomly go black (a small grey window appears in the top-right corner as it tries switching between Analog mode and Digital mode, but the rest of the screen is completely black) and the sound from my speakers will completely cut out. When it happens, the computer won't respond to any keyboard or mouse commands, so I have no choice but to manually hold down the power button to shut it off, wait a few minutes, and restart it.
It seems to happen randomly, regardless of what I'm doing. Sometimes it happens after an hour, while I'm in the middle of playing a game or browsing the internet, sometimes it happens within 5 minutes of turning on the PC, while the system is idle. It started a month ago, and the attacks have occurred more frequently as time goes on. Now, it seems to happen within twenty minutes of start up, whereas before I could go an entire day without it happening.
My specifications are as follows:
OS: Windows 7 Ultimate 64-bit
CPU: AMD Phenom II X4 965 (3.4 GHz)
Motherboard: ASUS M4A88T-M
Graphics Card: ASUS AMD Radeon HD 6850 (EAH6850 DC/2DIS/1GD5/V2)
Hard Drive: Western Digital Green 3 TB (WD30EZRX)
RAM: Kingston 8 GB (2 x 4 GB) DDR3 1600 MHz (KHX1600C9D3P1K2/8G)
Power Supply: Antec 520W Neo Eco 520C
I also have a wireless network card, and a CD/DVD drive, but I don't know their details. If it's important and anyone requests, I can find out. All the components were bought new in February 2011, except for the hard drive and the RAM. Those are brand new, bought two days ago. (I purchased them to stop some Blue Screens of Death that also started occurring a month ago, caused by "faulty memory/hardware failure". The BSODs have stopped since I replaced the hard drive and the RAM, but the random video/audio loss hasn't stopped.)

I got my hard drive replaced a few weeks ago (dropped my laptop) and had an OEM version of Windows 7 installed. After getting home and re-installing all my drivers /programs, I used it like I normally do. Fast forward 2 weeks. I wake up and press the power button but the laptop is dead (this is odd because I usually put it in hibernate on a full charge before I go to bed). This continued to happen every day, my computer s dying overnight. Since last week I have been observing it overnight. Whether it be hibernate or sleep, my computer will turn itself on and become completely unresponsive (sounds like it's on but the screen is off. My test to see if it's frozen is to hit the 'num lock' key to see if it lights up). This event is a 100% occurrence. The only way to turn it off is to hold the power button for 5 seconds. Basically if I leave my laptop in sleep or hibernate, it will turn itself on at a random interval and immediately freeze. It will stay this way until it dies or I do a hard shut down. Also, if I leave it alone and go afk while working, it will go into sleep mode and freeze completely.

I want to change DNS address but when in "Network connection properties" I select the "Internet Protocol Version 4 (TCP/IPv4) line the Properties button is not active and I can not click it to open and change the DNS address.Also I see now that Properties button is inactive for all the other lines too.. I can't find the reason of that..Did I restrict something by mistake? or is it another problem..I'm on Windows 7 Home Professional..

All accounts (also admin accounts) on the machine have the same impact

I have RC 7100x64 connected (per cat cable) to a wireless router. Windows 7 created a home network. Router is perfectly fine and my 2 laptops automatically login into the internet. In the beginning my despktop also jsut was able to be online after booting up.
At some point (I did all updates, installed all my software) the PC does not connect to the internet anymore. Tehonly way to get online is to:
- open Network Center
- leftclick "Connections: local area connection" --> disable
- go to trouble shoot problems
- then it finds " the local area network adapter is disabled"
- I click " fix it" and it will work.
I attached the screens
How can I make it connect automatically (as it did before)? I set all services I could think of to " automatic" (IP Helper etc.). From researching I read that XP had a similar problem with SP3. not sure if it is related, but coudl an update be at fault?
Everything is up to date, Kasperksy keeps viruses away, I did not do one of the registry-cleaner tools.
Since it worked at first, one of my isntallations or updates must have done it. I also did some of the "service optimizations" from here bu tundid all of them to resolve my problem.
One could say I should isntall a newer built, but first I just want to use it before I buy the real deal in October. Second, it used to work with RC 7100 and going through all the trouble reinstalling is a hassle.
Everything else works well.

Out of the blue, I lost my Network and Internet connectivity Windows 7 gave me excellent troubleshooting tips like to check if I have a cable connected.Device manager tells me that my network adapter is working properly (Realtek GBE).When I try to connect to a network it tells me no network connection found. The machine is still configured as it was out of the box (relatively new machine - Dell XPS Studio 9100 - Windows 7 Home Edition 64 Bit). It been working fine for almost a year. I sincerely hope reformatting and reinstalling Windows 7 is not the answer to every windows 7 problem

So, we have a network of about one terabyte of storage on it. It is normally connected to my laptop, a desktop and our Playstation 3. Obviously it connects via internet with our wireless router and such but for some reason it won't connect to my laptop? I have everything except a few programs on the network (Everything from my documents to my pictures to my other programs are stored on the network)...thus not being able to access it is a HUGE difficulty

I am doing some troubleshooting and I want to completely remove my network connection. I remember with Windows XP when I did this, it would re-detect the network card and reload the drivers and settings after I rebooted.
I can disable the connection but not delete. How do I remove the connection in Windows 7 x64?

It seems like it takes several 5-10 minutes for windows 7 to realize its supposed to grant my computer access to the network. After boot up, I open the network and only see my own computer. I refresh several times over 5 minutes and finally the other network computers appear.
How do I fix this?

I am trying to download ios 4.2 from apple on itunes for my ipod touch. I have really slow internet and I am running on a Toshiba Satellite with Windows 7 Home Premium 64-Bit. The download is 346.8 MB and the estimated time starts at around 9 hours. But even after 5 hours since I start it only says the estimate is 8 hours! Then when it finally gets to 7 a little window pops up and says the network connection timed out.

Acer Aspire 7745 Notebook (purchased 10/25/2010)Win 7 HP 64-bit (build 7600) (last update 11/11/2010)Broadcom 802.11n Wireless Adapter (5.60.48.35)Since the last update, the wireless network keeps dropping its connection randomly. Windows Network Diagnostics says it can't connect. Status shows limited connection. Manual disconnect and re-connect says "Not in range" although it shows in the available networks with strong signal. Disable and re-enable causes the entire system to lock up and I have to power down. The only reliable way to reestablish a connection is to reboot or wait some random amount of time until the system decides to recognize the wireless network again.

I've recently moved into Windows 7 Service Pack 1.First thing (and foremost, right now) I've noticed is how unstable and slow my Internet Connection is; Windows 7 reports my Wi-Fi router's signal strength as "Average/Good", whereas in XP it's always "Excellent". I can't browse at all, or log into Windows Update to get fixes; the connection drops erratically.What offline tweaking can I do to fix this situation? I use a REALTEK RTL8185 54M Wireless LAN Network Adapter to connect to a D-LINK WBR-1310 Wi-Fi router.

ACER Eee PC running Win7 with all windows updates. The problem is the machine running Windows 7 Home Premium intermittently loses "internet access". Where the bars are full, but the ! shows and there is no connectivity. The other Win7 machine is set to automatically install updates and is running fine, although it seemed as though I was restoring it every week or so to get connectivity.Back to the point, the machine in question is Win7 and all available updates are installed.Bonjour service is "stopped" (but it runs fine on the other Win7 machine), TCP/IP was reset, Winsock is reset, registry/temp files cleaned via CCleaner. Zone Alarm Free and AVG are running, but they were running this morning, yesterday and a while ago when it lost connectivity again. One time I went to bed annoyed ready to set the %^&* thing on fire, but in the morning it was working fine!
I'm not exactly a N00B, but I'm dying for an explanation or a fix other than restoring every time "internet access" isn't available. Mind you, this house is full of nerds...Android phone, two iPhones, Lubuntu, Win7 Basic, Wii...all wireless and a wired Vonage that all works great.I was a member of That Computer Guy forums for a couple of years and learned a lot from the moderators and know how much work you guys do to give us this free service.
