Home Network Intermittent Internal Outage?
Oct 11, 2012
I have a wifi home network with several devices (laptops, all but one are Windows 7, and a wireless printer) connected through a dsl modem/router (a NexusLink 5631) to each other and to the internet. The laptops can all access shared folders on each others' hard drives, and all can print wirelessly to the printer. Until ... after a few days of happy camping suddenly none of the devices can 'see' each other (can no longer find any other device on the network) and none of the laptops can access the wireless printer. However, internet access is never disrupted; each laptop can still happily surf the net no problem.I am somehow able to rectify the problem by rebooting the dsl modem/router, updating the connection settings on the printer, going back and doing it again, turning round three times and twitching my nose ... after fiddling for a while to no good end everything comes back as it should. And I don't know why.I have contacted my dsl provider (Frontier, in Ohio) who own the modem/router and they say it's nothing to do with them. As long as I have internet access they're not interested.I called them because, interestingly, all this only happened when I switched from my old) cable provider to the dsl provider. When I had the old cable modem/router this issue never occured.

just upgraded my vista 64-bit install to win7 home prem 64-bit.
everything has been working great except for an internet/network issue. at random times, all of a sudden the icon in the tray gets that yellow exclamation point over it and says there's a network issue and no internet available. it's like that until i disable and re-enable the network adapter. there are other systems on the wired router and they're still working fine (vista and xp machines).
the strange thing is it *seems* to only do it when i start doing more than one thing at the same time. i.e. trying to watch Internet while playing an online game. or, downloading a pdf while streaming music. all of a sudden, all internet goes down (other computers still working fine though). once i reset the adapter, all is well.
any ideas here?

The problem I've been experiencing is my local area connection "network" switching... if that makes sense. What seems to be happening is when i connect my desktop pc (via ethernet) and laptops (via wireless) to the new modem/router ( either netgear DGN2200 OR linksys WAG160n), the network and sharing center will say im connected to network 2 and only provide internet access to my desktop while the laptops have no internet acess, and after numerous disabling and enabling the wireless on the laptops and doing power cycles on the modem/router, internet access is granted on the laptops... then however, no internet access on the desktop (happens on both modem/routers).
Then by some act of god, there is internet connection on desktop and laptop, and when I check the network and sharing center, it would say I am connected to network 4, but thats not all, because when I turn my pc off overnight for when i sleep, and turn it back on, I'd still be connected to network 4 and have no internet access on desktop or laptop and what I mentioned above happens again and I'd go through all the general trouble shooting stuff and randomly it would work again. After speaking to support from both Netgear and cisco... I think the problem might be with my network card?

We have 2 wireless laptops & 1 hard wired tower (all onWindows 7) in a home network. (All hardware are new this year) The laptops have intermittent internet connectivity yet do not lose the network connections. I have upgraded both the Motorola modem and Linksys router to Windows 7 but it did not resolve the issue.

For the past few days, I have been on a intermittent wireless connection. Under the wireless network icon, there's an ! mark, I tried to solve it using Microsoft diagnosis, but it didn't work. I switched off Microsoft Miniport Adapter too, didn't work as well. I Pinged my own connection using Command Prompt and the results were fine. For a limited random number of sites, I am still able to access. I tried Torrenting and it still works too.

I have an intermittent problem with networking my desktop machine to my laptop. Sometimes after I hibernate my laptop and then wake it up, I am unable to access my shared drives on my laptop from my desktop. I am always able to go the other way (access shared drives on desktop from laptop. When it does this, even reboots of both machines don't help.
I just asked Windows 7 to diagnose and I get this. Usually after "messing" with the network settings, log offs, reboots, who knows, it usually starts working both ways again until some later hibernation restart of laptop. I wish I could pinpoint some common things that cause it but I just can't figure it out. Any ideas?

5 month old Dell XPS 8500 Win 7 64 bit Pro as main computer connected by Wired Adapter, Upgraded Gateway 5632E also running Win 7 64 bit pro as second connected by Wireless. Both running Kapersky successfully. no network problems for 5 mo.
Both were successfully linked using homegroup. Had to take Gateway to a remote location to do a business demo. While there had to link to a local public WiFi. While connecting made mistake and left homegroup.
When Gateway returned to homebase a few days later it was fine, had no problems finding wireless but could not see or rejoin Dell machine homegroup. It would let me set up a new homegroup.
Went to Dell box and found 1) homegroup no longer existed, 2) router and network and wireless printing no longer found - Red X on the taskbar) even though internet was still working fine.
Took nearly a week of trying differernt fixes, on adapter- off adapter- different adapter reboot network, router, even updated router firmware (Yes I went through every ipconfig reset, renew, redecorate etc. I've used netsh functions to try to get evrything to reset. Changes services.msc settings per other posts. Finally in desperation, deleted every sub key in the registry related to network locational awareness and got the Dell to find the network, let me set it up as a "home" network and then even see the invitation to join the Gateway's homegroup.
Then I hit a wall- when I try to join- Win 7 says I can't join the homegroup because the network is not a "home network". Of course troubleshooting is useless and goes into an endless loop. Have searched in desperation for any way to make Win 7 return to a clean slate so it can sense that it really is on a home network without success. Applied the fix-it and hotpatch for when Win 7 gets stuck in public mode. No joy. Deleted the hide wizard subkey as suggested elsewhere. No Joy. Gut feeling says problem must lie in the NLA or peer networking somewhere but where?
Does anyone know of a method or set of steps (short of a clean reinstall of Win 7) to completely clear every thing the OS knows about my network and force it to acknowlege my network is a home network? Is there a registry hack that will clear the problem?
I know I could abandon the homegroup and do conventional file/print share but I am concerned that using that solution won't last as whatever is screwing up the homegroup could eventually screw regular sharing and then I'm back to reformating/reinstalling. I'm just about ready to join the Apple folks so I never have to work on Windows again.

My desktop computer loses connection regularly and I cannot locate as to why. I have many other devices throughout the house at various locations which maintain a connection fine. When the connection drops it still displays I am connected, but there is clearly no connectivity.
I've tried toggling between two devices, one an eternal PCI adapter and the other a USB adapter. I get interruptions on both, so my conclusion is there must be a setting causing this. The desktop has been moved to other locations just in case of interference, and I've tried channel swapping as well.

I'm reimaging one of my home systems that I intend to use as a "sterile" system (I will visit very a very limited selection sites on it, such as banking sites). I'm considering establishing the network location as "Public" instead of "Home", rationale being this would help prevent cross infection from other computers on my home network if they get a worm or virus. I do have friends that come over and hop on my network sometimes and who knows what contamination their systems have. Is this being overly paranoid? Will it cause annoying problems for this sterile system or other systems in my home network? I don't intend to share anything on this system with other computers on my home network. Seems to me that this ought to be the recommended setting for any computer always ... you can always share files using a USB drive if you really need to. Thoughts? Again maybe I am being overly paranoid. Back in the day there used to be worms that would look for ways to hop from system to system over the network, maybe that's much much harder these days. I do have a router between the DSL modem and my home network and I do run Norton Internet Security on all my systems?

I'm the net admin for a small network. One of my users has a problem that has just started today, apparently. When emailed a link to a file on the internal network, from another user on this same network, clicking on the link simply gives an error about it not being allowed. (This operation has been cancelled due to restrictions in effect on this computer. contact your system administrator.)
All users are admins on their own local boxes. This user could perform this function prior to today. There is no problem with the structure of the link, nor with security for the file in question. (I first verified that the user has access to the file, and he does, he can navigate via Windows Explorer to the location, open the file, even has write access to that location)
Even when creating an email, and not using a masked link, but a full UNC path, the 'Crtl click' to go to the location results in the same error.
I tried removing spaces from the file name, same error. I tried typing out a link to a share (not a file), one that has no spaces and I know he has access to, same error.
This represents a significant problem. My users need to be able to send links to internal locations and files, and not attachments (for multiple reasons).

I'm having difficulty trying to get my new Windows 7 pc set up to share files across my existing home (wired) network which consists of 1 desktop pc running WinXP and 1 laptop running WinXP.I want the 'C' drive on each of the 3 computers to be shared. I've had the 2 Windows XP computers set up and working like this for several years without a problem but I can't seem to get the 'C' drive on the Windows 7 computer to do the same.All 3 computers have the same workgroup name and none of them require passwords to log on to Windows. There are no problems with the firewalls on any of the machines.On the Windows 7 PC when I right click on the 'C' drive and select the 'Sharing' tab, I have set this up to be shared and when I click on the 'Advanced Sharing' button there is a tick in the 'Share this folder' box, the 'Share name' is 'C'. If I then click on the 'Permissions' button, this shows a 'Group or user name' 'Everyone' and this group has Full Control, Change and Read boxes ticked. As far as I can see there is nothing more I can do.
However from my Windows XP computer, when I go to My Network Places and double click on the icon for the Windows 7 'C' drive, I get the message "\Computername is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.The network path was not found"I've subsequently set up a sub folder (of the Windows 7 'C' drive) for sharing by right clicking on the folder, choosing 'Share with' and then selecting 'Specific people'. I then set up a group called 'Everyone' with read/write permissions. Now I can navigate to this folder from my 2 WinXP computers.

Unable to see home network computers in Windows Explorer Network screen.
I have a home network with 2 laptops and 1 desktop. The desktop I use as a "file server" in that all work done on the laptops is stored to the desktop. The desktop computer name is HAL. One laptop is fine and sees the network. The other just stopped seeing it; rebooted the laptop; rebooted HAL; did a number of refreshes without any luck. I opened EXCEL and found a worksheet that was listed that I knew was saved on HAL. Was able to open the file and when I tried the SAVE AS I could navigate through all of HAL just as normal. Went to Windows Explorer and still no HAL listed as a COMPUTER on the NETWORK. I have a internet connection so I know I am making it to the router at least. And when I check NETWORK AND SHARING CENTER it shows an active home network. The laptop is running Windows 7 Home Premium Service Pack 1 Build 7601.

Home network with Wifi and ethernet. Using 3x Notebooks and 3x workstations. One of the workstations (W7 ultimate) keeps changing between Public and Home. When this happens, the internet connection dies. I cannot see other workstations either when on public network. Workstation using wifi. Does the same on cable. When it changes to Public, it disconnects from the internet and I cannot get to the router even though it has the workstation has an IP(DHCP or static). Default gateway and subnet is correct. TCP v4 is being used and nothing else is enabled.
Why is this happening?
- I have tried DHCP as well as Static addresses
- Reconfigured NIC(Netgear WG311T), uninstalled and reinstalled it.
- Removed Wifi connection and re-added it.
- Changed auth type, encryption type and keys to connection
Have I covered everything? The only thing different is that I installed a new router - Duo Plus 300wr. It cannot be the router because all the other notebooks connect to it wireless and so does my iPad, Android device and tablet...so it rules that out?

I made the huge mistake of booting my custom built machine during a storm and as luck would have it, the only time that the power was lost (for about 2 seconds) occurred at that time. Now my machine will not boot. Startup repair comes up and tells me that it could not find the problem and I must shut down. I have tried restoring, mem tests, hard drive tests, reseting my mobo to failsafe settings, booting from the windows 7 recovery disk, booting off of the original windows 7 install disk, forcefully kicking it and crying. Nothing has worked, however. No matter what method I use, even when successfully completed, I am still faced with the startup repair error. I built the PC myself, so I'm not a complete fool when it comes to computers.

I am hooked up to a UPS, but after that runs out and I am away, I sometimes need to remotely logon - in which case I need the computer on. If I need to change something in the BIOS, please give specifics of how to do this as I have looked in there and found nothing related to this.

This HP computer is running Windows 7 - 64 Professional, version 6.1, build 7601 Service Pack 1. The last time I had a normal start up was last Saturday after turning off all the computers and unplugging due to thunderstorm activity in the area. Yesterday morning, Sunday, we had 4-5 momentary power outages where the electricity pretty much flickered a few times, then stayed on. This computer did start up, but the start up process took approx 20 minutes.
I restored the computer to 3 days prior with no noticeable difference, ran defrag with no noticeable difference, and ran chkdsk, which did make a difference. The 1st start after the chkdsk was a normal quick start, then subsequent starts take approx 3-4 minutes, so it has slowed down again, but not near as bad as the original problem. The start up goes as follows:
1.) The normal Blue HP start up screen for approx 20 seconds, then,
2.) The windows graphic with the changing colored "windows" on the black background, then,
3.) a completely black screen for approx 2-3 minutes with minimal flashing of the HDD light, then
4.) proceed to Welcome to Windows screen where everything loads and the HDD light is pretty much steady. Within 30-40 seconds of getting to this point the normal desktop is up, icons are loaded, and computer is ready to use.
My step 3 noted above - the black screen, is usually 15-20 seconds max, so it seems whatever the hangup is is occuring during that time. After the start up is complete everything works normally. There isn't any abnormal use of memory or CPU usage.

Aside from the surge itself, what other negative effects could arise from experiencing an outage while multiple programs are open and running? For example, if I lost power while regedit was open, could it change or possibly cause damage the registry itself? The machine in question is currently running Win 7 SP1 64-bit.

There was a quick power outage and the computer was forced off. I rebooted and now after the windows logo there is a gray screen that remains a very long period of time before the desktop appears. I am able to move the mouse but that is the only functionality I have.

I have been having a serious issue with my PC. The PC will boot up without incident, but if I try to access explorer or the OS, it will slow to a crawl and eventually freeze. I have encountered this with firefox, the start menu, and when trying to access the task manager. The problem is consistent, occuring everytime I start the machine. Usually within the first few minutes of a boot-up, Windows has frozen and I must force a hard reset.
The only thing I can think of which may be the cause is a power outage which occured in the night. When I woke up, the PC was off and the problem began as soon as I booted up. The PC was plugged into a power strip which was not tripped by the outage.
I can boot up in Safe Mode, which delays the onset of the crash, but doesn't stop it. I have tried using system restore by accessing the menu during start-up (F8) but the system restore always fails at the very end. Looking at the inside of the PC, there doesn't seem to be any visible damage (that I can detect) and at no points does anything seem to be giving off any excess heat.
When I press CTRL+ALT+DEL in an attempt to access the task manager, the screen goes black and the cursor turns to a wheel. After several minutes, the wheel will stop and a prompt will appear stating "The logon process was unable to display security and logon options when CTRL+ALT+DELETE was pressed. If the operating system does not respond, press ESC or restart the computer by using the power switch."

Yesterday, there was a short power outage which caused my computer to force shut down. When I turned it on, the screen resolution was off, so I managed to fix it by hardware (the auto button on my monitor) since software-based fixing didn't work (which has managed to solve this problem in the past, at least I think it was the same problem). Anyway, after I did this, the icons were strange; bigger than usual, not e.g. 128x128 but rather 140x128 (that isn't the exact size but they were higher than they were wide). This is quite annoying. The circular icons have become ovals and the square icons have become rectangular. By the way, the same thing has, I think, happened to the taskbar as well. It's harder to tell with things other than icons, but it's visible. So basically, everything is slightly higher than wider than it should be, not only the icons.

I literally just built this today and was able to enjoy a very fast boot up speed with wim7 64-bit installed on my ssd drive but the power cable of course found a way to get unplugged from the wall and now the it takes an extra 20-30 seconds in order t boot up (at the "windows starting" ) screen. Right after I turned it back on the computer wanted to go into system repair and then it reset the pc to the back up that I had just set,
Is there anything I can do in order to get it too boot up like it was at first?
