Network And Sharing Center Doesnt't Work After Sleep Mode
Oct 30, 2011
I have Windows 7 (64 bit) on Samsung RV520 - it's a new laptop, I got it about 5 weeks ago. The problem is that after the computer wakes up from sleep mode, the Internet connection is lost and the Network and Sharing Center is not responding at all. Sometimes it does not detect any networks (neither the cable one nor the wifi connection), sometimes it recognizes them but gives "cannot connect" message, sometimes it says I'm connected, but nothing Internet-related works anyway. Either way, every time my laptop goes into sleep mode and I want to access Internet, I have to restart the system, and well.. this is rather annoying.
It's not about the Intenet provider, since on the roommate's laptop all the connections work perfectly fine.

I have realtek ALC898, part of gigabyte Z77 UD5h mobo, windows 7 ultimate 64bit. Rear jack speakers always work, sound always works. But after sleep, the front panel audio jack does not work, ie headphones silent.
Workaround 1) go to device manager, disable realtek high definition audio, then enable it, then front panel audio jack works properly. workaround 2) restart the computer and it works again.
I tried disabling sleep and using hibernate, since I read somewhere that hibernate is like a restart, but apparently it is not. Using hibernate, once it resumes from hibernate, front jack still doesnt work just like using sleep mode.
It sounds like resuming from sleep mode or hibernate mode, that windows 7 is failing to reinitialize some of the realtek audio drivers, at least those associated with front panel audio jack for headphones. So have to restart or disable/enable realtek high def audio in device manager. I have most recent realtek drivers, tried both from realtek, and most recent from Gigabyte, both have same issue. My windows 7 is fully up to date.
Am I right in this is just failure of 7 to reinitialize some drivers?

Network and Sharing Center - Open
Network and Sharing Center - Open and refreshed

I have a linksys usb600n (v2) using the Windows 7 driver from linksys. It installs and is displayed correctly in Device Manger - BUT it doesn't appear in the Network and Sharing Center as an adapter. This same device and driver were previously working just fine in this system - but I rebuilt the OS (clean install) after testing a number of security products out.
The initial install went fine - no problems that I remember - just plug in the adapter and install the drivers obtained from Linksys (Ver 3.00.01.0). I tried the same thing on the re-build and it looks fine until I go into the Network Center and can't set up wireless networking since the adapter does not appear.
SIW shows TWO (2) linksys USB adapters under Hardware/Network Adapters, but does not show the network adapters in the Network Information section.
Any ideas?

My network icon started displaying a red x about a week ago. now here's the kicker both my Wired and Wireless still work and if I hover the mouse above the icon it tells me I'm conected to my network. Now if I enter the Network and Sharing Center it tells me my access type is internet and my homegroup is Joined and that I have connection to the internet and that I'm connected by Lan but only through the full map does it tell me Lan Connection. Under Connections there is nothing listed.
Also under Change Adapter settings the only item that is currently there is my Bluetooth network. Please help more annoying than anything. And yes the internet works I'm on it right now.

What is the Networking and Sharing Center?
Simply put, the Network and Sharing Center is the control panel from where all networking settings and tasks can be launched in Windows 7.

In Control Panel, when I click Network & Sharing Center, it freezes and does not recover. I am logged in as Administrator. I have no Internet connection; the taskbar icon for Wireless is greyed out.

I want to add additional icons to the 'system32pnidui.dll' file. That's where you pick which icon you want to represent the active named network in the Network And Sharing Center. I did a search in this forum on 'network icons' but didn't find anything. Aside from all the permissions restrictions what app can be used and what kind(s) of files will work in W7? I have lots of .png images that I would like to use if they will work. Lenovo T500 W7 Pro-64 Current Updates.

ecently I have been experiencing this one issue over and over again, my internet would stop working in the middle of me using it. I would try to click on the wireless icon in the notifications bar and nothing would happen so I would then try and go to the Network and Sharing Center through the control panel and when I click on Network and Sharing Center the explorer that I am in freezes.I have looked on here to see if this is a common occurrence but I haven't been able to find anything similar to my issue.

Everything works fine but every time I restart windows it takes a good 3-5 minutes for the 'Network and Sharing Center' icon to "load". Basically it has that circular loading icon hovering over it like it's loading something, and sometimes it has a red cross over it. During this time Firefox won't load and MSE disables real time protection until the network center says I'm connected.

I have recently (After yesterday's Windows Update) gotten a weird problem.
As I log in normally to my computer, the Network Sharing Center doesn't respond, nor does the icon down in the taskbar. I have tried the solutions you can find by googling to fix this - none helped.
That is not everything, every application that wants to use Internet connection freezes as they try to do so.
I got it fixed temporarily by using the System Restore to restore the system to the point before the Windows Updates were applied, but that is not an option anymore, because the restore point is no longer there.
Windows does not let me uninstall updates in Safe Mode, and as Windows Update accesses Internet to do so - it too freezes during a normal login.
Any suggestions?

My problem is on a Media Center machine where I recently upgraded Motherboard and processor. I have the following setup on the machine:
MB: Asus P8H77-MLE
CPU: Intel i3 2120
2x2 GB Kingston ram
OCZ Agility 3 SSD 120 GB
1,5 TB WD Caviar Green
Asus P7131 Tuner
TERRATEC Cinergy DT USB XS Diversity
Hauppauge! WinTV-NOVA-T-Stick-Diversity
Hauppauge! Smart CI USB
My previous setup was with a AMD 240e. I use Microsoft Security Essentials for antivirus and have firewall turned on. The Media Center machine is on for 24/7 on sleep mode for recordings or turned on for showing recordings. Since the upgrade I have BSOD most times after it is turned on after sleep. The STOP occurs 4-5 minutes after the wake up either the wake up is initiated from a recording or from user. I even see BSOD occur in the middle of the night where I have no recordings or other activity. I have made several new install and tried to exclude the SSD and install a 32 bit Win7 - but the BSOD still occurs 4-5 min after awake.

I have a 32 bit Windows 7 Lenovo Thinkpad L412. In the past few weeks I have re-imaged my hd to factory state (as I do often).After a few days it begins to go into sleep or stand-by mode after being left idle for around 5-10 minutes. It does not turn off, or actually hibernate, it simply goes to the user log-in screen prompting for a password to return to the desktop.I have no idea why. I am not a noob or anything, I have checked the power options, and power manager and changed all settings for sleep/hibernate/standby to never, including the power plan I am on.I can find absolutely no reason why it is going to the log-in screen.HOWEVER, I think it only starts doing this after I have opened and set-up Windows Media Center. After putting my TV tuner in via USB and setting up my TV in windows media (which works fine), the comp begins going to sleep after 5-10 minutes.It will do this indefinitely, even if I take the PC tuner out or close WMC, or restart.

Windows 7 N&S center is really slow. I have no idea what's causing it.Symptoms not present when I connect to my wireless router.But when I tether (get a connection from a USB device) the N&S Center stops responding for about 10 minutes.At some point, it will come up with the "Public Network?" box.How can I debug this?Even after the network is initialized, the N&S center is still very slow.I assume it's doing some automatic something or other that keeps pinging this, that or the otherThe USB device would serve an internet connection that has a reasonably high latency.Lots of network tools seem to slow down, especially while the connection is configuring itself. This is probably because all of the services involved are interlinked somewhere, and are waiting on the same mutex to be released or something.

I've bough a Dell Inspiron 1564 with Windows 7 home premium x64 last month and everything was fine until a few days ago, when sleep mode stopped working. When I close my lid and open it up after some time there are 2 things that might happen:
1. The screen is just black, all the buttons are lit, I hear the fan, but no reaction at all. So I just forcibly turn off and turn it on again.
2. After opening the lid, nothing happens, when I try to turn it on, it loads up, but informs me that windows has not shut down properly last time (or something like that).

I have a Windows 7 laptop connected via a WRT54G2 wireless router to an XP SP3 desktop. Both the laptop and desktop can see shared resources and both can connected to the internet.
In the Laptop's Network and Sharing Center, however, things are not correct. The Laptop has two connections to the router, lan and wireless. The lan's connection appears OK, but I cannot generate a map. I get "Windows cannot discover any computer or device." The wireless network is public.
I don't know why and I don't know how to change it. Also, when I try to create a new network connection, the laptop sees only a WRT160N router (which I don't have; perhaps I did a while ago, when the laptop ran Vista). No place to add a new one.
I have Cisco's Network Magic and it can correct see everything, including the right router.

So I purchased a Razer Naga because I loved the idea of 12 buttons right on the side for my thumb and since I work at home and pretty much just sleep, eat, and work around this computer I only put it on Sleep Mode. But when I moved my mouse around the next day it wouldn't start up. So I unplugged it and took it back got another one. Same problem occurred. Check to see if it would wake the computer from standby and it was checked. So then I moved on to updating the Firmware. Problem still occurred. So I'm wondering is this Razer's fault or perhaps my Motherboard not being power up enough? I do have a 5 year old power supply on my high end computer that's 550 watts due to my 1000 watt dying.

I had a problem about ipv6 on windows 7 for a long time. I have a ipv6 & ipv4 dual stack network. Every time I wake up my computer, the ipv6 cannot work. The appearance is that I can't ping and access ipv6 website. But after some research, I realize that only the DNS part is broken. When I ping the ipv6 site like ipv6.google.com, it tells me it find no host, but if I use nslookup, I can find the ipv6 address. And the following are my tries:
ping ipv6.google.com -- not work
ping 2a00:1450:8001::68 -- does work, the ip is the ipv6.google.com address
ping -6 ipv6.google.com -- does work like the above

How a machine Windows 7 or XP once goes to sleep/hibernate mode, can be identified on the network to do a Wake-On-LAN. Because the machine is shutdown, the ping does not give a response. In a DHCP environment, when the machine goes to sleep mode, the ip is released so not necessarily the machine can be identified with its IP.

As i've mentioned in the title my Realtek Network connector is missing and Windows 7 cant locate it.This happened after my computer went into sleep mode for some odd reason. And whenever i try to re-install my driver it says:
"The RealTek Network Adapter/Controller was not found. If Deep Sleep Mode is enabled Please Plug the Cable".
So how can I get it back? So far I've tried:
-Removing my RAM for 10 mins and after that for another 1 hour
-Resetting CMOS from Motherboard
-Re-Installing Windows.
My Motherboard's model is : GIGABYTE GA-H61M-S2V-B3 with 1 x Realtek RTL8111E chip (10/100/1000 Mbit).

I have a PC running Windows 7 with 3 HDs(not partition, different HDs).2) I used Windows 7 to create an image of the OS HD(C and placed it in D.3) I used the image once or twice so I know it's a god image, and it's notcorrupted.4) Lately I've been having performence/computer-gets-stuck-issues and Iuspected the HD(C because my RAM is fine, and finally windows alreted my that that HDis failing.(plus, I can hear "ticks" of the HD's nittle trying to read whenever the computer got frozen for a sec or two.5) I replaced the HD that was C: with a new one, and installed Windows 7 again.6) Tried to restore using the image and the recorery system said that it needs to formatthe drive that it's on(makes sense) and ordered me to perform the restore throughthe windows installation disk,7)I did. but I get a similiar error that ordered me to restore with an image but using a windowsinstallation disk(and I got to this error using the instllation disk)How can I make the image work?the only problem I can see is that the image was taken off a a different HD
