Wifi Connectivity Lost After Sleep Mode?
Dec 21, 2010
I have Windows 7 on a Dell Inspiron 1545. Most of the time when I put my laptop to sleep and restart it Wifi network connectivity is lost and I have to click the 'Wifi Signal' icon in the system taskbar and click on my network name and click connect to regain connectivity. I have gone to 'Power Management' tab and cleared 'Allow Windows to turn off this device to save power' option as suggested by most posts but it has done nothing to help me. But sometimes even after a long sleep the laptop immediately connects back to the network and sometimes even if I just close the lid and open it after a few seconds network connectivity is lost.

Machine: Dell XPS17 laptop (702x)Windows 7 home premiumWifi adaptor: Intel Wifi Link 1000 BGNRouter: Belkin F5D7634-4 802.11GReconnection takes 3 or more minutes to establish after sleep. Tried all the on-line advice e.g setting power scheme to max power; unticking box in adaptor settings 'Allow computer to turn off this device'.Tried to update drivers for wifi adaptor but the update process says I have the latest drivers. However Dell's driver site analysed my laptop and says there is a later driver for download. Tried installing this but was stopped by message saying it wasn't authenticated/certified so terminated.

I am using Acer Travelmate 8204WLMi laptop running the latest RC build of Windows 7. The internet connection is lost on both LAN adapter and WLAN (3945ABG) adapter when laptop is restored from a 'sleep' mode. I have disabled 'Power Management' of each adapter via the Device Manager. I have updated to the latest set of updates.
Disabling and re-enabling LAN or WLAN adapter to restore connectivity does not work (as it does in Win-XP). I have tried to 'log off' and log back in but this does not work either. I have discovered that the only way to restore connectivity is to re-boot the laptop.
It would appear that there is an issue of the Windows 7 code to correctly manage the LAN/ WLAN adapters. Has anyone else come across this problem?

My wifi turns off when my computer goes into the sleep mode. I have to hit F8-- turn it off and then turn it back on again. How do I get it to stay on all the time?

I have the TP-Link USB Wireless adapeter (TL-WN722N) It always reconnects after sleep mode or I have to do it manually and it takes a long time to reconnects all the time?
***DO NOT say to uncheck " Allow the computer to turn off this device to save power" option! This DOES NOT work for me and it has no effect whatsoever!***

I recently did a fresh install on my gf's computer as it was suddenly unable to establish an online connection. The error showed in the connection status as the small yellow warning icon at the top left of the connection status icon, not the big red X that appears when the machine isn't connected at all.
Here are the specs:
OS: Windows 7 Ultimate x64
Mobo: Gigabyte GA-X58A-UD3R Rev.1
CPU: Intel i7 950
RAM: 12GB Corsair Dominator GT 2000mhz
The system is also not overclocked.
After trying many things (reinstalling network drivers, flushing DNS, trying a different ethernet cable, restoring all network settings to default) I gave up and did a fresh installation.
After installation, I installed all the usual official drivers, then performed a Windows update, but only the important updates. The connection was back! I then decided to install some optional stability updates, and after reboot, the network problem was back.
I did a system restore to before I installed the optional updates, but the problem persists. I have no idea which optional update is causing this, or which one to remove first to avoid creating more errors.

I had my HTPC up and running last night, watched a movie, turned it off and went to bed. When I woke up this morning I found that I couldn't get any sound while playing videos through my web browsers, thinking it might be a video card issue I first checked some of my movies, but they also wouldn't play with sound so I deleted my nvidia files and reinstalled them. No luck, on one restart I lost my internet connection with my router. If I look inside the Buffalo's settings, I can see my HTPC's IP address (after running ipconfig /all on the htpc) I did a system restore but that didn't work. I even went so far as to do a clean install of Windows on the HTPC, but that also didn't work. I keep getting the yellow triangle and the message "unknown network" The HTPC tells me to check my router, which I have restarted a number of times unplugging the cable modem and the Buffalo. Turn on the cable modem get it online, then plug in the Buffalo, but nothing works. I have tried switching ethernet cables, ports, but no luck.

I am having a problem with my Toshiba NB505 Netbook - running Windows 7 Starter. I can connect fine at home to wifi- and also at my local public library. However I was unable to connect at a motel I was at recently and had the same problem when I visited a different local library.To be more exact, I was able to connect ok at these 2 locations - but there was no internet access. From reading, I suspect a 'DNS' issue of some sort, but I don't know how to go about remedying it.

On the right hand side of the taskbar I have the icons for battery life, volume, internet connection, etc. When I used to put the mouse over the internet connection it would show me who I was connected too (SSID) , signal quality, and speed.I began having some issues so I had to remove my Netgear connection and then reconnect.Ever since I did this all that shows up now when I put the mouse over it is now only says: Netgear and Internet access.How do I get the information back. It shows up on my desktop, but not my laptop.

Whatever modem/router I use (except my old 2Wire that died in Dec. 2010), I lose connectivity after I resume/wakeup. The tray icon says "connected", but my browser (Firefox) or my email client (Thunderbird) say "no"!

I had Windows 7 32-bit running on a Dell PC. About one week ago, I noticed Internet connectivity was gone and that there was "limited connectivity" as I was now connected to an "unidentified network". The other systems on the network are still connected and working perfect; the problem is isolated to this one system. The network uses a static IP scheme. "IPCONFIG /ALL" shows that the IP is assigned, is included on the correct subnet and has the correct gateway and DNS information. I've tried a host of solutions suggested on forums; from "route delete 0.0.0.0" to disabling my firewall to configuring for a dynamic IP. Nothing has worked. Reluctantly, I resorted to a fresh install as I began to worry that I may have picked something up. I completely wiped the hard drive and did a fresh Windows 7 32-bit installation all only to have the same problem. I assume that the NIC is functioning as it accepts all IP settings.

I'm trying to fix my girlfriend's Windows 7 laptop after she had a virus/malware infection. I'm pretty sure we've successfully cleared the virus (an updated/full scan with Malwarebyte's Anti-Malware in safe mode comes up clean). However, we have had no Internet access since the infection. The wireless router/connection itself is fine (I connect to it daily with my laptop, as I am to write this post) but her laptop won't connect to it, we can't browse any web pages.I may have made the problem worse in trying to resolve it. I stupidly followed the advice on a forum for some registry edits for Windows XP--deleting WinSock and WinSock2 from the registry and then restarting the computer in hopes they'd re-register themselves. Unfortunately, WinSock2 re-appeared but WinSock did not. I'm wondering if this has created a new problem (or compounded the problems we were already having).In diagnostics, we currently get the following report: "Wireless Network Connection doesn't have a valid IP configuration." I just ran an ipconfig in the command prompt and got the following results:
Windows IP Configuration
Host Name . . . . . . . . . . . . : Elizabeth-PC
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No

My adapter is always gone from resuming from sleep. I know it was working before. Just changed my ram and bios settings from a fresh build. Went from Corsair xms3 to G.Skill Ripjaws.
I am having this same issue with my newly built pc. The drive running Windows 7 is from a laptop where the mobo died. I am using it in AHCI mode because my case has a front hot swap caddy.
I have a Gigabyte Z68X-UD3H-B3 mobo and after installing and uninstalling drivers, software, changing settings, removing ram, changing power options to maximum power for pci card and wifi, turning off hibernate, restarted, rebooted, updated all drivers from Gigabyte, chipset drivers, etc. I have unchecked "allow Windows to turn off this device". Restarted and tested and I get the same issue. I have unchecked this box in all of my networking devices too including, 802.11n Wireless Lan Card #2 and Microsoft Virtual Wifi Miniport Adapter. Also, uninstalled and reinstalled these and updated drivers from my disc that came from Gigabyte as well as driver update from the Gigabyte website.
Nothing I do will turn on my wifi card after sleep. Windows will not see a network adapter. Everything works fine after restarting though. I have S3 enabled in bios as that is what I want. I have case fans that I don't want to hear with no option to turn them off. Otherwise, i'd be fine with S1.
Is this just not a working feature? I've read that sleep is an ongoing issue with Windows, but my pc sleeps fine. I just want to be able to put my pc to S3 sleep and resume with a working wifi card. There must be a key setting i'm missing because i'm sure it was working with my last set of ram.

Wi-Fi does not reconnect after login / sleep / reboot. It always prompts me for the password. In "Manage Wireless Networks", it is set to "Automatically Connect". But somehow Windows "forgets" the password.
I'm running Professional x64.

power off and unseat the video card, re-seat it, and power back up...
Windows 7 pro Intel Core i7 870 Processor ATI FirePro V4800 Motherboard GA-P55A-UD3Without doing the above steps, just get black video screen
Would this be a software issue, problem with motherboard or video card?

I bought a new notebook running windows 7 64 bit a couple of months ago After running a full system scan with Kaspersky anti-virus a couple of days ago I now have a bug with sleep mode - After going into sleep mode, the user with my picture icon is locked meaning that I can't enter my password to log back in - the password box doesn't show.With the ASUS face recognition scanner I'm logged back in, but everything is 'buggy' e.g. if I click on the start button and hover over that entire area it goes into sleep again, or if i click on the bookmarks on chrome it doesn't show them, instead it click on an actual site within the bookmarks.After going into sleep the only way to enter and return to a normal state is to click the 'switch user' whereupon, my user picture icon reverts with the password boxI have tried a system restore but this didn't work.

Since a few days my PC developed an unusual behaviour: it goes to sleep mode at random intervals ! sometimes it does that at windows start up for several times...
I had microsoft security essential installed and read on some forums that it could be the reason for this problem: I unistalled that. Then I run online scanned from ESET nd Bitdefender: all clean.
Then I installed avas free edition (as I was without any anti-virus software). Did a complete system scan with no problem. I messed up with the power consumpion settings with no results.
The only solution I could find was to use the software "Dontsleep.exe" which I found googling around: it works ! I looked up all the running services and application at windows sturtup and disabled a lot of them with no results.

So this might be the wrong place for this thread but I didnt see a computer specific section so i picked this just incase it is related to my windows. Anyway the problem i am having is that every so often, more often then not actually, when my computer hibernates from inactivity, it cannot be woken up. I click the mouse, press everything on the keyboard and nothing will happen. I even try pressing the power button yet that does nothing. The power button just keeps blinking as normal when in sleep mode. I also tried Holding down the power button, in hope to force shutdown the computer but that did not work either. The only way anything happens is if i unplug the computer and then plug it back in. Unfortunately i know thats really bad for the computer but i dont really have a choice.[CODE]In addition, i have restored my computer to factory defaults, aswell as installed all the latest drivers

After putting my computer to sleep, upon waking I receive an error code, which should be present in the dump file. I closed the error window before copy pasting it in here. I will update the post with the error information next time it happens. This only happens when putting my computer to sleep. Hibernate and shutdown do not have this problem, and I have not received any BSOD's during use. This has been happening for about 10 days. My memory set up is kind of strange. I have 2x1GB 1.8V ram and 2x2GB 2.1V ram, both DDR2, and both running at 2.0V. I didn't want to overvolt the 1.8V ones too much. The timings are slightly loosened on the 2.1V ram to match those of the 1.8V ram. I have run Memtest86 with no errors. My hard drives have also checked out fine.I have my q6600 overclocked to 3.0GHz, with a voltage increase, CPU-Z is saying it is running at 1.408V. I have run plenty of Prime95 tests. No stability problems, and temperatures are always acceptable. I have had it at this overclock for 7 months, ran at stock the previous 4-5 years. My GTX 460 is overclocked as well, always has been stable as well, with temperatures plenty low enough.

My pc is shutting down more and more frequently so that it now happens every time I close the lid for sleep mode. In Event Viewer there are numerous "Event 41, Kernel Power" warnings.

I installed 7RC a couple of months ago. Since then whenever my pc sleeps I can not wake it up. It used to wake up fine in XP. To get it going again I have to cold reboot or pull the plug. When it comes back up everything I was doing is still there, I just have to enter my password. I think I have all the settings right but if someone could run me through everything that needs to be set I'd be really grateful.

I am not savvy in this kind of stuff. My husband has a home built computer that runs our tv system with windows media center. He had to leave on a military deployment and right before he left he had to reinstall the OS. Since then the computer refuses to wake from sleep mode. I have to scram it to get it to come back up. Since we run the media center it ought to wake up to record automatically, but it isn't doing that either. I've checked all the power options but that doesn't seem to be the problem. Although, at this point, I really have no clue.

From time to time Windows 7 will not go to sleep (only the display will turn off). I have searched various forums and tried the following fixes: I have already made sure that network adapters are not allowed to wake up the computer. I typed "POWERCFG -ENERGY" in the command prompt (as administrator) and an energy report was generated, which reported this error: System Availability Requests:System Required Request The service has made a request to prevent the system from automatically entering sleep.
Requesting Service Spooler Opening task manager, I see a process running called "splwow64.exe" -- is this the spooler preventing the computer from sleeping?

To prevent my computer from going out of sleep mode by itself I have to unplug my ethernet cable, that's 1 problem but I don't really care.
The other problem is when I come out of sleep mode, my DVD player opens by itself, I close it, and it reopens.
