Asus P5KC Intermittent Connection Loss
Oct 7, 2009
I have a problem where my Internet connection will drop at least once a day. I have Windows 7 Business x64. It will first simply stop working, as in it looks like it's connected, it still has a public IP but I can't ping out and no browsers work, nor any games etc (you get the picture). If I try release/renew it'll either hang or give me a 169-address. To fix it I have to reboot my computer and it starts working again.
I have an Asus P5KC motherboard using the Windows 7 Windows Update drivers, and it's been like this pretty much since the start. I've turned off all power saving modes everywhere I could find and any sort of hibernation settings, and still it'll cut off almost always once a day. (I have a VNC server so I can log on from work, so I can tell when it 'crashes'.)
What's funny is that it often doesn't happen when I'm on the computer, it's mainly when I've been gone for a bit. That's not to say it hasn't happened when I've been at it, it's just more uncommon.
It's setup to a switch which in turn is connected to my modem. What's telling me that it isn't neither the modem nor the switch that has the problem is the fact that I have a mediastation which doubles as a webserver also connected to the router and it has never once cut out. I've tried switching the ports on the switch (ha-ha) to no avail.
I've been thinking about installing the Vista x64 drivers from Asus but I'm leery of trying because I don't know how similar the two systems are.
Is this a general issue with this board? I'm getting really sick of this problem. Hope somebody can help.
Also, I'm sorry for not posting this in the megathread we apparently have but I couldn't bear slogging through 43 pages of white noise and hope that my post wasn't lost at the tail end of it. There are so many issues being handled in there that I can't make heads or tails of who has the same problem.

Verizon Fios, Actiontec Router. Windows XP machines (wired) (2) never any internet loss whatsoever. Running the wireless from the Actiontec and also a Linksys that is on one of the ports. (distance issues) The Linksys always syncs up and both wireless systems work 100% all the time with either XP or Win 7 laptops.
Here's the issue: two wired desktops running Win 7 have intermittent internet drops. One is older, one brand new fresh out of the box. Turned off the power saver NIC card function on both, WOL disabled. That's not the problem because the internet losses occur sometimes after the machine is on for a few minutes, the PC does not sit long enough to go into power saver anyway. There's no rhyme or reason as they say when the loss will occur. Sometimes this will not happen for a day or more, other times it can happen after using the machine for just a few minutes.One thing I have been trying is to disable IPV6 then I can get the internet back, othertimes re-enable it to get the net back. Go figure. Again, disabling it will not fix the problem, however switching it on/off will. Disabling and re-enabling the NIC will only fix it sometimes, most instances that does nothing. There are different types of NIC cards in the machines, one uses a Realtec on board, the other uses Nvidea on board and a plug in NIC (brand?) all NIC cards/board performs the same.Also, when they DO work, if I let them boot for a while, usually they will be fine, but that's looking at a 10-15 minute boot up. (doesn't take an excessive time for actual boot-up but I mean just leave it alone for 10-15 min) The Actiontec has the most current update version, and is about two years old. Somehow these machines lose the internet portion but not the network portion. Such an annoying problem, even more so when I added a brand new machine and get the same issues. I would be willing to bet that if I ran them wireless there would be no issue, but that's going to slow down the dl/ul speeds that I get with a wired connection.

In the old place my PC was upstairs but had an ethernet connection to the router downstairs.In the new place I have to run it on the wireless. I have got a 2/3 bar connection to the router, and can stream to the Xbox without a problem, for the most part.The problem occurs (and it's becoming more regular) when I turn both bits of kit on and the PC (in the media centre menu) says the Xbox is connected but the Xbox says no connection can be found.It then lists the normal helpful suggestions, and what I have to eventually do is unlink them and re build the connection.When that is back, it works fine, but turn them off and have to start all over again.

On these occasions, while watching Hulu on my HTPC, which only connects via WiFi on my Router (Cisco E3000), the movies were interrupted by a loss of connection, indicated by the white tray icon turning orange, and when expanding it's menu, the connection bearing the name of my network had disappeared.On the first failure, the flashing light on the network adapter (Belkin F5D8055) continued flashing as usual, but the steady light was out, until pressing the connection button. The second time around, both light remained lit as normal, but in both instances my network connection on the network adapter's tray icon had disappeared. Using the WiFi's network adapter's connection button, and the router's PBC button didn't solve the problem, nor anything else that I tried.Since the WiFI connection is primarily for internet access, rather than connecting computers, and that shutting off my desktop doesn't usually effect the HTPC's internet connection, it seems obvious that the connection is managed by just the router, adapter and HTPC, so I fail to understand the relationship between the vanishing network and the loss of internet connection.When these failures occurred, they only lasted for ~ 10-15 minutes, and then were restored on their own, with no more apparent reason than the outage had. So far, this is only an annoyance, but I fear that it is an omen of greater problems on the horizon, and I have no idea of how to isolate the origin of the problem..

I had my Windows 7 running for 3 days with no issue, perfectly i must add, but up from Tuesday I'am struggling with really critical network issue.
I'am really turning on this forums as last resort, and I'am closer and closer to roll back to WinXP (which i really don't want...). But let me begin describing the problem from the beginning.
Some hardware specifications:
Windows 7 x64 7600 Polish Version
Motherboard: Asus P5QL Pro (with Intel chipset)
Network adapter: Atheros AR8121/AR8113/AR8114 PCI-E (On Motherboard)
Connection: Wire, Ethernet, straight to Modem
Modem: WebStar EPX2203
Antivirus: None
Firewall: only default Windows firewall
- On Tuesday (24.11) morning (+1 gmt) I've installed drivers to my Network adapter which were in Windows Update.
- While playing Team Fortress 2, i started having really akward lag. I was able to hear and see everything around but i couldn't react. Then after couple of minutes my net got disconnected, loosing connection to the internet for a brief moment (up to 1 minute)
- I've blamed my internet supplier but the lag continued throughout whole day. Even during phone session on Skype it managed to last 5-30 min, finally ending with short net disconnection. Steam games weren't the only one affected, as while playing Borderlands i have also suffered from a lag, same type of lag like in TF2 (heard, and saw but couldn't do anything in-game)
- Until today, I've reinstalled (that is uninstalled adapter then installed, also in Safe Mode) drivers for my Network Adapter many times. Forcing Windows to not install his own, but only that which i chose, picking from all 3 drivers (from newest to oldest) which are supposed to be supported by Windows 7.
- I have also dabbled with Task Offload and unchecking IvP6, turning off Windows Firewall, but none of these brought any solution.
- Now I'am after fresh reinstallation of Windows 7, thinking that will resolve everything. But after i've installed every needed driver (for Graphic Card, Intel Chipset, HD Realtek Audio, updating DirectX, without updating Windows at all) and launched Team Fortress 2 to test out if lag is still present i've sadly encountered same as pre-reinstall of windows7.
Any ideas?

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 a Acer aspire 5536 laptop with ATI Radeon HD 3200 graphics card which i connect to my Pansonic TX-L37G20B LCD Tv via the HDMI output on a regular basis to watch films etc. I have had no problems with the connection since the day i bought the TV and have been happlily using it for the last 2 years.
A couple of days ago i connected the laptop to TV as usual and changed to the correct HDMI channel and got nothing. I disconnecetd the lead and reconnected but still no picture or sound on the TV. I tested the HDMI cable and Tv input by connecting the lead to my XBOX and it worked perfectly.
When i connect the lead to the laptop the screen goes blank for a second and i hear the connection sound as normal however no picture on the TV.
I have checked the display settings and the TV is listed under monitors. I have tried all settings eg extend display, duplicate etc.. and it appears to work correctly but i cannot get a picture or sound on the TV. I did think maybe this problem was due to a recent windows update so i have run a system restore to a previous time when this worked, but no joy. I have also unistalled the old graphics card drivers and installed the new ones from the AMD web site and again nothing.

My computer is relatively recent only being bought back around Feb/March. For the past month the machine has been crashing and when I log back in I need to restart my router in order to get my internet connection back. The strange thing is that other computers connected to the same router also lose their connection shortly after the BSOD on my machine (both machines have wired connections). I am using the same OEM copy of Win 7 Professional 64 bit that was installed when I bought the machine.I have tried updating the drivers on the network card but that does not seem to help. I also tried looked at the dumps with WinDbg to see if I could find a specific driver that was playing up. I also turned on the driver verification a couple of times to see if I could find a driver that was suspect -- that caused almost immediate crashes but I could not get to the bottom of what was causing it but it could make it happen by starting up Mumble.The BSODs have so far seemed to happen when I am playing a game, using something like Mumble, or watching a stream.

I had a power loss while running on battery (it still showed power left, but suddenly shut down anyway) and when I restart, it reports that the Windows is not activated and Window is not genuine and system might be a victim of "counterfeiting."
Is this a virus (I have MSE on continuously and about once a week scan with Malwarebytes)? I have run 'sfc /scannow' with filtered output ('findstr /c: "[SR]" c:.....logsCBSCBS.log" and it appears as usual.
How can I lose my Windows activation?

I have Asus eee PC since 2010 with Win 7 and never had any problem. I was working on my laptop without any problem. But for last couple of hours I am not able to connect to my wireless network. It doesn't show any network. It only shows the message "Not connected. No connections available". I have internet service through out the house. Wireless is also working on my IPod, IPad and IPhone. I have desktop connected with network wire and internet is working just fine. When I connect my EEE with network cable, everything is working as expected. Only wireless is not working.
I already tried the following:
1. Restarted my eee pc
2. Restarted wireless router (doing this before, would remove any problem but not this time)
3. Tried clicking Fn + F2 buttons
Also, few minutes back my machine was updated with automatic update of Win 7 SP1. Nothing is working.. I don't know what happened. It is so frustrating to see things stop working without any valid reason.

I have a M2N68+ with a AMD AM3 215 CPU, and had all sorts of issues with CTD, and BSOD's, been pulling my hair out, finally got disgusted and pulled the RAM out and checked the QVL list and it wasn't on there, as a word of warning, if you are having problems with the stability of the system, check the QVL list and see if you have the same problem. BTW my Gigabyte board runs rock solid no matter what memory I use, this is the last ASUS MB I'll be getting for a long time.

I recently bought a Dell Inspiron 17R (N7110) that was on sale at Costco. It arrived on Thursday, October 13. However, from the beginning it doesn't always start up correctly. About 4 times out of 12 it got up to the "Starting Windows..." screen, but the 4 lights don't come together to form the windows logo (that's the startup animation). Each time I did a hard reset, and then it would ask if I wanted to run Startup Repair.First time: I think this was before I even installed any of my own programs. Tried running Startup Repair... which failed to start up, and I reset again.
Second time: Immediately following the first, I decided to run Windows normally without Startup Repair, and it worked.Third time: I decided to try Startup Repair again. It went through this time, and when prompted to try a System Restore I did.Fourth time: ...apparently that didn't work, because it happened again. This one happened when I started it for the first time this morning, 10/16. I noticed that the Seagate Drive was attached when I started it this morning. I did another System Restore.Fifth time: 10/16. Pressed F8 and tried to start with Boot Logging. Not sure if ntbtlog.txt recorded the failure, or only the following time when I tried to boot in safe mode. (Safe Mode did work the one time I tried that)

I have a compaq presario v2000. For the most part, my laptop screen says nothing like 'windows is non genuine', but there are some times when it does. The funny thing is , when I go to start, right click 'computer', click properties and see the computer information screen, the bottom part of that screen eventually says windows is activated, and after that the 'windows is not genuine message on the desktop goes away to reappear at a later date, maybe two or three days later

I built my system about 2 years ago and I've done my research and ran the memtest and stress tests and they all passed. But, I still get BSODs and it seems very random, if I'm listening to music, playing games, or just surf the net I get a BSOD now and then. It happens once every month but in the past week it crashed multiple times so I'm at my wits end.

I'm rather new to Windows 7 but I've done my fair share of installing versions of XP and Vista to my machines and I've never run into this issue.
I have a Dell XPS M1330 computer with 3GB ram. I chose to install the 32 version of Windows 7 Pro from Vista Home. Everything, including Aero was confirmed would work when I ran the upgrade advisor. I did a clean installation after backing up all my files and loaded the most current drivers from the Dell website that were applicable to my serial number.
My problem is that when the OS is shut down or restarted PROPERLY, some drivers don't load properly and I'm stuck with a frozen home screen. I definatly know that my trackpad and video drivers aren't loading because the cursor will not move and the screen resorts to the lowest resolution possible.
However, if I do a hard re-boot by pressing and holding the power button, effectively triggering my safe-mode prompts, everything loads properly. It seems VERY strage to me that this would happen - I would expect it to either work or fail - not a combination of both!
I'm just curious if this is something anyone else has come accross - or if I should call Dell and make sure the drivers are current for 7 and try re-installing everything.

I'm experiencing intermittent monitor black outs which last for about 3 seconds before the monitor comes back to life. They occur randomly and I've got no idea what is causing them. It has only started happening since I switched to HDMI from DVI. I'm using an Nvidia video card and a BENQ monitor.

I wanted to hop on the SSD band wagon a few months ago so I grabbed a 64GB SSD down my local store.I'm pleased with the fast boot times and applications like Photoshop (which always used to take 10-15 seconds to open), which now open within a second.I have been having an annoying issue though since the purchase which has got me considering going back to my old drive. I have formatted and reinstalled windows and experienced the issue basically within the first few hours of the format, so i assume its the drive. Below are a few things I experience...
*I will be navigating directories and exploring files when all of a sudden the hour glass will appear and make me wait for 5-10 seconds before allowing me to resume doing what I was doing.
*This happens in all windows applications like firefox (while browsing webpages) or within photoshop while navigating in application menus.
*sometimes the application or windows menu will hang for a couple of seconds.. sometimes 30 seconds !
*I never experience any actual application crashes.. just 'hanging'
*If I ctrl+alt+del .. nothing happens UNTIL the computer decides it wants to 'wake up'.
*If I continue to do things while the computer is hanging, when it 'wakes up'.. it will 'fast forward' many of the actions I did while it was hanging (if that makes sense). It does this Intermittently.. sometimes I have a good hour.. sometimes it can be an issue for a few hours etc.

In Media Center when playing a DVD about every 5 minutes the video will hang for a second and then go into slow motion and then catch up with the audio.
Its terribly annoying. If you know the answer, please share.
I have a HP 7680n (core 2 duo/2GB ram) with a kworld ATSC tuner and a 256MB Asus (ATI) video card using HDMI out.

I have a Sony with win 7 64-bit and 4 gigs of ram. About a month ago I started to notice my computer running slower. When I checked windows task manager (performance) it was using 3.5 gigs of my memory. I restarted the computer and it went down to 1.5. I have on occasion had to restart twice to get the memory down. I have run virus checks and reg cleaner but it still occurs.

I fitted a new hard drive and re-installed the OS for this client. After a couple of weeks it started to blue screen. At first I thought their usb wireless adapter was at fault. I removed it and everything was ok for another week or so. Then the BSODs started again.
I have tested the RAM and HDD - both fine. I have used Eurosoft PC-Check to stress test the machine and it was fine. I used the same software to test the motherboard and it passed fine. I used Prime95 64 bit to torture test the machine and again it wouldn't crash. Also I have run mbam and superantispyware and the machine is spyware free. It also has the latest video drivers installed. Typically since I brought it back to the office it has behaved impeccably in every way

I have an ideapad Y530 that is currently experiencing audio issues.I recently upgraded from Vista to 7 Ultimate and ever since the audio only works about 1 and 10 times. I have found many posts on the net with similar issues but nothing exatly like mine. All speakers have been enabled, audio driver updated and every type of trouble shooting tried.Basically i start the computer, get the Lenovo boot-up jingle, then no sound. But every ten starts, or so, the sound works perfectly? The only other strange thing i notice is that if i plug in speakers and put the volume on FULL i can hear sound ever so faintly.Feels like some sort of conflict but i cannot find one. Its as if Windows 7 loads the driver sometimes and not others, but if so why is the sound faint when i plug in speakers? Should i open the laptop to search for physical damage between the motherboard and speaker connections?

In the last two weeks I have noted that my Windows 7 Ultimate 64 Bit machine will boot, looks good and when I log into a user account the Desktop shows, without gadgets or icons and just sits that way for seemingly ever. Can't break in and must power down. I log into Start Normally and it will boot correctly. This has occurred usually in my user account and once on a rapid restart on the Owner account. I have used chkdsk to see if it is a physical problem. Out of my league but this hasn't occurred for 2 years and just intermittently occurring.

I have just installed Windows 7 Home Premium on an HP Pavillion a1629.uk, and the second internal drive is sometimes not present on booting up. The failure rate is about one time in ten. Originally the machine had C: and D: drives with XP installed on C:. The original C: drive was discarded, and a clean installation of Windows 7 was made on on a new 500 GB disk. The original D: 500 GB drive (Seagate ST3500320AS) was left in place, but as stated is sometimes not detected. The drive is always present in the BIOS, before windows boots. On the occasions that it is not detected in Windows 7

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?
