Network Connection Blockage / Loss / Lag
Nov 27, 2009
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?

I have an acer aspire 5738z laptop with windows 7. I hadan issue with the screen sent it off for repair and it has come back and the wireless Internet won't work. I've tried everything, the wireless will be either very poor and then turn off or just doesnt work at all. When I try and connect to talktalk my Internet provider it says, windows was unable to connect, it has mentioned the wireless adaptor

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 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 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.

This has been an issue since I upgraded to 7201. It isn't constant, and seems to be worse when I'm downloading large files, especially multiple files from one source (like an album in iTunes). It is fixed by release/renew (or just letting Diagnostics do that).
If I'm not using a lot of data (regular web browsing, working on a database online, etc), it seems perfectly fine. It is holding so far downloading one track at a time on iTunes, but if I do 2, it drops the connection.
I'm using the Home network config, router is working normally, and I can't recall this happening before 7201. I've reset the router, upgraded firmware, and it only happens on this PC. I've set WINS, tried all settings for TCP/IP 4 and 6, and using the other ethernet port on my motherboard.
More of an annoyance, really, but I can't figure it out and it is bugging the hell out of me.
EDIT: I can still get 1 mb/s on a single download, but trying 2, I get 600/400 for about 10-15 seconds until it disconnects.

I've got a Shuttle SK22G2B (AMD Socket AM2) XPC kit that I recently transitioned from the RC 7300 'Ultimate' Windows 7 edition to a paid Windows HP version. Installation was smooth and basic functionality seems to work fine.
However I now have a persistant loss of network connectivity mostly connected with large file UPLOADs, it has happened after long absenses where I don't really have a connecting event but more often than not it happens during a sync with my dropbox.com account or with my windows home server (on the network).
I try to let the Network and Sharing Center repair the connection but that fails, when I try to reboot it usually hangs during the shut down process and requires a reset to get it running again.
This did not happen over 3 months of heavy Windows 7 RC7300 use with EXACTLY the same hardware. When the XPC is showing no connectivity I have full internet and intranet access from my Win Home Server (wired) and netbook (wireless) on the same router.

-XPC is hooked in via ethernet, NOT wireless.

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?

Until recently I ran windows xp. I shared a built in wall Ethernet jack with another desktop. I used my router (Linksys Befsr41) as a switch by disabling dhcp and connecting the wall ethernet and the two computers to the Lan ports on the router. The other desktop until recently was also running windows xp, but was upgraded and is now an apple imac running os x lion. My internet briefly stopped working but I was able to reset my router and get my internet running again. I then needed to reformat my build and installed windows 7 ultimate 32 bit. I cant quite pinpoint my problem. If I connect straight to the wall ethernet jack i have internet access. However if i use my router as a switch to get internet for both my pc and the apple imac, I will not have internet access. Sometimes the internet does indeed come back on in this circumstance, only to get disconnected again shortly. I am not sure who to blame because the router worked fine when spliiting ethernet for xp machines, and I have internet access when running straight from the wall to my pc

(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'?

i am thinking it it might be because i have bridged my connection for my 360, but i have a red x on my network connection but i still have full internet. i already searched and did many steps...even the cmd one but no luck. so could it be from my wired 360 via bridge connection?

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..

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?

my router is brand spankin new, 802.11n. the modem has since been replaced... but for the life of me, i cannot get a decent download/upload speed.I Used to get 28-31mb download on speedtest.net. then later it dropped to 17-25, and i said, Ok, thats not bad, not great, but not bad. now im down to .81mb-1.2mb average if im lucky i pull 3 or 4.my upload speed has always been no higher than 1mb. i am not 100% sure why, im prety sure they do it so i dont run servers, but it still seems a little low IMHO.I dunno whats going on, i have a bit of network experience, but all software end, nothing hardware end in the way of routers etc?

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?

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?

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.
