T450s Network adapter stops working

We've got a number of T450s laptops which we have imaged with Windows 7 Enterprise x64 using SCCM 2012. Although it took a bit of work to get the laptops imaged with the I218-LM network adapter, we were eventually able to get this driver loaded under WinPE and the laptops imaged successfully.
We are attempting to use Windows Easy Transfer (aka WET) to transfer profile and config info from older laptops (T410 / T420) ... During the transfer, the network adapter will stop passing all TCP/IP traffic. The WET transfer stops and even simple pings fail. Disabling and re-enabling the I218-LM network adapter causes network connectivity to restore and the WET transfer to continue, though it often fails again in a very short time-span (10-60 seconds). This stoppage of TCP/IP traffic happens apparently at random, but I"m sure there's some pattern we haven't ID'd yet. There does appear to be a high corrilation on the traffic stopping during heavy activity during the WET transfer.
When the IP traffic stops, the NIC's packets sent/recieved counters do not increment. Outward signs still make it appear the NIC is connected (link state shows up, LED incicators on the NIC still are lit with the orange indicator flashing).
We have tried two different drivers from Lenovo: 12.12.80.19 and 12.12.80.1950
I've also tried downloading drivers direct from Intel, package version 20.0, which installs driver version 12.12.80.19
I've already also tried disabling many of the harfware acceleration features (RSS, IPv4 TCP/UDP offloading, etc)
Has anyone else run into a similar situation or have any clue how I can stop the network from stopping?

Unfortunately I still don't have a resolution to this... But I wanted to add a piece of information...
I was able to replicate this problem using Lenovo's stock (OEM) install of Windows. This should effectively eliminate the posibility that we introduced the problem with our custom load.

Windows 7 x64 Network Adapter Stops working on high load

My Network has been failing and it has been happening for about a month or so on Windows 7 x64. I dont think that the system configuration is the problem as it is happening on 2 seperate machines. One being a relatively beefed up "white" box, 4 gig OCZ ram, EVGA nForce 790I SLI Mobo, Q9600 Quad core processor, dual raid 1 - 150 Gig Raptors, 2 8800GTX SLI cards, Pure Power 800W PS. The second machine is an IBM Netbook S10. I use the Netbook as a media center connected to a Pioneer Elite 1050HD. One thing is I have a PS3 and have several 1TB Esata drives connected to an IOGear 3132 Esata 3.0Gb pciX card to my desktop.
My typical usages:
1. FTP from a private server
2. Streaming music via Winamp
3. Streaming video 720, 1080 from pc to PS3 via the PS3 Media Server
4. DLing demos or movies on the PS3
5. Network streaming a movie from the Esata drives to the bedroom or kids rooms
6. Streaming video from abc.com or southparkstudios.com from the Cox cable modem
7. RDC over VPN to work machines
Now I have noticed that when I am streaming HEAVILY, from any 2 of the above mentioned, my network connections will simply stop working with a yellow exclamation mark on the task bar network icon after a few moments, nothing in the event logs, no logs or ANYTHING at all. It will simply stop working no notifications or anything poof, gone. I have EVERY single patch, driver anything I can think of installed. Nothing works, the timing is completely random. FYI I have a NETGEAR ProSafe VPN Firewall FVX538 with a cable modem connection on WAN 1 and a cellular connection on WAN2, these have no impact I feel on the connections because the PC may go down or the Netbook will go down depending on which one has the most load. So this simply tells me that it it not a firewall router problem as I have tried using a cisco unmanaged 24 port 1GB switch and I get the same problems. From analyzing the systems and layout I am led to believe that it is either a network adapter driver OR a Windows 7 problem (collisions, unhandled exception?), this NEVER happened with XP or Vista. I have tried everything but a new network adapter, I have tried the secondary adapter card on the mobo, I have tried bridging the two, I have tried daisy chaining the switch and putting each machine on its own dedicated switch linked to each other with no change. When the network goes down it is only that box effected, all other machines still connect to each other fine, only the one with load shuts down and the only ones that shut down are Windows 7. These machines are all wired with commercial cat5e patch cables, they have all been swapped for new ones lately. All networking and PC equipment are on UPS so I doubt voltage variations. Windows Firewall is disabled I only use the hardware firewall, I do not use any antivirus.
I am completely out of options, can anyone recommend a new route?
In addition when I go to the command prompt and attempt to do an ipconfig /release. I get an error saying that the adapter is not in a usable state. Very irritating, this forces me to reboot, or right click disable/enable on the network adapter. The right click route takes almost a minute to complete.
Tried update driver in nvidia control panel, no luck. I have also turned off the networking power saver option in the adapter settings.

Hi,
Considering this issue occurs on 2 different machines, I also think this issue may be more hardware related. You may also try the following:
1.    If the computers are connecting to a router, please ensure the router’s firmware is up-to-date.
2.    Please run the following command in an elevated command prompt in Windows 7:
netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
netsh int ip set global taskoffload=disabled
3.    Disable SNP in Windows 7 by setting Registry as following:
Note: Please perform a full-system backup first.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
EnableTCPChimney=dword:00000000
EnableTCPA=dword:00000000
EnableRSS=dword:00000000
If the keys do not exist, please create them and assign the value.
An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers
4.    If the issue persists, please add another network adapter to this computer and see how it works.
Hope this helps. Thanks.

Hi, I'm experiencing a simular problem here.
My PC was using Asus P5Q-E motherboard but exchanged it for Asus P5Q TURBO Pro because it loses 'connectivity ' after an interval between a few hrs to 26hrs. During this state, I can't browse or my Outlook to check emails. The only thing that can send/receive data is Vuze. Plus, the strange thing is that the network icon says there's nothing wrong at all (when it obviously there is). Even the currency desktop gadgets says the time elapsed since it 'lost connectivity '.
I initially thought P5Q-E was faulty so now I'm using the TURBO Pro. However, the problem still persisted.
I am using Win 7 Ultimate x64 with all the updates and drivers. Connected via LAN cable to the router and the firmware is the latest. My ISP sent me a replacement router to confirm that their equipment is not faulty, which is true.
I have tried the above methods 1-3.
Although I'm not sure if I implemented Method 3 correctly since I don't usually go to the registry but here's what it looks like after creating it:
EnableRSS   REG_DWORD   0x00000001 (1)
EnableTCPA REG_DWORD   0x00000001 (1)
EnableTCPChimey REG_DWORD   0x00000001 (1)
There are 3 more PC's and 1 laptop in the house. 2 PCs use Win XP, 1 uses Win 7 Ultimate x64 and laptop uses Linux Ubuntu.
My PC has a second OS, Linux Ubuntu, I used it to time trial both motherboards (before and after switching) and found no problems at all even after 48hrs, so it confirms it's not a hardware issue.
The other PC's apart from mine are connected wirelessly. As far as I've been told, they don't experience the same issue I have.
I've been trying to tackle this problem for months now and I'm frustrated to reboot my PC every time it 'loses connection '.
I chatted with Asus about the issue when I still had the P5Q-E mobo, they said that they built a simular system to mine with the same mobo and said they couldn't reproduce the problem I'm having. THey even tested on other mobos with the same LAN chip and found nothing wrong. That's why I got the TURBO Pro that has a different LAN chip.
Anyone got anymore suggestions???
Thanks in advance.

Pavilion G7 wireless adapter stopped working and now will no longer boot.

I bought a Pavilion G7 about 7 months ago.
After a couple of months, the wireless adapter stopped working, it just disappeared from the Device Manager (Win7 Home).
I reset the computer to factory settings and it fixed that problem.
One month after this, the wireless adapter problem returned, I tried to use system recovery to restore it to a previous point, no luck.
I closed the laptop after this, didn't turn it off.
Opened it up and decided to watch a video I had on there, I had to pause the video halfway through (used Windows media player). Came back to continue watching and the screen was black. No lightbar activity, just blackness.
I pressed a few buttons, nothing.
Decided to do a hard reset (hold the power button for 8 seconds) then I left it and turned it on again, the blank screen returned, no signs of life, no boot, no HDD activity, nothing. The caps lock button was on, the wireless light (of course) was orange.
What on Earth has gone wrong? What can I do to fix this?
Thanks.

SOA FTP Adapter stops working abruptly

Hi All,
I have a ftp service which provides XML file streams real-time on a remote machine. I connect to this FTP server using the SOA FTP adapter and process files by polling based on timestamp every 3 seconds.
The issues I face are
1) The ftp adapter stop working abruptly. Has anybody faced this issue, if yes how can this be resolved?
2) The XML files comes to FTP location at the rate 2 files per second. Ideally I want to procss this files real-time using FTP adapter. But the backlog build is causing issues. How do I fix it?
3) If there is any downtime in production how should the SOA FTP application be activated after restart.
Also, what are the other FTP adapter configuration required to optimize the SOA FTP application to meet my business purpose.

I am using SOA 11g Fusion Middleware. The error I am getting in the logs are as follows:

After i updated to mavericks, my usb ethernet adapter stopped working.

I'm not sure why, but when I updated my software to mavericks, my USB ethernet adapter stopped working.

I'm using that adapter:
http://www.edimax.com/en/support_detail.php?pd_id=445&pl1_id=5&pl2_id=26
After I updated to Mavericks, I installed the driver in this page, but it didn't work. Then I googled "AX88772" which is my adapter's part no. or something like that, and I installed that one:
http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=97
I wasn't expecting that work but that did work. So, I think the solution of the problem is finding the right driver. I hope you solve your problem too.

Qosmio X500: power adapter stopped working for no reason

Hi,
Now i have my Qosmio X500 for a year and i like it, however i have small problems with it, and i would like to know if it can be problematic.
The first thing is that my power adapter stopped working for no reason,
So i bought a new one, but it always made some noise when the laptop was fully charged.
I know people with the same laptop and their adapter didn't make that sizzling noise, it looks like it was already defect from the begin.
Then i have one dead pixel in the middle of my screen, no problem for me.
Finally my screen is a bit loose from the laptop, when i close it, i can move it, it always seems like it's not on it's correct place, because when i close it normally it's not 100% horizontal...
Also when i replace my screen, my speakers make crackling noises and my webcam stops working.
So all those problems i have annoy me, especially the last one (webcam and speakers problem), can this fit in the warranty of the laptop? I did extend the warranty for one year...
Thanks in advance.

> The first thing is that my power adapter stopped working for no reason,

I think this is AC adaptor fault maybe a broken cable or something like that I would recommend you to replace this get in contact with the dealer and ask for the new one.
> Then i have one dead pixel in the middle of my screen, no problem for me.
I found a info about such issues:
+Information on screen technology and pixel failure tolerance for LCD displays
+http://aps2.toshiba-tro.de/kb0/TSB9502LZ0000R02.htm
> Finally my screen is a bit loose from the laptop, when i close it, i can move it, it always seems like it's not on it's correct place, because when i close it normally it's not 100% horizontal...Also when i replace my screen, my speakers make crackling noises and my webcam stops working.
Maybe you should ask Toshiba notebook technicians for a check maybe some screws or the hinges are loose.
The speakers should be checked with connected headphones. If you will not notice the same crackling sound using headphones, then the issue might be related to speakers

Airport Express Wireless Network Suddenly Stops Working

Hi, I have a wireless network set up with a single airport express using WPA/WPA 2 Personal wireless security. The 5 daily clients on the network are 2 Mac laptops (Both Mac OS X.4), 2 PC's (1 Windows XP and 1 Windows Vista), and an iPhone.
Internet comes in from a Comcast connection directly into the airport express, which is set to create a wireless network and play music wirelessly using AirTunes. The Base station software is up to date, on Automatic Channel selection, and connecting to the internet using DHCP, automatic configuration and sharing a public IP address.
For some reason, every couple of weeks the airport network just stops working altogether. My Macbook Pro shows that it still has a connection with full signal to the network but has no internet connection. When I disconnect and try to reconnect, all attemps to reconnect fail. No other clients are able to get internet at this point, and I cannot even access airport settings from my Macbook Pro unless I manually reset the airport by unplugging and plugging it back in. With this reset the network starts to work again immediately and continues for several weeks again. Does anyone have any idea why it would have this random shut-off every few weeks? Thanks

I have a similiar problem. Every now and then, connecting to my Airport Express network results in "there was an error joining the airport network". It appears to me that this happens at random. Usually, the problem is solved by rebooting to Windows XP using Boot Camp, connecting to the network and then rebooting to OS X.
Recently, it's become worse: the problem persist but sometimes even rebooting to Windows doesn't solve it anymore. When I try to find out what's going on using the Airport Utility, the program tells me "airport utility was unable to find any airport base stations". The only thing that helps in this case is resetting/unplugging my Airport Express and reconfiguring it.
The problems occur independently from the type of security I'm using. It's very annoying and disappointing, since my current high-end MBP has this problem and my previous mac (an iBook) never had it.

My 3rd party 30-pin adapter stopped working after iTunes update

Although I've been getting warning messages ever since my iPhone was updated to iOS7, I was still able to charge my phone with the 3rd party 30-pin to lightning adapter. But suddenly yesterday the adapter stopped working. the only thing I can think of was that I plugged in my iPhone 5 to iTunes to sync my music, and my PC updated my iTunes to v11.1.3.8. Can anybody offer any help as to how I can get my cable to work again?
Thanks,

That's because the adapter was produced illegally using stolen Apple patented technology. It does not have the proper authentication/DAC chip in it. Buy a legal 30-pin to lightning adapter.

LAN Adapter stopped working

My laptop’s local area connection adapter (LAN) suddenly stopped working. The laptop is an HP Pavilion dv6t-6c00 CTO Entertainment Notebook using windows 7 home premium 64-bit operating system. The network LAN adapter is Realtek PcIe GBE Family Controller. By the way, the wireless adapters include (a) Intel (R) centrino (R) wirless-N 1030 (b) Cisco AnyConnect secure mobility (c) Microsoft virtual WiFi miniport. Wireless works just fine, but LAN suddenly stopped working.
Concerning the LAN here is what I have tried: (1) The Ethernet cable works just fine for my other pc’s LAN and I switched Ethernet cables that also work for my other pc’s LAN. (2) Using cmd function for ipconfig/release and ipconfig/renew, I get the same messages as follows “… media disconnected…” (3) Using device manager I reviewed to make sure all the network adapters were working correctly and enabled. (4) Using device manager I uninstalled and reinstalled the network adapters. (5) I checked for updates for the network adapters and I’m using the most recent updates. (6) The diagnostic message I get when I test the LAN is, “an Ethernet cable is not connected or is broken” (7) I’ve rebooted the HP and router many times. (8) The router is fine, because wireless works on the HP Pavilion and the Ethernet cables work just fine on my other pc.
By the way, I don’t believe the Ethernet port is fried because there was no burn smell. I think it is the adapter since I get media disconnected message. Any suggestions or recommendations on how to fix the LAN?

@InfoSeach ,
Hello and thank you for posting on the HP support forums.
You have covered all the steps that normally are taken when diagnosing a LAN issue. Except one.
Did you check the pins in the socket on your notebook? Are they all straight? Are any missing?
If they are all in good shape the next thing is repair. The size and location of the chips for the LAN adapter generally will not give off a burn smell unless they go through an over heat. If one tiny relay or cap goes controlling voltage you wont get a smell.

Broadcom 802.11n Network Adapter not working on Windows 7 64bit

As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium. I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve. This however just cropped up after two months of successful use. Yesterday it started failing to connect to the internet, telling me that no wireless connections are available. I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360. I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared. When I reboot my laptop, all I get is a notification that no networks appear in range. If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time. I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that

Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
already connected to a wireless network on startup.
I.a. Disable Device sleep on disconnect
Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
well.
Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
2. Double-click on Network adapters.
3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
4. Click on the Advanced tab.
5. Select Device sleep on disconnect.
6. Set the Value to Disabled.
7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

USB Ethernet Adapter Stopped Working On Mac Mini Server Running 10.6.6

Is anybody out there successfully using the Apple USB Ethernet adapter on a Mac Mini Server running 10.6.6? They have stopped working for me.
The boot disk in the 2009 Mac Mini Server in my classroom failed and after Apple replaced the disk and I reinstalled SLS and ran Software Update to bring the machine up to 10.6.6 the USB Ethernet adapter that was the interface to the outside world no longer recognized when a cable was plugged in. The cable was good and worked just fine if plugged into another machine or the built-in interface. At first I thought that the USB Interface had failed but after trying two new ones (graciously exchanged by Apple) and finding that none of them worked I'm coming to the conclusion that perhaps the warning on the package that the USB Ethernet only works with the MacBook Air finally became true.

Only the specific build of Mac OS X that comes with a MacBook Air includes the kernel extension to run the Apple USB Ethernet adapter, however there are no hardware issues preventing it being used on other Mac models if you have a suitable driver.
Generic USB drivers can be downloaded for free from http://www.sustworks.com/site/newsusbethernet.html and this worked for me.

Network adapter not working Win 7 64 bit boot camp

I have a late 2013 MBP r 15-inch 1 week old
Installed Windows 7 through boot camp and loaded the windows drivers and everything works fine except the Internet, when troubleshooting Windows said there is a problem with the wireless network adapter.
When checking in the device manager, I have only 1 unknown device and it's a Intel HM87 LPC conttoller 8c4b, I've tried updating the drivers to that with no help, still unrecognized.
Help please!

Forgot to mention that the only listed network adapter is the Broadcom 802.11ac Network adapter and it says it working fine (no errors).
