Hi, my lan cable connection is disconnecting/reconnecting every few minutes. It's not internet problem since WiFi works fine. I've updated the drivers to latest, re-install from board cd, still the same. Also changed cable, same issue. It's very frustrating and i don't know what to do. What could be wrong? Please help.
My motherboard is MSI Z170A Krait Gaming R6 Siege.
I have Windows 10.
Thank you for the post. You may try installing the driver from our website to see if this will make any difference however we cannot guarantee the compatibility since you are using an OEM onboard NIC on MSI* system.
Have you also try connecting the I219 onboard NIC to another switch port to test the connection (if there is another port for connection)
Please contact MSI* for further support as they are in best position to check on the hardwarre aspect of the onboard NIC. Please refer to website below regarding where to contact for OEM onboard NIC.
I did but still same. Also contacted msi support, they told me to clear cmos, reinstall all drivers but it's still the same. I believe there's an issue with the adapter itself.
I'm getting this as well, just got a brand new PC. Tried old and new LAN drivers from both Intel's site and from gigabytes. Have tested my Ethernet connection to a laptop and it didn't disconnect once, so safe to say is not my ISP or my router or my Ethernet cable.
Windows 10 64bit
gtx 1070 8GB
Motherboard is Gigabyte GA-H170-D3HP
This is ridiculous.
I agree regarding the ridicule.
To add onto your experience, we are a medium sized organization with 500 users. None of our other desktops or laptops have experienced this issue. This issue started with the newest shipment of laptops we received a few months ago. We have been using HP laptops in the past without any issue until this new shipment that uses this model of on board network adapter. This issue is random and some laptops haven't failed yet while other laptops may go 2 weeks without a failure.
Considering this does not happen with any of the other model HP laptops, desktops or Lenovo laptops... we have come to the conclusion it must be the network adapter itself. the other model desktops and laptops we currently use that have no issue, do not use this model of onboard network adapter.
The network adapter model is the only difference we have found between the systems that work and the new laptops that exhibit this issue. Our model of NIC is a I219-LM indicating only a slight difference in implementation because they are integrated into mobile platforms which users lower power rather than a desktop.
This is causing us a huge upset in the department because we ordered and received a bulk order of laptops that have this model network adapter and we cannot use them. The few users we deployed these new laptops using this network adapter to are experiencing this problem. We stopped issuing them until we can figure it out and we currently have about 10 users who can only use our wireless network because of this issue.
We are beyond frustrated and Intel seems to be unresponsive. We will likely be contacting our HP representative and ask about returning over a few hundred laptops for a model that does not have this particular onboard network adapter in it.
Hope it all works out for you.
On another note If the on board I129-V adapter is fundamentally flawed in terms of bad drivers or design flaw...
Would installing a PCI Ethernet adapter to bypass the on board adapter work?
I'm glad you mentioned that.
Since these are laptops we couldn't use a PCI card, but we did install an external USB 3.0 Network Adapter and had no problem at all.
We've actually been able to connect an external USB 3.0 adapter while the on-board adapter was cycling between up and down states, and the external adapter worked perfectly with no problems.
CAn you help shared additional info below:
1. Brand and model of the switch or router
2. Try to turn off tcp offloading and power saving features such as allow the computer to turn off this device to save power in advanced properties of network adapter
3. SSU logs (Download the SSU tool at https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility) run the tool to generate the log then send to me
Thank you for sharing the information. The TCP offload can be adjusted by going to the advance property of the network adapter. Go to device manager-> network adapter-> locate your network adapter model-> Do a right click then click on Property
Go to the Advance tab-> You will find the TCP offloading option.
Hope this helps.
Have you tried the TCP offload option? And what is the brand and model of the external USB adapter that works without issue? Please feel free to share the test result.
Good day. As mentioned you are connecting to a wireless router, have you tried connecting to a non-wireless router to test? You can also try set the channels of your wireless router to
non-overlapping channels which can help improve the connection speed
Since i cannot use cable lan, i'm using usb tethering of my samsung phone to my desktop computer. Hence the usb adapter you see.
I tried the tcp offloading, no change. I've tried everything, it still disconnect/reconnect. I have this issue only with this computer.
I'm tired of this now. I'll simply buy a new network card.
Thank you for taking the time to test. I thought you are connecting to a Huawei HG8245H router, if you have the chance you may try to change the channel of your wireless router to
non-overlapping channels to isolate the issue. thank you for your time on this matter.
We have the same problem as "orionsume". Only in our case it is only 7 notebooks with the same behavior (2 Win 10 and 5 Win 7), which we got in May 2016 as a replacement for the 450G3 due to problems with Intel Graphics adapter driver. This matter was resolved a few days later…
We contacted HP. They first replaced the motherboard on one of the notebooks for toubleshooting reasons. All drivers were updated once more but no change. We even downloaded a driver issued by Intel in May.
Next, HP suggested a clean installation from the media (not system restore) and the application of the latest drivers from their site and only "important" updates from Microsoft. This seemed to resolve the issue. After testing for a couple of days, we continued installing other updates and software. When installing F-Secure Client Security the problem reappeared. Uninstalling it the problem disappeared (in the initial installation this did not work). Doing a lot of tests we concluded that the problem was caused by the firewall module of FSCS. So mid-July we opened a ticket with F-Secure (still troubleshooting). We installed FSCS without the firewall and network worked fine until last week, when it reappeared on the CFO's machine.
We performed a clean installation once again, only this time did not install FSCS. We used F-Secure's SAFE, provided for free from F-Secure until the matter with FSCS has been resolved. The problem appears again. Next we installed Panda Internet Security. Network disconnections again. Next we tried Kaspersky. Works fine. But next we installed Checkpoint VPN client and back to the beginning. Read in forums that Kaspesky in incompatible with Checkpoint. Installed McAffe. Works fine until installing Checkpoint Endpoint vpn. Uninstalled Checkpoint and reinstalled in basic vpn mode (secure remote) and finally works since yesterday. I do not know how long this will last.
Still this is not a solution for us. We never had such problems in the past and after all we need to use F-Secure since. McAfee and Kaspersky are only trial version for troubleshooting.
