I found out that I have a hidden network device: Nortel IPSECSHM Adapter I don't even know how that got there. I tried uninstalling it, but I get an error: Failed to uninstall the device. The device may be required to boot up the computer. Both my wired and wireless connections have the Eacfilt driver, which I was able to trace to the Nortel IPSECSHM Adapter, I think. I unchecked the Eacfilt driver on both, but still can't remove in device manager. I'm not sure if this is what's causing the problem.

I turned off all AV & firewall and I was still having the same problem. I noticed the problem when I shared a directory for my colleague to copy some 2gb VM files. He was pulling it from the share. I thought he was causing the problem, so I tried pushing it. Same problem. I tried a cross over cable to his laptop (same model), same problem. I was the only one getting disconnected. I tried FTP to another workstation, same problem.

the firmware of the actual bios you mean? probably not. why would it start having problems all of a sudden? it's definitely not the switch. I tried a cross over cable from my laptop to my colleague (same model laptop) and only mine stopped working. I cannot reproduce except when I try to force copying large files, sometimes it stops. I've disabled the power management on the wireless and the wired. disabling and enabling doesn't work either. last time it happened, wireless status says I was connected, but I cannot ping my access point. I had to reboot.

I have a Lenovo T60 with an intel Pro 1000 & Intel Wireless 3945a. Lately, I noticed I get diconnected from the network. The only thing I can ping is myself even though the network cable is connected. When I try to renew the ip address, it doesn't renew. Basically, my only way to get connected back is to reboot my laptop. I noticed that if I copy large files (2gb files, vm disks) on the network, it will lose my network connection and need to reboot. I did an virus scan using symantec enterprise 10.2 and it didn't find anything. I also tried avast. nothing. I get errors like: The system detected that network adapter \DEVICE\TCPIP_{02193CA1-BB30-4F2F-B7DE-373819E6E2D0} was disconnected from the network, and the adapter's network configuration has been released. If the network adapter was not disconnected, this may indicate that it has malfunctioned. Please contact your vendor for updated drivers. I've tried updating the latest drivers for my network card. Nothing. So I'm not sure what I've got, and why I lose the network connection. Only this particular laptop. No one else is having the problem. I'm a techie, so this one stomps me!
