I get the same issue with Nightwolf after installing the driver. A ! appears on the network adapter seen in the device manager. In the driver's release notes, it only claims to support PRO/1000. I think there's something different between PRO/1000 and PRO/1000 PL.

No. After rebooting we need ping again.

I find a solution. Just ping t60 from other machine. :) After ONLY 10 to 20 minutes (sending about 1000 icmp packages), the latency will be normal and stable. See below: [wf@WFPC wf]$ ping 202.197.20.52 ... 64 bytes from 202.197.20.52: icmp_seq=1150 ttl=64 time=175 ms 64 bytes from 202.197.20.52: ic...

Theres a problem in the Intel microcode on these chips - a fix will be released soon i think so keep an eye on the driver matrix. Good news. Thank you, snife. Hope this is not a long term. And the seller said to me that another t60 has the same issue. But there's one thing I was confused, don't the...

You can disable the "Deep Smart Power Down (DSPD)" function in network adapter properties.I have fixed this problem by this.

Hi, Kai

I reinstalled my network driver and found this property (深度智能关闭电源), and disabled it. But it does not work on my t60.

I had a similar issue with a gigabit ethernet card connected to a gigabit port on a cisco switch. I solved that problem by enable flowcontrol on the switch port. Before i enabled flow control it was really slow to copy files to and from that PC. If you don't have a switch with management or without...

Hi Feng I and a few others have this problem too. I've got it on my X60s. It seems to have nothing to do with network cables, switches, firewalls or the like. See if these links describe your problem: http://forum.thinkpads.com/viewtopic.php?t=25307 http://www.hack.org/mc/freebsd-x60.html [snip] Ra...

Feng, another thing you could try is taking the network out of the loop and get another laptop sit it right next to the t60, connect with a short ethernet cable set up the tcp/ip for both and ping it that way, the only conclusion I could come to after that would be something wrong with the network ...

If you are on a switch, why does your TP have an outside address. If you are internal to a connection to the outside world via a switch, perhaps there is a TCP/IP or duplicate DHCP issue. ... JD Hurst The switch does not connect to the Internet. We construct a LAN in the same subnet. IP Address: 20...

Try pinging your own IP and also try 127.0.0.1, and what are the times if you ping your default gateway and your server IP address. If you suspect it is your network adapter run PC doctor. Make sure your cable is good or even switch it just to make sure and check the wall jack you are plugging into...

Thanks, claudeo.

No. Even I closed the Windows XP's firewall.

Hi, all The ethernet network adapter in my t60 is Intel PRO/1000 PL. Version of driver is 9.3.39.0 (Installed form Software Installer). We use a 100M switch to connect other computers. Normally the ping time is below 1ms. But if another computer ping my t60, the time is over 10ms, even hundreds of m...
