This means the link on the capture interface went down during capturing. answered 07 May '13, 13:01  SYN-bit ♦♦ So how to solve it?? (08 May '13, 01:40) Ashraf Does this happen every time? Do you have logging on your switch? Does it show link-up/link-down messages? Is your cable OK? Did you plug the cable in firmly? (08 May '13, 01:51) SYN-bit ♦♦ i don't have a logging on that switch the cable is ok and every thing else is ok (08 May '13, 07:30) Ashraf Be very careful with such statement, without logging on the switch you cannot be sure the lower layer did not go down, renegotiated, then came up again. Replace your cable.

Did you check the power setting options of the NIC driver? Some drivers allow to disable an interface if the computer goes into power save state. Something similar to this: Regards answered 08 May '13, 14:05  Kurt Knochner ♦ i did but nothing happened, and this time it is captured only 20MB it is about 10 min (09 May '13, 04:52) Ashraf Then either your NIC (or your switch) may be faulty/broken or some other software (e.g. Network Profile Changer) on your system disables the NIC for some reason.

(10 Jun '13, 12:03) Ashraf maybe. The system could be configured to switch off system components to prevent damage caused by over heating. However, then I would expect a longer disconnect than just a few seconds and some information in the system logs about that event. (11 Jun '13, 03:20) Kurt Knochner ♦ |
what exactly is suddenly? 1 second, 1 minute, 1 hour?
If this an onboard nic or some USB dongle or a PCCARD nic?
it is a NIC and the capture was running for two hours and it stopped . then when i start capture again it capture for short time about 10 min and it stopped again.
