Vista - Intermitent Wired LAN Conection on Dell Laptop

Quoted, i have same exact problem.



Working on a Dell laptop (no, it hasn't exploded, yet :-)
An Inspiron 1300 with built in LAN, Wireless USB, modem, etc. as usual.

It has an odd fault:

The LAN connection drops out and in constantly.

I get a message : "A network cable is unplugged"
followed by "LAN is now connected"
on a cycle of about 5 seconds.

The LAN socket has 2 LEDS which they flicker oddly on, then off (which seems clearly faulty.)

What I have tried :

* not allowing laptop to disable NIC to save power
* re-installing NIC drivers
* disabling and re-enabling the NIC
* disabling the modem (nearby)
* Windows updates
* power or battery
* using another NIC (USB to LAN)
* different cables
* wiggling the connection

None of this has fixed it. formating hasn't either.

I did get it to work correctly for a few hours (power disable of NIC seemed to be the culprit the first time) but the fault returned (when I took it back to the client - grrr..)

Now it just will not work right at all, no matter what I try.

Has anyone seen such a fault?
Any suggestions?

This is just so random becuase i have no more ideas, formating was my last resort and i figured with replacing the nic card it would be for surly fixed, but i still have the problem, Im connected with a WIRE connection on a school network (university) and ive had 3 roommates plug there computers into my ethernet cable, and they are just fine, no problems at all. Does anyone have any ideas at all that i havent tried yet?

bump

I started getting intermittent dropouts on wired connection too, Vista Ultimate 64x.

It seems to happen most during file transfers to network locations, either many small files total above 80Mb, or medum files (photos) above 250Mb, or large single files of ISO size. It stalls before completing and then all network activity starts dropping as you describe above.

I've tried all sorts of fixes, nothing works.

Latest thing I'm trying is disabling IPv6
