I just installed Vista Business, tested it for 4 hours, same effekt.

30% of the Systemstarts i have to deactivate and reactivate the network connection manually.

And i had another effekt on both, XP and Vista.

When a iPod 5 Gen. is plugged in the Notebook wont start.

I think it´s time for a working Bios and a working Intel Matrix Driver.

What is the boot order in your BIOS?  Also, what are the USB settings configured for?

For the network problem, have you already tried (re)installing the latest driver?  Have you run the diagnostics?

sorry, misread the post.  how do you delete these things?

Hi!

I had the nearly the same problem, with XP and Windows7. When I unplugged the network cable and plugged it in again, it stayed with 'not connected'.

Even disabling the NIC didn't help. Only rebooting, which was a little bit annoying.

Finally I gave the driver directly from Intel a try and guess what? For the moment, it seems to be better.

Hopefully, that'll help.

I am having this same issue with xp vista and 7 what is the answer dell? We have 45 of these sitting waiting on a call or email from your tech dept befor we can release these.....

Yes - I would like to know the answer as well.  I have a relatively new Latitude e6400 with this issue.  It's been giving me fits for the last few weeks.  Now, if I plug in, everyone around me (on the same network segment, network switch, etc.) is dropped from the network.  That is, my network interface appears to have a physical problem that affects other network users.

This is a serious issue for me.  I can use the wireless as a backup.  It doesn't appear to be affected, but I don't have any hard evidence either way of anyone else being affected.  Unfortunately, I don't have wireless access everywhere.

I have 2 issues w/ the networking on the e6400

I'm having issues w/ the intel 82567LM  in XP.  The device has a yellow exclamation point next to it.
I cannot get it working.
When I tried to update the driver for it w/ the dell download the machine just froze up and had to be restarted.

Also, the Intel 5100 wireless card will not connect at "N" to a wireless router - I've tried both an Apple and Nortel access point.
I've seen other people having the same issues w/ this card regardless of whether it is installed in a Dell or HP.
When I disable the "N" mode, it connects perfectly.  However, now this functions as a "G" card.
Is there a fix for this?

Any ideas?

Thanks

Hi,

with my new E6400 (windows 7 professional) I had similar problem: lan was dead ("no connection / no cable") after wake up from standby or hibernation and sometimes even after a reboot. No problems with WLAN, but I want to use the wired connection whenever possible. Deactivation and reactivation of the lan adapter and removing and inserting the cable usually reestablished the connection. Doable, but annoying. New drivers from the Dell website or fiddeling with IP adresses / DHCP didn't improve matters. Then I noticed the status LEDs on my DSL router & switch, which happens to sit next to my desk (it supports fast ethernet but not  Gigabit: They were off in the problem state and only started blinking with a successful reactivation of the adapter. . Not really a networking expert I went through the settings of the adapter and found the speed setting. The adapter was set to automatic negotiation. After setting it to 100Mbit/s Full Duplex everything was FINE, no problems whatsoever for days now (relief!). My hypothesis: After wakeup of the laptop one or both of the partners expected negotioations about connection parameters, which however didn't happen.  Is there somebody knowledgeable in the forum who could comment on that? Anyway, for me the problem is solved.

Greetings, H.

Have you identified this problem yet, I'm seeing this issue on two diffrent E6400's with XP SP3 installed as well. I'm going to try a BIOS upgrade to see if this works. I hope it's not a Nvidia chipset issue.
