Intel 82567LM won't connect on battery...

My E4300 (in sig) has the above NIC, but whenever I boot up my laptop (from standby, hibernate, or even from shut down), it won't connect to the internet unless I disable the device and re-enable it. The NIC recognizes that a cord is plugged in and that there is a connection, but it just won't initialize it and connect to the internet. I only get "Local Access" until I reset the device, as I said earlier. This seems to only happen when on battery power.

I have the latest Dell driver for the device, and I've tried tweaking many power settings, but it just won't connect on battery unless I reset the device.

Any help would be appreciated!!

Thanks.

 

One of the power saving options in Dell ControlPoint is to put the network card on low power. On my E6400 this seems to put the speed down to 10Mb/s. Perhaps your network hardware doesn't like this slow speed.

Thanks for the tip John, but I've already tested it with this option both on and off. No bones.

 

Has anyone else with the Latitude E-series experienced this?

 

1. It will be worthwhile checking out the BIOS options. I don't recall seeing anything relevant on my E6400 but I once had a Fujitsu notebook which, by default, disabled the network when starting on battery unless one first plugged the cable in.

2. However, your problem is probably more local. Did you try right-clicking on the network adaptor icon and select repair? (Alternatively run a DOS box and type "ipconfig /renew"). This should try to get the network adaptor to request a new IP address from the router. How many people connect to the network?

1) Will check the BIOS settings on next reboot. Thanks for the tip!

2) I'm on my University's network. The number of people connecting would be measured in thousands. Also, when I try to do the repair, it returns, "There is still a problem, etc" which leads to the device reset.

Although last night, I plugged the cable in, and THEN turned the computer on, and it worked as normal.
