It does not have a Centrino label. The label says "Intel Inside pentium M". If I go to device maanger, I do not see a wireless card under network (only a Broadcom 570x). Where else can I look to confirm whether I have an integral wireless adapter in my D600?

correct

The D600 offers five wireless choices: Intel Pro 2100 (802.11b), Intel Pro 2200 (802.11b/g), Dell 1350 (802.11b), Dell 1450 (802.11a/b/g), or none. If the machine has a "Centrino" label, it includes one of the Intel wireless cards.

Removing the cover reveals an AIR-MPI350 wireless LAN module. Now, why don't I see it in Device Manager? And why, when my wireless G access point is in operation, don't I get any reaction from the laptop (an associate who has a similar laptop says that his indicates to him whenever he is near a wireless network point).

Sounds like a pretty conclusive "no" already. Since all four the wireless adapters for the D600 are mini-PCI, the definitive test would be to open up the cover and see if there's an adapter present, as shown in this section of the D600 Service Manual.

(Power needs to be off before opening the cover!)

Perhaps it's not enabled. Fn-F2 should enable it. Press the "Fn" key, hold it down, press "F2", then release both. Reboot and see if the card is found.

When I do this, I get a large icon of an antenna show up (to signify that it is turned on?). But there is no other indication anywhere that anything has changed. Nothing under network connections.

Hmmm...sounds like it was off when the system was first set up! What happens if you reboot after enabling the device? Is it then detected by XP, and the proper drivers installed?

Jim

I followed your instructions, Fn-F2 (saw "antenna" in lower right)and then rebooted but nothing changed. Could it be turned off in the bios?

Could it be turned off in the bios?

Yes it can be. I haven't been able to locate details of how to enable it. Press "F2" as the system is starting, and see if you can find the setting. Sorry I can't provide more detail!
