Wireless Network Adapters

This document covers IBM integrated (MiniPCI), Cardbus and PC Card (PCMCIA) Wi-Fi devices.

Finding out which adapter you have

For MiniPCI or Cardbus adapters run the command:

 lspci -n

And compare the PCI IDS with the once below.

Unsupported MiniPCI adapter

Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with a 'supported' adapter installed. Attempts to install an unsupported card will result in the following message:

  1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

The reason for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Committee).
