hi

the T21 has PCMCIA slot , you need a WiFi card (PCMCIA) : i dont believe it has built in or isntalled WiFi card.

hi

the T42 does not have WiFi, instead it facilitates internet connection via 16 BIT & 32 Bit PCMCIA slot to install a WiFi card , in order to go on the internet.

The ThinkPad uses the following adapters: v 360, 365X, 380, 600: 16-Bit PCMCIA v T20, T22, T23: 32-Bit CardBus and MiniPCI v T23: 32-Bit CardBus and MiniPCI Daughter Card v T30: 32-Bit CardBus and LAN on Planar Board (LOB) v T4x: 32-Bit CardBus and LAN on Planar Board (LOB). 16- and 32-Bit PC Card adapters are configured during ThinkPad initialization. Network Interface Controller data rates are: v For Token Ring: 4/16 MBps v For Ethernet: 10 Mbps...........16 bit PCMCIA 10/100 Mbps.......32 bit CardBus 10/100 Mbps.......MiniPCI and Daughter Card 10/100 Mbps.......T3x and T40 LOB 10/100/1000 Mbps..T42 LOB The MiniPCI Ethernet adapter is accessed behind a removable plate located on the bottom of the ThinkPad directly above the Model/Type S/N sticker. For T20 and T22, the MiniPCI adapter may be an Ethernet/Modem combination card. The Daughter Card (T23) is secured with two screws and is located next to the MiniPCI modem adapter.

please rate my service

the r40 has no hardware switch. it has a software switch. you must first determine what type of wifi card if any is installed. most of the stock cards are intel or cisco and the ibm support site has the software used to control them. sometimes, thru the network connections, windows can take control if the drivers are installed

The wireless driver may got corrupted or uninstalled.
Go to Control Panel - System - Hardware - Device Manager - Click on Network Adapters and if the wireless card is listed click on it to see if it is working and enabled. If not then reinstall the wireless driver.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

if drivers installed device is looking for wifi manager which is the software package for wifi.
you can goto control panel open administrative tools select sevices and scroll to wireless zero config and press start.
this will then use windows settings.done

no it will not work.

Hi,

To my knowledge an IBM ThinkPad T21 originally was shipped out from the manufacturer without a WiFi networking interface, sorry.

Kind regards.
