Saludos:

Intenta este tipo de solucion:

Ejecuta en tu terminal:

dmesg | grep -i iwl3945

Si te sale algo como esto:

iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.0
iwl3945: Copyright(c) 2003-2007 Intel Corporation
Detected Intel PRO/Wireless 3945BG Network Connection
iwl3945: Tunable channels: 13 802.11bg, 0 802.11a channels
wmaster0: Selected rate control algorithm ‘iwl-3945-rs’
iwl3945: Microcode SW error detected. Restarting 0x82000008.
iwl3945: Error Reply type 0x00000005 cmd REPLY_SCAN_CMD (0x80) seq 0x4418 ser 0x0000004B
iwl3945: Can’t stop Rx DMA.

Luego de esto pones en la terminal:

sudo su

Contraseña de root

echo alias wlan0 iwl3945>/etc/modprobe.d/iwl3945

echo options iwl3945 disable_hw_scan=1>>/etc/modprobe.d/iwl3945

modprobe -r iwl3945

Me dices si te funciono ahi la tarjeta inalambrica
