®®® Posted September 12, 2004 Report Share Posted September 12, 2004 Issue: After a 'clean' installation of Windows XP with Service Pack 2 (rather than an installation of the Service Pack 2 upgrade for Windows XP), the built-in Toshiba (AGERE) Wireless LAN Mini PCI card will not detect Wi-Fi access points or other Wi-Fi devices, due to an IRQ conflict. I found a technically more precise description for the "IRQ conflict": Agere MiniPCI wireless LAN device has TI1410 CardBus controller and 16bit wireless LAN device on MiniPCI card. This registry key is effected to assign a same IRQ for TI1410 CardBus controller and 16bit wireless LAN device. Affected models & WLAN card: Agere MiniPCI Wireless LAN (802.11b/11MBit) installed in: Satellite 5005-S504 5005-S507 5005-S508 5105-S607 5105-S608 5105-S501 5105-S701 5105-S502 5105-S702 5105-S901 5205-S503 5205-S703 5205-S504 5205-S704 5205-S505 5205-S506 5205-S5151 5205-SP505 5205-S705 5205-S119 Solution: merge this reg file Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Pcmcia\Parameters] "IrqRouteToPciController"=dword:00000006 note: - For Windows XP ServicePack 1 (clean install) this registry entry is also needed and available at the Toshiba support site since 2001 - if you have Windows 2000 you need to set the value to 0, else the device will not resume when coming out of standby - There were 2 firmware updates available (v8.42 & v8.72) for that card, but not anymore. If anybody is interested i can upload them plus the latest driver (Service Release v02-2.3), which you need when you update the firmware. This fix just made my WiFi happen!! After 2 years, i clean and fresh installed XP with a slipstreamed SP2. :) The Toshiba Wireless LAN Mini PCI Card was not detecting my AP and seems not to function anymore, but remembering this small .reg file brought it back to life! :) TICardBusIrqRouting.reg Quote Link to comment Share on other sites More sharing options...
