Intersil ISL3877, ISL3880, ISL3886, ISL3887, ISL3890 devices (Prism54)

This page describes how to enable support for WiFi devices based on Prism54 chipsets on Debian systems.

Drivers

p54 is a driver supporting Intersil/Conexant Prism54 802.11g wireless LAN chipsets, introduced in the Linux kernel at version 2.6.24.

The produced kernel modules are:

• p54pci (supported devices)

  • Supports PCI, Mini PCI and CardBus devices with an ISL3877, ISL3880, ISL3886 or ISL3890 chipset.

• p54usb (supported devices)

  • Supports USB first (ISL3886 chipset) and second (ISL3887 chipset) generation devices.

p54pci and p54usb require non-free firmware, which must be installed prior to device operation. Device firmware is not packaged (481234).

The obsolete prism54 driver (supporting PCI devices with an ISL3877, ISL3880 or ISL3890 chipset) is disabled in Debian Linux 2.6.24 and later kernel images.¹

Prism 2/2.5/3 802.11b devices are supported by the hostap, orinoco and linux-wlan-ng drivers.

p54pci

p54pci is included as a module in Debian Linux kernel images. A specific firmware file - depending on your kernel version - is required to be installed.

1. Install the wireless-tools package:

   aptitude update && aptitude install wireless-tools

2. Acquire and install the relevant firmware:

   Linux 2.6.29 and later (Squeeze, Wheezy):

   mkdir /usr/local/lib/firmware
   wget -O /usr/local/lib/firmware/isl3886pci http://daemonizer.de/prism54/prism54-fw/fw-softmac/2.13.25.0.arm

   Linux 2.6.26 (Lenny):

   mkdir /usr/local/lib/firmware
   wget -O /usr/local/lib/firmware/isl3886 http://daemonizer.de/prism54/prism54-fw/fw-softmac/2.7.0.0.arm

3. As the p54pci module is automatically loaded for supported devices, reinsert this module to access installed firmware:

   modprobe -r p54pci ; modprobe p54pci

4. Verify your device has an available interface:

   iwconfig

5. Configure your wireless interface as appropriate.

p54usb

p54usb is included as a module in Debian Linux kernel images. A specific firmware file - depending on your kernel version - is required to be installed.

First generation USB devices (ISL3886 with net2280 bridge)

1. Install the wireless-tools package:

   aptitude update && aptitude install wireless-tools

2. Acquire and install the relevant firmware:

   Linux 2.6.29 and later (Squeeze, Wheezy):

   mkdir /usr/local/lib/firmware
   wget -O /usr/local/lib/firmware/isl3886usb http://daemonizer.de/prism54/prism54-fw/fw-usb/2.13.1.0.lm86.arm

   Linux 2.6.26 (Lenny):

   mkdir /usr/local/lib/firmware
   wget -O /usr/local/lib/firmware/isl3890usb http://jbnote.free.fr/prism54usb/data/firmwares/p54u_2.5.6.0.arm

3. As the p54usb module is automatically loaded for supported devices, reinsert this module to access installed firmware:

   modprobe -r p54usb ; modprobe p54usb

4. Verify your device has an available interface:

   iwconfig

5. Configure your wireless interface as appropriate.

Second generation USB devices (ISL3887)

1. Install the wireless-tools package:

   aptitude update && aptitude install wireless-tools

2. Acquire and install the relevant firmware:

   Linux 2.6.29 and later (Squeeze, Wheezy):

   mkdir /usr/local/lib/firmware
   wget -O /usr/local/lib/firmware/isl3887usb http://daemonizer.de/prism54/prism54-fw/fw-usb/2.13.25.0.lm87.arm

   Linux 2.6.26 (Lenny):

   mkdir /usr/local/lib/firmware
   wget -O /usr/local/lib/firmware/isl3887usb_bare http://daemonizer.de/prism54/prism54-fw/fw-usb/2.5.8.0.arm

3. As the p54usb module is automatically loaded for supported devices, reinsert this module to access installed firmware:

   modprobe -r p54usb ; modprobe p54usb

4. Verify your device has an available interface:

   iwconfig

5. Configure your wireless interface as appropriate.

Troubleshooting

• To enable use of channels 12 and 13 on Squeeze:

  echo options cfg80211 ieee80211_regdom=EU >> /etc/modprobe.d/local.conf

  Then reinsert the relevant kernel module (e.g. modprobe -r p54pci ; modprobe p54pci). See "Old regulatory implementation: The ieee80211_regdom module parameter" for more information.
