Il Wifi in Haiku

Hardware che dovrebbe essere supportato

Tutti i driver wlan forniti da FreeBSD 8 dovrebbero funzionare. Qualunque scheda basata su PCMCIA, CardBus, ExpressCard, USB o ISA non funzionerà. Solo PCI, miniPCI, PCI-Express, miniPci-Express e PCI-X sono probabilmente funzionanti.
I driver disponibili includono:

• aironetwifi, supporta almeno
  La serie Cisco Aironet 350
  Aironet PCI4500
  Aironet PCI4800
  

• atheroswifi, supporta quasi tutti i chipset Atheros in commercio (ma non i chip AR9285)

• broadcom43xx, supporta i chipset
  BCM4301, BCM4306, BCM4307, BCM4309, BCM4311, BCM4312 e BCM4318

• iprowifi2100, supporta i chip 2100

• iprowifi2200, supporta
  2200BG
  2225BG
  2915ABG

• iprowifi3945, supporta i chip 3945

• iprowifi4965, supporta i chip 4965

• marvell88w8335, supporta
  Marvell Libertas 88W8310
  Marvell Libertas 88W8335

• marvell88w8363, supporta i chip 88W8363

• ralinkwifi, supporta
  RT2560
  RT2561S
  RT2561
  RT2661

• wavelanwifi, supporta almeno
  3Com Airconnect
  GLPRISM2 WaveLAN
  Intersil Prism3
  Intersil Prism2.5
  Linksys WDT11
  Netgear MA301
  PRISM2STA WaveLAN
  Siemens SpeedStream
  SMC 2602W
  Us Robotics 2415
  Addtron AWA-100 PCI

WEP encryption

WEP encryption is available through a command-line application setwep. It is a temporary means for joining an unencrypted or WEP encrypted wifi network. setwep works with 64- and 128-bit WEP and supports both text keys as well as hex digit keys (see WEP notes below).

The usage is: setwep device_path [ssid] [key]

Below are two examples. Let us assume your wifi network card is "/dev/net/iprowifi3945/0" and the wireless network is named "haikuwifi".

Example 1: Connect with 64-bit WEP encryption using a hex digit key

setwep /dev/net/iprowifi3945/0 haikuwifi 0x3456789abc

Example 2: Connect to an unencrypted wireless network

setwep /dev/net/iprowifi3945/0 haikuwifi

WEP notes

• 64-bit WEP uses a 40-bit key, which means 5 text characters or 10 hex digits
• 128-bit WEP uses a 104-bit key, which means 13 text characters or 26 hex digits
• hexadecimal digits = characters 0-9 and A through F (prepended with "0x" in setwep)

WPA encryption

At the moment there is no WPA encryption available in Haiku. However, there is some preliminary and unfinished code for implementing WPA available. Some tasks for improving this is to plug it into the wpa_supplicant build process and then fixing compile & runtime issues.

install-wifi-firmwares.sh

Per installare il firmware per le schede ipw2100, Intel ipw2200/2225/2915, Broadcom 43xx & Marvell 88W8335, dovete far partire lo script

install-wifi-firmwares.sh

The Intel ipw2100 and ipw22xx will install without an internet connection, as the licensing terms allow Haiku to distribute the original firmware archives. However, they do require acknowledgment by the end-user prior to their installation. The Broadcom 43xx and Marvell 88W8335 will require an active internet connection, as the files containing their respective firmwares cannot be distributed with Haiku.

People building their own Haiku image can modify their build/jam/UserBuildConfig accordingly. Details for that and general updates on the wifi topic are found at the online version of this document.

If you have to download the firmware, but don't have a working internet connection under Haiku, the online version offers a shell script, which will create a zip file for you to extract to Haiku's /boot. After that you'll have all files needed by install-wifi-firmwares.sh.
