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 Intel Pro Wireless 2100

• iprowifi2200, supporta i chip Intel Pro Wireless
  2200BG
  2225BG
  2915ABG

• iprowifi3945, supporta i chip Intel Pro Wireless 3945

• iprowifi4965, supporta i chip Intel Pro Wireless 4965

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

Connettersi a un network wireless

Besides of course unencrypted networks, Haiku has preliminary support for accessing wireless networks via WEP encryption keys. WEP is an early encryption method, although not the most secure.

You can list available networks, join and leave them with the command ifconfig from Terminal:

ifconfig [wifi_device_path] [list|join|leave] (key)

You can find your wifi_device_path in the Network preferences applet, or by executing ifconfig -a.

Below are a few examples of connecting to a wireless network named wifitopia. For these examples we are assuming your wifi network card is /dev/net/iprowifi3945/0.

Mostrare una lista dei network wireless:

ifconfig /dev/net/iprowifi3945/0 list

Joining unsecured wireless network:

ifconfig /dev/net/iprowifi3945/0 join wifitopia

Joining WEP secured wireless network: (ascii password)

ifconfig /dev/net/iprowifi3945/0 join wifitopia mypassword

Joining WEP secured wireless network: (64-bit hex password)

ifconfig /dev/net/iprowifi3945/0 join wifitopia 0x4010FABEEF

Leaving a wireless network:

ifconfig /dev/net/iprowifi3945/0 leave wifitopia

Connettersi automaticamente a un network wireless

To make your system connect to a given SSID at each boot automatically, you can specify your wireless networks and passwords in /boot/common/settings/network/wireless_networks with the following format:

network wifitopia {
   password mypassword
}

If you don't create this configuration file, the system will connect to the first unencrypted network it finds.

Note sul WEP

• 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 ifconfig)

WPA encryption

At the moment there is no WPA encryption available in Haiku, though there have been some efforts bringing it significantly closer.

install-wifi-firmwares.sh

Per installare il firmware per le schede ipw2100, Intel iprowifi2200/2225/2915, Broadcom 43xx & Marvell 88W8335, dovete far partire lo script

install-wifi-firmwares.sh

The Intel ipw2100 and iprowifi22xx 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.
