<h1>Workshop: Bezdrôtová sieť</h1>
2012-11-16 01:36:54 +04:00
<p>Rozchodenie bezdrôtovej siete je nevyhnutné v dnešnej dobe neustáleho sieťového pripojenia. Pretože udržiavanie aktuálnej podpory rozličného a neustále sa meniaceho hardvéru a ovládačov je pre malý projekt celkom nemožné, Haiku sa pri implementácii sieťových ovládačov spolieha na vrstvu kompatibility <a href="http://www.freebsd.org">FreeBSD</a>.<br />
Tá nám zabezpečuje obrovské množstvo podporovaného hardvéru, hoci zrejme nie 100% všetkých, ktoré existujú. Pozrite si online <a href="https://www.haiku-os.org/guides/daily-tasks/wireless#hardware-notes">zoznam podporovaných modelov</a> alebo sa pozrite do <a href="http://www.freebsd.org/releases/9.0R/hardware.html#WLAN">Poznámok o hardvéri FreeBSD 9</a>.</p>
<div class="box-info">Momentálne sa očakáva, že budú fungovať iba zariadenia PCI, PCI-X, PCI-Express, Mini PCI a Mini PCI-Express.<br />
Zariadenia PCMCIA, CardBus, ExpressCard, USB a ISA ešte vyžadujú ďalšiu prácu, než budú funkčné.</div>

<a id="firmware" name="firmware">Ako rozchodiť podporovaný hardvér</a></h2>
<p>Hoci sme prvú prekážku všeobecne podporovaného hardvéru prekonali, niektoré bezdrôtové ovládače vyžadujú binárne moduly firmvéru, aby správne fungovali. Haiku nemôže distribuovať niektoré z týchto proprietárnych súborov firmvéru z licenčných dôvodov. Haiku však obsahuje jednoduchý skript, ktorý stiahne a nainštaluje všetky proprietárne súbory za vás. Vo všeobecnosti, ak plánujete používať bezdrôtovú sieť, odporúča sa spustiť tento skript, aby ste zabezpečili, že váš systém má všetok tento firmvér k dispozícii, keď ho budete potrebovať.</p>
<p>Otvorte Terminál a napíšte:</p>
<pre class="terminal">install-wifi-firmwares.sh</pre>
2012-11-16 01:36:54 +04:00
<p>Teraz si prečítajte licencie a prijmite ich, aby sa nainštalovali všetky dostupné súbory firmvéru.</p>
2012-11-16 01:36:54 +04:00
<p>Ak nemáte prístup k internetu, aby ste mohli stiahnuť tieto súbory s firmvérom v Haiku, existuje aj offline spôsob, pozri <a href="#tips">tipy</a> below.</p>

<a id="gui" name="gui">Ako sa pripojiť k bezdrôtovej sieti</a></h2>
<p>By default, Haiku will join the first unencrypted wireless network it finds after booting up. To connect to a specific network, you use the Desktop applet <a href="desktop-applets/networkstatus.html">NetworkStatus</a>.</p>
<p>Right-click on its icon in the Deskbar and choose the network's public name (which is the "SSID" it broadcasts) from the context menu.</p>
<img src="images/workshop-wlan-images/join-network.png" alt="join-network.png" />
<p>A window opens where you enter the type of authentication (probably WPA/WPA2, WEP is not a secure encryption anymore!) and the password for that wireless network. Click <span class="button">OK</span> to start the login process.<br /> Depending on your hardware and network configuration this may take a while. You'll be kept informed of the progress by notifications:</p>
<img src="images/workshop-wlan-images/join-status.gif" alt="join-network.gif" />
<p>Once it reads "Ready" and the NetworkStatus icon in the Deskbar shows a green round light, the connection is established. If the notifications end in "No link" and a yellow triangle, something went wrong, probably an incorrect password.</p>

<a id="commandline" name="commandline">Ako sa pripojiť z príkazového riadka</a></h2>
<p>If you prefer to use the command line or would like to use scripting or the <span class="path">~/config/boot/UserBootscript</span> to automate things to join a specific network on bootup, there's the command <tt>ifconfig</tt>.</p>
<p>Start a Terminal and enter the first line to scan for available wireless networks:</p>
<pre class="terminal">ifconfig /dev/net/iprowifi3945/0 scan
name address signal auth
haiku-top 01:d0:19:a6:88:42 30 WPA
ArcorInternet123 00:20:12:a4:29:e1 15 WPA</pre>
<p>The path to your wireless network adapter has to be adjusted, of course.<br />
The output shows the public name (SSID), MAC address, signal strength and authentication method of all found networks.</p>
<p>To join a network, use this line and insert the respective public name (SSID) and password:</p>
2012-11-16 01:36:54 +04:00
<pre class="terminal">ifconfig /dev/net/iprowifi3945/0 join {SSID} {heslo}</pre>
<p>Make sure the initial configuration of the wireless network adapter after booting up has finished, before issuing <tt>ifconfig</tt> commands or they might be ignored. Depending on your hardware and network configuration that may take a while. Watch those notifications...</p>

<ul><li><p>Here is how you get to install your firmware if you don't yet have a working internet connection under Haiku. You download the following files while in another operating system, boot Haiku, copy them to their respective location and invoke the <span class="cli">install-wifi-firmwares.sh</span> script.</p>
<ul>
<li><p>Copy these two to <span class="path">/boot/system/data/firmware/broadcom43xx/b43-fwcutter/</span>:<br />

</li>
</ul>
<p>When all those files are in their place, proceed as described above, i.e. open a Terminal and type:</p>
<pre class="terminal">install-wifi-firmwares.sh</pre>
<p>Review the licenses and accept them to install all of the now available firmware files.</p>
