BEFW11S4- EtherFast? Wireless AP + Cable/DSL Router w/4-Port Switch. I really really like this WAP (Wireless Access Point). It is OS independent (read, linux friendly) and is configured using a browser so no need to touch Microsoft software at all, even to configure it. And if you don't know what a switch is, let me tell ya, they rock. Essentially they allow the NIC to communicate in both directions at the same time. I highly recommend one.

<para>You will also need some way to setup you IP address on your wireless card, I recommend either <screen>apt-get install DHCP-client</screen> to install the DHCP-client that will automatically configure your IP address, if you have a DHCP server. The WAP-11 hardware does provide DHCP server capabilities</para>
|
||||
|
||||
<para>Or at least have the <emphasis>pump</emphasis> application, which also will query a DHCP server and get you an IP address from the DHCP server. Note I tend to use <emphasis>pump</emphasis> when I am trying out new hardware to see if there is a connection, since to test a particular device, say <emphasis>eth0</emphasis> I would type <screen>pump -i eth0</screen> where the option <emphasis>-i</emphasis> tells <emphasis>pump</emphasis> what device to try to get an IP address. In this particular case, when I could not get Debian to automatically set up my wireless card, which was device <emphasis>wlan0</emphasis>, I would type <screen>pump -i wlan0</screen> and <emphasis>pump</emphasis> would try to set up the device. Anyway, the point is, that it is a good trouble shooting command, and you should know about it, and I talk more about it later.</para>
|
||||
|
||||
<para>I also recommend you use the "kernel-package" package when you want to build your new kernel, which I will get to. This tool is very good and you should be using it anyway when you are building new kernel for the Debian distribution. You can install it by typing <screen>apt-get install kernel-package</screen> Also, be sure to read the documentation it comes with, in case I don't do a good job explaining how to use it, later in this document

<para>One of the main stumbling blocks was to realize that the <emphasis>pcmcia support in the kernel is not as good as the pcmcia-source support</emphasis> that one gets when you build it from pcmcia-source.
|

</para>
|

|

<para>I use either <screen>make xconfig</screen> or <screen>make menuconfig</screen> to configure my kernel, so when you configure your kernel, be sure to not have pcmcia support enabled under <screen>General setup</screen>
|

</para>
|
||||
|
||||
<para>Nor do you want to select any particular pcmcia card under <screen>Network device support</screen>. I repeat you do not want this under the kernel and you will be building it when you download pcmcia-source.</para> <caution><para>Be sure to download all the necessary components before you take pcmcia support out of the kernel, otherwise, if you were using a pcmcia card for net access, you will not be able to connect to the Internet using the new kernel, until you have built both pcmcia support and module drivers for the wireless card</para></caution>

<caution><para>Don't Do this Yet!</para></caution>

<para>We need to get the pcmcia-source ready to be built at the same time as the kernel is built. This is a very neat feature of make-kpkg!</para>

|
||||
|
||||
<para>You now need to gunzip the file by <screen>gunzip pcmcia-source.tar.gz</screen> and then untar the file by <screen>tar xvf pcmcia-source.tar</screen></para>

<para>You should see pcmcia-source unpacked into the directory <screen>/usr/src/modules/pcmcia-cs</screen></para>

<para>Be sure the pcmcia-source is under /usr/src/modules.</para>
|
||||
<para>Go ahead and configure your kernel and be sure that pcmcia support IS NOT compiled in as an option in the kernel.</para>
|
||||
<para>To build the kernel and pcmcia-source, be sure you are under the <screen>/usr/src/linux</screen> or have a symbolic link from /usr/src/linux to whatever kernel source you have set up. Then type <screen>make-kpkg --revision=custom.1.0 kernel_image modules_image</screen></para>
|
||||
|
||||
<para>The <emphasis>kernel_image</emphasis> option will build the kernel while the <emphasis>modules_image</emphasis> option will build all modules located under <screen>/usr/src/modules/</screen>. So be sure that you do indeed want to rebuild any other modules that are located in source when you are ready to build your new kernel.</para>
|
||||
|
||||
<para>After some chugging, go up one level to <screen>/usr/src</screen> and you should see two new Debian packages that should look something like this:

<literallayout>
|

kernel-image-2.4.19-pre4_custom.1.0_i386.deb

</para>

<para>You first want to install the kernel image so you would type <screen>dpkg -i kernel-image-etc....</screen></para>
|

|

<para>Now install the modules by typing <screen>dpkg -i pcmcia-modules.etc...</screen></para>
|
||||
|
||||
<caution><para>There are a couple of assumptions that make-kpkg makes about your lilo.conf file. One is that you have not radically changed it. Make-kpgk will make make symbolics links from '/boot' where the actual kernel resides to 'vmlinuz' which is under '/'. In other words, under '/', you will see <emphasis>vmlinuz</emphasis> and <emphasis>vmlinuz.old</emphasis> which are symbolic links to the real kernel images under <emphasis>/boot/</emphasis>. Anyway if you have any questions ask me.</para></caution>

|

<para>You have downloaded the 11 Wlan project. Go a head and read the instruction, and put it under modules. Follow the instructions when you <screen>make config</screen> The one key is to make sure you specify the pcmcia-source as under <screen>/usr/src/modules/pcmcia-cs</screen> and not choose the default it gives you.</para>
|

|

<para>Go ahead and <screen>make all</screen> and <screen>make install</screen></para>
|

|

<para>I suggest you read the documentation that comes with it, but essentially, <emphasis>if you have a WAP that is connected to your DSL or cable modem then you have a <emphasis>infrastructure set up.</emphasis></emphasis> I found that it was best to edit the <screen>networks.opt</screen> under the <screen>/etc/pcmcia</screen> directory.</para>
|

|

<para>To make things easier edit the option

<para>From what I can gather,DesiredSSID means ESSID and it works when the WAP and link-sys pcmcia card share the same name.</para>

<para>2. If you don't, you might have had the same problem i did which was that there was no easy script to initiate the wlan0 device setup.

In other words, you might see something like this:</para>

<title>Wireless Access Point</title>
|

<para>Perhaps its it missing the forest for the trees, but I did not spend any discussion setting up the actual Wireless Access Point. The reason is that the documentation that comes with the WAP is well written. The only thing I haven't spoken about is enabling Wireless Encryption Protocol in the WAP (Wireless Access Point) which I really don't suggest as I don't think WEP has been properly set up in the drivers for the Pcmcia Wireless Cards. However, let me know if you have any problems and I will be glad to help.

<revremark>In part 2 of the HOWTO, the last item says make-kpkg --revision-custom.1.0 kernel_image when later on you used the correct one make-kpkg --revision=custom.1.0 kernel_image .

BEFW11S4- EtherFast? Wireless AP + Cable/DSL Router w/4-Port Switch. I really really like this WAP (Wireless Access Point). It is OS independent (read, linux friendly) and is configured using a browser so no need to touch Microsoft software at all, even to configure it. And if you don't know what a switch is, let me tell ya, they rock. Essentially they allow the NIC to communicate in both directions at the same time. I highly recommend one.

<para>You will also need some way to setup you IP address on your wireless card, I recommend either <screen>apt-get install DHCP-client</screen> to install the DHCP-client that will automatically configure your IP address, if you have a DHCP server. The WAP-11 hardware does provide DHCP server capabilities</para>
|
||||
|
||||
<para>Or at least have the <emphasis>pump</emphasis> application, which will also query a DHCP server and get you an IP address from the DHCP server. Note I tend to use <emphasis>pump</emphasis> when I am trying out new hardware to see if there is a connection. To test a particular device, say <emphasis>eth0</emphasis> I would type <screen>pump -i eth0</screen> where the option <emphasis>-i</emphasis> tells <emphasis>pump</emphasis> what device to try to get an IP address for. In this particular case, when I could not get Debian to automatically set up my wireless card, which was device <emphasis>wlan0</emphasis>, I would type <screen>pump -i wlan0</screen> and <emphasis>pump</emphasis> would try to set up the device. Pump is useful for troubleshooting. Examples of its usage are given later.</para>
|
||||
|
||||
<para>I also recommend you use the "kernel-package" package when you want to build your new kernel, which I will get to. This tool is very good and you should be using it anyway when you are building new kernel for the Debian distribution. You can install it by typing <screen>apt-get install kernel-package</screen> Also, be sure to read the documentation it comes with, in case I don't do a good job explaining how to use it, later in this document

<para>In order to use the wireless tools, like <emphasis>iwconfig</emphasis>, which will allow you tell how good your connection is, you need to enable support for <emphasis>Wireless LAN (Non-Ham Rasio)</emphasis>.</para>

<sect3><title>What <emphasis>NOT</emphasis> to Enable</title>
|

<para>One of the main stumbling blocks was to realize that the <emphasis>pcmcia support in the kernel is not as good as the pcmcia-source support</emphasis> that one gets when you build it from pcmcia-source.
|
||||
</para>
|
||||
|
||||
<para>I use either <screen>make xconfig</screen> or <screen>make menuconfig</screen> to configure my kernel, so when you configure your kernel, be sure to not have pcmcia support enabled under <screen>General setup</screen>
|
||||
</para>
|
||||
|
||||
<para>Nor do you want to select any particular pcmcia card under <screen>Network device support</screen>. I repeat you do not want this under the kernel and you will be building it when you download pcmcia-source.</para> <caution><para>Be sure to download all the necessary components before you take pcmcia support out of the kernel, otherwise, if you were using a pcmcia card for net access, you will not be able to connect to the Internet using the new kernel, until you have built both pcmcia support and module drivers for the wireless card</para></caution>

|

|

<para>Once you have configured your kernel just save and exit, and don't use make-kpkg yet! I will show you a good way to make sure sure everything builds well.</para>
|

<para>Follow the instruction in the make-kpkg documentation but essentially:</para>
|

<para>You need to be in the <screen>/usr/src/linux</screen> directory, then </para>
|

<screen>make-kpkg clean</screen>
|
||||
<para>to clean all the binaries out and prepare to build a new kernel, then:</para>
|

<screen>make-kpkg --revision=custom.1.0 kernel_image</screen>
|
||||
|
||||
<caution><para>Don't Do this Yet!</para></caution>
|
||||
|
||||
<para>We need to get the pcmcia-source ready to be built at the same time as the kernel is built. This is a very neat feature of make-kpkg!</para>

<sect1><title>Building PCMCIA-SOURCE</title>
|
||||
<para>First, be sure to download pcmcia-source, by typing <screen>apt-get install pcmcia-source</screen> This will download the source into <screen>/usr/src</screen> as <screen>pcmcia-source.tar.gz</screen></para>
|
||||
|
||||
<para>You now need to gunzip the file by <screen>gunzip pcmcia-source.tar.gz</screen> and then untar the file by <screen>tar xvf pcmcia-source.tar</screen></para>
|
||||
<para>You should see pcmcia-source unpacked into the directory <screen>/usr/src/modules/pcmcia-cs</screen></para>
|
||||
</sect1>
|
||||
|
||||
<sect1><title>Using make-kpkg to build the new kernel and pcmcia-source modules</title>
|
||||
|
||||
<para>Be sure the pcmcia-source is under /usr/src/modules.</para>
|
||||
<para>Go ahead and configure your kernel and be sure that pcmcia support IS NOT compiled in as an option in the kernel.</para>
|
||||
<para>To build the kernel and pcmcia-source, be sure you are under the <screen>/usr/src/linux</screen> or have a symbolic link from /usr/src/linux to whatever kernel source you have set up. Then type <screen>make-kpkg --revision=custom.1.0 kernel_image modules_image</screen></para>
|
||||
|
||||
<para>The <emphasis>kernel_image</emphasis> option will build the kernel while the <emphasis>modules_image</emphasis> option will build all modules located under <screen>/usr/src/modules/</screen>. So be sure that you do indeed want to rebuild any other modules that are located in source when you are ready to build your new kernel.</para>
|
||||
|
||||
<para>After some chugging, go up one level to <screen>/usr/src</screen> and you should see two new Debian packages that should look something like this:
|
||||
<literallayout>
|
||||
kernel-image-2.4.19-pre4_custom.1.0_i386.deb
|
||||
pcmcia-modules-2.4.19-pre4_3.1.31-7+custom.1.0_i386.deb
|
||||
</literallayout>
|
||||
</para>
|
||||
|
||||
<para>You first want to install the kernel image so you would type <screen>dpkg -i kernel-image-etc....</screen></para>
|
||||
|
||||
<para>Now install the modules by typing <screen>dpkg -i pcmcia-modules.etc...</screen></para>
|
||||
|
||||
<caution><para>There are a couple of assumptions that make-kpkg makes about your lilo.conf file. One is that you have not radically changed it. Make-kpkg will make make symbolics links from '/boot' where the actual kernel resides to 'vmlinuz' which is under '/'. In other words, under '/', you will see <emphasis>vmlinuz</emphasis> and <emphasis>vmlinuz.old</emphasis> which are symbolic links to the real kernel images under <emphasis>/boot/</emphasis>. Anyway if you have any questions ask me.</para></caution>

|

<sect1><title>Wlan Drivers for You Link-Sys Card</title>
|
||||
<para>You have downloaded the 11 Wlan project. Go a head and read the instruction, and put it under modules. Follow the instructions when you <screen>make config</screen> The one key is to make sure you specify the pcmcia-source as under <screen>/usr/src/modules/pcmcia-cs</screen> and not choose the default it gives you.</para>
|
||||
|
||||
<para>Go ahead and <screen>make all</screen> and <screen>make install</screen></para>
|
||||
|
||||
<para>I suggest you read the documentation that comes with it, but essentially, <emphasis>if you have a WAP that is connected to your DSL or cable modem then you have an <emphasis>infrastructure set up.</emphasis></emphasis> I found that it was best to edit the <screen>networks.opt</screen> under the <screen>/etc/pcmcia</screen> directory.</para>
|
||||
|
||||
<para>To make things easier edit the option
|
||||
<literallayout># Use DHCP (via /sbin/dhcpcd, /sbin/dhclient, or /sbin/pump)? [y/n]
|
||||
DHCP="y"</literallayout> to what I have, i.e., set it to yes.
|
||||
</para>
|
||||
|
||||
<para>The documentation talks about setting ESSID but when you edit the <screen>wlan-ng.opts</screen> you will only see

<literallayout>
|

#=======INFRASTRUCTURE STATION START===================
|

# SSID is all we have for now
|

AuthType="opensystem" # opensystem | sharedkey (requires WEP)
|
||||
DesiredSSID="howardnet"
|
||||
</literallayout>
|
||||
</para>
|
||||
|
||||
<para>From what I can gather,DesiredSSID means ESSID and it works when the WAP and link-sys pcmcia card share the same name.</para>
|
||||
|
||||
<para>At this point, you should reboot and should have a working link-sys card that gets its address via DHCP.</para>

<para>2. If you don't, you might have had the same problem I did which was that there was no easy script to initiate the wlan0 device setup. That is to say, if the card was recognized but you still did not get a connection and say that ifconfig showed wlan0 present but with no IP address. In other words, you might see something like this:</para>

<para>As you can see, the interface device, the Wireless pcmcia card, is noted, but there is no <emphasis>inet addr</emphasis>. The pcmcia software recognized the card, but it has not successfully connected with the Wireless Access Point.</para>
|

<para>I used the <emphasis>pump</emphasis> command to send a simple DHCP request to the DHCP server for the device in question. I used<screen>pump -i wlan0</screen> which essentially runs a simple DHCP request to set up that card, wlan0, in this case.</para>

<para>While I needed to use <screen>pump -i wlan0</screen> on my laptop, I did not need this when I set up the link-sys wireless WPC11 card on my girlfriend's laptop. She has a Link-Sys WPC11 version 2.5 pcmcia card.</para>

The only thing I haven't spoken about is enabling Wireless Encryption Protocol in the WAP (Wireless Access Point) which I really don't suggest as I don't think WEP has been properly set up in the drivers for the Pcmcia Wireless Cards.
