48 <p><strong>NOTE: this guide is obsolete, a working driver is now included in the Linux
49 kernel tree (<a href="https://lkml.org/lkml/2009/4/18/121">since Linux 2.6.31</a>)</strong></p>
50 <h2>Introduction</h2>
51 <p>A USB to powerline bridge is a network device that instead of using an ordinary
52 Ethernet cable (CAT5 for example) or wireless LAN it uses the powerlines as a
53 network to communicate with similar devices. A more comprehensive explanation
54 of what it is and how it works you can find here:
55 <a href="https://en.wikipedia.org/wiki/IEEE_1901">https://en.wikipedia.org/wiki/IEEE_1901</a>.</p>
56 <p>Known products that use the Intellon 51x1 chipset:</p>
57 <ul>
58 <li>MicroLink dLAN USB</li>
59 <li>"Digitus network"</li>
60 <li>Intellon USB Ethernet powerline adapter</li>
61 <li>Lots of other USB-powerline adapters...</li>
62 </ul>
63 <p>To check if your device is supported:</p>
64 <pre><code>$ lsusb | grep -i 09e1
65 Bus 001 Device 003: ID 09e1:5121 Intellon Corp.
66 </code></pre>
67 <p>If the vendor (09e1) and product (5121) ID match then it's probably supported.</p>
68 <h2>Installation</h2>
69 <p>Get drivers from the official site:
70 <a href="http://www.devolo.co.uk/consumer/downloads-44-microlink-dlan-usb.html?l=en">http://www.devolo.co.uk/consumer/downloads-44-microlink-dlan-usb.html?l=en</a> or
71 <a href="downloads/int51x1/dLAN-linux-package-v4.tar.gz">mirrored here</a>.
72 The drivers from the official site were/are more up-to-date.</p>
73 <p>Extract them:</p>
74 <pre><code>$ tar -xzvf dLAN-linux-package-v4.tar.gz
75 </code></pre>
76 <p>Go to the extracted directory and compile them:</p>
77 <pre><code>$ ./configure
78 $ make
79 </code></pre>
80 <p>Depending on the errors you got you might need to <a href="downloads/int51x1/int51x1.patch">download</a> and apply
81 my patch:</p>
82 <pre><code>$ cd dLAN-linux-package-v4/ (or other path to the source code)
83 $ patch < int51x1.patch
84 </code></pre>
85 <p>Try again:</p>
86 <pre><code>$ ./configure
87 $ make
88 </code></pre>
89 <p>If that failed try:</p>
90 <pre><code>$ ./configure
91 $ KBUILD_NOPEDANTIC=1 make
92 </code></pre>
93 <p>If that went OK install the drivers (as root):</p>
94 <pre><code># make install
95 </code></pre>
96 <p>Check if the "devolo_usb" module is loaded:</p>
97 <pre><code>$ lsmod | grep -i devolo_usb
98 </code></pre>
99 <p>If it shows up then it's loaded. Now check if the interface is added:</p>
100 <pre><code>$ ifconfig -a | grep -i dlanusb
101 dlanusb0 Link encap:Ethernet HWaddr 00:12:34:56:78:9A
102 </code></pre>
103 <h2>Configuration</h2>
104 <p>It is assumed you use a static IP, otherwise you can just use your DHCP client
105 to get an unused IP address from your DHCP server. Setting up the interface is
106 done like this (change the IP address and netmask accordingly if it's
107 different):</p>
108 <pre><code># ifconfig dlanusb0 192.168.2.12 netmask 255.255.255.0
109 </code></pre>
110 <h2>Checking if the network works</h2>
111 <p>Try to ping an IP address on your network to test for a working connection:</p>
112 <pre><code>$ ping 192.168.2.1
113 PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.
114 64 bytes from 192.168.2.1: icmp_seq=1 ttl=30 time=2.49 ms
115 64 bytes from 192.168.2.1: icmp_seq=2 ttl=30 time=3.37 ms
116 64 bytes from 192.168.2.1: icmp_seq=3 ttl=30 time=2.80 ms
117 --- 192.168.2.1 ping statistics ---
118 3 packets transmitted, 3 received, 0% packet loss, time 2005ms
119 rtt min/avg/max/mdev = 2.497/2.891/3.374/0.368 ms
120 </code></pre>
121 <p>You can now set up a network connection like you normally do with any Ethernet
122 device. The route can be added like this for example:</p>
123 <pre><code># route add -net 0.0.0.0 netmask 0.0.0.0 gw 192.168.2.1 dlanusb0
124 </code></pre>
125 <p>Change the IP address of your local gateway accordingly. Also make sure your
126 nameserver is set in /etc/resolv.conf, something like:</p>
127 <pre><code>nameserver 192.168.2.1
128 </code></pre>
129 <p>Test your internet connection by doing for example:</p>
130 <pre><code>$ ping codemadness.org
131 PING codemadness.org (64.13.232.151) 56(84) bytes of data.
132 64 bytes from acmkoieeei.gs02.gridserver.com (64.13.232.151): icmp_seq=1 ttl=52 time=156 ms
133 64 bytes from acmkoieeei.gs02.gridserver.com (64.13.232.151): icmp_seq=2 ttl=52 time=156 ms
134 64 bytes from acmkoieeei.gs02.gridserver.com (64.13.232.151): icmp_seq=3 ttl=52 time=155 ms
135 --- codemadness.org ping statistics ---
136 3 packets transmitted, 3 received, 0% packet loss, time 1999ms
137 rtt min/avg/max/mdev = 155.986/156.312/156.731/0.552 ms
138 </code></pre>
139 <p>If this command failed you probably have not setup your DNS/gateway properly.
140 If it worked then good for you :)</p>
