<p>Apologies for the bad quality.  I really was installing DD-WRT whilst recording, for the first time!  I tried to tidy it up but it&#8217;s still fairly rough!</p>

<li>Search for your Router (or one you might want to buy), in my case the <a href="https://www.newegg.com/Product/Product.aspx?Item=N82E16833124190">Linksys WRT54GL from NewEgg</a> (note:  NOT a sponsored link and other shops are available).</li>

<li>Notes:  Initial flashing &#8216;Mini Generic&#8217; via web interface.   Give it at least 2 mins after reboot!</li>

<p><span style="line-height: normal; font-size: x-small;"><span style="font-size: small;"><span style="line-height: 19px;">Thoughts.</span></span></span></p>                       
<li style="padding-left: 30px;"><span style="font-size: small;">The router restarts itself when you flash the firmware, which is nice.</span></li>                                  
<li style="padding-left: 30px;"><span style="font-size: small;">If you change the IP of the router you may have to disconnect and reconnect the network through linux to force it to update the new IP address.  Don&#8217;t forget like I did!<br />                                                                                                                   
</span></li> 
<li style="padding-left: 30px;"><span style="font-size: small;">To set up a Wii via Wi-Fi you need to set the router up as &#8216;Ad-Hoc&#8217; else it doesn&#8217;t seem to show in the Wii menu.</span></li> 
<li style="padding-left: 30px;"><span style="font-size: small;">I had problems with my previous router being 192.168.1.1 and the DSL being 192.168.0.1 making me hard reset and set the details back up.  Might be unrelated to this, however changing the IP to 192.168.10.1 for the router and keeping 192.168.0.1 for the DSL resolved this problem.</span></li> 
<li style="padding-left: 30px;"><span style="font-size: small;">It was pretty damn simple!  At least a lot simple and faster then installing windows!</span></li> 
<li style="padding-left: 30px;"><span style="font-size: small;">Total time isn&#8217;t too long, but I&#8217;d recommend having a second router on hand (if you can) to keep internet access in case things go hairy!<br />
