Linux on the Linksys WRT54GL

In a move to put Linux on everything I own, I just installed DD-WRT on my Linksys router. DD-WRT is free Linux-based firmware for several wireless routers, most notably the Linksys WRT54G family. Many of DD-WRT's features are not included in typical router firmware. These features include support for the Kai network, daemon-based services, IPv6, Wireless Distribution System, RADIUS, advanced quality of service, radio output power control, overclocking capability, and software support for a Secure Digital Card hardware modification.


The Linksys WRT54GL was released in 2005 to support third-party firmware based on Linux. Its fully compatible with DD-WRT. This guide also works for a couple of other LinksysWRT54G, models WRT54G v4 and earlier, but the WRT54GL is the the preferred router to buy/use.
If you want to see what other routers are DD-WRT compatible go here.

Increase your RAM? free of cost…Really Worth It!!!!

A Very useful tip . Please try this and use RAM efficiently. Now this is called a tip of the year! While working with the Task Manager I observed the following. You can also try it out. 1.Start any application, say Word. Open some large documents. 2.Now start the Task Manager processor tab and sort the list in descending order on Memory Usage. You will notice that Winword.exe will be somewhere at the top, using multiple MBs of memory. Note down the number. 3.Now switch to Word and simply minimise it. (Do not use the Minimize All option of the task bar). 4. Now go back to the Task Manager and see where Winword.exe is listed. Most probably you will not find it at the top. You will typically have to Scroll to the bottom of the list to find Word. Now check out the amount of RAM it is using. Compare it with the original. Surprised? The memory utilisation has reduced by a huge amount. 5.So where is the tip of the year? Simple? Minimise each application that you are currently not working on ...
