The Top 6 Alternative Firmwares For Your Router

The Top 6 Alternative Firmwares For Your Router: "

alternative firmware for routers Something that many consumers do not really think about is that hardware you buy in the store actually has software running on it as well. Any router you get – that’s the device that distributes the Internet coming into your house or business to multiple computers – has software running on it. Although “officially” the major companies will only support you and any problems you might have if you run their software, you can actually run software from other sources if it was designed to work on your device.

Let’s run over this list of alternative firmware for routers (firmware is just another name for software that runs on specific hardware) to see if you would benefit from the extra features it provides.

Why Use Alternative Firmware?

First of all, if you are not comfortable with voiding warranties, this article is not for you. Installing custom firmware can and will cancel that warranty, so if you have sunk all of your money into a new $150 router then it might be safer just to keep your manufacturer’s firmware on the device. Do not pass go, do not collect $200. There is also a chance you might brick your router.

If you are still reading this, I’ll assume you are cool with that and are willing to roll up your sleeves.

Turn A Regular Old Router Into An Enterprise Class Device

The first and main reason you might want to install alternative firmware is that you are adding features that although are possible on the consumer-grade hardware you purchased, the manufacturer decided not to add for a variety of reasons. They want to keep it simple and easy for Joe-consumer to configure and also because they sell much more expensive hardware to people who want those features. Luckily for you, people have been working on ways to get the fancy software on this plain hardware!

Some features that these alternative firmwares offer are:

QoS – Quality of Service – Allow some types of traffic to take priority over others.
Wireless Bridging.
Ability to Turn Into A Hotspot.
Adding SNMP (Monitoring protocol).
Detailed Diagnostic Tools.
And More…

Which Routers Will Work With Alternative Firmware?

This question greatly depends on the make and model of your router. By and far the largest consumer manufacturer of wireless routers is Cisco (formerly Linksys). Most of the alternative firmwares are made for these models since there are simply more of them out in the wild than any other kind. But, that being said, the chipsets which are the brains behind the routers are also used in other models, so sometimes you will see a crossover even to some brands that hardly anyone uses. But you are safest with one of the tried and true models that have been tested with each particular alternative firmware.

Bottom line is that you should check with each firmware to see which models it supports.

Let’s continue on to the different firmwares that are available:

DD-WRT

alternative firmware for routers

DD-WRT is by and far the most well known, distributed and tested of the alternative firmwares. It has been in development for a number of years now and is very stable. It is easy to install from your firmware upgrade page and include all of the features listed above. It is free and available for a number of routers – in fact probably the widest number of routers compared to other firmwares.

You can check to see if your router is supported by visiting their router database.

Tomato Firmware

firmware for router

Tomato works just like DD-WRT, is easy to install, and is under active development. Tomato isn’t quite as feature-rich as DD-WRT but makes up for it by being very user friendly while at the same time giving you advanced features like QoS and a shell.

Tomato is also not available on as many routers as DD-WRT. Check their homepage to see if your router (and version number, that is important as well) is listed as being compatible.

OpenWRT

firmware for router

OpenWRT is billed as the open router platform. Rather than trying to be everything to everyone, they have built a platform that others can then build packages onto. OpenWRT has a package management system that allows you to expand your router in any way you can think of, should you have enough knowledge and time to program it.

OpenWRT itself does not have a GUI (Graphical User Interface) built in. X-WRT is the extension which adds this functionality, and includes the ability to monitor your router as well as perform maintenance tasks over the web interface.

FreeWRT

FreeWRT is a fork of OpenWRT. It focuses more on having an open platform that experienced developers can build upon. It only has a command line, so it is not really geared for consumers. However if you have a need for a cheap remote access point, this might work for you.

Chilifire

If you want to run a Hotspot, Chilifire is the firmware of choice. This professional firmware allows you to offer for-pay or free hotspot access from your consumer router. The downside? They have a free version which supports limited methods of access and up to 10 users per month. If you want to offer more than that, or a pay version of a hotspot, they take a percentage of your revenue.

In return, you get a very professional firmware which will take the headache out of managing such an enterprise. Their firmware is available on many different routers, check their website for full compatibility information.

Gargoyle

alternative firmware for routers

Gargoyle is another firmware which adds bandwidth management quotas and network access rules to WRT54G and other routers. The web interface looks a bit dated, but the functionality is all there. It is a good alternative if you are looking for something different.

Whatever Works For You

Each package has its pros and cons. Obviously you are limited to what hardware you have or are willing to buy, but beyond that the choice is yours. If you are looking for firmware that is easy to use, check out Tomato. DD-WRT definitely has the most features and the most community support so is a great choice as well.

Angry Birds Nailed by The Oatmeal

Angry Birds Nailed by The Oatmeal: "

Do you know about The Oatmeal? They’re a pretty awesome group of folks who make illustrations and have an awesome, awesome blog. Occasionally they post something rather relevant to Android, like this Angry Birds infographic, and we just cannot resist. Take a peek at the first bit here, then go down the scale to the least likable birds in the pack. Can you guess which ones they are?

I’d have to say that this is basically the most accurate chart about the likability of Angry Birds that I’ve ever seen. From top to bottom, with the exception of that red bird, who I just cannot believe continues to come up later in the game, even fat, and think should be at the bottom of the chart, this chart is great. I must mention though that I don’t speak for everyone on our team, each person in the Android Community is of course an individual, and since this topic is an important one, I’ll leave it up to them to decide on their ideal chart.

Now you might notice the lack of a couple of birds on this chart. That is because we’ve left the tail end off as it is so common that someone will take a “The Oatmeal” chart in its entirety without linking back. In this case, we’ve decided to be incredibly noble and leave the last bit to them to display right over [here].

Space Shuttle Discovery’s Last Launch, Viewed From the Air [VIDEO]

Space Shuttle Discovery’s Last Launch, Viewed From the Air [VIDEO]: "

Imagine the delight of airline passengers when suddenly the Space Shuttle Discovery appeared, beginning its final voyage into space late Thursday afternoon.

Software developer Neil Monday shot this video aboard his flight from Orlando, which was late, but that’s a good thing — he and his fellow passengers were soon presented with this sublime moment of serendipity.

Best of all, did we hear that right? Drinks were on the house? This was Neil’s lucky day.

Picasa Web Albums now store unlimited small images and videos

Picasa Web Albums now store unlimited small images and videos: "

Recently, some users of Google's Picasa Web service noticed something odd. Like Gmail, Picasa Web tells you how much of your total available storage you're using. Something appeared to be wrong, however -- users were reporting having more free space than they previously had. It's common for Google to silently bump our upper storage limits, but how were these users showing the same number of photos and far less of their storage used?

Turns out it's a change in Picasa Web policy, and a darn nice one at that: images under 800 pixels and video clips under 15 minutes no longer count against your storage limit.

That's certainly great news for anyone who uses Picasa Web to store images for blogging -- 800px is plenty wide for most layouts. It also makes Picasa Web a great place to upload and share all the lower-resolution photos you snap on your Android phone.

As for the 15 minute videos (which arguably take up more more drive space than an 800px photo)? Google has a voracious appetite for video, and might just be hoping that Picasa Web users will help it maintain its dominant position in terms of serving videos on the Web.
