Custom Firmware Options for Your Wireless Router

For most clients a decent remote switch is the one that you set up in a couple of simple strides and forget about it more or less long on the web. Any conventional purchaser grade remote switch will carry out the occupation alright more often than not, while more curious people can at present change around a couple setup choices to ensure things are running easily.

But beyond the stock features that came with your router, there are many things that the hardware you bought might be capable of; it just happens that the manufacturer decided not to include them for a variety of reasons that go from keeping things simple, to the fact that they sell more expensive models to people who need those features.

Luckily for you, people have been working on ways to get the fancy stuff running on your average $60-$100 device. After a relatively simple upgrade to a free third-party firmware, you’ll be able boost your wireless signal, prioritize what programs get your precious bandwidth, and do lots of other stuff usually reserved for pro-grade wireless routers.

Below you’ll find a selection of the most popular options out there, along with some basic information and strong points. Since the installation procedure will vary by device, we can’t practically include instructions for all supported hardware, but we’ll point you in the right direction, so you can see if your router is supported and follow the installation notes.

We should note that installing a custom firmware will likely void your warranty and if anything goes wrong there’s also a chance you might brick the device. With that said, if you’re feeling adventurous (and if you are reading TechSpot we have to assume you are open to this sort of things), proceed at your own risk.

DD-WRT

DD-WRT is by far the most popular and widely tested of the bunch. This Linux-based firmware currently supports more than 200 different devices and is so well developed and documented, that it comes pre-installed with routers manufactured by Buffalo Technology and a few others. DD-WRT has a crazy amount of features, too many to list here, but some highlights include support for IPv6, advanced QoS for bandwidth allocation, radio output power adjustment (to boost your Wi-Fi signal), bandwidth monitoring, a variety of Wi-Fi hotspot services and a lot more.

You can check if your router is supported by visiting the Supported Device List in the DD-WRT wiki, and also make use of their Router Database, which will help you find particular instructions for your model and revision.

Tomato

Tomato is a small, lean and simple replacement firmware for Linksys WRT54G/GL/GS, Buffalo WHR-G54S/WHR-HP-G54 and other Broadcom-based routers. It does almost everything DD-WRT can, but with a simplified web interface that makes heavy use of AJAX and also features a pretty nifty SVG-based graphical bandwidth monitor. Other features include advanced Quality of Service rules, Wi-Fi signal boosting, access restrictions, and wireless client mode.

Tomato is also not available on as many routers as DD-WRT. Check their homepage to see if your router model and revision is listed. Also check the Frequently Asked Questions and the included readme before installing.

OpenWRT

OpenWRT is a customizable firmware mainly installed on embedded devices and aimed mostly toward advanced users. It primarily uses a command-line interface, but also features optional web-based GUI interfaces via separate packages such as LuCI or X-Wrt, allowing easier access to a wide range of features. One that stands out is its fully writeable file system, which allows for installation of updates without rebuilding and flashing a complete firmware image.

The OpenWRT project also provides regular bug fixes and updates, even for devices no longer supported by their manufacturers. A list of compatible routers is available here along installation instructions for each model.

Gargoyle

Gargoyle was originally available as a third web interface for OpenWRT but it’s now being released as a full firmware image for routers such as the Linksys WRT54G series and the Fonera. Among its features are dynamic DNS, quality of service, access restrictions, bandwidth quota management, bandwidth monitoring tools, and an AJAX-based GUI.

Gargoyle’s developer says the firmware’s primary focus is to provide a polished interface for advanced features that is at least as easy to configure as any existing firmware. A list of compatible devices is available here — it supports a bunch of Broadcom and Atheros based routers — and installation instructionscan be found on this page.

There are several other options that might satisfy more specific needs. For example, Chilifire is a good alternative if you want to run a hotspot, as it allows you to offer for-pay or free Internet access points from your consumer router.

Shrewd Tips To Make Dropbox More Useful

Dropbox has turned into a key application on my framework as far back as I initially attempted it over two years prior. In case you’re new to it, it’s a cross-stage instrument that demonstrations like a normal envelope on your machine and runs discreetly out of sight. You can oversee records inside this envelope simply like somewhere else on your machine (include, alter, duplicate, and erase) and changes will be synchronized continuously between every other PC on which you are running the Dropbox programming.

That alone makes it precious for my every day figuring needs, yet with a little resourcefulness, you can utilize Dropbox to do substantially more. Underneath I’ve ordered some helpful tips and traps to take advantage of this stunning free application.

Autostart torrent downloads

Many BitTorrent clients have an option to monitor a specific folder on your computer and automatically start downloading any torrents copied to it. In uTorrent for Windows, for example, you can find it in the Directories section on the left-hand pane of the preferences window. Simply check the box for “Automatically load .torrents from:” and choose the directory where you’ll be saving .torrent files inside your Dropbox folder.

There are just a couple of extra steps you need to take care of to keep things running smoothly: first, set your client to save new downloads and completed downloads on a folder outside of Dropbox so you don’t use up your quota. And second, head into the UI Settings section of the preferences and uncheck the option for “Show a window that displays the files inside the torrent” so downloads start automatically. Now, as long as you keep your BitTorrent client running you can start downloads from another computer by adding Torrents to the monitored folder inside Dropbox.

You can also upload torrent files from the Dropbox web interface, so you could even do this from a computer where you can’t install Dropbox, or upload them from your iOS, Android or BlackBerry smartphone.

Send and receive files

If you transfer files frequently with clients or any non-Dropbox user, but email and FTP just wont cut it due to file size or complexity, there are a number of services designed specifically for the purpose of sending files directly to your Dropbox. With DropItToMe, for example, you can setup a custom upload URL (like ‘http://www.dropittome.com/somethinghere’) with optional password protection that you can give out to people.

FileStork works much in the same way but allows you to setup one-time or permanent upload addresses — though they are not customizable. Both services allow other people to upload files into your Dropbox without the hassle and risk of actually sharing a folder, and a medium to bridge the gap between users and non-users of Dropbox.

Alternatively, AirDropper offers a more polished interface and lets you create your own airdropper.com/yourname page with your own branding for sending and receiving files. It’s the most feature-packed of all three and allows files up to 2GB each, whereas the others are capped at 75MB. Unfortunately, it costs $9 per month, which seems a little steep honestly. (Hint: you can still access the beta for free at ‘http://beta.airdropper.com’)

Make it your default Documents folder

Many people use their operating system’s documents folder to store and access their most frequently used or most important files. To make sure they are always backed up and synchronized on all your computers you can actually change your My Documents folder to be the same as your Dropbox folder, or be in a folder inside your Dropbox.

To do this in Windows 7 or Vista, just right-click on your “My Documents” folder and select Properties, then on the Location tab you can specify the new file path. In Windows XP it’s pretty much the same process but you’ll need to change the Target value instead. It’s a simple “trick” but can come in handy if you want your whole documents folder synchronized instead of just the files that you specifically move to the Dropbox directory.

Synchronize your KeePass passwords

Users who rely on KeePass to maintain a password archive of sites or services they use can combine it with Dropbox to have it accessible from multiple computers at all times. Simply save your database to Dropbox, and on any other computer that you plan to use KeePass on open the app and select File -> Open Database, then point it to the synced KeePass database file that you added to Dropbox.

KeePass doesn’t automatically update your passwords when it’s open, so if you make a change on one computer and then make a change on the other without re-opening the new database, you’ll end up with a conflict. To get around this you’ll have to set a reasonable timeout so the database is locked after a period of inactivity. Then head to Options and on the Advanced tab check the box that says “Automatically save when closing/locking the database”.

KeePass saves your password in an archive with AES 256-hit encryption. Even if Dropbox servers were to be hacked, as long as you pick a long, strong password you should be safe for a few thousand or million years.

Give syncing powers to apps that don’t have any

KeePass is just one example of how Dropbox can provide syncing powers to programs that don’t have any such functionality. I did this for a relative who wanted to access his business contacts database from Sage’s ACT! on two different notebooks — and I’m talking about a really old version that came on floppy disks since he didn’t see a reason for upgrading. As long as you can move the location of a program’s data file you’ll probably be able to sync using Dropbox.

Alternatively, a program called Dropboxifier can streamline that process by moving a data directory or file into the Dropbox directory, and creating a symbolic link afterwards that points from the source folder to the new Dropbox folder location. The result is that you’ll be able to synchronize stuff like saved games, browser profiles, IM chat logs, and more. Dropboxifier works on Windows Vista and Windows 7, provided you have the free .Net Framework 4.0 installed.

Things That Can and Cant do of Water Cooling

Cooling PCs has advanced in the most recent ten years to the point where there are more alternatives to fulfill a wide range of necessities. All in One (AIO) water cooling units specifically have picked up ubiquity among clients who need push frequencies higher while keeping their CPUs cooler. They’re anything but difficult to begin with as they are for the most part fitting and play. While things have become less demanding in the water cooling diversion, there are still numerous things that should be thought about before hopping into guarantee you can get the most execution from your own framework.

Water cooling systems — whether they are a custom loop or an AIO — all follow the same basic principles. You have the reservoir, the pump, the radiator, the fans, some tubing, a block (for either the CPU, GPU, or both), and the water itself. Generally on different versions of AIOs or custom loops you may see some of these features as barely noticeable, for example, many AIOs have very small reservoirs that are not nearly as prominent as with other custom loops, but they are usually all there.

After years of working with water cooling kits, here are some important tips to help you get the most out of your system.

Mounting the Block

When mounting the block you want to have the best contact between the block itself and the component you’re trying to cool. This does not mean that it needs to be extremely tight so it’s near impossible to lossen the screw, instead you just want to make sure it has the right amount of tightness so the system’s heat is transferred properly to the radiator for cooling.

Do: Tighten the block down starting first at opposite ends of the block and then add the other two. Tighten the screws down until they get a little snug.

Don’t: Force the screws to tighten to the point they will no longer move. Overtightening the cooler can cause the paste to leak out the sides causing poor contact between the block and CPU and it can also cause problems with the CPU and motherboard contact.

Mounting the Radiator into the Case

When choosing where to mount the radiator there are many options available, however there are some locations that will allow the system to work bettter for both the water cooled components and the rest of the system as well. Some users choose to mount the radiator to pull in fresh air from the outside; others choose to have it push air out of the case. Which method works best will come down to your own system as you want to make sure you don’t end up impeding other components from cooling properly.

Do: Pick a place for the radiator that allows as little bending as possible on the lines. You can normally adjust the lines to where they can sit comfortably in the system especially on AIOs. You just want the lines to keep their shape while bending so as to not impede water flow.

Do: Mount the radiator so its airflow is not impeded by other devices in the machine. One of the best spots on a machine is the top of the case.

Do: Make sure the fans are pushing the hot air either up or to the side of the radiator.

Do: Tighten the mounting screws snugly enough so the radiator cannot move to alleviate potential vibrating/noise.

Don’t: Bend the tubes much. The harder the bend, the more likely it is to kink. Even with “Kink Resistant” tubing, it’s still possible that bent tubes will reduce water flow. If you are worried about this, you can always use anti kink coils which can help keep tubing from kinking.

Don’t: Mount the radiator too close to other devices. If you mount the radiator and its fans too close to a device pushing air in the opposite direction it can cause a stalemate with the air and in turn give you higher temperatures. The radiator needs to be put in a way it is not impeded by any device in the system to ensure you get the most performance out of the cooling system.

Don’t: Have the radiator push its air down. This goes against the laws of physics and can cause the radiator to stalemate air. Hot air likes to rise so if the radiator is dissipating heat that air is going to travel up at some point. You want the radiator and fans to have as little trouble as possible when moving hot air out, which will improve temps and keep the system quieter.

Don’t: Overtighten the screws when mounting it. Generally the screws that are sent with the radiators are designed to fit within the specifications of the kit it comes with. Overtightening the screws can have adverse effects like bending the radiator, puncturing the radiator, or causing warping on the radiator and its fans which can lead to damage.

Placement of the Fans

When it comes to fans the first concern is the configuration they should be in. Some people prefer to have the fans pushing air through the radiator, others choose to have the air pulled through the radiator, and the rest choose to have both.

In practice the results are almost the same using any of these methods. If you want to use a push and pull system on your radiator, this will give you a more consistent speed of air moving through the radiator and makes it less likely for air to escape from the sides of the radiator. More and more fans today are designed to provide better air pressure whether they are going on a radiator or computer heatsink. So while your results will vary depending on the fans, using a push and pull setup on your radiator is not necessary in most cases but can give a little boost to get the best possible performance out of your cooling system.

Do: Mount the fans pushing in a direction where hot air can travel freely (Straight up or to the side). The fans should be impeded as little as possible when pushing or pulling air through the radiator to give the most performance for the whole system.

Don’t: Mount the fans pushing air down. This can cause air to stalemate in a case as the air will attempt to travel back up in the case and can clash against other components (like graphics cards with coolers that push air to the sides of the card in the case), which can result in higher temps of not just the liquid cooling loop but the other components as well.

Testing/Finalizing your System

After you complete your first water cooling setup it is important to test out its functionality regardless if it was an AIO or a full custom loop. While reliability has improved significantly over the years, there is still the chance of a dead component that could hinder your system.

There is also the chance that a part is mounted improperly or that a component conflicts with your positioning of the radiator and fans, which can cause lower than normal cooling performance. Watching the device power up for the first time and begin moving water can immediately let you see if there are any issues (leaks, weird noises) that need addressing.

After that, look at the idle temperatures from the hardware you are cooling as that can immediately show if there’s a problem. Your machine should be running at a lower temp than before installing the water cooling system, usually below 50C depending on the device. You can check around what others have achieved with similar setups to get a general idea.

Do: Test your setup before proceeding to your normal computer routine. You should check your idle and load temps to make sure they are staying within the manufacturer’s safe range and that the system runs in the expected range for the cooling you have bought/made.

Don’t: Immediately return to your normal computing routine or overclock without first confirming functionality. While modern day processors and graphics cards are equipped well to keep their temps down in the event of an issue with cooling, running devices near their temp limits can cause damage and eventually ruin the component.

Nowadays there’s an abundance of water cooling solutions to fit most people’s needs and a range of form factors. Whether you’re after a silent system, serious overclocking, or simply some geek cred and sleek looks, if you’re just exploring this world, going with an AIO package is probably the safest bet, but you can get as involved as you want all the way to cutting tubing and building your own loop to cool your CPU, GPU, motherboard, and more.
