The personal computer has been around for nearly 40 years. In that time, we’ve adapted to all kinds of platforms and devices.
The everyday consumer has harnessed the internet, learned Microsoft Office, and mastered the iPhone. Every year, electronics companies throw us a curveball, like the arsenal of smart TVs or the ability to send money through Facebook Messenger.
Certain skills are reserved for pros. You wouldn’t necessarily think to ask about them.
But for folks who like technology hacks (like myself), you may find this list extremely helpful, especially if you want your electronics to run as smoothly as possible.
1. Change your DNS to double your internet speed
When your internet connection slows down, you may struggle to find the cause. Is it the router? The modem? Your computer itself? Has a mischievous neighbor broken into your network and started streaming movies all day?
Well, there’s one nifty way to speed up your Wi-Fi connection. Change your “domain name system,” or DNS.
This system transforms complicated IP addresses into memorable site names. The problem is that some DNSs are more effective than others.
To fix it, you can use Google’s “namebench” to test whether a certain DNS is working well. Want to learn how to use it?
2. Wipe data from your printer
I know what you’re thinking: You’ve got to be kidding me! What could my printer possibly be storing? Does a printer even have a hard drive?
The truth is, you can probably sell or give away your printer and no harm will befall you. Printers don’t usually store much information, and most of this is erased the moment you switch it off. But some all-in-one printers do preserve a small amount of data, and if you have tax forms or recent banking documents stored in that device, you can bet a hacker wants it.
To be on the safe side, do a “hard reset.” Printers are a wide-ranging appliance, and each one works a little differently. I’ve got you covered though.
3. Destroy your hard drive (literally)
You’ve probably heard that you should erase your hard drive before unloading your computer, and that is absolutely true. Whether you’re selling it on Craigslist or donating it to Goodwill, you’re wise to delete everything from your retired machine.
But what if you’re recycling your computer? For hands-on machinists with some power tools, this is your chance to literally take your computer apart. Do what you will with its components.
Dissect the hard drive, drill holes in it, or smash it up with hammers. That will destroy the data for good. Do take safety precautions.
4. Make an old PC run faster
Some people like to buy a used desktop or laptop because they don’t need the latest bells and whistles. A word processor, a trustworthy browser and a decent music library are pretty much all they want.
But computers slow down over time, especially when they age a few years. So what happens when you have an older PC and you want to speed up its operations?
Some techniques are actually pretty simple, especially for Windows-based PCs. Start by deleting the files and programs you never use. We tend to accumulate a lot of junk that we don’t really need, and these can weigh down your system’s performance.
You can also save your photos and videos to a cloud service, which will free up gigabyte after gigabyte of hard drive space. Cloud services are handy and affordable, and you can save thousands of high-volume files on the internet. When you eventually decide to invest in a new computer, you can easily fetch those photos later on.
But that’s not all. You can also defragment, eliminate malware, and even reinstall Windows.
5. Hack your Wi-Fi passwords
When your router is first set up, your installer usually hands you some outrageously complicated password. The letter and numbers are randomly assigned and follow no pattern. Unless you have a photographic memory, you’ll probably never remember it.
So what happens when your Wi-Fi cuts out, and you completely forget where you put that darn password? Unless it’s printed on the back of the router itself (as many are), you will never remember the exact combination of letters and digits. Now what?
A surefire trick is to reset the router to factory settings. Usually, you can find a small pinhole on the device, and you’ll need to use something small and skinny (like a paperclip) to press the button inside for 15 seconds.
This will erase all the information, including the password and the router’s history with your computer. From there, you’ll have to set up the router like it’s a brand new device.
That might take some work, especially if you’re not sure how to set up your router from scratch. If you’re more familiar with coding, you can consult your hard drive for the missing Wi-Fi password.
It may sound like cloak and dagger, but it’s a straightforward process. On Windows, you can open a command window and use a simple code to retrieve any saved password. On a Mac, you’ll find the similar “Terminal” window.
