Though more router manufacturers are making routers easier to set up and configure — even via handy little apps instead of annoying web-based interfaces — most people probably don't tweak many options after purchasing a new router.

Updating your PC is so straightforward that, depending on your operating system, it'll be taken care of for you automatically (aggressively so).

A new botnet, boasting an army of 500,000 remotely-controlled routers in 54 countries, has been discovered.

The viral tweets, the breaches of my privacy by Facebook and god, all those images of delicious donuts on Instagram. I imagine that's what Julian Assange thought when they cut off his internet earlier this week.

What should you do when your internet goes down to get yourself back online as quickly as possible?

There are literally thousands of Wi-Fi routers on the market. Look through the catalog of an office supply or local computer store, and you'll be faced with a plethora of choices.

Dear Lifehacker, are you able to recommend a good modem? I'm with Internode. I need a modem router, with wired ports and wireless, and support for naked DSL. In terms of the wi-fi area it needs to cover, I'm in a pretty small townhouse. Someone's buying it for me as a gift, so price is flexible.

Is it awesome or awkward when your router has more grunt than your notebook? Well, depending on how old your laptop is and your fondness for $700 networking hardware, this unusual dream can be yours via ASUS' upcoming Rapture GT-AC5300.

The first router I saw was in the mid 1990s. The company I worked for was a very early adopter of the Internet, at least in the commercial world. After spending a couple of nights with the network manager and his technical support guy dragging Ethernet and coaxial cables through the office roof space we hooked everything up through a router that cost more than most of us earned that year. Today, more than 20 years later, a faster and more capable device costs less than a day's pay for some of us.

DD-WRT is a Linux based alternative OpenSource firmware that works with most WLAN routers.

Here's how it works.

Back in 2015, the US FCC introduced new guidelines that looked like a threat to anyone wanting to hack and install open firmware on their routers. They backed off, but a lot of manufacturers are still locking their devices down, just in case. Linksys, the company announced last week, isn't one of them.

Building your own router might sound like a fools errand, but Ars Technica found that it was not only pretty simple, it also produced better results than most commercial options.
