Some desktop computers don’t have built-in wireless connections installed by default, unlike laptops. In order to connect your PC to the Internet, most people use WiFi adapters or dongles, or even wires. But what if you don’t have a WiFi adapter? Good thing is that you can connect your desktop or PC to WiFi without an adapter, and we’ll teach you how in this article.
In the good old days before the widespread adoption of WiFi, computer users had to attach wires from the modem to their computer because that’s the only way they can access the Internet. But with WiFi available, those long Ethernet cables have slowly become a thing of the past, as you can easily connect to the Internet wirelessly.
The only time where using an Ethernet cable makes sense is if the modem or router is placed near your computer. But if the router is situated several meters away, then it’s better to just use a USB WiFi adapter if your computer doesn’t have one built-in.
WiFi adapters are cheap and you can buy one for around ₱300 ($6). The problem is that these USB WiFi adapters tend to heat up with prolonged use, so they often have a short lifespan of several months. It doesn’t matter if it’s from a well-known brand or not – it will break down in short order. In fact, we once bought a TP-Link WiFi adapter and it lasted for only six months.
So if you use a USB wireless adapter for your PC, it’s probably a good idea to have an extra adapter as backup because you will never know when it stops working. But if you don’t have a backup and your adapter no longer works, you can use your smartphone as a temporary WiFi adapter until you can buy a new one.
