In fact, I once bought a TP-Link WiFi adapter and it lasted for only six months. It doesn’t matter if it’s from a well-known brand or not – it will break down in short order. 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. WiFi adapters are cheap and you can buy one for around ₱300 ($6). 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. The only time where using an Ethernet cable makes sense is if the modem or router is placed near your computer.
