Antenna setup for laptop internet connection
The USB internet/Bluetooth antenna won't help much if your laptop already has good built-in receivers. External antennas usually only matter when those internal ones aren't performing well.
It really depends on the situation. I had a friend with a desktop that used a budget Wi-Fi card. His computer was placed far from his router, so I built a big foil dish and attached it behind his desktop. The result was a noticeable boost in Wi-Fi speed. Outside of that, I’m not sure if there are better aftermarket options or if they’d actually help compared to your current laptop.
USB networking devices often perform poorly. They tend to overheat and malfunction. I don’t suggest using them unless there’s no other option. You could consider replacing the WiFi card in your laptop, which might be something worth checking if you’re considering an upgrade. Some laptop makers provide compatibility lists for certain cards.
Her sister's laptop arrived with a weak wireless N card. Many AC cards were included in the package. It seems her laptop was probably made before wireless connectivity became common.
