Overview
A tower tucked under a desk, far from the router, is where a USB adapter on a cable helps, since the antenna can be placed at desktop level. The adapter brings the newer Wi-Fi standard to the machine without opening the case.
Choose it for a plug-in upgrade that needs no case opening. The limit is that it supports only Windows, works best on a fast USB port and is dual-band rather than tri-band.
Who it's for
A student or home user with a prebuilt tower, a weak built-in card and no free slot will use the plug-in design and the antenna. Buyers on other operating systems, or who want Bluetooth, should look at a different adapter.
Pros and cons
- Plug-in USB design
- Newer Wi-Fi standard
- Cable for placement
- Long warranty term
- Needs a fast USB port
- No Bluetooth listed
Performance notes
A USB adapter can move the antenna away from a metal case, which improves reception. A fast USB port is needed, because a slower one limits throughput, and the built-in card should be disabled first to avoid conflicts. MU-MIMO helps when several devices share the network.
