⚙️ Use‑Case Notes / Pros & Cons
Pros:
-
Brings fast wired Ethernet to devices that lack built‑in RJ45 (e.g. ultrabooks, tablets, mini PCs).

More stable connections than WiFi, especially in congested networks or for large data transfers.
-
USB 3.0 ensures that the adapter itself isn’t bottlenecked by the USB interface (assuming the host supports USB 3.0).
-
Portable and compact.
Cons / Considerations:
-
To fully get 1000 Mbps, you need good quality Ethernet cable (Cat‑5e / Cat‑6) and compatible network equipment.
-
On older OS or nonstandard setups, may require driver installation.
-
Performance may be lower when using USB 2.0 ports vs USB 3.0.
