⚠️ Things to Watch Out For
🐢 USB 2.0 limits speed—use USB 3.0 for full Gigabit performance
🧯 Some adapters lack support for jumbo frames or advanced networking features
🧪 Driver issues may arise on legacy OS or unusual hardware
🔌 Dongle-style adapters can strain ports—use with care
🧼 Avoid cheap builds—poor shielding can introduce interference
 
🛠️ Quick Tips for Beginners
🔍 Identify RJ45 by its wide clip-in connector; USB by its shape (A or C)
🧭 Plug adapter into USB port, then connect Ethernet cable
🧪 Test with speed check tools to verify performance
🧰 Keep one in your tech kit for travel or emergency use
🧼 Store in padded pouch—protect internal chipset from impact
