Networks & Telecoms

OPINION: No matter how good your Wi-Fi is, your network connection will almost certainly be better with an ethernet cable. Use Wi-Fi where you need to use Wi-Fi (like your tablet, phone, or laptop). Use ethernet where you can (like your TV, games console, computer, burglar alarm, security cameras).
