WiFi
Here we encounter WiFi's Achilles heel, if an invisible wave pattern can be said to possess anatomy. WiFi's reliability varies wildly based on factors including router age, wall thickness, microwave oven usage, and the apparent vindictiveness of the universe during important video calls. The technology exhibits what engineers politely term 'environmental sensitivity' and what users more colourfully describe in terms unsuitable for documentation. Signal dropout during crucial moments has become so culturally significant that 'WiFi problems' serves as a universally accepted excuse for professional failures. The 2.4 GHz band in particular suffers from interference with everything from baby monitors to Bluetooth speakers, creating a cacophony of competing signals in modern homes.
