Etisalat (rebranded as e&) operates the dominant FTTH network in the UAE, with near-universal fibre coverage. Real-world speeds are excellent on a wired connection; Wi-Fi is the most common bottleneck.
Etisalat's stock ONT/router is fine but Wi-Fi 5. Add a Wi-Fi 6 mesh and you'll see real gigabit throughput.
Domestic routes are fine; international hops via Fujairah landing stations get congested. Affects gaming on EU/US servers far more than streaming.
Etisalat's regulated routing adds latency to some international destinations. Choose a VPN with Dubai or Singapore endpoints to minimise hops.
