Average Internet Speed in Thailand

Internet in Thailand: what the data shows

At a median 22.5 Mbps download, Thailand sits below the midpoint of the table: #77 of 119 ranked countries, 34% below the global median of 33.9 Mbps. The world's fastest median belongs to the United States at 144 Mbps, more than 6× the speed measured here.

Uploads keep pace with downloads (18.8 vs 22.5 Mbps): connections here are balanced, just not fast. Median latency is 70 ms. That is on the high side: pages and video still load, but calls, gaming and screen sharing carry a visible delay.

The provider table stretches wide: AIS leads the measured ISPs at 137 Mbps, 6.1× the national median. A spread like that opens up where full-fibre networks compete against legacy copper and cable, so which network serves your address changes more than any plan upgrade.

Desktops test faster than phones here (79 vs 16 Mbps): home Wi-Fi and wired links outrun the mobile networks that carry 73% of tests. By operating system, Windows devices record the quickest median (89 Mbps) while Android sits at 15 Mbps, usually a proxy for the networks and hardware each platform rides on rather than the software itself.

Tests from Thailand most often reached the Singapore test server (50% of the top-server mix), so the figures reflect the routes everyday traffic actually takes. Every number on this page is a median of single-stream browser tests from the H1 2026 window: Real-World Speed, measured on the open internet rather than inside an ISP's own network. It reads lower than peak-rate tests by design, and every country is measured with the same ruler.
