Not happy with the latency on Starlink? SpaceX CEO Elon Musk says reducing the lag is now a major priority for the satellite internet service. 

Musk tweeted about the latency rates on Tuesday as his company has been shipping a new “Gen 3” Starlink router that can support faster Wi-Fi 6 speeds. 

“We are also super focused on getting latency below 20ms if the user terminal and ground gateway can both be seen by a single satellite,” Musk wrote, before adding that achieving a median latency of under 30 milliseconds is “definitely achievable.”

According to Ookla’s Speedtest data, the median download rate for Starlink across the US is around 60 milliseconds. That’s significantly higher than the 13ms and 30ms that fixed and mobile users can receive, respectively. As a result, the high latency on Starlink can create lag, particularly for online gaming and live video streaming. 

It’s not the first time Musk has promised to bring down the latency for Starlink. In 2021, he also tweeted that the goal was to reduce the latency to 20ms, and that improvements were inbound. “Basically, you should be able to play competitive FPS [first-person shooter] games through Starlink,” he added. 

But since then, the satellite internet system has experienced dramatic growth, surging from a mere 10,000 users to now over 2.2 million—1.3 million of whom reside in the US. The increase has at times strained Starlink’s capacity, resulting in slower speeds. 

In his Tuesday tweet, Musk didn’t elaborate on how SpaceX plans on reducing the latency. But the company is likely trying to expand Starlink’s capacity both by launching more satellites into orbit and by building new ground “gateway” stations.

These ground stations can then beam internet data to the orbiting satellites, which relay the broadband to users on the ground. SpaceX is currently estimated to operate as many as 150 ground stations for Starlink.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
