Speedify Fixes Slow Upload Speeds on Starlink
Starlink upload speed is much lower than download speed. Starlink says most users get download speeds over 100 Mbps, but upload speeds between 10 and 30 Mbps. When uploads stall on top of that, the cause is usually a blocked view of the sky, a busy Starlink network in the evening, bad weather, or Wi-Fi inside your home.
Starlink Internet Connection Drops Happen to Everyone
Speedify measures thousands of Starlink users in more than 140 countries. In September 2026, fixed Starlink dishes went offline for about 38 minutes a day on average, and Starlink dishes on RVs and boats for about 46 minutes a day.
All Starlink dishes also see short dropouts roughly every 15 seconds as the Starlink internet connection switches from one moving satellite to the next. Even a perfectly installed Starlink dish goes offline, and about 7 in 10 Starlink users on Speedify use Starlink together with a second internet connection, like 4G/5G cellular.

Why Starlink Upload Speed Is Slower Than Download Speed
Starlink gives downloads more room than uploads. Like most cable internet, Starlink sets aside more capacity for data coming to you than for data you send.
Your Starlink dish switches satellites about every 15 seconds. Each switch can pause an upload for a moment, which hurts long uploads like video calls, live streams and cloud backups the most.
Busy evenings slow uploads further. When many people near you use Starlink at the same time, everyone’s speed drops, and uploads had less room to begin with.
Bad weather slows uploads too. Heavy rain and storms weaken the signal between your Starlink dish and the satellites, in both directions.
How to Fix Slow Starlink Upload Speeds
Step 1: Test Your Starlink Upload Speed at Different Times of Day. Run a speed test in the Starlink app in the early morning, at midday, and in the evening, and compare the upload numbers. If uploads are only slow in the evening, the Starlink network in your area is busy, and the last section shows how to keep uploads moving.
Step 2: Clear Obstructions Blocking Your Starlink Dish’s View of the Sky. Make sure nothing blocks the Starlink dish’s view of the sky in any direction. Even small obstructions slow uploads down. Use Check for Obstructions in the Starlink app to find what’s in the way.
Step 3: Update the Software on Your Starlink Dish. Starlink releases software updates that improve speed. Check the software version in the Starlink app and let updates install automatically.
Step 4: Connect Your Computer to the Starlink Router with an Ethernet Cable. Wi-Fi adds delay and can slow uploads further. A cable avoids that.
Step 5: Put Uploads First in Your Own Router’s Settings (If You Use One). If you use your own router, its Quality of Service (QoS) setting can put video calls and cloud backups ahead of everything else.
Get Faster Starlink Uploads with Speedify
Some slow uploads, like a busy Starlink network in the evening or the moment your Starlink dish switches satellites, aren’t something you can fix at home. For those, add a second internet connection.
Speedify combines your Starlink internet connection with another Starlink dish, 4G/5G cellular, DSL or cable, and uses them at the same time, so your uploads can use the upload speed of both. Speedify needs that second internet connection: with Starlink alone, it can’t add upload speed.
- When your Starlink dish switches satellites, Speedify keeps your upload going on the other internet connection.
- Video calls, cloud backups and live streams keep going when one internet connection has a problem.
To set it up, see how to combine Starlink with 4G/5G cellular on a Windows PC, or how to set up Starlink and Speedify on a Mac.
Speedify finds your internet connections and sets itself up. To save cellular data, set Starlink as your main internet connection and your other internet connections as secondary, so Speedify uses them only when Starlink needs help. For the most upload speed, leave every internet connection on Always.
Slow Starlink uploads don’t have to hold back your video calls, live streams or backups. Speedify uses every internet connection you have, so your uploads keep moving when Starlink slows down.
