Your movie loads, then stalls. The spinning wheel comes back every few minutes, the picture drops to a blurry low-resolution version, or playback freezes outright. Whatever the symptom, Prime Video buffering almost always comes down to bandwidth, a stale app or browser, or a network setting quietly getting in the way.
The good news: most of these fixes take under a minute, and the quickest ones resolve the majority of cases. Work through the sections below in order, from fastest and most common to the more specialized fixes for desktop browsers and external displays.
One thing to rule out first. Error codes 2063 and 5004 can appear during playback but are not buffering problems: 2063 points to your payment details and 5004 to your login credentials. If you see those, fix the account, not the network.
Pause Other Internet Activity
Prime Video serves the highest quality your connection can handle in the moment, so anything else competing for bandwidth can trigger buffering. This is the single most common cause and the easiest to test.
Pause downloads, uploads, and other streams running on the same network, especially on other devices. The official minimums are 1 Mb/s for SD and 5 Mb/s for HD, but those are floors, not targets. A connection sitting right at the minimum can still stall the moment something else demands bandwidth.
Restart the App and Your Device
Close the Prime Video app (or your web browser if you are watching on a computer), then restart the device itself. This clears the temporary state behind many short-lived playback hiccups.
On a Fire TV or Fire TV Stick, the in-software restart lives at Settings > My Fire TV > Restart. On other connected devices, a full power cycle does the same job.
Restart Your Router and Modem
A weak Wi-Fi signal, a router that has been running for weeks, or a device that has quietly dropped off the network can all show up as buffering. Restarting your home network hardware clears a surprising number of stubborn cases.
- 1.Confirm your device is actually connected to the internet (check its Settings menu).
- 2.For Wi-Fi, verify you entered the correct network password.
- 3.Restart your connected device along with your modem and router.
- 4.Confirm the device firmware or operating system is up to date.
If buffering persists on Wi-Fi, connect the streaming device directly to your router with an Ethernet cable. A wired connection sidesteps signal and interference problems entirely.
Update the App, Browser, or Device
An out-of-date app, browser, operating system, or firmware is a frequent and easily missed cause. Make sure everything in the chain has the latest updates.
On a Fire TV or Fire TV Stick, go to Settings > My Fire TV > About > Check for System Update. On a Fire Tablet, open Settings > Device Options > System Updates > Updates: Check Now.
In Chrome, type chrome://settings/help in the address bar, or open the menu, select Help, then About Google Chrome, and relaunch after it updates. In Firefox, open the menu, select Help, then About Firefox, and restart once the update downloads.
Lower the Streaming Quality
If your connection simply cannot sustain a higher resolution, dialing the quality down trades sharpness for a stable, stall-free picture. Where you find this control depends on the surface.
In the mobile app (Android or iOS), tap the My Stuff icon at the bottom right, tap the gear/Settings icon at the top right, then open Stream & Download.
- 1.Select Streaming Quality.
- 2.Choose a lower tier: Best, Better, Good, or Data Saver.
- 3.Data Saver uses the least bandwidth of the four.
- 4.You can adjust Download Quality in the same section using the same tiers.
On the desktop web player at primevideo.com, or on Xbox and PlayStation, start a title, click the gear icon at the top right of the player, and pick Good, Better, or Best. The web and console players do not offer a Data Saver tier, and that picker shows no resolution numbers. Note that some smart-TV platforms auto-adjust to your bandwidth and provide no manual quality control at all.
Check How Many Devices Are Streaming
Prime Video allows the same title on only two devices at a time. If playback keeps interrupting, confirm someone else is not watching the same thing elsewhere on your account.
Turn Off Any VPN or Proxy
A VPN or proxy server can interfere with playback and surface as buffering or errors. Deactivate any VPN or proxy on the device and try again.
Update Your DNS Settings
If you can reach the internet fine on other devices but Prime Video still struggles, the connected device's DNS configuration may be the culprit. Update the DNS settings on that device and retry playback.
Clear the Prime Video App Cache
A corrupted or bloated app cache can degrade playback over time. On Fire TV, clearing the cache is safe and does not log you out.
- 1.Open Settings from the Fire TV menu.
- 2.Select Applications.
- 3.Select Manage Installed Applications.
- 4.Select the Prime Video app.
- 5.Select Clear Cache.
If problems continue, you can select Clear Data to fully reset the app, but be aware this signs you out and requires logging back in on next launch. Newer Fire TV software also offers an option under Settings > Applications > Manage Installed Applications to clear every app's cache at once. On a phone, the equivalent quick reset is to force stop the app: open your Android Settings, find the Prime Video app, and select Force Stop, or on iPhone and iPad, swipe up to the app switcher and swipe the Prime Video preview away.
Fix Browser Content Protection on Desktop (Error 7235)
On a computer, Prime Video relies on a content-protection module in your browser. An outdated Widevine component or disabled protected-content settings in Chrome can break or stall playback, often shown as Error 7235.
- 1.Confirm Chrome is fully up to date (menu > About Chrome).
- 2.Enter chrome://components in the address bar and select Check for Update under Widevine Content Decryption Module.
- 3.Open the Chrome menu, then Settings > Security and privacy > Site settings.
- 4.Select Additional content settings, then Protected content IDs.
- 5.Ensure both "Sites can play protected content" and "Sites can use identifiers" are enabled, then restart Chrome.
Keep in mind that 4K Ultra HD is not supported in any desktop browser, so browser playback tops out below 4K regardless of your connection.
Resolve HDMI and Display Issues (Error 7279)
On external streaming devices, playback uses copy protection over HDMI. The cable must support HDCP 1.4 for HD or HDCP 2.2 for UHD and HDR content. A mismatched or aging cable, or an unused secondary display, can block protected playback and produce Error 7279, which is a display problem, not a network one.
- 1.Ensure your web browser (if applicable) has the latest updates.
- 2.Update your drivers, including your graphics card drivers.
- 3.Try connecting your monitor or TV using a different cable.
- 4.Disconnect any secondary displays that are not in use.
Turn Off TV Motion Smoothing
Sometimes the stream is fine and your TV is the problem. Motion-smoothing features add judder or excessive motion blur that is easy to mistake for buffering.
Open your TV's picture or settings menu and turn the Motion setting to Off. The feature has a different name on each brand: Auto Motion Plus on Samsung, TruMotion on LG, MotionFlow on Sony, and CineMotion or Motion Picture on others.
Frequently Asked Questions
What internet speed do I need for Prime Video?
The official minimums are 1 Mb/s for SD and 5 Mb/s for HD. These are floors, not recommendations, and Prime Video always serves the highest quality your available bandwidth allows, so a connection sitting at the minimum can still buffer whenever something else uses the network.
Will clearing the cache on Fire TV log me out?
No. Clearing the cache leaves you signed in. Only Clear Data resets the app fully and forces you to sign in again on the next launch, so reach for Clear Cache first.
Why does Prime Video buffer in 4K but not in HD?
4K needs far more sustained bandwidth than HD, so a connection that handles HD comfortably can still stall at 4K. Note that 4K is not available in desktop web browsers at all, so 4K buffering only applies to supported TVs and streaming devices.
I got Error 2063 or 5004 while watching. Is that a buffering problem?
No. Despite appearing during playback, 2063 relates to your payment details and 5004 to your login credentials. Update the relevant account information rather than troubleshooting your network.
Can too many people streaming cause buffering?
Yes, in two ways. Prime Video permits the same title on only two devices at once, and any other devices using your home network at the same time eat into the bandwidth your stream needs. Pause other activity and confirm no one else is watching the same title.
Where do I change the streaming quality?
In the mobile app, tap My Stuff, then the gear icon, then Stream & Download > Streaming Quality, and pick down to Data Saver. On the desktop web player or a console, start a title and click the gear icon in the player to choose Good, Better, or Best. Many smart TVs auto-adjust quality and offer no manual control.
