Is Zoom not working and showing the error code 1003? This error code is trying to warn you of specific network issues — here’s what it means and how to fix the problem!
Zoom error code 1003 indicates an issue with your network. To efficiently use the Zoom app, you must have a minimum bandwidth of 2mbps. If your internet connection is too slow, error code 1003 may appear. To improve your internet connectivity move your device closer to the wifi router or try using an ethernet cable.
What is this code, what does it mean — and, most importantly, how can you fix it? Read on to find out.
Why Am I Seeing the Zoom Error Code 1003?
Typically, when a technical issue occurs, an app, software, or program will display an error message. In some cases, an error code may appear instead. Error codes reference specific technical issues—and are unique to each software, app, device, or program.
The error code 404, for example, is a common error code when visiting a website. This code simply means that the website or page cannot be found. Perhaps you typed the link wrong, the publisher removed the page or site, or the site is down? But what about the Zoom error code 1003?
According to Zoom support, the error code 1003 means that your network connection is poor. This issue is related to your internet bandwidth speeds being too slow. Your internet needs to meet certain bandwidth requirements to transmit and receive data over Zoom, specifically video and audio.
How Can I Resolve the Zoom Error Code 1003?
The Zoom support page suggests that you call your network provider (ISP) or Zoom support to get help to fix Zoom error code 1003. Before you do, here are some fixes to try out that both Zoom and your ISP may recommend themselves.
Diagnose Internet Connection Issues Causing the Zoom Error Code 1003
The main reason why you see the Zoom error code 1003 isn’t because of issues with Zoom itself. It’s because of your internet connection. If your internet is down, slow, or experiencing technical difficulties, Zoom won’t display or transmit audio and video properly.
Depending on your type of connection and device, try these steps to diagnose and fix the issue:
- Switch your router or hot spot on and off.
- Disconnect from the Wi-Fi, go to your Wi-Fi settings, forget the network, and connect again.
- On your Windows computer, right-click the internet/Wi-Fi icon in your taskbar. Then, right-click it and choose “Troubleshoot problems.”
- On your Mac, press and hold the option key, click the Wi-Fi status icon, select “Open Wireless Diagnostics,” and then follow the prompts.
- Switching your device off will reset the DNS and other settings, perhaps resolving the connectivity issue.
- Your computer’s diagnostic function should find and suggest repairs for any connectivity issues.
Check Your Internet Speed
The Zoom error code 1003 displays if your internet connection speed doesn’t meet Zoom’s minimum bandwidth requirements. Even if your internet plan speed is sufficient, it still might have fluctuated a few Mbps or Kbps. In so doing, causing Zoom to temporarily not work correctly.
To check how fast your current internet connection speed is:
- Try to load a website or page on your device. If it loads slowly, loads in HTML, or fails to load, your internet speed is probably too slow.
- Use a free internet speed checking software, such as speedtest.net, to check your exact internet speeds.
- Check if your current internet speed meets the minimum requirements for your Zoom call or audio call.
Improve Connectivity & Signal to Fix the Zoom Error Code 1003
A few factors can affect your internet bandwidth and cause the Zoom error code 1003 to display beside your ISP and connectivity issues. Try these steps to ensure your device and your Zoom calls benefit from the best internet connectivity for your setup.
To improve your internet connectivity:
- Ensure your Wi-Fi adapter and router are close together.
- Sit closer to your Wi-Fi router with the device on which you’re using Zoom.
- Hardwire your computer or device to your router using an ethernet cable.
- Move any objects out of the space between your device and router.
- Position your Wi-Fi adapter somewhere where it offers a better signal to your device.
- If using a Wi-Fi repeater/range extender, move it closer to your router/Wi-Fi adapter.
Change Your Zoom Video Settings
Generally, audio calling and screen sharing on Zoom don’t demand very fast internet. However, Zoom video calls, particularly HD video, group calls, and gallery view receiving, do. Are you using Zoom on a slow internet connection, such as mobile data, a hot spot, or public Wi-Fi? Or is your internet just slow at the moment?
If so, you can change your Zoom video call settings to improve functionality:
- Choose to only receive or transmit video, depending on your upload and download speeds.
- In the Zoom Meeting, click the arrow next to “Start Video,” then navigate to Video Settings > Video > and untick HD video.
- Try to limit the Zoom group call participants.
- Call one-to-one if possible.
- Choose not to display any video (or the video thumbnail) while sharing your screen.
- Opt for an audio call instead of a video call.
Upgrade Your Internet Connection if You Still See the Zoom Error Code 1003
Are you still seeing the Zoom error code 1003? If all else fails, it may be time to upgrade your internet connection. So, you can enjoy using Zoom in HD for big group calls or other heavy-duty tasks without limitations.
There are a few ways to upgrade your internet connection:
- Internet type — certain internet connections, such as ADSL, cable, dial-up, mobile data, and satellite internet, are slower than others. For example, fibre, offers the fastest speeds and bandwidth. Ask your ISP about fibre plans (or cable and ADSL if using mobile data).
- Speed — internet speeds vary per internet contract package and price. Ask your internet service provider (ISP) about faster plans and how much they cost.
- Internet provider — if you’re regularly experiencing issues, such as fluctuating speeds and no connectivity, it may be time to find another ISP. Look for an ISP with good coverage in your area using their coverage map.
Technology, such as Zoom, surely has made our lives easier. However, that doesn’t mean it’s bulletproof. With common problems like Zoom showing a black screen and other issues, you might want to just throw in the towel. Luckily, the Zoom error code 1003 is not a serious issue and is easy to fix, too!
