Your internet speed or packet loss might be the cause. Many technical issues on BigMarker can be caused by slower or unstable internet (network) connections. So before your next webinar, please review the following steps to improve your Internet speed, reduce packet loss and improve your overall experience on BigMarker. **Packet loss** can occur when data packets traveling across a network fail to reach their destination. This can lead to delays, lag, buffering, or dropped connections. There are a couple common causes of packet loss, all of which we've addressed in the list below. **Note:** If you are the webinar admin,  before the start of your event, check that you have chosen the optimal [server location](https://kb.bigmarker.com/knowledge/how-can-i-change-my-servers-location?hsLang=en) within the edit section of the webinar.  1. Ensure you are using a recommended and updated browser (Chrome or Microsoft Edge) and that your system meets our **[System Requirements](https://www.bigmarker.com/system_check).** 2. Restart your browser, computer or router.   3. If possible, plug directly into your internet router with an ethernet connection. Packet lossis inherent in a wireless connection and directly affects your audio and video quality. If plugging into your router isn't an option, move closer to the router or extender. To prevent interference, keep your device and router/extender at least 2 feet apart. 4. Disable wireless devices like speakers, microphones or headphones. These can cause interference. 5. If you have an older router, consider replacing it with a newer model as many connection issues are caused by outdated routers. 6. Close all your browser tabs, windows, and other apps running in the background. Similarly, manually quit Zoom, Loom, Skype, MS Teams, or any other video sharing apps that can "hog" your device's camera and microphone capabilities. 7. Disable **[virtual backgrounds](https://kb.bigmarker.com/knowledge/how-to-set-a-virtual-background?hsLang=en)**. These can use more CPU and network bandwidth. 8. If you are using Screen Sharing to share a presentation, please upload the presentation file instead. Screen sharing will use more bandwidth. 9. Switch Wi-Fi networks if possible (especially if you are on a public or shared network) or ask others to log off. 10. Reduce network activity. Stop streaming music or videos on the same network when using BigMarker. Ask others on your network to do the same. Disconnect any other computers and devices (if possible) that are connected to your network. 11. Disable or remove any browser extensionsthat might be blocking or slowing down your ability to connect. If you have a lot, they will consume CPU. 12. **[Disconnect any VPNs, Firewalls, or anti-virus programs](https://kb.bigmarker.com/knowledge/firewall-or-proxies?hsLang=en).** These may also be browser extensions. 13. Consider disabling **[Graphics Acceleration](https://kb.bigmarker.com/knowledge/enable-disable-hardware-acceleration-in-browser?hsLang=en)** (formerly Hardware Acceleration) within your browser settings. 14. [**Check your system's activity monitor**](https://www.computerhope.com/issues/ch002001.htm), and **[close any unnecessary or unfamiliar applications](https://techstacker.com/how-to-stop-chrome-from-using-all-your-cpu/Lfi7yNPXnTtxAJSzG/)** that are using a lot of CPU (100% or higher) or memory power. You might also need to disconnect external devices that consume a lot CPU when connected to your computer. 15. If you are still having difficulty connecting, try turning off your webcam or screen share and switch to Microphone Audio Only or Dial-in. Audio only uses much less bandwidth. ### **Additional help** If you've tried all the above suggestions and you're still experiencing issues, consider these articles: - [How to Increase Internet Speed](http://www.wikihow.com/Increase-Internet-Speed) - [4 Ways to Speed up a Slow Internet Connection](http://www.wikihow.com/Speed-up-a-Slow-Internet-Connection) - [Solutions for connection issues that might cause packet loss](https://www.lifewire.com/how-to-fix-packet-loss-4176342).
