Make Your Connection Stronger

If your internet connection is poor, consider the following:

• Try a wired (ethernet) connection. Be aware that you may need an ethernet adapter for your laptop.
• Check your wireless router. Make sure your router is under five years old, uses Wi-Fi Protected Access II (WPA2) security certification and supports both 5GHz and 2.4GHz bands.
• Re-position your device. Move closer to your Wi-Fi router to increase the strength of the wireless signal to your laptop or mobile device.
• Avoid performing large file transfers. Your upload speeds will always be slower than your download speeds. Wait until after class to move large files to and from the cloud or across a network.
• Zoom smart. Virtual backgrounds and HD video are great Zoom features, but they will degrade your bandwidth. Turn them off for a better online experience.
• Be aware of your surroundings. If others on your Wi-Fi network are using streaming services such as Netflix while you're working, it could impact your Zoom experience. Sync up your schedules with those closest to you to avoid connectivity issues.

If adjusting these items still does not improve your experience, contact your Internet Service Provider (ISP).
