What are common causes for internet connection errors in a testing environment?

Choosing access points and internet speed as a common cause for internet connection errors in a testing environment is appropriate because these factors directly affect the availability and reliability of internet connectivity. Access points are the devices that facilitate wireless connections, and if they are improperly configured or overloaded with too many users, they can lead to slow or intermittent connections. Similarly, internet speed is crucial; limited bandwidth can result in lag or lost connections during important testing situations, impacting the overall user experience. Ensuring that the access points are correctly positioned and that adequate internet speed is available is essential for a smooth testing process, allowing participants to focus on their assessments without the distraction of connectivity issues.
