What should a technician check first if a customer reports slow internet speed?

When a customer reports slow internet speed, checking the modem settings is crucial because the modem is a key device that connects a customer's network to the internet. Incorrect settings in the modem, such as outdated firmware, improper configurations, or issues with the connection between the modem and the service provider, can significantly affect internet speed.

Ensuring that the modem is configured properly and functioning as intended can often resolve issues related to slow internet. Technicians often start here because modem settings can directly impact performance.

Other options, while important, may not directly address the speed issue as effectively initially. The customer's location may affect connectivity, but it's essential to ascertain if the modem is properly configured before considering external factors. Similarly, checking the internet service provider's status is important, but if the modem is not configured correctly, the results could still be misleading. The age of the equipment can matter, but it is more prudent to first examine the settings that could be causing immediate performance issues.
