Felicia's Wi-Fi connection to her phone is extremely slow. However, her

computer that is wired directly to the modem works really well. Which device
do you think might be causing the problem and why?

Based on the information provided, it is likely that the issue lies with the Wi-Fi connection or the phone itself.

Since Felicia's computer, which is wired directly to the modem, works well, it suggests that the modem is functioning properly. Therefore, the problem is unlikely to be caused by the modem.

One possibility is that there could be interference or an obstruction affecting the Wi-Fi signal. This could include physical barriers like walls or distance from the Wi-Fi router. Another possibility is that there might be an issue with the phone's Wi-Fi antenna or its software configuration.

To troubleshoot the issue, Felicia can try the following steps:

1. Move closer to the Wi-Fi router or ensure there are no physical obstructions blocking the signal.
2. Restart the phone and see if the Wi-Fi connection improves.
3. Check if other devices have a similar issue connecting to the Wi-Fi network. If other devices also experience slow speeds, it might indicate a problem with the Wi-Fi router or the internet service provider.
4. Resetting the Wi-Fi router or contacting the internet service provider for assistance might be necessary if the issue persists.

Based on the given information, it is likely that the Wi-Fi router is causing the slow connection to Felicia's phone. This can be inferred because her computer, which is directly connected to the modem, is working well.

Possible reasons for the Wi-Fi connection being slow can include interference, distance from the router, or the router itself may be outdated or experiencing technical issues.
