Explanation:

Sub - Question 1

The modem or router could be the issue. If the modem (connects to ISP) or router (distributes Wi - Fi) has a problem with the WAN (Internet) connection, the device can connect to Wi - Fi (local network) but not access the Internet. For example, the modem might not be synced with the ISP, or the router's WAN port/settings are wrong.

The router is likely the problem. The wired computer (connected to modem) works, so the modem and Internet are fine. The slow Wi - Fi on the phone means the router (which provides Wi - Fi) has issues like overloaded Wi - Fi, old Wi - Fi standards, or interference. The wired connection bypasses the router's Wi - Fi part, so it works.

Suggest a guest network. A guest network is a separate Wi - Fi network on the router. It allows guests (AirBnB renters) to connect to Wi - Fi without sharing the main network's password. It can also have restrictions (e.g., no access to local devices) for security.

Answer:

The modem or router could be causing the problem. The computer connects to Wi - Fi (local network) but no Internet means the device (modem/router) connecting to the ISP (Internet) has an issue (e.g., modem not synced, router WAN settings wrong).
