Weak Wi-Fi is common in dense apartment areas.

• Move closer to router or access point.
• Avoid metal/brick obstacles between router and computer.
• Change router position to higher shelf and open space.
• Use a Wi-Fi analyzer app to pick the least crowded channel (2.4GHz: 1,6,11).
• If available, switch to 5GHz band for less interference.

After changes, reconnect and verify speed via speedtest.net.
