Adjust your WiFi channel:
When you live in an apartment, you may have this problem because you choose the busy channel when using the wifi facility. When more than one person uses the WiFi feature on the same channel, the internet speed will slow down. So, check the router on your smartphone or computer. Switch to a channel with very few users.
Choose the best frequency:
Most routers will offer two frequencies. I.e., 2.4 GHZ and 5 GHZ. Generally, a 2.4 GHz connection will have lower internet speeds and stronger signal strength. You can connect through this when you are far away.
At the same time, 5 GHz will be weak at the signal level. But, internet speed is more available. Also, check that separate network connections are made on your router to deliver 2.4 GHZ and 5 GHZ signals.
Place the router in the correct position:
Only if your router is in the right place will the signal be received properly. So, make sure it is in the right place. Do not place the router near TVs, Bluetooth speakers, baby monitors, gaming devices, or kitchen appliances that could cause electronic interference.
Placing it 5 feet above ground level would be the best solution. You can keep this in the center of the house. In addition, it can be connected to another phone line at home.
