Wi-Fi problems can occur when your router has a weak signal or is too far from your device. This can lead to slow internet speeds or dropped connections. Interference from other electronic devices, such as microwaves or cordless phones, can also disrupt the Wi-Fi signal. Another common issue is network congestion, which happens when too many devices are connected to the same network. This can slow down the internet for everyone. Regularly updating your router firmware and ensuring proper placement can help improve your Wi-Fi performance.
