The most common network problems are:
Duplicate IP addresses: You may get an error message saying the IP address is already in use. The solution is to change the IP address on your system.
IP address exhaustion: In this, you’ll have to adjust the size of the IP address pool in the DHCP settings of your router.
Unable to connect to the internet: The first step is to reset the router and the system. If this doesn’t fix it, it may be a hardware problem or an issue down the line. tracert may help you diagnose where the connection is breaking up.
Low performance: This may be due to network congestion on your end or from your ISP’s end. Depending on the problem, you may have to upgrade your hardware or internet connection.
