Solving network problems is a frequent task for IT departments. While there are many possible network problems, problems commonly arise from these causes:
1. Configuration problems
There are multiple places where misconfigurations can lead to network problems. These include IP addresses that are assigned incorrectly, firewall rules that block valid data, and pointing to the incorrect DNS server.
2. Hardware problems
Hardware problems can arise in any of the devices involved in networks, including bad network cards in users’ computers, bad routers, and damaged cables. These problems can be as simple to fix as tightening a loose cable or require replacing the whole device.
3. Overload problems
Overloaded networks greatly degrade the user experience. Buying a bigger pipe can help, but so can solutions such as blocking user access to bandwidth-intensive sites that aren’t required for business, such as video streaming services.
4. Network design problems
Bad network design can lead to both performance problems and security problems. Sometimes the problem is that the network wasn’t designed to provide the type of service being used, such as VoIP. Even a good network design that’s badly documented can make network support harder than it needs to be.
5. Security problems
Problems can be the result of malware or a targeted attack on your systems. Appropriate security tools can help block malware and detect attacks before they’re able to damage your systems.
6. Application problems
Poor application design can contribute to network overload.
7. Shadow IT
Although shadow IT is often used to describe unauthorized usage of cloud services, there can also be unauthorized use of applications and other technology resources on premises, and these can put excess load on network. Be on the lookout for unapproved applications as well as internet of things devices.
Many network problems can be diagnosed through real-time monitoring that shows where slowdowns are occurring. Applying policies to users and groups will help ensure the existing network capacity is properly used. Sometimes the best solution is upgrading the network to higher speed or higher capacity components, along with redesigning subnetworks to improve traffic flows.
