Common Network Issues And Their Solutions


Suppose you are playing Call of Duty online and suddenly your screen freezes. The game stops working, indicating that there is a problem with your network connection. To be honest, it is the worst feeling ever. Moreover, network issues can create a huge problem if your business runs entirely on the internet. This is a potential disaster. Network problems have to be fixed before you can operate the remote utilities efficiently. If you have a big set up, your IT team can fix the potential issues and all other network problems. However, if you are on your own, you have to deal with the problems yourself.

Many internet providers have dedicated customer service departments to assist network connectivity issues. For example, with TWC internet, you can get instant assistance on call or via live chat, and they will help you troubleshoot your network.

However, if you do not have their internet and want to fix the common network issues yourself, this is the right article for you.

Duplicate IP Address

This problem occurs when two devices share a single IP address at the same time. There is an error indicating that the address is already in use and you can’t access the network. Fortunately, there is a quick fix for this. It usually happens because of your router’s DHCP configuration. This configuration assigns a new IP address to a new device at the beginning of the subnet. Moreover, a second device gets the lower-position address having a static IP. The problem arises when the device that you are using has its own DHCP server. A quick solution to avoid such IP-related issues in the future is by disabling the DHCP server on that device. This will restore the sanity of your network connection. You can prevent this further by simply modifying the configuration on your router.

Wireless Network Not Connecting

If you are running a business, wireless networking is a great way to ensure that everyone has access to the business files while moving about freely. However, a common error occurs when your laptop or smartphone shows full signals from the network but can’t connect to it. If such a problem happens at your home or office,  move closer to the Wi-Fi router and see whether you can connect. If you can, then there is a problem with the network hardware itself. Your network card might receive strong signals but is unable to transmit them effectively. A simple solution to this problem is by updating the network card’s driver. If the problem is solved, well and good. If it isn’t, then you have to replace the network’s hardware entirely.

DNS Problems

DNS problems are a part of common network issues. You get errors like IP Address cannot be found, the network path cannot be found, or DNS does not exist. These are simply, DNS configuration issues. There is no easy way to fix them. You must have a bit of knowledge about the command-line utility. Moreover, all workstations at your home or office can be configured so that they use their DNS servers individually. This will ignore the server assigned by DHCP. Simply check the “Internet Protocol version 4 (TCIP/IP)” settings on your adapter. If your DNS server is incorrectly specified, enable the automate DNS server address.

One Device Unable To Connect To The Network

There can be an instance where a single workstation or device displays a “No Internet” message when you open a browser. By this, we can safely assume that the network is healthy. Therefore, we can turn our attention to any software or hardware in this system. To fix this problem, start with the most basic operation. Change the Ethernet cable, check the network drivers, and make sure that the network adapters are configured. If the problem persists, you can look into the firewall software. Make sure that the ports are open for the external network.

Poor VOIP Quality

VOIP phones are slowly taking over the world. These phones are set to replace traditional phone lines. The delays, distortions, and stutters on your VoIP can create a problem with the network’s productivity. The simplest solution to this problem is by installing a jitter buffer. This acts as a buffer allowing the cached VoIP packets to be accessed during the calls. They can be customized any way you like to meet the requirements of your network. Secondly, you can even buy a playback codec. This eliminates the possibility of packet loss that is a major reason behind poor VoIP quality.

Final Verdict

If your network problems persist, you should call your internet service provider to fix the issue.
