[Solve] HOW TO: Fix Most Common Problem With Network Connection

Have you ever experienced minor problem with your network connection? Does your PC/NETBOOK/LAPTOP can't connect to modem? What are the causes of these network connection problems? How will you solve with this kind of problem?

This is the most common problem encountered in a company. At least one system could not connect with the network. Probably, the most common cause of it is the modem issues.

Actually, both client and server sides have the issues for the failure to connect in a network. While looking for answers in the internet, you could try these simple troubleshooting options to fix the problem. Today, I will share most of my encountered experience here. Well, I did fix those too. (^_^)

Most Common Issues Failure to Connect
  • Your system unit does not load drivers(network driver) properly
  • The service of the connection has been disabled
  • Modem cannot accommodate more unit to connect
  • Wire problem(might slightly slipped)
  • Signal Problem(WI-FI)
  • DHCP server might be down
How to Troubleshoot Network Connection

Solution #1
First, the simplest and most basic step is to unplug your LAN wire and then plug again. If it does not work, try next solution.

Solution  #2
If you still cant connect to the network, try to restart your adapter. To enable/disable it.

1. Go to Control Panel
2. Look for Network and Internet
3. Then, click Network and Sharing Center

Tip: In the explorer, simple paste this Control Panel\Network and Internet\Network and Sharing Center and hit enter.

4. In the left pane, choose Change Adapter Setting
5. You will see more Connections here. Depending on what connection you are in. Example if you are directly connected to LAN then choose LAN. However, if you use other connection type like Modems or WIFI settings choose it specifically.

I would have guessed you use LAN option. With LAN option, it has the same procedure with other type.
Simply right-click that Connection icon, then disable(disconnect) and enable(connect) again. This will reset the acquiring of IP address in your Modem (If set to DHCP, it will automatically set IP address).

Does it solve the problem if it is not, then proceed the next solution.

Solution #3

Works for both Laptop(connects tru WIFI signal) and PC. If the solution #2 does not fix it, you can manually set your ip address.

1. In the Connections (see above steps), then right click the icon and choose properties. It will displays Local Area Connections Properties, find Internet Protoco Versionl 4(TCP/IP v4). It is mostly used protocol though.
2. Then choose IPv4 then click Properties
3. Normally, it is set to automatically obtain IP address and DNS servers. 

Additional info: Why do we have to set it manually? If the modem has DHCP issues, manual setting up the IP address could help solve the connection problem.

4. Then set use the following address and DNS Servers

If you know your network IP, this is quite simple. However, in most cases, it used private IP. To set manually:

IP address:*
Subnet Mask:
Default Gateway:**

*If your network belongs in the range of Class C IP network. It ranges to 2-254 and you can choose between it.
** Most network administrator recommends to use 1 to be the default gateway. But if your company has a different number, use it instead.

Solution #4

If previous solution does not meet the solution, you can just RESET your MODEM. Works most at the time. However, if it is not working. Contact IT administrator or direct to your Internet  Service Provider! :_)
