Tips for Troubleshooting Internet Connection Problems

Internet has become as important as the air we breathe today. When we get plagued with a slow Internet connection or other connection problems, we reach the verge of a mental breakdown at times.



If you too have connection problems hampering your connectivity problems, then you have landed on the right page. We will share a few tips for troubleshooting Internet connection problems. These tips will be useful for taking care of some common problems often faced when using Internet.


Troubleshooting Internet Connection in Windows OS


It is often a challenge to troubleshoot Internet connection problems as there can be many possible causes. Before you take up the challenge to solve the problem yourself, try the following steps:

1. If you are using Windows Vista and above, you need to right-click the network icon in the notification area. Click on Diagnose and repair. Those using Windows 8 can follow the same steps and click on Troubleshoot Problems.



2. Next, the computer will try and diagnose the problem. If the problem is found, it will solve it and you overcome your connectivity issues.

Other Ways to Solve Internet Connection Problems


If the above solution does not solve the problem, don’t worry. You can try the following tips to help you get back online. But first you take up all the trouble, check if your router is properly connected and the modem’s power cable or Ethernet cable are not accidently pulled out of the socket?

1. Signal Interference


Many times it so happens, Internet connection becomes slow when the wireless connections face interference. This interference may include signals from cordless phones or other household appliances. Not just your home, but even the appliances from your neighbor’s home may interfere with your wireless signals. At times, a router tucked way behind books or behind the metallic case of your CPU may also lead to low signal strength leading to poor network connectivity. Thus, reposition your router or change the Wi-Fi channel number and get better connectivity.

2. Background Applications Draining Your Connections


Do you use applications or programs such as Peer to Peer (P2P)? Are you into heavy download or online gaming? These applications may continue to run in the background and sucking the life out of your Internet connection. Thus, making it too slow or irresponsive. Check out for such background applications and troubleshoot Internet connection problems.



3. Ping Your Connection


If you find your connection is not working properly, then you can try the ping command. Just open the Command Prompt window from the Start Menu. Here, type in a command like ping google.com. The command will send different packets to the address you have specified. If all is fine, you will find there will be 0% packet loss and time taken for each packet will be fairly less.
In case of loss of packets, it indicated network problems. This means either there is problem with the website (quite rare), your Internet service provider or a problem with your router.

4. A Virus Takes Over Your Computer


Internet worm is a malicious software program. It can spread through computer networks and run havoc in the lives of those who cannot stay offline even for a minute. If your computer gets affected by an Internet worm, it may start connecting randomly and generating network traffic without your knowledge. This will lead to a slow Internet connection and a worried you. Just run a good antivirus software and remove any malicious worms from your computers.

5. Router Trouble


Do you see lights flashing on your router? Is any light missing or blinking uncontrollably? You need to switch off the power source and unplug your router and then the modem. Now, count 1 to 10. Plug it back the modem and then the router. Allow them to get some peaceful time to boot up and then see the activity lights. Try connection your computer with Internet again.

If all the lights are on and still you cannot connect to the Internet or get a response of the ping, now you need to take some serious action. Just pick the cable provided by your ISP and connect it directly to your device or modem. Can you get online now? If no, then call your ISP immediately for answers.

Those who can connect to the Internet directly after bypassing the router, have problems with their router. Most ISP won’t offer tech help related to router they have not helped install. So, grab your router’s handy guide and try troubleshooting your router.

These are a few tips for troubleshooting Internet connection problems. In most cases, rebooting the router and modem tends to solve the connectivity issues. If nothing works, you need to call your tech guy to help you out with your Internet connection problems.

How to Connect Two Computers Without a Router

You may have multiple computers at your home or workplace. In order to connect different computers to share files, documents or Internet connection, you may need to set up a network.


Instead of going through an elaborate process of getting a router, you can do it the easy way. We will show you an easy method that teaches you how to connect two computers without router.


Connecting Computers Without Using a Router


Sharing files, photos, videos, music as well as Internet between two computers is possible without a router. The best and the simplest way is to buy an Ethernet cable and you are good to go.



In order to use an Ethernet crossover cable, your computers need to be installed with LAN or Ethernet cards. If you are using the latest computers then you need not worry. These machines have network cards installed by default. In case your machine does not have it, then do not worry. Just attach an internal LAN card to the motherboard or get yourself a USB Network adapter.

Getting Computers in the Same Workgroup


Now, before you get two computers connected with the help of an Ethernet crossover cable, you need to make sure the computers are in the same workgroup.

Those using Windows XP need to go to My Computer and select the Properties from the drop-down menu. Go to Computer Name in System Properties. Click on the Change button, enter the unique Workgroup name, and restart the computer.

Windows Vista or 7 users need to go to Control Panel and search for Workgroup. Select any entry that says ‘Change Workgroup Name’ and click on the Change button. Type the name you want for your workgroup, save and restart the computer.



Connecting Workgroup Computers Using Ethernet Crossover Cable


Using an Ethernet crossover cable, you need to connect the two computers. Just plug one end of the cable to the network adapter of one computer and the other end to the adapter of Computer B.

You may have to Turn On Network Discovery and File Sharing on your computer. This will help you look for the second computer on your Network. Make sure you select ‘No, make the network I am connected to a private network’ when prompted.

That’s it. Once the computers are connected, you can start sharing files, photos, media, etc. between the two.

Sharing Internet without a Router


When you wish to share Internet between computers who do not belong to the same workgroup, you can do so with an Ethernet cable. All you need is one computer with an active Internet connection and one Ethernet crossover cable.

Those using Windows XP need to go to ‘Network and Internet Connection’ and click on the Network Connections.

When you right-click on the network connection you need to share, select Properties and go to the Advanced tab. Select the Allow network users to connect through this computer’s Internet connection. Click on OK and that’s it. Your computers will now share Internet connection using an Ethernet cable.

Windows Vista and 7 users need to follow a slightly different process. Go to Network Connections in Control Panel and search for View Network Connections. You need to right-click on the network connection you want to share and go to Properties. Now, select Sharing and select ‘Allow other network users to connect through this computer’s Internet connection.’ Once you hit OK, your computers will start sharing the Internet connection.

As you can see, it is possible to connect two computers without Router. Just invest in a good Ethernet crossover cable and you will be good to go!

What is Bluetooth Technology? How Does It Work?

You may have heard youngsters talk about transferring data over Bluetooth. Or may have seen people converse animatedly on the subway.



Actually, they are speaking to someone on the phone using Bluetooth headphones. This makes many wonder what is Bluetooth technology and how does it work.


Let us uncover the truth behind Bluetooth and know more about this useful technology.

Bluetooth Technology – Overview


Bluetooth is a type of wireless technology that helps in transferring data between different Bluetooth-enabled electronic devices. It does not use any wires or cables to connect phones or computers. Instead, it uses radio waves to transfer data and connect devices.



With the help of a tiny computer chip that contains Bluetooth radio or software, it helps connect phones, computers, headphones, watches, etc. Thus, the term hands-free became a fad among the youngsters who wished to do more wirelessly.

Bluetooth is a strange name for a transformative wireless connectivity technology. It is named after Harald Bluetooth, who was a Danish King. He helped in bringing together Scandinavians of the 10th century. Bluetooth in ways helps different devices connect wirelessly.

How Does Bluetooth Work?


It is not magic that helps Bluetooth work. Radio-wave technology helps Bluetooth function. It helps devices over short distances connect each other between 10m or 30/40 feet. Bluetooth devices with a range of over 100 feet are also available.



The Bluetooth RF transceiver operates within the unlicensed ISM band centered at 2.4GHz. Using an RF topology called the ‘star topology’, it manages devices. When devices are synchronized, it leads to the creation of one expert and other servant type connection. The expert device or master will communicate with the slave devices within the Bluetooth system. It will deliver its own exclusive address and the value of its inner time.

When the master device sends data or communicates, the slave devices will receive the information. For example, when you switch on the Bluetooth on your mobile phone and connect it to the Bluetooth speakers. First, your phone will search for devices in your nearby areas and then display your speakers. Choose your speakers to connect the devices. Once the connection is established, you can start playing music on your phone using the speakers.

This was all about what is Bluetooth technology and how does it work. The technical details are not much use to a general user. All you need to know is connecting different devices together and using them for hands-free speaking or listening to high-quality stereo music or using your smartwatch.
