What will you do when you can't connect to the internet provided by an ISP(Internet Service Provider)

This is the problem most of us face today. I will show you how to troubleshoot that problem. First, you have to check your connections(LAN cables if they are properly inserted and tightly properly).LAN stands for Local Area Network which connects computers and devices in a limited geographical area such as a home,school,office building or closely positioned group of buildings. So if for example you can't connect or browse the internet, you have to check the LAN connected to the system(Desktop,Laptop) and plug it to its appropriate port. Then make sure the green indicator(led bulb) is displaying. In Networking we use what we call the CAT cable( category). we have different categories namely: Cat 3, Cat 5,Cat 5e,Cat6, cat 6e Cat 6a, Cat 7 and beyond. All this CAT cables have different capabilities and functions. The CAT cables is what we use to connect to the laptops,servers, routers. That image above shows the cat cables. We now have to insert it to a connector(RJ-45) ![rj45.jpg]
() Below you will see the cripped RJ-45 connectors with a CAT5 cable. Insert your cable to your network interface card on your system and open your control panel and click network and sharing center. Then select the Ethernet connections which is for LAN(wired connections).
After you have connected your cables properly and its still not browsing through the internet, Then we move over to the next step which is to check the wireless connections and its adapter on the system. Or we can better still called it the wireless LAN while the first is called the wired LAN. In this wireless LAN, we will check the internet configurations(wireless settings). Check and see if the network driver is installed on your system or disabled. You now to run drivers or enable it simply. If after doing all this, its can't browse, then you have to go to the next step and open your command prompt and ping the loopback IP which is (127.0.0.1). I will talk on this terms in the next lessons. ping is important for testing how long it takes data to travel from your computer, go across the various Internet connections and nodes, reach the computer on the other side, and get back to you. If its didn't work, you have to run another command prompt and ping this" ipconfig" or "ipconfig/all" which will display the IP address, default gateway and subnet mask.![ping ip.jpg] () After doing all these things. you can now access your favourite site in the internet.
