Main reasons for disconnections



There are few possibilities for disconnections – lost connectivity between your computer and router/modem (that “blinking lights” gadget on your desk, which ISP gave you to connect you to the net), problems with network provider and then problems in provider's connectivity to the outer net. The reason for loosing connection to router/modem is mainly faulty LAN card, LAN cable or problem in the router/modem. If the router/modem has lost connection to the Internet provider (ISP for short), or the ISP has lost connection to the Internet then you will not be able to browse the web.



Understanding where the problem emanates



You should begin the diagnostics from the end nearest to you in all cases. This is the LAN card of your PC, the cable to the router/modem, and the router/modem itself. The LAN card installed in your computer or laptop has two LED's – amber and green. The amber light blinks when you connect the LAN cable to the router/modem. If it's glowing – the problem is elsewhere. The green LED glows when sending or receiving data over the net, if it glows from time to time – the chances are your LAN card and cable are OK. This leaves the router/modem to check – it is the most common reason for problems in network connectivity. Though you can check every component using software tools, it involves using advanced DOS or command prompt commands and extensive knowledge about networks, so the easiest way to check if the problem is in the router/modem is to restart it – either by plugging it out and back in, or by pressing a little button on the back of the equipment (provided there is one). This resets the router/modem to its original state, and in many cases corrects the connectivity problem. There can be a problem in software settings of the user's computer, but solving this also involves extensive knowledge of computer networks, and should be left to professionals. If the problem is from ISP itself, you should alert the ISP to send technician to check the line.



Simple actions to repair the connection


Restart router/modem, try using new LAN cable between LAN card and router/modem of your PC, if nothing helps, call for assistance from IT experts.
