Tip 1: Why did the 3G modem often turn off on its own

Owners of 3G modems can face a lot of problems. Some of them are quite easy to solve, and some are not, and one of these problems is due to its spontaneous shutdown.

Why did the 3G modem often turn off by itself

Owners of 3G modems can be indignant overvarious reasons: bad connection of the modem, its spontaneous disconnection, unstable pings, etc. Most often, owners of such devices are faced with a spontaneous disconnection of the modem. If the modem is disconnected, its owner must again get the device out of the socket and connect it back. Naturally, if such a procedure is repeated several times a day, then it can not but upset the person, and such a problem needs to be somehow solved.

Solving the problem of spontaneous shutdown

There are several ways to do this. For example, if your 3G modem is connected via a special extension cable or a hub (usually done to amplify the signal and in order not to break the 3G modem inadvertently), then it simply needs to be disconnected from there and connected to the USB port directly on the computer itself. The problem will be solved. If you do not use a connection through a hub or any similar device, then you need: open the Start menu, go to Control Panel, and then, in the menu on the left, open Device Manager. In the appeared window it is necessary to find the item "Network devices". There must be a variety of COMs directly to the modem itself. They need to be opened and in the power settings remove the checkmark from the point "Allow the device to turn off to save energy." After saving the changes made, the Internet will work properly, without spontaneous shutdown.

Solving other troubles

Of course, spontaneous disconnection of 3G-modem- not the only problem. Very often such devices lose or very much deteriorate signal. In order to get rid of this problem, you just need to put any speakers in close proximity to the 3G modem. In this case, the signal will increase by approximately 30%. In addition, you can not spend money to buy even the cheapest speakers. The owner of the device will need only copper wire. You need to open the cover of the modem and rewrap the device several times in the place where the sim card is located. After that, the end of the wire is set to the place where the signal is best caught. In this way, you can increase the signal to 95%. If the device pings on the device, it can mean only one thing - the device automatically searches for a stable signal. To get rid of this scourge, you need to open a special utility for controlling 3G modem (for example, Megaphone-Internet), select the item "Settings" and "Network". Here you will need to specify the following parameters: "Network Type - WCDMA only", "Band - GSM900 / GSM1800 / WCDMA900 / WCDMA2100", "Registration mode - Manual search". After the update, you need to save the settings and select MegaFon (3G).

Tip 2: Why the usb modem does not work through an extension cable

Owners of USB modems can have many difficulties with this device. One of the most popular is the failure of his work with a special cable.

Connecting a USB modem via a dedicated cable

Surely, owners of USB-modems have heard about the fact,that they can increase the speed of work in the network through a special cable based on a twisted pair or a special hub. Yes, of course, it is. To increase the speed of the USB-modem, it is enough to buy a simple USB extension cable, which is connected to the computer with one end, and the modem itself is installed in the other. Why does this cable increase the speed? It's not that in itself, but in the fact that the user can place the USB-modem in a place where it is possible to catch a good signal, and the user himself will be able to settle in a convenient place.

Possible problems and solutions

Unfortunately, this aspect has a differentside of the coin. Quite often, users who connect their USB-device to the cable experience difficulties while working. This is due to a huge number of different factors. For example, as is known, any cable is an electrical or radio circuit with distributed parameters. Naturally, it also has active linear and wave resistance. The result is that the longer the cable is used by a person to work with a USB modem, the more the signal is distributed directly over the cable. As a result, only a certain part of the signal reaches the user, and not all of the declared potential. This is why you only need to use a high-quality, shielded cable, the length of which will not exceed 3 meters (preferably even less). In addition, a malfunction of the USB modem when working with a cable can occur because the cable itself may be damaged or is broken inside or outside. In order to find out this it is required to look at the entire cable for the presence of various fractures. If outwardly everything looks more or less normal, then, most likely the problem is inside the cable (for example, the cable wires can oxidize or the wires inside it can be broken). You can connect to it another device that has a USB-input and if the computer finds it, then it will be possible to say with certainty that the cable is all right, and the problem lies in the other. If the device still does not appear, then connect the other cable and check the connection on it. If the problem still does not dare, then you should install the USB-modem directly to the computer and check whether the network has appeared. If it is not there, then the problem lies in the device itself and it needs to be changed.
