Advice 1: Why 3G modem started to disconnect itself

The owners of the 3G modems can encounter a huge variety of problems. Some of them can be solved quite simply, and some don't, and one connected with his spontaneous trip.
Why 3G modem started to disconnect itself
The owners of the 3G modems can resent for various reasons: a bad connection of the modem, it is inadvertent disconnection, unstable pings, etc. most Often, the owners of such devices are faced with spontaneous disabling of the modem. So if the modem is disabled, its owner has to again get the device from the connector and plug it back in. Of course, if this procedure is repeated several times a day, it can not to upset the person, and this problem needs to be solved somehow.

The solution to the problem with spontaneous disabling

There are several ways to do it. For example, if your 3G modem is connected via a special extension cable or hub (this is usually done to enhance the signal and in order not to break accidentally 3G modem), it's just you want to disable from there and attach to a USB port directly on the computer. The problem will be solved. If you use a connection via a hub or some such device, then you'll need to open "start menu", go to "control Panel", and then, in the left menu, open the "device Manager". In the window that appears you should find "Network device". There should be a variety of Catfish the modem. They need to be open and in the power settings remove the tick from "Allow disable device to save energy". After saving the changes, the Internet will work properly, without inadvertent disconnection.

Solution other troubles

Of course, spontaneous disabling 3G is not the only problem. Very often these devices are lost or greatly deteriorating the signal. In order to get rid of this problem, you just need to put any speakers in the vicinity with 3G modem. In this case, the signal will increase by approximately 30%. In addition, you can not spend the money to buy even the cheapest speakers.

The device owner will need only to copper wire. You need to open the lid of the modem and several times to wrap the wire device in the place where is the SIM card. Then the end of the wire is set to the place where he can receive the signal. Thus it is possible to increase the signal to 95%. If your ping jumps, then it can only mean one thing - the device automatically searches for a stable signal.

To get rid of this scourge, you need to open a special tool to control 3G modem (for example, MegaFon-Internet), select "Settings" and "Network". Here you need to specify the following parameters: Network Type - WCDMA only", "Band - GSM900/GSM1800/WCDMA900/WCDMA2100", "registration Mode - Manual search. After the updates you want to save the settings and choose MegaFon (3G).

Connecting the USB modem via a special cable

Probably the owners of USB modems heard that they can increase the speed of the network through a special cable based on twisted pair or a special hub. Yes, of course. To speed up a USB modem is enough to buy a simple USB extension cable that one end connects to the computer and the other is set directly in the modem itself. Why this cable increases the speed? The matter is not that in itself, but the fact that the user can place the USB modem in the place where you can catch a good signal, and the user can be located at a convenient location.

Possible problems and their solution

Unfortunately, this aspect there is another side of the coin. Quite often users that connect your USB device cable to experience difficulties at work. This is due to the huge number of different factors. For example, as you know, any cable is an electrical or electronic circuit with distributed parameters. Of course, he also has and active linear and wave resistance. The result is that the longer the cable uses a person to work with a USB modem, the more the signal will be distributed directly by cable. As a result, until the user reaches only a certain part of the signal, not the entire potential. That's why you want to use only high quality shielded cables, whose length does not exceed 3 meters (preferably even less).

In addition, a problem with the USB modem when working with the cable can occur due to the fact that the cable itself may be damaged or broken inside or outside. In order to determine that you want to watch all the cable for different fractures. If externally it looks more or less normal, then, most likely the problem is inside the cable (e.g., cable wire can be oxidized or wire inside it may be broken). You can connect another device with USB input and if the computer will find it, then we can safely say that with the cable all right, but the problem lies elsewhere. If the device still does not appear, then connect the other cable and check the connection on it. If the problem is still not resolved, then you should install the USB modem directly to the computer and check to see if a network. If not, then the problem is in the device and it needs to change.
