What can be made 3G modem. Do not use external antennas

The device, externally similar to the usual USB flash drive, is so convenient and mobile that the unprepared user can cause a lot of questions about how to work with it where to connect and how to configure it.

It is difficult to believe that in such a small device, the possibilities of high-speed connection to the global network are linked. However, in order to use these features, you need to carefully examine the instructions and perform a number of certain actions, the first of which is the insertion of the SIM card.

Before use, open the modem housing (depending on the model, the ways to open the enclosures may vary), then gently insert a SIM card acquired from the cellular operator into it. Recently, the SIM card is sold complete with modems, but they can be purchased separately. These are not ordinary cards from the phone, they are created specifically for modems. Please note that the card is inserted down by contacts, as in conventional phones. Close the case.

Connecting a modem to a computer

In order to connect a modem to a computer, you must remove the side cap, and then you will see a USB output. Insert the modem into any USB connector of your computer, ensuring that it is fully entered into the connection. As soon as the computer define your device, a message will automatically appear that the system has found new equipment. Do not press anything, the setting will start automatically. During installation, instructions and prompts will appear, which must be followed until the device is fully installed.

If you are all done correctly, but the installation has not started, try to reconnect your modem. If the computer does not define it again, go to the "Control Panel", in the "Install New Equipment" tab. If the second path does not lead you to the installation, contact the store in which you bought a modem - it can be faulty.

Beginning of work

As soon as it is complete, you will see that the label of the relevant program appeared on the desktop. Click on it with a mouse in order to manage your tariff, go to the global network, connect and disable the modem. There you can see the balance of funds and the rest of the unused traffic. If you have already spent all paid traffic, you can easily replenish the account through ordinary terminals or ATMs.

If you want to disable a 3G modem, you should not pull it out of the computer sharply so that the settings and the device did not suffer. Use the safe removal function and be sure to close the Internet connection program before exit.

We work with a 3G modem Huawei E352 more comfortable

  • Lumber room *

I have a need for a wireless Internet on my laptop, and I purchased a USB modem Huawei E352 from MegaFon. The modem copes with its tasks to this day. But at the first acquaintance with the modem, I found several inconveniences, which I decided to fix and make work with a modem more enjoyable.
So what did I want? In Windows 7 there is a great opportunity to establish a connection with the Internet in three clicks. To do this, you need to click on the network icon, select the desired network (especially convenient, if it is Wi-Fi), and click "Connect" to the third click. From the modem, I wanted the same thing - insert a modem, and in three clicks to connect to the Internet. But it was not there. When the modem is first connected, it defined as a card reader with a missing memory card and as a CD-ROM drive from which the program installer started. Together with the modem drivers, this installer installed the MEGAFON MODEM cumbersome program. Now every time, after I passed the modem in a laptop, this green program was launched long and tediously, from which I needed only one thing - the "Connect" button. In addition, after clicking on the large green button, the "Disable" broke out absolutely all connectivity to the Internet. This state of affairs did not suit me, I wanted to connect to the Internet with standard Windows tools, and not wait for 5 minutes, until this brilliant handicraft can be launched, and I wanted to choose what exactly the connection I want to complete, and not disconnect everything at once, so With the help of Google, patience and direct hands, I achieved that:
1) To connect to the Internet it has become enough to click on the tray icon, select the desired connection and click "Connect".
2) When the modem is connected to the laptop, a slow green program stopped automatically (in the settings of the program itself it is impossible)
3) The modem after connecting to the computer began to be defined as an independent network card, it stopped reading a card reader, a CD and modem in one person.
Instructions, how to achieve such an effect, under the cut.

0. So, the first thing we need is a modem itself and the MEGAFON MODEM installed program. If this is the first modem connection to the computer, then when connected to the tray, the inscription will appear on a short time which COM port modem will use. This information should be remembered, it will be needed in the future. If the modem is used not for the first time, then you can see the port number in the control panel, in the "Phone and Modem" section, provided that the modem is now connected to the computer, and the green program is installed.
1. To begin with, we do so that the Megafon Modem program does not start when the modem is connected. To do this, go to the folder with the installed program, open the Autorun folder and start uninstall.exe. After that, the folder will remain empty, and the program will stop running without your desire.
2. I will transfer the modem from the RAS mode to NDIS mode (this will give us the opportunity to connect to the Internet via the modem as easily as through Wi-Fi), as well as convincing it that it is not a flash drive, not a card reader and not even a CD, but Just only the network device, and also advise it to work only in 3G mode. To do this, you can use any already installed console terminal you usually use, or you can download Putty, if you did not use the terminals earlier. In my opinion, this is a very small and very convenient program.
Next, connect through the terminal to the modem. In the case of Putty, it will be necessary to select "Serial" after starting the program in the "Connection Type" section, and write a port number, for example, "COM11" in the "Serial Line" field.
In the console enter the command:


That's all! Now our modem works in NDIS mode, and the cardrider and CD-ROM features are disabled and the next time you connect the modem, it is already defined as network equipment connected via USB, and nothing superfluous. It is possible that after entering this command, the modem will start to issue Terminal with a frequency of a few seconds service information. Everything is in order, it should be.
In case you need to contact the modem through the terminal, do not pay attention to what the modem writes, and simply enter the necessary command.
Antidote in case you need to reset the default modem settings:
AT ^ setport \u003d "A1, A2; 1,2,3,7, A1, A2,4,5,6, A, B, D, E"

The method described in the article is also suitable for Huawei E367, E392, E353 and E171 modems with Firmware 21.156.00.00.143. I found information about the AT teams on the forum dedicated to modems, cellular communication and everything is connected with this. Also, on the link there are commands to configure Huawei E1750, as well as commands for plotting modes in modems with LTE, for example, E392.

Work faster and how?
Nowadays, the Internet becomes an important component of each person's life. A huge number of people is already working on the Internet. Some are on the Internet business, others communicate with people of all the globe or search for the right information, the third swing movies and music, the fourth meet with interesting people or play games ... Now the Internet is recognized as an integral part of life. Too often, we need to quickly find information about this or that kind, and because of the weak Internet connections we spend your precious time wasted.
There are situations where you need to urgently make important transactions, for example, to acquire shares, and a bad Internet connection can disrupt the operation. In this case, you lose money.

In the conditions of highly developed modern civilization, it is recognized very convenient and practical. You have the opportunity to use the Internet anywhere, download the amount of information you need. If you have a problem with the speed of downloading, which can often be observed in the places of weak taking 3G signals - it is very easy to fix with several uncomplicated actions.
At firstIn order to strengthen the signal, you need the so-called USB extension, a long 2-3 meter. You need to connect using the extension, the modem to take away and preferably higher from the computer, you can closer to the windows and away from the wall. This method will help trouble-freely, so many recommend it to be used primarily.
Secondly, Often the quality of communication may depend not so much on the quality of the 3G modem transceiver devices, and how many of some of the network configuration settings available for all users. For example, for TCP / IP there is a parameter that is called the block size in the package (or MTU). By default, Windows Program This value puts 1500. However, if you try other values, 256 - 4096, then, most likely, at a certain number, the speed will increase in two or four times. The above method is checked by testing, although there are programs that use the automatic MTU selection mode.
Thirdly, a significant improvement in the speed of the Internet connection can be achieved by the establishment of external. In the urban conditions, set by the reinforcing coefficient of up to 5DB, can perfectly cope with the task. But the city requires already directed reinforcement, directed towards the base stations of the operator. Naturally, for this case, you need to stockday 3G modem that has a connector for connecting external antennas. In the absence of your modem of the above-mentioned connector, you can apply the installation of an induction adapter, but it must be remembered that the use of induction adapters should be the loss of power, which is about 30%. This fact dictates its rules to the use of an induction adapter requires the choice of antenna with the reserves of gain coefficients (optimally 40%).
There are more exotic ways to speed up the Internet. Here is one of them- take copper wire, foil and preferably USB cord 3.5 meters. At first, it is necessary to wind up a 3G modem with a wire from copper to the turn to the turn, then we remove the extra ends until you get a pleasant and neat modem in the copper wire, then the foil is overcome this modem on top of the copper wire layer.
After that, it remains to connect the cord to the modem and your laptop or desktop computer and check.
And finally, to avoid problems with speed, you can use programs - "Internet accelerators (modem)". Programs will increase the speed of any Internet connection and allow you to perform certain operations quickly.
The Internet accelerator is called a program that increases the speed of Internet connections, which allows you to transmit the data faster several times. They can also sometimes be called the 3G modems accelerator. The speed of Internet connections increases by optimizing in the operating system settings. These programs are automatically a number of necessary tests, and determine the optimal values \u200b\u200bof the parameters. Internet accelerators or accelerators have a clear and simple interface. Internet accelerators in Light versions can be downloaded on some sites for free. If there is a desire to legally use the full version of 3G modem accelerators, you must purchase this program.
In addition, you do not have to know the concept of MTU to use the program. 3G modem accelerators programs have a simple interface, which makes it possible to use it any person. When working with the program, it will be enough to start the above accelerator and after pressing the "Selection of the optimal MTU value" button, select the MTU number in automatic mode. Then move the slider to the button with the name "quickly" and click "Accelerate the Internet". You can just make a reboot of the computer.
Programs "Internet accelerators" allow you to accelerate the connection to the Internet. Moreover, it does not depend on the methods of connecting to the network and types of devices on the computer. Program technology increase the speed of the data packet download from the Internet (more than 60%). The browser that supports the Internet accelerator must transfer information to a special server that analyzes the requested pages, communication channels and devices from which requests were made. After that, the optimized version of the requested site will quickly be downloaded to the user's browser will quickly be downloaded.

The use of the Internet Accelerator program will give confidence that the Internet connection will never let you down. And most importantly, this program will allow you at any time to get fast and high-quality communication with the Internet.

Here I will describe in detail what household methods are possible to improve stability, speed and ping modem. Consider this on the example of the Mobile Wegaphone Mobile Network Provider and the Huawei E352 modem. Surely everyone came across the problem of poor quality / bad signal. Not always to buy antenna (if the modem has a connector for an external antenna) is a solution to this problem. 3G signal amplifier can be done by itself.

Examples:
1. We buy cheap Chinese speakers, connect them into the outlet and set next to the USB modem - the signal gain at least 30% is guaranteed.
2. Take copper wire than longer, the better, open the modem cover, wind in 5-6 circles in the place where the SIM card is located. Next, throw off the wire in the window. On the end of the wire you can climb a 1 liter beer jar, having preciped the cover with scissors or a knife (as if you did a glass of it). We have the bank of the cropped side where the signal is better caught. In this way, you can enhance the signal to 90-95%.

Further. Surely everyone came across that a USB modem is suddenly arbitrarily disabled (disappears from the system as a device and then it is connected again). The reason for this is the lack of USB power ports of the motherboard. This usually occurs when a USB extension is used to connect a 3G modem. That is, a portion of the power goes into a USB cable, respectively, the device is spontaneously disconnected into the most unexpected moments. Therefore, never connect the 3G modem via USB extension. I sympathize with those who connect to the Internet through mobile phones - after all, they use the USB cable - the stable Internet will not be - constant disconnecting the phone, or in general its reboot.

Surely everyone knows about unstable pings 3G network. They jump from 700 to 1000 and above + to the whole of this modem it happens from the network (not from the fact that there is a lack of USB power, and for a simple reason that I will describe below). Many do not know or do not even guess why this happens. Especially ordinary users of USB 3G modems.

So what happens in fact and why 3G works slowly, then very quickly. When connected, everyone noticed that the modem is connected in 3G mode, but in the process of work suddenly switches to EDGE or what is worse - it throws out of the network. In everything is to blame the automatic search mode for a stable signal - here's a modem and jumps on WCDMA, then on HSPA, and even at all on Edge. Example: EDGE Signal 96%, WCDMA Signal 90%, HSPA signal 50% -60%. That is, the modem automatically selects the mode in which the signal is caught most confident. Naturally, three of these examples will work in EDGE mode. Next, I will tell you how to make the modem work only in the finest mode - HSPA.
We open our MegaFon-Internet utility (consider on the example of the megaphone operator). Click the settings, then the network, we see:
Type of network - Here we choose only WCDMA
Range - Here we put GSM900 / GSM1800 / WCDMA900 / WCDMA2100
Registration mode - manual search, click update, wait, then select Megafon (3G) - we click on it and click registration.
Close the settings window, connect to the Internet.
After connecting, you will carry the mouse pointer to the 3G icon - it is located in the MegaFon Internet program in the left corner from above (in the old version of the program left below, instead of the 3G WCDMA icon). We see in what mode our modem works - WCDMA. Now we need one small program - it is called HSPA Locker 1.3b (I use it exactly). Download it. Unpack, run, but do not press Start. Where the divisions are located in the program, we put a maximum of 3.0 KB - you can then test by selecting the down mode. So now begin to intensively download anything through any download manager. We see that the signal in the MegaFon-Internet program was not WCDMA, and HSPA (or HSDPA is the same thing). Now click the Start button in the HSPA Locker program. After we turn it out in the tray and turn off what they put on the download. We admire the results: in the MegaFon-Internet program, the connection always shows HSPA. The program chases tiny traffic within the network and the modem works in the highest possible mode. 50% signal for stable operation HSPA is quite enough. Why all this is done.
The first - so we reduced Ping from 1000 to 600.
The second - now the pages have become very easy to open.
The third - our favorite online games do not stupid!
Well, the most pleasant thing - your internet will stop constantly disconnected. That is, for stable operation, the modem needs to be set only one mode of operation.
