ADSL Cat Smart settings: Accelerate your network

The first trick: solving interference

A friend's network has been relatively normal, but recently a little strange fault. Network daytime generally more normal, night "big cat" is often interrupted. He unloaded the computer several times, the ADSL line checked n times, the result is not helpful. Just when he was almost desperate, a friend told him that if you put the computer to another place, it would be normal for the big cat. Change back to the original position, and not normal. What's the reason? Watching a friend's new installed air conditioner rumbling, thinking to himself, is it the culprit? The air conditioner was turned off and the network returned to normal immediately. Originally, in the peak electricity, because the air-conditioning power is relatively large, causing line voltage is too low, at the same time, air-conditioning and the computer's current circuit connection, the "big cat" work caused interference, resulting in the normal Internet. I found that with the popularity of high-power electrical appliances (such as air-conditioning, microwave ovens), and the old lines did not change in a timely manner, similar failures are more and more. Because the broadband to the disturbance, the power supply stability request is very high. Therefore, it must be reformed.

1. Separate pull from the distribution plate

The condition can be from the user transformer under the Low-voltage power distribution plate alone of course, the most ideal, followed from the flat of the total distribution cabinet pull line, attention must be avoided high-power electrical equipment. As the current circuit is independent, it avoids mixing with the current circuit of other electrical appliances, thus effectively reduces the interference and realizes the mutual isolation. In fact, in the use of high-power electrical equipment, the original request to use the special line, but most people do not mean it. If you have the conditions, you can also choose the power purification equipment, the power supply purification, the effect is better.

2, "big cat" power to use a separate socket, do not share a socket with other equipment

I often see on the Internet by the power source caused by the failure of the post, some technicians are advised to use a separate socket. Also some netizens believe that the "big cat" power quality is generally bad, anti-interference ability is particularly poor, especially for a long time to use a severe fever, resulting in equipment failure. Therefore, it is recommended to switch to high-quality power supply (only the price is more expensive).

3, the equipment (including the host) for good shielding and grounding

Have you ever tried to make a phone call with a cellphone next to "Big cat"? Mobile phone in the connection to the interference, at a certain distance enough to make the network flow. Similar electrical appliances now a lot, in addition to pay attention to not close to the "big cat" outside, there is no active protection measures? Of course it is! We can use tin to shield the "big cat" and then ground the shielding layer. When grounding, must pay attention not to connect in the pipe or the lightning rod line, otherwise, will cause the bigger disturbance, if you do not believe, may use the oscilloscope measurement, the above interference itself is very big. Therefore, it is best to use a separate ground wire, no electrician knowledge friend, must ask the expert to help you do ground connection, otherwise, light on the equipment cause interference, heavy endanger equipment or personal safety. There is no grounding to the host friend, at this time must be good grounding, do not forget that the host is also using electrical appliances, will also cause interference to the equipment.

The second trick: Choose the big Cat.

ADSL speed is far higher than dial-up Internet, the "big cat" requirements are higher. Unfortunately, some local telecom "big cat" is not easy to use. Under the same conditions, with the help of a friend of the Telecommunications Bureau, I experimented with the "big Cat", which was presented to 1680 and telecom, and found that the former was much faster than the latter. When asked about the reason, the friend smiled: maybe it's because of the price. If you have the conditions, you may wish to use some big brand modem.

1, the main chip

In the choice of "big cat", we should first pay attention to the main chip that it uses. I recommend using Conexant Chip "big cat", in the use of dial-up Internet, we are not unfamiliar with the Rockwell, it's speed and stability has been praised by everyone, in fact, The Rockwell Semiconductor System is a subsidiary of Rockwell, which is specialized in providing products for the market of communication chips, and has now been renamed Conexant.

2, Compatibility

Before you buy, you'd better ask the telecommunications Bureau about the type of local equipment used, the protocols adopted, VCI, VPI, and so on to determine if it is compatible with the "Big cat" you purchased. Some "big cat" and end equipment compatibility is not good, resulting in no internet access. In the process of normal Internet access, if the ISP's local equipment has changed, this problem will also occur. There is a netizen, the use of broadband nearly half a year, the recent occurrence of an anomaly, that is, often drop lines, and then resynchronize, very frequent, up to 10 minutes on the line 5~6 times, the youth is 2-3 hours, most of the time is 20-30 minutes, which greatly affected the work. What's going on? Originally is the Telecommunications bureau upgrades the terminal equipment, download firmware version of the program to "Big cat" refresh, the problem is completely solved. So in the purchase time must buy the manufacturer's products, so that when the upgrade can be timely service.

3, interface

Try to choose the external modem of the Ethernet interface. Although the modem of USB interface has the advantages of not using external power, it also has some disadvantages such as consuming CPU resources and not being stable on some motherboards. The disadvantage of the built-in modem is that it is susceptible to electromagnetic interference in the machine.

4, heat dissipation

Many people just pay attention to the "big cat" on the top of the heat, I found that many brands of "big cat" bottom is hotter. So in the use of the best to put it up a little, so that the air can flow, will be better. Of course, it is best to use air-conditioning, so that you and the computer do not have to worry about the heat.
