What is Wi-Fi?
Although some users still use Lan cable to access the Internet to take advantage of higher speed or for other reasons, but for years almost all users They use Wi-Fi technology to connect to the Internet. This technology arrived in 1998, but about 10 years later it became a pervasive technology.
The devices connected to Wi-Fi network convert the data into radio signals and in this way various data can be sent and received. Wi-Fi signals travel at 2.4 or 5 GHz frequencies. Signals placed on the 2.4 GHz band provide a maximum speed of 450 Mbps, but signals based on 5 GHz networks can reach a maximum speed of 1300 Mbps. Currently, there is also a 6 GHz frequency, although only a small number of modems and devices support this frequency.
Of course, these numbers are related to completely ideal conditions, and in the real world, due to real limitations, users They face a much lower speed.
What is a modem and what is its use?
Telecom company AT&T unveiled the first modem in 1960 and years later in 1970, the first home modem was officially unveiled. For years, dial-up modems were used, which had very low speeds. But in the early 2000s, broadband internet became more widespread and as a result new models of modems appeared. Currently, at least in Iran, ADSL Internet is considered the most common technology for home Internet, which uses copper telephone wires to transmit data.
The modem also receives analog signals in simple language and after converting to Digital signals provide this information to devices. Meanwhile, the opposite of this process should also be done.
What is a router and how is it different from a modem?
A router is a device that allows multiple devices to share the same internet connection. Years ago, ADSL modems were just regular modems and users could connect a computer to it using a LAN cable. But when users want to connect multiple devices to the Internet, they should use a router. This means that the router must be connected to the modem and then broadcast data between the devices.
Routers are divided into two main categories: wired and wireless. Wired routers receive data from the modem and by providing several outputs, you can connect a number of Lan cables to it and use the Internet. But wireless routers naturally do not behave like this and after connecting to a modem, they can create a Wi-Fi network and in this way, users are able to connect different devices to the Internet.
Modem router How does it work?
As we said, the modem It receives information from a wire or source and then presents this information as understandable data for computers and other devices. The router can provide this data to different devices. Years ago, most modems were just modems and users had to buy separate routers to connect different devices. But now if you are looking to buy an ADSL modem, we must say that almost all of them are router modems. This means that in addition to performing the duty as a modem, they are also routers and you don't have to incur more costs.
How to increase modem security
After purchase ADSL modem, you need to set up its Wi-Fi network. Considering that the username and password of the modem settings section is usually in the default mode of Admin, you must change the password at the very beginning. If you suspect that others are abusing the modem after using it for a while, you can see what devices are connected to your modem through the modem settings section. If you see any suspicious devices in this list, you can throw them out of the modem and it is even possible to block their connection forever. Of course, the other party can change the MAC address of their device and access the modem again to find Therefore, this solution is not very useful.
Some old encryption methods such as WEP, WPA1 and WPA2- TKIP has very low security. For example, passwords based on the WEP standard are easily hacked within seconds. Therefore, if you are still using these standards for your modem, it is time to use new standards such as WPA2 Personal or WPA3 Personal (if the modem supports it). Therefore, be sure to pay a lot of attention to the protocol used for the modem password, because if you have used an old protocol, the probability of hacking the modem and penetrating it is much higher.
Widespread disruptions in Iran are not a new issue, but in the meantime, sometimes due to problems in the home Wi-Fi network, you face the problem of slowing down. So after you are sure that there is no problem with the received internet speed, you should consider some things to check this issue. Have it and these types of modems usually don't provide very high speed. On the other hand, if the internet speed is low, no miracle will happen by changing the modem. Another important point that you should pay attention to is the location of the modem. If you place the modem in the wrong place, the signal quality will be significantly weaker than expected. For this, you can use applications related to checking the Wi-Fi signal strength. How many devices use your modem. Of course, this is usually not a problem with the modem because if your Internet does not have a very high bandwidth, naturally, by connecting several devices to the modem and using the Internet, the Wi-Fi speed will decrease significantly. In the meantime, we should not ignore the importance of Wi-Fi channels being crowded. This issue mostly happens to devices based on the 2.4 GHz band, and if you use the 5 GHz band, you usually do not face this problem. But in any case, if you live in an apartment or residential areas with high density, it is better to solve this problem by using special applications provided for this issue.

Increasing Wi-Fi signal range with amplifier devices
Wi-Fi extenders devices that Usually, they are also referred to as Range Extenders, by receiving the Internet from the modem and re-broadcasting it to distant points, it expands and strengthens the Wi-Fi network. According to the way Wi-Fi works and how the extenders are connected to the main router, every gadget that is connected to the extender reduces the bandwidth. Of course, if you don't put a lot of pressure on the internet, you won't feel such a problem.
But in general In addition to bandwidth reduction, most of these devices cause network lag, and on the other hand, if you buy cheap models, they cannot support a large number of devices. Also, if you use some of these devices, you may face frequent Wi-Fi network outages. Therefore, in general, it is better to spend your budget on buying a better modem with a wider Wi-Fi signal range instead of buying these types of devices. ADSL in SafirSoft
