Quick guide based on usage:
For office – gamenet:
First, count the number of Lan ports. These ports should connect all of your computers by cat wires. If there are more computers than ports, buy a hub or switch alongside to the modem.
Then consider the number of modem antennas. Especially if your goal is more to use WiFi for the company or office than cable connection. The greater the number of antennas, the greater range it supports for wifi signals. If you have a distance of more than 100 meters, use a repeater.
Then consider speed, preferably using ac or n generation modems and using a dual-band modem (supporting both 5Ghz and 2.4 Ghz).
First, consider the bandwidth and number of antennas. Because all parts of the house must have access to WiFi ..
Especially if you live in an apartment, consider security and buy a modem with wpa2 support because WiFi hacking has become very easy these days.
Be sure to buy an ac generation modem, or at least n.
Tips for buying a modem
Number of ports
Usually the number of modem ports for connecting cable wires is 1 or 4 ports. A home port may be suitable for home use, where users usually connect from a mobile phone or laptop with Wi-Fi. But for office use, which is often connected to the modem by cable from computers, you must buy a 4-port modem. And if the number of these ports was not enough. Buy a separate switch and hub next to the modem .
WiFi is a standard ieee 802.11 technology. This technology includes generations and standards of, b,a,g,n and ac in order
the newer the wifi generation ,the more powerful and functional it is. right now a , b, g standards are no longer generated.
|150/300/450/600Mbps||5Ghz , 2.4Ghz||802.11n|
While mbps represents megabytes per second. There are 1,024 MB per gigabyte. So when you download a 1.5 gigabyte movie. At 150 mbps, it will take about ten seconds for the video to download. (But don’t be fooled by this table and the manufacturers’ descriptions. We’ll explain why in the “Speed” section)
Unfortunately, WiFi is not very secure. And because it is a station for sending and receiving information, it is the background to risks such as leak of bank card details, family information, and so on. And there are profiteers who want to use your internet. And because WiFi has low security, you need to take the necessary steps, such as removing the ability to connect automatically and choosing the right password to maintain WiFi security. When shopping, try to buy a modem with wpa2 support, which is one of the latest security features for WiFi .
Don’t be fooled by the speeds offered by modems manufacturer. Your internet speed depends on the provider company , for example, if your modem has a speed of 16 mbps, but the provider will give you a speed of 2 mbps. The speed at which you use the Internet will be a maximum of 2 mbps.
In addition, factors such as the number of users, the interference of the waves affect speed of your internet speed.. Currently for adsl2 + the maximum possible speed is 24 mbps for download and 3.3 mbps for upload.
Also, the generation of the computer network card (computer hardware that supports the network) must be equal to the generation of the modem to support its features. This means that if your network card is” 802.11 n” series and your modem is “802.11 ac” series. To connect your device, the modem lowers the generation level to n. So that the generation between the device and the modem is becomes similar and it will be possible to communicate.
The WiFi band is usually either 2.4 GHz or 5 GHz. Some modems have dual band capability that supports both types of bands. As a result, when the number of users is very high. The modem automatically balances the modem’s band users by connecting users to different bands (for example for two users on 5Ghz band modem transfers one user to 2.4Ghz band), so the speed won’t change too much .
Basically, modems have two types of internal and external antennas. External antennas have more power to cover a wider space. Also, the greater the number of antennas, the greater the vertical and horizontal range of wifi coverage.
This is a feature that fewer modems have. Because it is a modern feature. Until now, modems have worked in such a way that they transmitted the signal in space, and any device that had access to the signal in this environment could use it.
But beam forming is a new feature that , Instead of spreading the signal in space, it sends it to specific target devices. As a result, the signal is not wasted, so these modems will have better performance.
Modems with this feature have the ability to transfer large files such as videos, etc. more quickly. So if you have activities such as live streaming and uploading and downloading videos, keep this feature in mind when shopping
