Wi-Fi speed depends on the selected communication standard and the settings of the router-laptop pair (tablet, smartphone, etc.). But, as practice shows, many devices sold in the CIS countries have features that limit the full use of Wi-Fi technology.
Use 4 Wi-Fi standard connections:
- 802.11a - provides speeds of up to 54 Mbit/s at 5 GHz;
- 802.11 b - up to 11 Mbit/s at 2.4 GHz;
- 802.11g - up to 54 Mbit/s at 2.4 GHz;
- 802.11 n - up to 600 Mbps at 2.4 GHz.
Standards a And b have long been obsolete and are almost never used in practice. Standard g has existed for quite a long time, since its speed of 54 Mbit/s is quite enough for most users. In addition, the emergence of this standard coincided in time with the rapid development and penetration of Wi-Fi technology into the masses.
But the majority of end devices - laptops, netbooks, tablets, smartphones, which are imported into the territory of the CIS countries do not allow taking full advantage of the capabilities of the standard n . The maximum speed of the Wi-Fi adapter built into the device is limited to 65 Mbit/s. Information about the reason for limiting the maximum speed of a Wi-Fi adapter is quite contradictory. Some sources claim that this is due to the lack of SAT certification for a long time n in Russia. Therefore, manufacturers whose equipment is certified for sale in the Russian Federation have cut back maximum speed Wi-Fi on your devices. There is information that laptops purchased from foreign online stores do not have such restrictions.
But the fact is that certification this standard in the Russian Federation was made at the end of 2010, i.e. 2 years ago. It’s unlikely that manufacturers don’t know about this and continue to cut down adapters “out of habit.” wireless communication for devices supplied to the Russian Federation. Also in Russia, the position of the authorities regarding the need to obtain permits for using Wi-Fi devices.
In general, the fact remains a fact, and if anyone knows about the reason for limiting the data transfer rate on Wi-Fi devices supplied to Russia - I will be glad to see comments.
It should be noted that for some built-in laptops and netbooks Wi-Fi adapters There are alternative drivers and even alternative firmware that disable the maximum Wi-Fi speed limit. On the Internet you can find a lot of forums and articles on how to do this.
Sometimes it may be necessary to limit the speed of the router, or rather, the speed of data transfer from it to connected devices.
For example, this situation may arise if, due to large quantity connected devices slow down streaming video on the main computer.
Today the most common routers among ordinary users are TP-Link routers. That is why we will consider an example with such a router. Essentially, the settings in routers from different manufacturers are not much different, so based on this example, you can make similar manipulations with other routers.
How to limit the speed of a router?
In all TP-Link routers there is a special item in the settings Bandwidth Control, which is designed specifically to limit the connection speed with various devices. It is with this router menu item that we will work today.
Limit speed for all connected devices
TP-Link routers limit the connection speed to devices using the IP protocol, so we need to find a menu item in the settings DHCP(this is a separate tab with several sub-items).
To limit the speed, this router service must be enabled, so if it is disabled, you must enable it by checking the box next to “ Enable ».
After turning on the service, go to the menu item Bandwidth Control and enable this service using the same checkbox opposite the item “ Enable Bandwidth Control ».
Next, next to the menu item “ Line Type» select the type of existing connection. If this ADSL, then indicate it, if not, then put a tick next to the item “ Other ».
In field Egress Bandwidth indicate the maximum upload speed, and in the field Ingress Bandwidth you must specify the maximum incoming speed, that is, the speed allocated by the Internet provider.
Save the changes using the button " Save" and go to the tab, put a tick next to the item " Enebl e" and indicate the range of IP addresses of devices for which the connection speed will be limited. Since we want to limit the speed for all connected devices, we you must specify the IP range from 192.168.0.100 to 192.168.0.199 .
All that remains is to set the speed limit. To do this you need to fill in the fields Egress Bandwidth - Max Bandwidth(Kbps) and Ingress Bandwidth - Max Bandwidth(Kbps). Here we indicate the maximum outgoing and incoming connection speed for all connected devices.
Important! All devices will share the specified speed evenly.
Limit speed for a specific device
Since the router limits the speed by IP addresses, first we need to assign the MAC address of the connected device to a specific IP.
To do this, go to the settings tab DHCP - Address Reservatio n and press the button Add New… ».
Opposite the point MAC Address Enter the MAC of the device for which the connection speed will be limited. Then into the field Reserved IP Address assign an IP address to the device. In field Status put " Eneble" and press the button " Save ».
After this procedure the router should be rebooted .
Now go to the tab again Bandwidth Control - Rules List and click the button Add New…" According to the scheme described above, we indicate the IP address of the device, put a tick next to the item “ Eneble"and set the maximum download and upload speed. Save the created script with the “ Save ».
That's it, the router speed limiting procedure is completed.
