Description

Description

The AC21 by Tenda is a router that distributes internet access to other devices, either wirelessly or via cable. It is a Wi-Fi 5 generation, the most widespread Wi-Fi standard, meeting the needs of most users for now. The next generation Wi-Fi 6 is recognized, which offers the ability to connect more devices.

The device emits a signal on two frequencies:

  • 2.4GHz: Predominant frequency with a wide range.
  • 5GHz: Provides higher speed but is more sensitive to obstacles.

The device supports VPN (Virtual Private Network) setup, offering anonymity and access to geographically restricted content. Certified VPN services are usually paid with a subscription.

With MAC address filtering, it allows specific devices to connect based on their unique MAC address.

It offers WPA2 security, using AES (Advanced Encryption Standard) technology, which is approved by the US government for confidential documents and is considered secure for home use.

Maximum Wireless Speed: 2100Mbps

Maximum LAN Speed: 100Mbps

Type
Router

Type

The devices we encounter are standalone routers, routers with built-in modems, and mobile routers.

A router requires a separate modem and distributes the connection to multiple devices via Wi-Fi or Ethernet, but cannot connect directly to the internet. A modem/router combines a modem and router in one device, connects directly to the internet provider, and distributes the connection to the local network. A mobile router, on the other hand, uses a SIM card and mobile data to create a portable Wi-Fi hotspot, ideal for use outside the home or in areas without a fixed connection.

Router

Plain router (without modem). The router is a device to which other devices (e.g. computer, mobile, TV) connect either wirelessly or with a cable, and it shares internet access with them. It receives internet access through a separate device called a modem.
Maximum Wireless Speed
2100 Mbps

Maximum Wireless Speed

Theoretical maximum speed with a wirelessly connected device primarily used for marketing purposes. The speed of each connected device depends on factors such as distance, obstacles, the number of other devices connected, the number of other networks in the same area, etc.
Maximum LAN Speed
100 Mbps

Maximum LAN Speed

The maximum speed that the modem/router can offer to devices connected to it via ethernet cable.

100
Usually, 100Mbps is sufficient for the needs of most users. For more demanding uses such as transferring large files (e.g. high-definition videos), prefer a device with support for 1000Mbps. Note that all involved devices must support this speed, otherwise data transmission will be limited to the speed of the slowest device.
Portable Hotspot
No

Portable Hotspot

Mobile routers with built-in battery so you can use them anywhere.

These mobile routers have a SIM card slot for wireless internet access through 3G/4G mobile networks.
Wi-Fi Generation
Wi‑Fi 5

Wi-Fi Generation

The Wi-Fi generation is a more user-friendly term for networking standards that affect maximum Wi-Fi speed, distance, sensitivity to obstacles, etc.

Wi‑Fi 5
The most widely used Wi-Fi standard, significantly faster than Wi-Fi 4. Wi-Fi 5 can currently meet the needs of most users. The next generation (Wi-Fi 6) began to be released in 2019 and offers the ability to connect many more devices to serve the increasingly smart devices in a home. Each newer generation is compatible with devices that support a previous one.
Network Standards
IEEE 802.11a, IEEE 802.11 b/g/n, IEEE 802.11ac, IEEE 802.3/3u

Network Standards

The device supports various networking standards that affect the maximum Wi-Fi speed, distance, sensitivity to obstacles, etc. This information is also reflected in the more user-friendly Wi-Fi generation. It is recommended to choose a Wi-Fi 5 (IEEE 802.11ac) or Wi-Fi 6 (IEEE 802.11ax) device.

IEEE 802.11 b/g/n

The older Wi-Fi standard, known as Wi-Fi 4, is significantly slower than Wi-Fi 5 (IEEE 802.11ac) and Wi-Fi 6 (IEEE 802.11ax).

It is recommended for use with few devices and for applications that do not require high speeds. For most users, it would be preferable to choose a Wi-Fi 5 or 6 device according to their needs. Each newer generation is compatible with devices that support a previous one.

IEEE 802.11ac
The most common Wi-Fi standard, known as Wi-Fi 5, is significantly faster than Wi-Fi 4 (IEEE 802.11 a/b/g/n).

Wi-Fi 5 can currently meet the needs of most users, but there is now the next generation Wi-Fi 6 (IEEE 802.11ax) which offers the ability to connect many more devices to serve the increasingly smart devices in a home.

Each newer generation is compatible with devices that support some previous one.

Security

Encryption Protocols
WPA, WPA-Personal, WPA2, WPA2-Personal, WPS

Encryption Protocols

The security protocols supported by the device for encrypting data transmitted wirelessly and protecting against third-party connections to your network.

The first protocol was WEP, which was replaced by WPA, which in turn evolves into generations with each generation having a corporate and home version. Anything older than WPA2 is not considered secure.

It is recommended that the device support at least WPA2-Personal (PSK) for home use.

WPA

The WPA protocol was a temporary significant improvement over WEP, but still vulnerable and outdated. It has now been replaced by WPA 2.

WPA-Personal
The WPA protocol was a temporary significant improvement over WEP but still vulnerable and outdated. It has now been replaced by WPA 2. WPA-Personal is intended for home use sacrificing security, compared to WPA-Enterprise, for easier installation, using the PSK certification process (pre-shared keys).
WPA2
The WPA 2 protocol replaced WPA in 2004 and uses AES (Advanced Encryption Standard) technology, which is approved by the US government for classified documents. It is considered secure for home use.
WPA2-Personal
Replace WPA in 2004 with AES (Advanced Encryption Standard) technology, which is approved by the US government for confidential documents. It is considered safe for home use. 2. WPA2-Personal is intended for home use, sacrificing security compared to WPA2-Enterprise for easier installation, using the PSK (pre-shared keys) certification process.
WPS
WPS (Wi-Fi Protected Setup) offers an easy way to connect new devices to your network (e.g. by pressing a button), but it has been found to be vulnerable to attacks and is recommended to be disabled wherever possible. This security gap is considered a risk mainly for corporate applications as it is very rare for an individual to be targeted.
MAC Address Filtering
Yes

MAC Address Filtering

MAC (media access control) address filtering is the ability of a device to allow specific devices to connect based on their unique MAC address, while excluding any device with a MAC address that has not been defined as acceptable.

Extras

Virtual Private Network (VPN)
Yes

Virtual Private Network (VPN)

The device has the ability to set up a VPN (Virtual Private Network) so that traffic from all devices on our network passes through it. 2. The VPN acts as an intermediary between us and the rest of the internet. This way, we can give the impression that we are geographically located in another country and the pages we visit see the VPN address as the visitor's address, not ours. 3. This provides us with anonymity and access to content with geographic restrictions (e.g. some YouTube videos are only available in certain countries, the Netflix catalog is different depending on the country, etc.). 4. VPN services are usually paid for by subscription.
VoIP
No
Mesh
No

Mesh

It is a complete home WiFi system with multiple access points designed to eliminate dead zones and provide seamless WiFi throughout your home with higher speeds and more devices.

    First of all, it is more of an access point and then a broadband router. It takes the IP you have and gives 192.168.0.x internally with its own DHCP, but it does not see the TV if it is not connected to this network. Its 6 antennas divide the signal, which means many devices like me with 8 Wi-Fi cameras, 8 lights, 2 tablets, and 2 mobile phones. The signal between 2.4 and 5 is shared without any problem. And it never seems to have a bottleneck. Placement, like all access points, should be high at 2 meters, and if you can, a small UPS, especially if there is an alarm, cameras, a recorder, and automations
