Our ratings on the decisive factors for choosing NETGEAR D6400 Wi-Fi modem router

1. Internet connection: Rated 8.5 out of 10

Netgear D6400 ReviewThe Netgear D6400 is a mid-range modem router that continues to be very popular: despite having been put on the market for a few years, in fact, it has some features still able to meet the needs of many users.

As for the internet connection, it offers a very widespread standard both among the mid-range models and among the more expensive ones.

It is, in fact, compatible with both ADSL and all its subsequent versions (ADSL2 and ADSL2+), and with VDSL/2, and can be used both with older connections, as long as it is of the FTTC type. If fiber optic cables reach directly inside your home (FTTH), this Wi-Fi modem router cannot be used.

2. Network connection: Rated 9 out of 10

D6400 ModemRegarding the possibility of a wireless and wired connection, the Netgear D6400 continues to offer good performance. It is a Dual Band model, with which it is possible to take advantage of both the 2.4 GHz band, especially suitable for online activities that do not require particular speed or the transfer of a large volume of data, and that of 5 GHz for operations more complex.

The Netgear D6400 is compatible with the 802.11a/b/g/n/ac wireless standard, among the most up-to-date on the market and able to guarantee some features that we will see in more detail in the next paragraph.

The maximum achievable speed amounts, summing the two bands, to 1600 Mbit/s, a sufficient datum for most of the connections diffused in the UK, even if inferior compared to some models of slightly higher range.

As for the wired connection, the Netgear D6400 ensures a good data transfer speed thanks to the Gigabit Ethernet standard, capable of reaching 1000 Mbit/s.

3. Antennas: Rated 8.5 out of 10

Unlike many other models of the same brand, the Netgear D6400 has three integrated antennas, placed therefore inside the body. Although many still associate external antennas with better performance, the possibility of orienting them in the preferred direction is now practically useless thanks to the most advanced technologies of which by now almost all medium-high-end Wi-Fi modem routers are equipped.

As we mentioned in the previous paragraph, the maximum total speed reaches 1600 Mbit/s, distributed between the 2.4 GHz band (300 Mbit/s) and the 5 GHz band (1300 Mbit/s). This model is also equipped with Beamforming and MIMO technologies, which together reduce the dispersion of the wireless signal, also increasing its stability and coverage.

4. Hardware connection: Rated 7.5 out of 10

Netgear VDSL RouterRegarding the possibilities of hardware connections, the Netgear D6400 can offer average performance, although not impressive.

It has a DSL socket, a WAN port and four LANs (all updated to the Gigabit Ethernet standard) and two USB 2.0.

These can be used to connect external storage or a printer, while it is not possible to connect 3G or 4G internet keys to take advantage of a mobile network even in the home.

It should also be noted that the USB 2.0 standard does not allow a particularly high data transfer rate, making this model less suitable for media server functions than other competitors equipped with USB 3.0.

5. Other functions: Rated 7.5 out of 10

As for the additional features, the Netgear D6400 is quite in line with other mid-range products. From a security point of view, it is definitely a valid product: it uses WPA2 coding, offers options for parental control and for creating a secure network for guests, as well as having a pre-installed firewall.

Even the management of data traffic is made very simple for the user thanks to the Quality of Service option, which allows giving priority to a particular device, particular PC or game console for online gaming enthusiasts.

Concerning telephony functionality, however, this modem router is not particularly advanced. In fact, it does not support VOIP technology, and it does not offer particular options that help to manage the analogue and digital telephony more quickly and effectively.

The Genie application should be mentioned, with which you can remotely manage your network using your smartphone.

User reviews

Most users are satisfied with the purchase of the Netgear D6400, underlining the excellent value for money, the speed of navigation allowed and the ease of configuration, at least for the basic options, thanks to the Genie application. Some critics report problems of frequent disconnections and malfunctions after a short period of use.

NETGEAR D6400 final score: 8.2 out of 10

Netgear D6400-100UKSThe Netgear D6400 gets a total score of 8.2 out of 10.

This mid-range Wi-Fi modem router can support all DSL connections (ADSL/2/2+ and VDSL/2), while it is not compatible with FTTH connections, those in which fiber optic cables reach the interior of the home.

As for the network connectivity, it supports the Wi-Fi 802.11a/b/g/n/ac standard, among the most advanced currently on the market, while the wired connection is updated to the Gigabit Ethernet standard.

The three antennas inside the body make it possible to take advantage of both the 2.4 and 5 GHz band and reach a maximum speed of 1600 Mbit/s.

Thanks to Beamforming and MIMO technologies they can also guarantee an intelligent distribution of the wireless signal, in addition to its greater power and stability.

The possible hardware connections are many: the Netgear D6400 has, in fact, a DSL socket, four LANs, a WAN and two USB 2.0, to which external hard disks or printers can be connected, but not 3G or 4G keys.

The additional features are positive with regards to security (firewall, parental control, guest network) and data traffic management (Quality of Service), while they remain scarce in terms of telephony management.

We recommend this Wi-Fi modem router to users looking for a device that can offer good speed and a powerful signal, but not interested in very advanced features. We do not recommend it, however, especially to those looking for a product that can also handle telephony.
