Being a 12-stream dual-band router, the Nighthawk RAX120 supports four streams on the 2.4GHz band and eight streams on the 5GHz band with total speeds of up to 4,804Mbits/sec. The RAX120 is one of Nighthawk's AX12 version; the other version being the RAX200, which is a tri-band Wifi 6 router. The Nighthawk RAX120 version supports 80 MHz and 160 MHz bandwidth channels (80+80 MHz), as well as DFS (Dynamic Frequency Selection) channels, which is particularly useful if you live somewhere surrounded by residential flat properties often flooded with Wifi hotspots all competing for the same 11 Wifi channels.
Via DFS, you can set your Wifi channel range to a non UK range, using radar 5 GHz frequencies. DFS support is also useful if you're using a Wifi extender (i.e. EX8000) that requires a high DFS to allow the 1733 backhaul link. During setup, 160 MHz bandwidth can be enabled but it's worth noting that only compatible devices will connect to 160 MHz bandwidth channels. The channels used for 160 MHz bandwidth don't have to be in a direct sequence; hence you can have any 20 MHz master channel within a block of four 20 MHz channels (forming 80 MHz).
Bolstering the Nighthawk RAX120's security is Netgear Armor, which is an add-on software that you can install from the Nighthawk app to strengthen the protection of your home network. Netgear Armor basically acts as a DNS filter for your entire home network, blocking access to certain websites. From the Netgear Armor, you can also enable Bitdefender Security for every device on your home network, giving you access to useful features such as parental control and anti-theft, which allows you to track the geographical location of any device.
Netgear currently has a free 30-day trial, which maybe worth trying out, particularly if you have a large family and/or business with multiple computers/devices. Also, because Bitdefender is already integrated with Netgear Armor it does not seem to affect the network connection speed, which is a likely downside if you buy cybersecurity and anti-virus software separately. The Nighthawk app also serves as the medium for setting up the Nighthawk RAX120.
The Nighthawk app integrates several useful features such as "speed test" so, you can check the Internet speed all within the same Netgear ecosystem. Another neat feature you can enable from the Nighthawk app is Smart Connect, which puts the 2.4 Ghz and 5 Ghz bands on the same SSID and then allows the Nighthawk RAX120 router to automatically decide which SSID band to connect each device to. This is useful because it allows network devices to automatically roam to the band that suits their needs best.
Smart Connect works well if all the devices in the network are fast and/or support MU-MIMO and have similar channel widths. If this is not the case, you may actually want to keep Smart Connect disabled as you will get better performance by having different SSIDs for 2.4 and 5 GHz and manually assigning each device to each SSID. Ideally, you want to put N devices on the 'slower' 5Ghz band and AC devices on the 'faster' 2.4Ghz band but, you don't want to have too many devices sharing the same SSID band at the same time because it will slow down all the devices.
The Nighthawk mobile app also integrates a signal strength feature for tracking Wifi signal, using an analogue test meter style with a swinging needle going from not good to amazing. One thing you cannot do from the Nighthawk app though, it's to manually turn on the RAX120 built-in fan. That said, the router thermal management works well at keeping the unit cool but, if you want to run the fan all the time, you can enable it always on via Netgear's debug.htm hidden page (http://192.168.1.1/debug.htm).
The Nighthawk app requires a new account creation, unless you already have an account from a different Netgear product. Both the Nighthawk app and Orbi app are linked to the same Netgear database so, if you have already signed up to a different Netgear product, you won't have to create another account. Setup takes up to 15 minutes and it's straightforward, thanks to the on-screen prompts. You can manually register the unit but, using the QR scanner function is much quicker.
Before connecting the Nighthawk RAX120 to your own rooter/modem, you want to power off the rooter/modem (just like the on-screen prompt says) or the setup will not complete successfully. If you are using the existing router provided by your ISP broadband, the Nighthawk app does not require setting the router to modem-only. However, you do want to disconnect anything from your existing router to prevent any possible issues like double NAT, which will give you problems when playing online games, as well as using port forwarding rules. From the Nighthawk mobile, you are also able to update the firmware. The current firmware version, as of January 2020, it's v1.2.0.16.
The Nighthawk RAX120 really has a sleak wing design with metal folding hinge antennas that fold like a laptop. The fan is located on top of the unit covered by a metal grille mesh. More cooling vents can be seen on the base of the unit, which also features four rubber feet and two hole openings for all mounting the unit. The location of the fan on top means the Nighthawk RAX120 sucks in air from the top rather than underneath like with other routers, which is ideal from a cooling perspective. The trade off though, it's the dust ingress since there is not dust-proof mesh filter protecting the fan. More black anodized metal grille mesh styling can be seen running vertically across from the fan mesh.
