Hands on: I tried the Zyxel FWA510 – read what I thought of this WiFi router

Zyxel has been steadily building up an extensive range of 5G NR mobile routers, and the FWA510 is one of its most versatile yet. This desktop unit takes everything we liked in Zyxel’s NR5101 and claims a doubling in Wi-Fi 6 performance, adds essential 2.5GbE multi-gigabit network ports and teams up its four embedded omnidirectional antennas with an option to add four TS9 external aerials for improved reception.

The FWA510 is slightly larger than the NR5101, and the status LEDs have been moved from the front of the unit to the sloping upper surface. These will prove useful as they alert you if an SMS message has been received, use a multicolored LED to show cellular signal strength and provide visual cues for internet connectivity and wireless status.

The rear interface panel has also been redesigned and now has a faster USB-A port for sharing storage devices. The second multi-gig port can function as a LAN or WAN interface and, if you choose the latter, it takes precedence over the cellular connection, which drops back to standby mode for automatic failover services.

The FWA510 is easy to install, with its local web interface provides a wizard to get you up and running. Our unit was supplied with a Vodafone 5G SIM snuggling in the 3FF slot in the base, which provided instant cellular internet access.

The web interface presents a dashboard showing the status of local and internet connections, cellular status and details of wireless networks. A default SSID is provided for both radios and, although it uses the weaker WPA2 encryption, you can easily swap to the more secure WPA3.

Four SSIDs are supported, with three guest wireless networks already configured. These can be modified to suit, with the Guest WiFi tickbox enabling L2 isolation so users on these SSIDs only get internet access.

General network security is good. An integral firewall offers three protection levels that you choose using a slider bar, and you can add custom firewall rules that comprise protocols and port numbers, plus access control list (ACL) entries to control connections for source and destination IP addresses and services.

So far, so good, but we came across an issue with the router’s wireless services. Zyxel claims it delivers up to 2,400Mbits/sec on the 5GHz radio (hence the AX3600 rating), but to achieve this it must support the high-speed 160MHz channels.

At present, the web console’s wireless settings for the 5GHz radio offer a 20/40/80MHz option, so our test clients could only connect at 1.2Gbits/sec. Consequently, copies of a 25GB test file between a Windows 11 Pro workstation equipped with a TP-Link Archer TXE75E Wi-Fi 6/6E adapter and a server on our 10GbE LAN maxed out at 108MB/sec at close range, dropping to 86MB/sec with the router ten meters away in the next room – only marginally faster than the AX1800-rated NR5101.

The FWA510 can be cloud-managed from Zyxel’s Nebula Control Center (NCC), and we added it to our account by scanning its QR code from an iPad running the Nebula iOS app. A status widget can be added to the NCC site dashboard, and selecting it provides more hardware details along with views of WAN and cellular status, 24-hour traffic graphs and information about wired and wireless clients.

Unlike Zyxel’s fully compliant Nebula wireless APs, the FWA510 doesn’t broadcast the cloud SSIDs as these must be configured from its own web interface. Upgrade to an NCC Pro Pack license and the remote configurator tool can load this directly from the NCC portal and will also increase traffic monitoring to 30 days.

Zyxel’s FWA510 and its 5G NR support will appeal to home workers in rural areas and remote offices that demand always-on internet access. It’s easy to use and can be cloud-monitored but, unless a firmware upgrade materializes, its Wi-Fi 6 services are no faster than the NR5101 it’s replacing.
