TP-Link TL-WR840N 300Mbps Wireless N Router

TP-Link 300Mbps Wireless N Router (TL-WR840N) - 3 Years Local Warranty

The TL-WR840N is TP-Link's entry-level N300 wired-and-wireless router for a flat or a small office. It carries 300 Mbps of 2.4 GHz Wi-Fi 4 across two fixed antennas, one 10/100 Mbps WAN port and four 10/100 Mbps LAN ports, and it can be switched between Router, Access Point, Range Extender and WISP modes, so one box covers several common Singapore deployments.

N300 Wi-Fi Across Two Fixed Antennas

TP-Link rates the TL-WR840N at 300 Mbps on the 2.4 GHz band under IEEE 802.11n/b/g, and describes its coverage as suited to two-bedroom homes using two fixed antennas. That is a Wi-Fi 4 class radio built for browsing, email, messaging and standard-definition streaming rather than for a house full of 4K devices. For an HDB flat, a study, a shop counter or a site office where the requirement is a dependable connection rather than peak throughput, it does the job at the lowest cost in the TP-Link range.

Four Modes From One Device: Router, AP, Range Extender and WISP

The published working-mode list is Router, Access Point, Range Extender and WISP. In Router mode it terminates the broadband connection and runs NAT for the LAN. In Access Point mode it adds Wi-Fi to an existing wired network without a second DHCP server. Range Extender mode repeats an existing wireless signal into a dead zone, and WISP mode lets it take its uplink from a wireless ISP. That flexibility is what makes a low-cost unit worth keeping as a spare.

Five Fast Ethernet Ports for Wired Devices

The TL-WR840N publishes one 10/100 Mbps WAN port and four 10/100 Mbps LAN ports. The four LAN ports take a desktop, a printer, an IP camera or a set-top box directly, which keeps those devices off the wireless band and leaves more airtime for phones and tablets. Note the Fast Ethernet rating: these ports run at up to 100 Mbps, not Gigabit, so a fibre plan faster than 100 Mbps will be capped by this hardware. Ask us if you need a Gigabit model instead.

Guest Network, SPI Firewall and Parental Controls

Security is handled with an SPI firewall, access control, IP and MAC binding and an application layer gateway. Wi-Fi encryption covers WEP, WPA, WPA2 and WPA/WPA2-Enterprise, and one 2.4 GHz guest network can be published separately from the main SSID so visitors never touch the internal LAN. Parental controls cover URL filtering and time-of-day limits, letting a household put a curfew on a specific device. All of it is configured through the web interface or the TP-Link Tether app.

Setup and Day-to-Day Management

TP-Link publishes both webpage and Tether app management for this model. WAN connection types cover Dynamic IP, Static IP, PPPoE, PPTP and L2TP, which covers the common Singapore broadband handovers, and IPv4 and IPv6 are both supported. Other published software features include a DHCP server with address reservation, DDNS, QoS by device, NAT port forwarding, UPnP, DMZ and IPTV support. The unit runs on a 9 V, 0.6 A supply and measures 182 x 128 x 35 mm.

Ideal For

Singapore homes, rental units, small offices, shop counters and site offices on broadband plans up to 100 Mbps, and anyone who wants an inexpensive spare that can also be pressed into service as an access point or a range extender.
