The TP-Link TD-8840T is an ADSL2+ modem router designed to provide a stable internet connection for your home or small office. It supports ADSL, ADSL2, and ADSL2+ standards, allowing for downstream speeds of up to 24 Mbps, while the inclusion of Annex M helps to increase upstream data rates for smoother uploads. This device features a built-in switch with four 10/100 Mbps Ethernet ports, enabling you to connect multiple wired devices simultaneously. To keep your network secure and organized, it utilizes dual active firewalls consisting of NAT and a packet filter, alongside IP QoS and prioritization tools like ToS, DSCP, and 802.1p to ensure critical traffic gets the bandwidth it needs. You can also manage your household's online activity using the live parental controls. Measuring 165 x 108 x 28 mm, the router has a compact design with a white top and black base. It is built for reliability with 4000V lightning protection to safeguard the hardware during electrical surges.
