The DSL-124 is a workhorse. It’s an ADSL2+ modem and a router rolled into one. It’s the "all-in-one" solution that ISPs love to hand out. But being a workhorse means it’s often overworked. It manages your IP addresses, handles your firewall, broadcasts two separate Wi-Fi frequencies (2.4GHz and 5GHz), and translates the DSL signal from your phone line into data.
The DSL-124 combines an ADSL2+ modem with a 4-port Ethernet switch and an 802.11n wireless access point. The firmware serves as the operating system (typically a Linux-based embedded system) controlling the device's logic, routing tables, and security protocols.
