ADSL vs. ADSL2: Know the Difference
By Shumaila Saeed || Published on February 3, 2024
ADSL provides internet over copper phone lines with max speeds around 8 Mbps, whereas ADSL2 offers improved speeds up to 24 Mbps and better stability.
Key Differences
ADSL (Asymmetric Digital Subscriber Line) is an early broadband technology using existing phone lines for internet, with download speeds maxing at about 8 Mbps. ADSL2, an improved version, boosts maximum speeds to around 24 Mbps, using the same lines but more efficiently.
