Copper lines have different limits
DSL performance can vary with line length, line quality, modem sync and the technology used by the provider.
DSL Speed Test
Check how a DSL or VDSL-style connection performs in the areas that matter most on copper lines: downstream speed, upstream balance and latency under load.

Run a live test
Measure the connection and get a result designed specifically for this test.
No result yet. The live test uses Cloudflare measurement endpoints and interprets the same core metrics differently for this page’s user intent.
Download—Mbps
Upload—Mbps
Ping—ms
Jitter—ms
Loaded latency—ms
The live measurement connects directly to Cloudflare. Results are estimates and can change with Wi‑Fi, VPNs, device load, server routing and network conditions.
Upload can become the hidden bottleneck
On asymmetric DSL services, a busy upload can increase latency sharply. That is why this result keeps upstream and loaded latency visible.
Wi‑Fi can mask the line itself
If possible, compare an Ethernet test before concluding that the DSL line is responsible for a poor wireless result.
