Overview
How fast is your D-Smart İnternet connection really?
D-Smart İnternet is an ISP offering fixed home internet over fiber, VDSL and ADSL. It builds no last mile of its own; depending on the address, service runs over wholesale fiber (FTTH) or copper last mile (VDSL/ADSL) infrastructure. Your real speed varies with plan type, infrastructure and modem; the test lets you easily compare your committed speed against the real result.
Plans
D-Smart İnternet plans and expected speeds
The values below are the committed speeds of typical retail plans; your real result varies with infrastructure, device and connection type.
| Plan | Download | Upload |
|---|---|---|
| Fiber 100 | 100 Mbps | 20 Mbps |
| Fiber 200 | 200 Mbps | 20 Mbps |
| Fiber 1000 | 1000 Mbps | 50 Mbps |
Speeds and prices are indicative and may change; confirm current plan terms with the provider.
Why it varies
Factors that affect internet speed
Wi-Fi or cable?
On Wi-Fi, signal strength, distance and interference reduce speed. A wired (Ethernet) connection reveals your line's true capacity.
Infrastructure and distance
Fiber speed is distance-independent; VDSL/ADSL drops with distance from the exchange. On mobile, signal and cell congestion dominate.
Device and modem
An old network card, weak CPU or a non-Gigabit modem becomes a bottleneck on high-tier plans.
Simultaneous usage
Downloads, streaming and gaming on other devices share the same line and lower your measured speed.
Peak hours
Evenings (8 PM-midnight) are peak; local node or international link congestion can cause minor drops.
Server distance and latency
The test server's distance affects ping (latency) and jitter. NETMETRİK selects the nearest high-capacity server.
Accurate testing
How to measure your speed correctly
- 1If possible, connect your computer to the modem with an Ethernet cable; Wi-Fi can show a result below the line.
- 2Pause downloads, streaming and updates on other devices so only the test uses the line.
- 3Turn off any VPN/proxy and 'data saver' mode in your browser or operating system.
- 4Close other tabs, press the START button at the top of the page, and avoid other activity until the measurement finishes.
- 5Take several measurements at different times, save them, and compare the average against your plan speed.
FAQ

How do I accurately test my D-Smart speed?
Connect your computer to the modem with an Ethernet cable, pause downloads on other devices, and press START. Testing over Wi-Fi can show a result below the line, especially on high-tier plans.
