Boosting Your Connection Performance
Sometimes, DaDesktop might alert you if your connection seems to suffer from high latency (delay) that could hamper performance.
If that happens, take a look at the steps below to boost your connection here in Greece.

Steps to take
- Whenever possible, connect via Ethernet. If you’re on WiFi, run an online speed test (like speedtest.net) first to check your speed.
- Try to stay near the wireless access point. Opt for 5 GHz WiFi over 2.4 GHz if you can, since 2.4 GHz tends to be slower and more susceptible to interference.
- Turn off or disable any VPNs or proxies before joining the course.
- If feasible, turn off any security software that might interfere with the network, as these can sometimes increase latency or reduce speed.
-
Reach out to your company’s IT support team if you need help, particularly if your network uses content filters or other restrictions. Adding these domains to your allowlist can assist:
1. https://*.npg.io (any subdomain of npg.io)
2. https://dd4t.dadesktop.com - Steer clear of large downloads or uploads while the course is underway—for instance, pause system updates on Windows, Mac, or Linux until afterwards.
-
Your internet speed should exceed 10 Mbps download & 1 Mbps upload.
