Improving Connection Performance

There are times when DaDesktop may warn you if your connection appears to have a 'latency' (delay) that is too slow to provide good performance.

In this case, please follow the steps below to try to improve your connection.

Steps to take

Use an Ethernet connection if possible, or if using Wi-Fi, take an internet speed test beforehand to check your speed, e.g., using speedtest.net
Stay as close to the wireless access point as you can. Prefer 5 GHz Wi-Fi over 2.4 GHz, as the 2.4 GHz band often delivers lower speeds and is more susceptible to interference than the 5 GHz band.
Switch off or disable any VPNs or proxies before joining the course
If possible, disable any security applications that could conflict with the network connection, as these can affect connection speed—i.e., latency sometimes.
Participants may wish to speak to their company IT support for assistance, especially if their network is impacted by content or network filtering etc.
Whitelisting the following domains can help:-
1. https://\*.npg.io (e.g., any host at .npg.io)
2. https://dd4t.dadesktop.com
Avoid making large downloads or uploads during the course; pause Windows, Mac, or Linux updates, if possible, until after the course
Internet speed should be faster than: "10 Mbps download & 1 Mbps upload"
