Three settings decide how well your Usenet downloads run: the server, the port and the number of connections. Here is what to use.
Ports: use 563 with SSL
| Port | Encrypted? | When to use it |
|---|---|---|
| 563 | Yes (SSL/TLS) | The standard choice. Use this. |
| 443 | Yes (SSL/TLS) | If 563 is blocked on your network (some workplaces and hotels) |
| 119 | No | Avoid. Anyone on the network path can see what you download. |
Most providers support 563 and 443 for SSL. Check your provider’s help page for its exact ports.
How many connections?
Each connection downloads a different piece at the same time. More connections help, up to a point:
- Up to 100 Mbps broadband: 10 to 20 connections
- 100 to 500 Mbps: 20 to 40 connections
- Gigabit: 40 to 60 connections, if your plan allows
Never set more than your plan allows. If you use the same account on two devices at once, they share the limit.
Fixing common problems
- Login failed: retype the username and password, and check the server address. Many providers use a different login for Usenet than for their website.
- Slow downloads: try more connections, or a server address closer to you (EU or US).
- “Too many connections”: lower the number, and close other Usenet apps using the same account.
- Can’t connect at all: try port 443 instead of 563.
