If for any reason the speed on Tweaknews (Usenet) suddenly slows down, it might be resolved by taking a number of simple steps:

1. Set the maximum number of threads permitted depending on your subscription.
2. If the connection goes by port 119, try port 563.
3. Turn off all firewalls or set them up so that they do not filter or block Usenet traffic.
4. Try a different news client. Grabit, for example, can run more slowly than NewsLeecher from time to time.

If none of these things helps, contact your Internet provider and ask whether Usenet traffic is restricted on port 119 and 563. If so, try port 443.
