In Australia, there are two main types of internet service providers (ISPs): those that own and operate their own network infrastructure, and those that resell access to other providers’ networks.

1. Network owners and operators: These ISPs have invested in building and maintaining their own network infrastructure. They have more control over the quality of service and can directly influence factors like speed, reliability, and network capacity. Examples include Telstra, Optus, and TPG (which owns iiNet and Internode).
2. Resellers: These ISPs purchase wholesale access to network infrastructure from the owners and operators, and then sell internet plans to consumers under their own brand. They have less control over the network’s performance, as they rely on the infrastructure of the network owners. Examples include Dodo, Exetel, and Leaptel.

In the case of Leaptel, as a reseller, their ability to improve your internet speed is limited. They can optimize their own systems and routing to ensure the best possible performance, but ultimately, they are dependent on the network infrastructure they lease from the network owners.

However, resellers like Leaptel can still influence your internet experience by:

1. Offering plans with different speed tiers and data allowances
2. Providing good customer support
3. Optimizing their own network routing and systems
4. Choosing to resell access from network owners with better infrastructure in your area

In summary, while resellers like Leaptel have some influence over your internet experience, they are limited by the network infrastructure they lease from network owners and operators.
