Single Network Adapter Dual Sub-Network Hotspot Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless access point systems require two network adapters, which is a limitation for conventional personal computers and laptops, as they typically only have one network adapter, making it difficult to set up and operate wireless hotspots for guest access.
Innovation Solution
A method and apparatus that utilize a single network adapter to operate on two different sub-networks by setting up distinct network addresses and routing tables, with the adapter configured as a hotspot controller to manage access and authenticate users, allowing the adapter to act as a gateway between sub-networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two network adapters are used on the wireless access point controller, then the system can connect to both modem and base station simultaneously, but the requirement for two network adapters makes it difficult to commission conventional wireless access points on standard personal computers and laptops
Solution Approach 1:
The patent makes a single network adapter perform multiple functions by enabling it to operate on two different sub-networks simultaneously. The adapter configures itself with two distinct IP addresses and routing tables, allowing it to function both as a client on the wireless network and as a gateway to the wired network, eliminating the need for separate network adapters.
Solution Approach 2:
The patent resolves the contradiction by adding a dimensional aspect to the network adapter's operation - it operates across two different network layers or dimensions (wireless sub-network and wired sub-network) simultaneously. This is achieved through multi-homing capability where the single adapter maintains connections to both networks by configuring multiple IP addresses and routing tables within the same network interface.
2Ease of manufacture
If a single network adapter operates on two different sub-networks, then conventional personal computers can be used to set up wireless hotspots, but the adapter must manage complex routing and access control between networks
Solution Approach 1:
The patent implements self-service by enabling the single network adapter to automatically configure itself for dual sub-network operation. The adapter autonomously sets up two different IP addresses, configures routing tables for both networks, and manages packet forwarding between the wireless and wired networks without requiring manual intervention or additional hardware components.
Solution Approach 2:
The single network adapter acts as an intermediary between the two sub-networks. It receives packets from one network, processes them through routing logic, and forwards them to the appropriate destination network. The adapter mediates traffic flow, performs address translation when necessary, and controls access between networks through its routing table configuration.

AI summary
A method is described for operating a single network adapter for use on two different sub-networks of the same type, and a corresponding apparatus. The method comprises setting up a first network address and routing table in the network adapter for use in the first sub-network; setting up a second network address and routing table in the network adapter for use in the second sub-network; receiving data for one of the first and second sub networks, and re-transmitting the data to the other of the first and second sub-network, using the network addresses and routing tables.
