Abstract

A portable router comprises a memory unit, a network sharing port, an operating/processing unit connecting with the two components. The memory unit has an original parameter configuration area and an updated parameter configuration area. An originally-configured network address and a prime DHCP server address range are built in the original parameter configuration area. The network sharing port has an external network connection port and an internal network connection port. The external network connection port implements connection with an external network having an external network address. The internal network connection port implements an internal network. The operating/processing unit retrieves the originally-configured network address and compares it with the external network address. When two addresses are identical, the operating/processing unit generates a new network address different from the external network address and a new DHCP server address range. When two addresses are different, the operating/processing unit directly adopts the originally-configured network address.

Claims

1. A portable router comprising

a memory unit including an original parameter configuration area and an updated parameter configuration area, wherein an originally-configured network address and a prime DHCP (Dynamic Host Configuration Protocol) server address range are built in said original parameter configuration area;

a network sharing port including an external network connection port and an internal network connection port, wherein said external network connection port enables said portable router to connect with an external network having an external network address, and wherein said internal network connection port connects with at least one Internet-access device to form an internal network; and

an operating/processing unit electrically connecting with said memory unit and said network sharing port, retrieving said originally-configured network address, comparing said originally-configured network address with said external network address, generating a new network address different from said external network address and a new DHCP server address range, and storing said new network address and said new DHCP server address range in said updated parameter configuration area for application of said internal network if said originally-configured network address and said external network address are in an identical subnet, and directly adopting said originally-configured network address if said originally-configured network address and said external network address are in different subnets.

2. The portable router according to claim 1, wherein said memory unit is a flash memory.

3. The portable router according to claim 1, wherein said memory unit includes a flash memory and an SDRAM (Synchronous Dynamic Random Access Memory), and wherein said original parameter configuration area is arranged on said flash memory, and wherein said updated parameter configuration area is arranged in a buffer area of said SDRAM.

4. The portable router according to claim 1 further comprising a wireless network communication module converting data of packets coming from said operating/processing unit into wireless signals.
