6. The portable device of claim 5 , further comprising:
a user interface for specifying either the first operation mode or the second operation mode as the operation mode of the first processing section, wherein
the second processing section is configured to detect connection to the router when connection of the main unit to the attachment unit is detected, when the function of the port selected at the switch is the function for connecting to the another device different from the client, and when the first operation mode is specified as the operation mode of the first processing section by the user interface, and
the second processing section is configured to detect disconnection from the router when disconnection of the main unit from the attachment unit is detected, when the function of the port selected at the switch is the function for connecting with the client, or when the second operation mode is specified as the operation mode of the first processing section by the user interface.
7. The portable device of claim 4 , further comprising:
a user interface for specifying either the first operation mode or the second operation mode as the operation mode of the first processing section, wherein
the second processing section is configured to detect connection of the portable device to the router when connection of the main unit to the attachment unit is detected and when the first operation mode is specified as the operation mode of the first processing section by the user interface, and
the second processing section is configured to detect disconnection of the portable device from the router when disconnection of the main unit from the attachment unit is detected or when the second operation mode is specified as the operation mode of the first processing section by the user interface.
8. The portable device of claim 2 , further comprising:
a wireless connection interface module configured to control a wireless connection with the router; and
a memory configured to store candidate profiles used for wireless connection with the router by the wireless connection interface module, wherein
the second processing section is configured to detect connection of the portable device to the router when the profile used by the wireless connection interface module is a specified profile out of the candidate profiles, and detect disconnection of the portable device from the router when the profile used by the wireless connection interface module is not the specified profile.
9. The portable device of claim 8 , wherein the profile includes at least an Extended Service Set Identifier (ESSID).
10. The portable device of claim 2 , further comprising:
a mobile communication network control module configured to control wireless communication in a mobile communication network.
11. A portable device configured to be connected to a router via a wireless or wired connection, the portable device comprising:
a first processing section configured to operate in each of a first operation mode to serve as a bridge functional part or a second operation mode to serve as a router functional part, wherein
the first processing section operates in the second operation mode when the portable device is disconnected from a router.
12. The portable device of claim 11 , further comprising:
a second processing section, wherein
the first processing section is configured to be set to either the first operation mode or the second operation mode and operates in the set operation mode;
the second processing section is configured to detect connection of the portable device to the router and disconnection of the portable device from the router; and
the first processing section is configured to set the operation mode to the second operation mode when disconnection of the portable device from the router is detected.
13. The portable device of claim 12 , wherein the first processing section is configured to set the operation mode to the first operation mode when connection of the portable device to the router is detected.
14. The portable device of claim 13 , comprising:
