Troubleshooting and Reconfiguring Home Network

The invention disclosure explains a simple mechanism to troubleshoot and reconfigure the home network when there is an unexpected change in the configuration of devices in the network. The proposed mechanism will help the end user to perform the initial troubleshooting of the fault and also will help in reducing the field call rates for Philips products

Home networks are getting complicated day by day with the addition of different flavours of devices to the network. Today's home network has a combination of Personal computing devices, mobiles devices, multimedia devices and the list grows.

With the mobile devices being a part of the home network, the network configuration of these mobile devices will keep changing as and when they move to different networks. There could also be instances were the network configurations of the personal computers are changed. This would lead to a situation were the devices in the home network are not able to find each other and able to access the data from each other.

Dynamic Host Configuration Protocol (DHCP) tries to address this issue to a certain extent but enabling the Router in the home to allocate the device its IP address dynamically. But there could be instances where the DHCP server in the router is down, when the device has a Static address allocated in it or any other similar situation where the device is not able to dynamically take an IP address. In such cases, the device will not be able to connect and share contents with other devices in the network.

The mechanism proposed in this invention disclosure for Troubleshooting and Reconfiguring the Home Network can be used for self diagnosis by home network devices and also can be used by the customer care engineer to troubleshoot the network fault. The proposed invention uses network protocols like ARP, RARP and InARP (Inverse ARP) to build and maintain a network information table of all devices in the network. This proposed mechanism can reduce the field call rates related to network faults as the consumer would get user-friendly messages on their device to explain the exact cause of the failures and tips on how to rectify the problem. In certain cases, the problem will automatically be rectified by this invention.

Each device will maintain a network information table with the applications it is interested in. This table should be updated by each troubleshooting sequence.

The Figure 1 shows a typical home network with Multimedia devices, mobile devices and the Personal computing devices connected together. All the devices connected to the network are accessible to each other when all are configured with unique IP addresses in the same subnet. For example, the IP address can range from to with the subnet address configured to

Following are some of the situations when the devices are NOT able to communicate to each other:
