Abstract: A wireless router receives a firmware update from a remote server, and destructively overwrites router firmware in flash memory in a chunk-wise manner, and then writes a kernel memory before going live with upgraded firmware. Some routers authenticate the firmware image. In some cases, image chunks are reordered into an executable order after receipt and before finishing their final arrangement in the flash memory. In some routers, a maximum firmware image size is at least two chunk sizes smaller than the flash memory storage capacity. Some routers remap ROM to RAM memory. Some decompress data from flash into a RAM. Some save text file configuration settings in flash before rebooting. Some detect a user's inactive billing status and redirect a web browser to a billing activation page.

Abstract: The inventive methodology provides an integrated plug and play solution designed to protect home networks against spam, phishing emails, viruses, spyware as well as other similar threats. The described content filtering appliance can be used for processing of web and email traffic implemented and can be deployed as a stand-alone appliance. In one implementation, the content processing appliance utilizes backend content filtering provided by a remote scanning service accessed via a network. The system employs network level analysis and translation of content and executes various procedures to handle the network traffic. In an embodiment of the invention, the appliance is provided with an automatic remote updating capability, wherein the software and data used by the appliance can be updated remotely via a network. Finally, the appliance may also implement parental controls.
