The cloud service, which among other things allows users of some Wi-Fi home routers to manage their devices from away from home, went live last week and was included in an automatic firmware update to those routers. That brought a flood of complaints to online forums about both the firmware update and the privacy document, which said Cisco might track and share information about customers' Internet use and other data.
"We removed content that could have been misinterpreted as being inconsistent with Cisco's privacy statement based on a selective analysis," Cisco said in a statement.
"In a nutshell, this was just a mistake," Cisco spokesman David McCulloch said.
Some users of the Linksys EA3500 and EA4500 routers wrote on online forums last week that Cisco apparently had updated the firmware on their routers automatically without their consent. The new firmware prompted them to start managing their routers through the Cisco Connect Cloud service, which administers a router over the Internet instead of directly over the wireless LAN. Some users said they weren't able to keep managing their routers locally except through a limited interface that lacked features they were used to.
The updated privacy supplement for the cloud service says, "Cisco may collect and store detailed information regarding your network configuration and usage for the purpose of providing you technical networking support." It says that data will be associated with the customer only when he or she provides an ID number, randomly generated and under the user's control, to the support representative.
An administrator on the Cisco Home Community forum subsequently posted a link to instructions for downgrading the routers' firmware and opting out of future automatic upgrades.
But Cisco also responded to the complaints with a dedicated post to its official blog on Friday.
