We recommend that you update your Linksys router firmware only if you are experiencing problems with it or require certain additional functionalities. We strongly recommend that you update the firmware of the router using a wired connection because doing it wirelessly risks interruption that could harm your router Lastly, you need a computer.Any computer would do as long as it has an ethernet port and has a recent version of any web browser installed Once you have gathered all the requirements you are now ready to update the Linksys router firmware The default IP address of most Linksys routers is 192.168.1.1 and the default username and password are both admin.Linksys did not return a request to confirm or comment on the reports. Johannes Ullrich, chief research officer with the SANS Institute, told The Reg that in addition to updating firmware, owners and administrators of the vulnerable routers should look to tighten their administrator access controls."They should either turn off remote admin functionality, or restrict it to IP addresses from which they need to access the router if they can," Ullrich said.Once you are in, you should take note of your wireless router settings.You would need this later as you reconfigure your router Click/tap the start upgrade button.
SANS noted that E1200 routers with the latest 2.0.06 firmware version seemed to be immune to the spotted attacks, but the E1000s – which are no longer supported – were not, even with the most recent firmware installed.
Your router’s firmware is basically the operating system that is specifically designed to run on your specific make and model of router (unless you are using a multi-router compatible open source firmware such as DD-WRT).
Usually, your router manufacturer will provide firmware updates for your specific make and model of router, via their website, or via a tool within the administrative console of your router (typically accessible via a web browser).
The report comes not long after word surfaced of other security vulnerabilities found in routers made by Linksys' former parent company, Cisco.
Those flaws affected a number of small business products from Cisco, and did not impact any Linksys branded devices.
