How do I update/patch my home router?
This is unfortunately can be one of the more difficult things for people to do, in part because there is no uniform answer. It depends on the router or WiFi access point you are using. My recommendation is to check the website of the manufacturer for your router, look up your particular router, and follow the manufacturer’s instructions. Newer routers can check for updates and install them, but older routers may require you to download new software - generally called “firmware” - and then install it. If you router is supplied by your ISP, then your ISP should have information about up to update the router, and you may be able to call customer support for help.
