Keep Up on Encryption
There are several kinds of encryption built into routers, which gets a little confusing for those setting up a router for the first time. The current best standard is WPA2, which everyone should be using. If you aren’t sure what type of encryption you are using, check it out and make sure it’s set to WPA2 if necessary (this may require a change to your password).
On the other hand, you may be saying, “I’ve been using a router my whole life. I already know that I need WPA2.” In that case, watch out! WPA2 is actually a fairly old encryption standard at this point and the powers that be have been working on WPA3 for a few years now. It’s nearly ready to be released, and when it becomes available for your router, you will need to switch to it!
