default pre shared key

[PRES4]

In the security settings for my MI424WR router it recommends using the default pre shared key which is 1234567890ABCDEF. Is that a security risk? If everybody uses the same default key, they can all get into each other's network. The instructions didn't say anything else, so I must be missing something.

Thanks Preston

That key I believe is different from router to router. I believe it is also on the label that is attached to the router, so, you do not need to worry about someone else knowing it, unless you allow someone to see the label on your router.
