I saw some people talking on /r/jailbreak about this being a bug from previous jailbreak data which you probably carried over through a backup.
 
I had this problem but it went away eventually. Try rebooting.

I just rejailbroke my ipod 5g and set up as brand new and still got the wifi bug. I dont think it has anything to do with 8.1 but the jailbreak itself because when I was on stock 8.1 I never had this issue.

When you had this issue were you jailbroken?

I am jailbroken. I had this issue but it went away. I don't know much about it.
