Hi lopez101, welcome to 7F!
strollin, offers a good suggestion.
It could also be, your devices may have lost their Security Key's (case sensitive) which the reboot may fix.
If not you will have to go into your wi-fi router settings and find it. Then enter it, into the appropriate setting on your devices.
Our wi-fi router has a 16 character alphanumeric key.
I would offer more insight, but we will need to know what devices, and router you are working with.
Is it all three or just the iphone?
