RBS50v2 won't connect

One day last week this satellite would not connect to the router.

It has been working fine for a long time.

I do see my other satellite with no problem.

I have reset it to defaults and even put the satellite right next to the router with no luck.

I hit the sync button and  eventually I do get a blue light so I guess it sees the router.

Still nothing.

I even got a new satellite and it didn't work either so its sounding like the router itself.

Does anyone have something else I can try.
