One v3 cam having problems staying online

I have 6 v3 cams on the outside of my house. Very rarely do the other 5 have problems, but the driveway cam, the first one I bought, will be offline at least once a day.

Same firmware, signal strength shows 3 bars. Thought it was maybe the signal, but there is one maybe a foot away facing the other direction.

Should I just buy a new one? I don’t know what it could be.
