Wifi without Password is an bad Idea nowadays
just my 2 cents.
Without dhcp server 169.254.20.x ist the default. Only local, no routing like 10.xxx or 192.168.xxx.
Do yourself an Favor and add an cheap little Wifi/Cell Router to your Setup, they take litte Current from you Batteries and you get much more Stability.
Raspberrys doubled as APs make often Trouble with instable Connects, these are difficult to localize. Since i added one all my Network Quircks are gone...
Good Luck - Holger
