Yes, Peter's right.

The best way forward is to assume you need to do the full cycle of
anything again, and once the context(s) that you want is(are)
connected, then reconfigure the IP addressing from scratch (either
using DHCP or otherwise manually configuring the settings you get back
from "WDS Get Current Settings". Don't assume anything, even if you
have a fixed IP now, it's not really worth it IMO.
