Good instincts from and — those are the two directions to try first (clear the saved profile and make sure the phone is using DHCP). The common failure after turning a static IP off is that the phone ends up either still using an incomplete manual configuration or it can’t get a DHCP lease from the router; when DHCP fails the device can self‑assign a 169.254.x.x (APIPA) address and lose Internet access. (learn.microsoft.com)

Quick triage (Windows Phone/Lumia specifics): confirm the SSID is visible, then view the phone’s Wi‑Fi details to see the current IP. On Windows Phone you can press‑and‑hold the network to delete or edit the saved profile — forcing a fresh DHCP handshake often fixes stale settings. Forgetting and rejoining the network is a simple, effective step. (icomera.com)

Recommended sequence (do these in order):

  1. Soft restart the phone (power off/on or hold Power + Volume Down until it vibrates) to clear temporary state. (learn.microsoft.com)
  2. Forget the Wi‑Fi network, then scan and re‑join (enter the password again). (icomera.com)
  3. Reboot the router/modem and verify the router’s DHCP server is enabled and the address pool isn’t exhausted (check the router LAN/DHCP page). (learn.microsoft.com)
  4. Test the Lumia on a different hotspot (phone tether or public Wi‑Fi) to isolate phone vs router.
  5. If DHCP still fails, either reapply a correct static IP (pick an address outside the router’s DHCP range and enter proper gateway/DNS) or use the Windows Device Recovery/phone reset only as a last resort. (learn.microsoft.com)

If other devices work and the Lumia alone fails, check the router for MAC filtering, guest‑network isolation, or reserved address conflicts before erasing the phone. These checks close the loop between the simple fixes already suggested by and and the router‑side causes that commonly block DHCP. (learn.microsoft.com)

IP assignments are specific to each network, so ask the network admin of the network you are using what is required since not all are the same.
That said, if I change such a thing I may have to reboot then forget and re-join the networks.

Assuming your system still sees the SSID of the WiFi accesspoint, then you will need to change your network (WiFi) configuration to use DHCP to get a network address from the local router.
