Google Nest does not make it easy to change Wi-Fi settings for cameras and doorbells. That's why their first recommendation is to set the network name (SSID) and password on a new router/modem to the same values used on your old router/modem. (That's what we did when we got a new router/modem, and we didn't have to do anything with our Google Nest cameras and doorbells.)
For some older Google Nest cameras and doorbells you can go to Settings | Home info | Home Wi-Fi help in the Google Nest app; if you have this option and your Dropcam is listed, you SHOULD be able to select Start | Update settings to update your camera's Wi-Fi settings (https://support.google.com/googlenest/answer/9223711?hl=en&sjid=16512504569667942426-NC#zippy=%2Cuse...).
If that's not possible, then you need to do a factory reset, but since the Dropcam, like the 1st gen Nest Cam Indoor and Nest Cam Outdoor, does not have a factory reset button, the only way to do a factory reset is to remove it from the Google Nest app while you are still on your old Wi-Fi network and your camera is still online (https://support.google.com/googlenest/answer/9252162?hl=en&sjid=16512504569667942426-NC#zippy=%2Cnes...).
Google Nest announced last April that it is discontinuing support for Dropcams on April 8, 2024 (https://www.googlenestcommunity.com/t5/Blog/An-update-for-our-Nest-Secure-Dropcam-and-Works-with-Nes...). Customers whose Dropcams were on a Nest Aware subscription for the month preceding the announcement were supposed to get a replacement offer.
