Knowing how to change automatic pet feeder wifi network settings after a router upgrade, SSID rename, or password change starts with using the exact in-app network-switch menu for your model rather than pressing the hardware reset button. In-app network replacement and factory resetting are different operations: a reset can wipe device pairing or schedules, while an in-app switch updates the router connection under the model's specific frequency-band and location rules.

Below, we compare three official PETLIBRO support procedures—Granary 2, Polar Wet Food Feeder, and Granary 2 Vision—and show how to verify clock time, meal schedules, and actual bowl delivery after reconnecting.

Route your exact feeder model before opening Wi-Fi settings

When looking up how to change automatic pet feeder WiFi network connections, never borrow a menu label or frequency-band rule from another model:

Exact PETLIBRO model & official sourceExact in-app menu control nameDocumented frequency band & location conditionUnstated details (do not assume or extrapolate)
PETLIBRO Granary 2 (Granary 2 FAQ index → How do I replace the Wi-Fi?)Device Settings → Wi-Fi Settings → Replace Wi-FiArticle states the phone should be connected to the intended 2.4 GHz or 5 GHz network before starting the in-app replacementDoes not establish that every feeder carrying the Granary name supports dual-band Wi-Fi; does not state whether the page's reset fallback preserves saved time and meal schedules
PETLIBRO Polar Wet Food Feeder (Polar Replace WiFi guide)App WiFi Settings → Replace WiFi → WiFi icon → NextExplicitly requires the new Wi-Fi network to be in the same area as the old network and to operate only on the 2.4G bandDoes not establish a remote switch procedure if the feeder has already been moved out of range of the original area
PETLIBRO Granary 2 Vision (Vision FAQ index → How to change your Wi-Fi network?)Device Settings → WIFI Settings → Switch Wi-FiCovers a changed home Wi-Fi network or a feeder moved to a new location via the in-app Switch Wi-Fi pathFrequency band (2.4 GHz vs. 5 GHz) and reset behavior are unstated on this Vision page—never fill them in from Granary 2 or Polar

Follow the documented procedure for your exact model

Check that your app screen displays the exact control named for your feeder; if the menu differs, stop rather than triggering a factory reset:

PETLIBRO Granary 2: use the "Replace Wi-Fi" path

In the PETLIBRO Granary 2 support index and its linked How do I replace the Wi-Fi? article, changing the network for a PETLIBRO Granary 2 starts inside the app without resetting the hardware:

  1. Open your PETLIBRO Granary 2 device settings, tap Wi-Fi settings, and select Replace Wi-Fi.
  2. Follow the on-screen connection prompts (the Granary 2 article states that your phone should be connected to the target 2.4 GHz or 5 GHz network).
  3. Confirm the Wi-Fi network name and password, then wait for the Granary 2 to reconnect.

Keep that phone-network wording scoped strictly to this Granary 2 article rather than assuming all PETLIBRO feeders support 5 GHz. Although the same page mentions a reset-and-re-add fallback if replacement fails, we do not recommend using a reset as a shortcut because the page does not state what happens to your stored clock and feeding schedule during a reset.

PETLIBRO Polar Wet Food Feeder: respect the same-area, 2.4G-only condition

According to PETLIBRO's Polar Wet Food Feeder Wi-Fi replacement guide, you can replace the connected Wi-Fi in the app only when the new network is in the same area as the previous network and runs on the 2.4G band only. Within that Polar Wet Food Feeder scope, open the app's WiFi settings, tap Replace WiFi, tap the WiFi icon to pick the new 2.4G network, tap Next, and enter the new SSID and password.

PETLIBRO Granary 2 Vision: use the "Switch Wi-Fi" path

The PETLIBRO Granary 2 Vision support index links to How to change your Wi-Fi network? for a changed home router or a relocated Granary 2 Vision feeder. On the PETLIBRO Granary 2 Vision, open the device's Settings, select WIFI settings, and tap Switch Wi-Fi, then select the new network and follow the prompts until reconnection completes. Because this Vision article does not specify a frequency band or a reset step, keep both unstated rather than borrowing rules from Granary 2 or Polar.

Verify clock time, saved schedule, and bowl delivery after reconnecting

Seeing "Online" or "Connected" in the app only confirms network communication; it never proves that the feeder's internal clock, portion schedule, or physical rotor output is ready. Complete this four-item check after any Wi-Fi change (and if the router change involved a power outage, run our feeder power-interruption check as well):

Post-switch checkpointWhat to verify before leaving the pet relying on the feeder
1. App connection stateConfirm the exact model shows online under the new router SSID (log any error text if connection fails): ____
2. Device clock & time zoneVerify the feeder's current time and AM/PM setting match your local clock: ____
3. Saved feeding scheduleOpen the meal plan list and confirm every scheduled feeding time, portion count, and active toggle remained intact: ____
4. Next scheduled bowl checkObserve the physical bowl at the next scheduled meal (do not trigger endless manual feedings just to test Wi-Fi): ____

When comparing models in automatic pet feeders, always check the exact unit's Wi-Fi band requirements and app menu documentation before purchase.
