Piso WiFi Rates Reverted After Reboot

Part of the Troubleshooting pillar. Related guides in this category: Admin Page Will Not Save and WiFi Name Changed After Reset.

Rates that revert after a reboot are different from rates that change after an update, and different from rates that were never set correctly in the first place. A reboot reversion means the machine was showing the correct rates, then after a restart it shows older rates, default rates, or a mix of old and new rates. That pattern points to a save, storage, or profile problem, not to a customer error.

This post is mainly for operators, with a short customer section at the start. Customers should not change rates themselves. If you are a customer and the rates look wrong after a machine restart, report it with the proof below and do not pay until the operator confirms the correct rates.

Customer Symptom Check: What to Do First

If you are a customer and the rate sign no longer matches the portal:

1. Do not pay until the operator confirms the correct rates. A payment at the wrong rate can create a session that is hard to correct later.
2. Note the rate sign amount, the portal rate amount, the machine location, and the time, with a screenshot of the portal if you can take one safely.
3. Tell the operator whether the machine restarted, lost power, or was updated just before you noticed the change, if you know.
4. Do not try to fix rates by paying in a different mode, such as coin instead of voucher, unless the operator asks you to test it, because a mode change can hide the original fault.

Likely Causes, in Order, for Operators

Cause 1: Change saved in the portal, but not saved to storage

Some platforms require a save step, a confirm step, or a reboot prompt after a rate change. If the operator closed the admin page, lost connection, or rebooted before the save completed, the change may have been visible in the session but not written to storage. After a reboot, the machine loads the last saved rates, which are the old rates.

Cause 2: Failing storage, such as a failing microSD card

Small board machines often store settings on a microSD card. A failing card can appear to save a change, then lose it on reboot, or return a mix of old and new settings. This is the same storage fault described in the Admin Page Loads but Will Not Save guide, but here the symptom is reversion after a reboot, not a visible save error. Back up settings before changing them again, and check the card and backup feature for your platform.

Cause 3: Wrong profile, mode, or machine

Rates can differ by mode, such as coin mode versus voucher mode, or by profile, such as a weekday profile versus a promo profile. If a reboot loads a different profile or mode than the one you edited, the rates will look reverted, even though the edited rates still exist in another profile. Check that you edited the rate table for the mode and profile customers actually use.

Cause 4: Backup restore or firmware rollback after a fault

If a machine restored settings from an older backup after a fault, or rolled back firmware after a failed update, rates from the backup or rollback version will replace newer rates. Check the backup date, version, and update log before re-entering rates, or you may re-enter rates that will be overwritten again by the same restore.

Cause 5: Multiple machines or access points with different rates

If customers see different rates at different times, they may be connecting to different machines, access points, or repeaters with different rate tables. Confirm the machine location and WiFi name, and check that all units in a multi-machine setup use the same current rate table, or clearly different tables by design.

Operator Fix Order, Labelled as Operator Only

Work in this order, and test after each step. Do not re-enter rates repeatedly without finding why they reverted, because each failed save can leave the machine in a mixed state.

1. Note the current rates shown, the rates you expected, the platform, version, and the time of the last reboot, update, or power cut.
2. Back up settings if the panel still allows it, and note the licence key and version, before you change anything else.
3. Check the rate table for the correct mode and profile: coin mode, voucher mode, and any promo or profile that customers actually use. Correct the table in the right place, not in a profile customers never see.
4. Save, then follow any reboot prompt from the platform. Some platforms apply changes immediately, others prompt for a reboot. If a change does not take effect after save and, where prompted, reboot, stop and check storage before changing rates again.
5. Check storage: card health, backup feature, and whether other settings, such as WiFi name, pause settings, or portal settings, also reverted. If several settings reverted together, storage is more likely than a single rate typo.
6. Check backup and update history: backup date, firmware version, and whether a restore or rollback happened. If a restore is the cause, re-enter rates after the restore is complete, not before.
7. Test as a customer with a small payment, in each mode customers use, then reboot the machine once more and test again. Only reopen to customers when the rates survive a reboot and match the sign.
8. Update the sign if rates have legitimately changed, so customers do not pay at an old rate shown on an outdated sign.

What Counts as Proof, for Customers and Operators

For a customer report, include: machine location and WiFi name, rate sign amount, portal rate amount, time noticed, and whether a restart, power cut, or update happened just before. For an operator record, include: platform and version, rate table before and after, mode and profile edited, save and reboot steps taken, storage check result, backup date, and test payment result after a reboot. Keep that record privately, not on the machine sign.

Prevention

For operators, prevention is a save and reboot test habit: after any rate change, save, follow the reboot prompt if given, reboot once more, and test as a customer before reopening. Keep a written rate record, with date, mode, profile, and sign version, stored privately. Back up settings regularly, and replace a failing storage card through the supplier’s official path before it causes a wider settings loss. For customers, prevention is simpler: check the portal rate against the sign before you pay, especially after a machine restart or power cut, and report a mismatch before paying.

Frequently Asked Questions About Rates Reverting After a Reboot

I set new rates, but after a reboot the old rates are back. Did I set them wrong?

Not necessarily. You may have edited the wrong mode or profile, saved incompletely, or lost the save to a storage fault. Check mode and profile first, then save and reboot test, then storage, in that order, before re-entering rates again.

Why do only some rates revert, while others stay?

A mixed reversion points to a profile, mode, or partial save problem, or to a storage fault that kept some settings and lost others. Note exactly which rates reverted and which stayed, because that pattern helps the supplier diagnose the fault.

Is a reboot reversion the same as a factory reset?

No. A factory reset wipes WiFi name, passwords, rates, vouchers, and other settings to defaults. A reboot reversion usually returns rates to an older saved version, while other settings may stay. If WiFi name, passwords, and vouchers also reverted to defaults, check the WiFi Name Changed After a Reset guide, because a reset or fallback may have happened.

Should I keep re-entering rates until they stick?

No. Repeated re-entry without a save, storage, and reboot test can leave the machine in a mixed state and hide the cause. Stop after the first failed re-entry, check storage and backup history, and test with a small payment after a reboot.

Can a power cut cause rates to revert?

Yes, if a rate change was not yet saved to storage when power was lost, or if storage was already failing. A power cut alone should not revert rates that were saved and tested after a reboot. If saved rates revert after every power cut, storage is the likely cause.

As a customer, should I pay at the reverted rate or the sign rate?

Pay at neither until the operator confirms the correct rate. A payment at a wrong rate can create a session that is hard to correct, and it does not prove which rate was intended. Report the mismatch with the sign and portal amounts and the time.
