You must not change any timezone related settings in the router. Time on routers must always be GMT / UTC +00:00 with DST off, regardless of your local time zone.
If you accidentally changed these settings please set it back, otherwise your clients won’t get the appropriate time period that they paid for. The router has to be synced to our radius servers.
For DDWRT do to one of the following:
1. Go to "Setup" menu, "Basic" tab
2.a set Time Zone / Summer Time (DST) > UTC / none
Use local time > NO (unchecked)
2.b in other models set as screenshot indicates below:
3. Make sure you "save", "apply" configuration and also to reboot the device.
If you have this setting but your router is still getting wrong time information, then maybe it is not getting the right time information from the time servers.
(IMPORTANT NOTE: This page describes how to set your local time zone, but remember that you need to set the GMT time on the router, not your local time!!! Check the GMT time here, if you see the same in the router, then you are done! )
NOTE #1: After you update the time information, you have to wait until the router sends a life signals again to our servers. It is sending life singals in every hour so within an hour the message should disappear.
Your local timezone and DST setting should always be set in the Control Center ( Manage > Locations > click on name > find Local time > Change the time by clicking on “change” next to “Local Time:”
