I have a customer we fitted a route 10 and access points a while ago on his BT busness brandband and managed with the cloud controller the pppoe connection with BT dropped out some point over night annolying I’m on an island till tomorrow, so can’t phycaly get on site till I’m back on the main land.
Is there anyway to change the pppoe details on the route 10 localy with out it being connected to the internet and talking to the controller?
Yes, the easiest way to reconfigure it is to do a power-on-reset by holding down the reset button while applying power (https://help.alta.inc/hc/en-us/articles/41370872297371-Firmware-Bootstrapping-A-K-A-Power-on-Reset).
Then either use a browser (usually easier) or the mobile app to bring it back online, and once the Set up button shows back up in the controller, you can click that and it will pick up its old config (minus whatever was entered during the setup wizard).
