I made a biggest mistake ever. Tried to upgrade a perfectly working RB433AH on distant node from 4.17 to 5.2 because of some reason after upgrading to 4.17 our cacti wireless signal graphs stopped working. The node is pretty far. Is this some common issue or just mine ? Does any experienced the same result ? Thanks.
Update: router does not have any wireless interfaces, just ethernet vlans. Upgraded via ftp.
