1552H Mesh network (3 RAP, 13 MAP, 2504, Outdoor) dropped after 10 days working. Checked with WLC, 5GHz radio are down. RF2 LED of each RAP is off. Tried rebooting WLC and mesh was up for a while but drop again at the end. Only 3 RAP found in WLC.
Could somebody advise where to start to resolve the issue.
