Good day.
43 d’link DWL 6610 ap access points are connected through the d’link DGS 1510 28xmp switch and with the d’link DWC 2000 controller. After 2-3 months of operation, half of the access points gracefully stopped working one by one, only the Power indicator lights up red. We checked on another PoE switch, tried reset – without result.
Please help someone with what options. Thanks!
