After bad VLAn configuration I can not access ZF 7762 any more. I tried to return to factory default (shorten pin 3 &4)) but it didnt work. 192.168.0.1 is not accessible. Is there another way to return to factory default or to access AP?
Try connecting PC directly to factory defaulted AP (not thru switch with VLANs assigned). Then you may need to prep your AP before re-connecting it to the network.
If you made changes to the AP(s) switch port VLAN settings, Ruckus considers VLAN 1 to be untagged, which would match/recognize a 'native' VLAN connected AP.
If you changed your ZD's Configure/Access Points, Mgt VLAN from 1 to XX, the ZD expects all AP to ZD packets to come into the ZD switchport with a VLAN tag of XX. Hopefully, VLAN XX extends from your APs to the ZD.
If you now need to set the AP's management VLAN to match your switch access VLAN/PVID, you can connect directly and issue a configuration command. Use 'super/sp-admin' to log into a factory defaulted AP. View 'help set' to get a idea of the available commands. This is the one to change your AP to match a VLAN you specified under the ZD/Configure APs, AP Policies, Mgt VLAN.
rkscli: set mgmt-vlan XX
If you match this before reconnecting to the network, does that help it be seen by your ZD?
