@WMConey try to describe your solution a little better. do you have a pc as a controller?, check the firewall on the pc, check that the network card is not set to public but private. turn off...

@WMConey Do you only have one router on the controller or do you have multiple devices? Is the same problem with the other devices?

@WMConey Have you tried restarting the router?

@127.0.0.2 I don't think you can use CLI when the switch is connected to a controller, CLI has limited capabilities then. Reset switch to factory default and readopt is probably the only option.

@Czega I created over 1000 VLAN. so you have to use switch only :-)

@Czega If you use switch only, you can create multiple VLANs. I created 512 VLAN
