Every time we are going to connect to a new client, we have to turn the A6 power off and power on so that the C6X can connect. This is not supposed to be normal.
It is also happening to us. Horrible product so far
I have not seen the client fail to connect, but I have seen the client connect without showing up anywhere on the A6 as a registered client. Rebooting the A6 corrected this.
The need to reboot the AP to associate clients is a timing problem due to the distance of your clients from the AP. It will be resolved in the next release due shortly.
Do you have random disconnection when trying to push data through the link? As well as unstable ping and lag spike?
