  1. I'm having this issue and haven't been able to correct. I've changed the IP range (they were both on 10.0.1. And the settings mentioned above. I am able to connect directly with an Ethernet cable and it will allow the connection when I disconnect from Ethernet and go to wireless. The issue is on initial sign in and it seems to have the error so fast it's like it's getting blocked at the router level before it has a chance to sign in.
