Quick update on this post. Still no resolution after hours and hours, multiple computers, multiple browsers, connection via Wi-Fi as well as direct, WireShark logs and Chrome debug’s. It is clear to me that this is a router problem, but we’ll keep chipping away it until Peplink comes to that conclusion. This is even more difficult to diagnose because it is on a yacht, so I have to remote in to setup tests then have a crew member connect direct to the Vlan port to run the test then back on the Lan for me to remote back in and retrieve files. This is very frustrating and I wonder how widespread this problem is and people just silently give up and do something else. And this thread on Captive Portal setup is NOT valid for the B305, you cannot setup SSID via IC2, it must be done via Web Admin or direct if you have access to the router: Configure Captive Portal in InControl2 - Knowledgebase / Tips and Tricks - Peplink Community
