A request from a mobile access point that is installed on a vehicle may be received via network interface circuitry of one or more computing devices. Processing circuitry of the one or more computing devices may determine characteristics of a captive portal to present in response to the request based on current location of the vehicle and mobile access point. A captive portal with the determined characteristics is then provided by the processing circuitry, via the network interface circuitry, in response to the request.
