Ask HN: how can WiFi captive portal web pages affect iOS hardware keyboards?

2 points

There are many reports [1] of this unsolved issue: external iOS keyboard (bluetooth or smart connector) works until authentication to some WiFi captive portals.

Theoretically speaking, how is this possible? Could a wifi access point send incorrect management frames that affect the hardware chip that handles both WiFi and Bluetooth on iDevices? Why would that affect non-bluetooth keyboards that are physically attached via Smart Connector?
