Please make sure that the SSID and Security Key you enter are correct. The case of SSID, security key, symbols and channel* must be exactly the same as your wireless router's settings. In addition, the Wi-Fi SD does not support captive portal hotspots, which will redirect to a login screen for authentication and payment.
*Transcend StoreJet Cloud (10K) will only support WLAN channel 1~11.
For instructions of changing the WLAN channel, please see your wireless router's user manual.
