Wireless Settings


If you are a registered patron, you can access Wi-Fi everywhere in the building and in the park (NTK 3 entrance) and also at the plaza (NTK 1 entrance).


Wireless name (SSID): NTK-Simple
Encryption: None
Connectivity: WiFi; IPv4; NAT; no proxy
Blocked ports: 25 (SMTP)

Use your NTK customer username and password when prompted.


Wireless name (SSID): eduroam

Use your Eduroam login, see information about your Eduroam:


I can't see the NTK-Simple network on my list.

Your adapter probably only supports the Wi-Fi protocol 802.11b, which the library doesn't support because it's unstable and slow.

I can see the network, but can't connect.

You probably have a fixed IP address. In Windows, open Control Panel \ Network and Internet \ Network Connections and Features WiFi adapter-> IPv4 (or IPv6) and make sure  you have selected the option "Obtain an IP address from the DHCP server automatically".

I can connect to the network, but Skype, chat, etc., aren't working.

Open your web browser and enter any page. This will redirect to the library login form. After you successfully authenticate, you'll be able to access those services.

I can connect to the network, but I can't see the login form.

Type into the address bar of your browser.

After I submit my username and password, I get the message: "Web Authentication Unsuccessful - Please wait"

You may have typed your username or password incorrectly. Try again, reset your password, or ask for your authentication credentials at a service desk.

I can connect to the network, but it goes in and out.

This problem is often found in netbooks when operating on battery. Wi-Fi adapter turns on power saving mode that reduces adapter power and the adapter is constantly trying to connect to a network that requires full power for its proper operation. In the Wi-Fi adapter configuration, see a feature that lets you turn off power saving mode when running on battery.

I cannot login to NTK-Simple with my iPhone or iPad (i.e., after I authenticate, nothing happens).

All pending updates on your device must be complete in order to log in successfully. Restart your device to ensure all pending updates are finished.
