NOOK says I have no WIFI do I need new Password

Nook is the reading Nook?if so try contacting the customer service and they should be able to direct you to how to get your Password changed.

Press and hold the wifi option and then search for the network, else turn off both the devices and restart the router first, let all the lights come up and then turn on the tablet.

A nook cannot be used as a phone.
Your Nook password is the same as your Barnes and Noble account.
You can reset your nook and start anew, but you risk losing everything you have saved.

you remember your password or stop buying things that need passwords

try turning off Wi Fi on glow book and then turn Wi Fi back on .
check you have the correct matching encryption method is it WPA2 or WPA1 or WEP may need to confirm it in router settings to be abslotely sure.

I assume you already have WiFi, if you don't, I suggest going out to wal-mart and buying a cheap wireless router to get you started. Then the instructions should explain how to get the password set up.
If you already have WiFi and the problem is that you forgot your password, then this should be able to be fixed easily if you know or have not changed the password for your WiFi router. Below is a set of steps to resolve the issue. The only requirement is a computer connected to the same router via WiFi or Ethernet.
1. Open Command Prompt (in windows) or open Terminal (in Mac OSX) 2. In the command line, enter "ipconfig" and press enter. 3. Look for Default Gateway and remember the corresponding IP Address. (Format: ###.###.###.###) It might look like 192.168.2.1 but not necessarily. 4. Remember that IP Address (write it down, copy it, do something). 5. Open your favorite web browser and enter that IP Address into the URL box. 6. This should ask you login, if it doesn't, skip step 7. 7. use the username that you set up the router with, or if you didn't change it, try using "admin" as the username and "admin" as the password. Try not using a password. If you still can't figure it out, use google to try and find the default password for your brand of router. 8. Once logged in, you can restore factory settings, or change your WiFi Password.

Having more information would have been helpful. (Aka - Router Brand, Is it your router, are any computers connected to it) Hope this was helpful.

From what I have found on this issue it looks like you will need to restore your nook back to factory settings. Any books you bought and backed up from Barnes & Nobles should re-download once you have restored the device and re-registered.

To complete a factory fallback:

1. Turn your device completely off.

2. Power up the device while holding in both the power button and the physical "n" button at the bottom of your NOOKcolor.

3. The device should begin to power up and you will see the welcome screen however keep holding both buttons down and the device will power down.

4. Repeat step 2.

5. When the welcome screen comes up, release both buttons.

6. The device will begin to power on and then a window will pop up asking if you would like to restore your device. Press the "n" button once and again to confirm.

7. The NOOKcolor will restore itself to full factory defaults and will startup as if it were brand new.

8. Re-register your device (while connected to a WiFi network) and you will start over fresh

In order to start using your Nook, you'll need to register it through the Barnes & Noble website - I've shared the steps below. Once you've registered it, you will be able to start purchasing and reading books. Please note that you will need to set-up a B&N.com account first. That is done on BN.com and simply click "new user account." Once you have set that up, follow the below Nook set-up steps.
NOOK Set-Up Steps

1. Charge your new NOOK 3G or NOOK Wi-Fi for 3-hours from a wall outlet using the Power Adapter and USB Cable packed at the bottom of your NOOK box.
2. Turn on your NOOK by pressing the power button at the top.
3. Connect to Wi-Fi.
4. Register your device by entering your BN.com account email.
5. Tap the down arrow button in the lower right corner of your color touchscreen.
6. Enter your BN.com password.
7. Tap Submit
