Nokia N800 detects WiFi networks but is unable to log-in/validate to access internet.

If your WiFi is ON then the station ID should be showing when you look for a wifi signal with your tablet.
You should configure the Access Point with a new password and then attempt to log in with that new password.
You may need to uninstall the driver for the wifi on your tablet and re-install it using a new driver.

Make sure the wifi/3g is turned on and connected to a network with internet access. You might need to refresh your router and modem as my Galaxy Tab sometimes gets messed up if I log on to another wifi network away from home. i.e. McDonalds/Pizza Hut etc. I may be connected to my wifi, but my tablet doesn't have a correct IP address if it has one at all. The internet speed can be a factor as games don't use a much bandwidth as apps like Google and Facebook.

Step 1Ensure the Wi-Fi and Low Power button located on the top of the device is not in the Off position. This will completely shut off your Wi-Fi adaptor and prevent you from connecting to the network.

Step 2Press the power button on the left side of the device and allow the Pandigital Novel to detect local network connections. If you can't find a local connection, you may be out of range and should move closer to the wireless router until the device detects the network.

Step 3Tap the name of the Wi-Fi network from the provided connection list. If the network has a lock icon next to the name, this means you will need the network security password to log in.

Step 4Enter the security password if prompted, and then tap "Connect."

Step 5Tap the "Next" button to reconnect to the Wi-Fi connection.

Step 6Tap the "Web" button from the main menu if you are attempting to connect to a public hotspot. This will launch the Web browser where you can enter any log in information required to obtain an Internet connection at the hot spot.

Please check your password and see the strength of the WI-Fi in your area. If this a wifi of your home wireless modem then check the modem and reset accordingly. switch off power for some time and restart.
If not check your tablet on another wifi to confirm this or if the configuration has gone off from the settings.
make sure that your password and the network is connected as seen on the lower taskbar .
