Connected to wifi but cant get on the internet

Tell us what device you are using and how you are trying to connect to the internet. If WIFI, try turning off WIFI then back on

Can you elaborate more on the type of device you are trying to connect to your WiFi or if every WiFi device you have is experiencing issues connecting to the internet?

Via WIFI or data connection, if WIFI check security key is in put correctly, turn off phone and WIFI unit, wait a couple of minutes and try again

If you're seeing the WiFi but cant connect to it try using a different type of security like WEP OR WPA.

If you cant see the WiFi at all try to use a range extender. The treadmill might be too far away from the router.

if you have no wifi ..... unless you also have an additional way to connect to the internet. google will not work... for example on my phone i can use wifi for internet or i can use my sim card and mobile data ....... i would suggest you fix your wifi problem 1st ... post more details ....il help if i can

your lumia 800 is ok and working fine. there is problem with your internet connection or your wifi modem. your modem's internet setting may have been altered by someone by mistake. your pppoe user name and password may have been deleted. when you will connect wifi to your lumia, then sometimes it will automatically start internet connectivity test. if this test passes then your internet will work fine, if it loses then you cannot use internet.

Try resetting the wifi connection and ensure that the source of the wifi is functioning properly, you may need to input the wifi password again for ensured connection.

ofcourse it requires wireless internet connection, when there are no wifi signals you cant use it

when going wifi
you have to go to internet connections or options in the control panel and click on the LAN settings button
the wifi modem will have a security code on the back and the wifi connection area code
click on the found area code on the back of the modem then enter the security code

I really do not understand your problem or question.
If you can not connect to the internet, or you do not have access to your networking thru your wifi connections, you will have to bwe more detailed for anyone to provide help.
