Welcome to the Nokia Discussions Board!
Try to deactivate your mobile data by settings> cellular/mobile network> data connection. Reboot the phone (re-insert the simcard) and then turn on you data connection.
Let us know how you get on and feel free to post any other questions you may have.
We may have to call your network provider and ask for the APN settings and set it up manually on the phone. And to further isolate the case, we can try to connect to a different computer.
Sorry for the misunderstanding. I would rather have to perform a hard reset first before bringing the phone to Nokia Care. Syncing your data using the Zune software is highly recommended. Or you can check for SW updates as well using Zune. You can check this link for the steps on how to update your phone's software.
I discovered just now that i have lost my Wifi functionality on my lumia 800 too. when i switch on the functionality the phone apparently seems like it is searching for wifi connections but it doesnt detect any, including the default Wifi connection i use, even though the signal is strong. Seems i have lost both wifi detection as well as Internet sharing. A few days before i found all these problem, the phone out of the blue went into a cycle of back to back rebooting. I managed to stop it finally by manually switching off the phone as soon as it finished rebooting. The problems that i have now seem to have surfaced since this incident. What do i do now?
I have the same problem with my lumia 800,when I try to connect internet sharing I receive this message "CONNECTION NOT SHARED",I buy this phone from Vodafone Italy and I use in Vodafone Romania,I try everything what I read in forums(reset factory,network setup etc).
carrier :Vodafone SW variant ID212 v.05

If anybody have this probleme or answear,please help me!!!!!!!!!
Thank you for posting!
Do you have active data plan from your network provider? If yes, where you able to browse any websites using your phone?
Have you also verify from your network provider if they allow the tethering service?
Things that you can try:
1) Enable Data connection. Settings > Mobile network/Cellular > Data connection > On.
2) Disable the WiFi connection. Settings > WiFi > Off.
3) Activate Internet Sharing. Settings > Internet sharing > On.
I just receive the OS version:7.10.8862.144 update today and still nothing,yes I have a data plan network with tethering support becouse before this phone I have another with wp 7.5 and for this internet sharing working very very fine,I try all what you learn me to do and nothing...maybe because I buy this phone from vodafone Italy and I use it in Vodafone Romania?.I mentioned that the my internet connection works perfect.
Thank you again and heeelp please!!!!
