Precisely I recently unlcoked my phone so I may have skipped something while setting up on the new network!
Did it ever work?
If it did then when did it stop?
Have you configured your internet settings properly?
Access point is really for tethering (accessing the internet from other devices - laptop, tablet etc. - using your phone as the "modem") so should not be required for accessing the internet from your phone directly.
Hope this helps.
Great - glad it helped. It's useful to get feedback from people about how they have solved their issues. Might help the next person.
