Hi Nokians,

After I have upgraded E71's firmware to 200.21.118, the GPS positioning server address is changed from

supl.nokia.com

to

h-slp.mnc016.mcc502.pub.3gppnetwork.org

Now my A-GPS not working. Previously, it took less than 1 minute to show my current position.

On another issue,  If I turn "assisted" off, GPS is not working as well -- not able to showmy current position.

200.21.118

Hi there

You can edit the positioning server by entering menu, tools, settings, general, positioning, positioning server, server address.

Change it to the supl.nokia.com and make sure the correct access point is selected. It must be a WEB and NOT a WAP access point. i.e there must be no proxy configuration on the access point selected.

Hope this helps you.

After fiddling around the GPS, and reading some posts here, my observation is as follows:-

•  If "assisted"  is off and indoor, satellite cannot be locked, so "Map" will not show "my position".

•  If "assisted" is off and indoor but close to door or window, satellite maybe (but take a long time) or may not be locked 

•  If "assisted" is off and I'm driving, satellite locking is about 5 minutes - 10 minutes.

Conclusion: best enable "assisted". Downside is, there GPRS/data charges by operator.

GPS signals are too weak to make it through most buildings, so your observations are not surprising.

I believe Assisted GPS using cell information to query a backend server to determine your approximate

location very quickly and then that helps the GPS to lock on faster. I've observed that a pure an simple

Garmin GPS can take 10 minutes or longer for initial lock, which makes Assisted GPS really attractive,

despite the additional cost.
