netsh wlan profiles
Sounds to me that your pc is connecting to a nearby open wireless access access point automatically but is not getting all of the correct settings from the device.
open a command prompt and enter:-
netsh wlan show profiles<Enter>
### looks like this
C: \Users\jim\Documents>netsh wlan show profiles
Profiles on interface Wireless Network Connection:
Group policy profiles (read only)
---------------------------------
<None>
User profiles
-------------
All User Profile : AndroidAP
###
The profile names are the wireless SSID's that have been saved on your PC.
Then delete any User profiles you are not using.
One of them is likely set to autoconnect to BTOpenzone or some such.
e.g. netsh wlan delete profile name="AndroidAP"
I have not tested the last command since I do not particularly want to delete the profile on my PC.
