Darn, I wish I had a LG VX-6100 although internet probably is really slow even if it’s free…
If you have an LG VX-6100 (some older/newer models have it to):
Press “Menu”, then “0”, It should say “??????”, it is actally asking you for a serivce code. The service code will be “000000”.
Once in the service menu scroll to WAP Setting (or press “9”).
