huawei e160 not working in 10.6

Disabling the PIN isn't the solution, I am afraid (at least not in every case).
I have a Huawei E169 3G USB modem, which refuses to work since I installed S.L.
No way to have it work with the phone carrier software (Tre Italia, in my case).
I shall try your suggestions about directly configuring the connection via "preferences" ASAP, and let you know if it works for me, too.

Under advanced, I unchecked enable error correction and compression, and unchecked send PPP packets.

Speed went from 100kbps to 800 kbps

Hi,

after updatding to Snow Leopard it happened the same to me, i followed the instructions posted above and it worked flawlessly i just had to enter my carrier's configuration as follows:

Carrier Telcel MX
telephone number *99#
account name "webgprs"
password "webgprs2002"

My parents just bought a MacBook running 10.6 in the UK. They have an E169 modem from '3' (Tre) in Italy (where they live). The installer on the modem stick fails immediately with an unexpected error every time you run it. However, they also had an E160 stick from the UK. The installer on that worked OK, and by:
- running the 3 Connect software from that E160 stick,
- but with the Italian E169 modem plugged in,
- and by putting in an APN of "tre.it" with a phone no of *99# and leaving the username and password blank it nearly works.

It finds a mobile signal OK and starts to connect but then fails with a PPP authentication error. Added complication is that they are not very tech literate and they are back in Italy now!

I've told them to try putting in a username and password of "null" (as advised here http://www.mactalk.com.au/2009/09/03/thursday-how-to-huawei-mobile-broadband-sno w-leopard/).

Anyone else managed to get the E169 working with tre.it and 10.6 please tell me how you did it! Thanks.

Harry, thanks, now works fine!!!
