Following on from my last post we now move to the other HSDPA card I bought. This is an Option GTM380. As I can tell its not OEM'd by anyone else like the HS2300/MC 8775 was. Option's web page was recently re-vamped and the IEMI for my card will now let me download the latest driver from Option.
You can also get the driver and software bundle from the Option AT&T support page here.
The interface is a fair bit more basic than the Sierra Watcher, but there is still all the things you need to get it working.
One thing that didn't work as I expected is that the "Autoconnect" option in the software doesnt seem to leave the card in the "Always On" state. You can go into the cards driver properties and change the Autoconnect and Auto re-connect variables to 1 which does the trick however the software client still tries to tear down the connection if you exit it. Luckily the auto-reconnect function in the driver brings the link back up.
This card has two antenna connections that are needed to support 7.2MBps, and if the weather is right you can get about 60% of that. Two antennas doesn't seem to buy much extra connectivity reliability over the MC 8775 card, however.
The one significant gripe I have with this card is its lack of compatibility with Windows, and specifically Windows 7. The card drivers fail to re-initialise after sleeping, which I would do regularly given that I commute with my laptop. The issue is covered and patched for Vista however I'm not running Vista anymore. I do hope that its fixed in later builds of 7 - I'm currently on 7077 x64.
