I run a DELL Latitude E4300, which also features a DELL Mobile HSDPA Modem DW5530 . I observe the same problems as stated above, but the problem is definitely caused by a faulty handling of special characters in Gnome's Network Manager. This report refers to a fresh Lucid (10.04 LTS) install with all updates available to date (30.09.2010).
I live in Austria and the ISP for my mobile broadband internet connection is usually A1. Since updating from Jaunty (9.04), where the modem worked like a charm, I never managed to connect to the Internet in Lucid, though all settings were double-checked to be identical. However, thanks to Google, I found an Austrian forum article (sorry, I've lost the link) stating, that this probably is a result of a mishandling of special characters in either the login and/or password by the Network Manager. And, indeed, the login of the A1 internet connection is “...@aplus.at”, please refer to e.g. [1]. To confirm this bug, I've installed an other SIM card, this time from T-Mobile Austria, and -- believe it or not -- it worked. As can be seen in [1], for this ISP neither the login nor the password shows special characters, hence I think, that the cause for this bug can be considered as confirmed. This also explains, why only very few people seem to have this problem.
