Binary package hint: ppp
A mobile broadband connection is very slow (only 0.4–0.5 Mb/s) in Jaunty and Karmic, when the theoretical max. speed of the affected ISP's plan is 3.6 Mb/s (in practise the speed is about 3 Mb/s in Windows Vista).
To reproduce:
Download a Ubuntu iso-image from a random mirror. In Hardy download speed is 250–300 kB/s, which is a good five times faster than in Jaunty (about 60 kB/s).
The regression, performance issue related to download speed, which is at worst ten times slower on average compared to Windows OS's (40 kB/s vs. 400 kB/s). The extremely slow speed seems to be hardware independent (Nokia CS-15, Huawei e1552, Nokia cell phone 6220 classic, ...). Currently there is a Finnish discussions going on at

Probably these speed / network bandwidth issues are related only to one internet service provider called Sonera (TeliaSonera) in Finland. Nevertheless, last autumn the "HelpDesk" at Sonera did not comment this issue.
Interesting is that, when you download for example four Ubuntu distros in the same time, your download speed is approximately: 60 kB/s + 60 kB/s + 60 kB/s + 60 kB/s = 240 kB/s. When you cancel three of those downloads, you will continue with the "normal" Jaunty download speed that is surprisingly 60 kB/s. Some other day the individual download speed could be only about 40 kB/s.
