Sad news. The testing is now over because D-link DWM-156 HSDPA modem does not support 900MHz frequency networks that 90% of Finland is using.
In 900MHz it supports only EDGE speeds that go only up to 200kbps.
Full HSDPA (3G) speed is only supported on 2100MHz frequency that is used only in some large citys.
The shop where i bought this did not mention anything about this. The package of manuals that come with DWM-156 do not mention anything about this.
The only place where i found this information was in website of D-link finland. There was one datasheet in english where it states the following.
GSM / GPRS / EDGE works in 850 / 900 / 1900 MHz
HSDPA works in 850 / 1900 / 2100 Mhz
Here is a link to that datasheet:
ftp://ftp.dlink.eu/datasheets/DWM-156.pdfI'm going to send this DWM-156 back to the shop and get my money back.
Sadly all D-link HSDPA modems seem to have this same flaw. So they all are just useless in Finland.
Before i send this baby back to the shop i still need to try it on Shareport. Now i only tested it connected straight to my netbook.
