Read f*&^#% manual.
Dark blue means 3G connection. It shows when 3G connection is made but (usually) no data is transfered.
Ligh blue: modem is negotiating HS(?)PA or HSPA+ data transfer.
It indicate that some background programs on your PC start transfering data.

I should've made myself a bit more clear.
WHILE USING THE MODEM and DOING a SPEEDTEST I get those colours.
Via MR3020 about 0.4Mbps down and
Via USB about 1.2Mbps
Thx, I will do a test again on Monday, Maybe my modem is on GPRS or EDGE but the green LED is already on week-end having a dop!
UPDATE: next morning
Believe it or not, in my new office I have a spot (sphere) with a radius of about 2.5 cm EXACTLY where the USB port is located. If I move the Router (actually turn the MR3020) so that it falls within that spot, the light IMMEDIATELY turns "Light Blue" the moment I move it as much as 10cm's away it drops down in speed and is lit with the "Dark Blue"
I have now done this a few times and can produce this every time.
I carry on working on the Internet for probably an hour with a solid "Dark Blue" LED with horrendous speeds, If I move the router to that tiny little spot it turns "Light Blue" with 4 to 5 times the speed.
Can I really have such a tiny little HSPA+ spot??
Lastly, if you don't believe me, feel free. I'm sitting right next to this set-up and I'm not believing this either.
Conclusion: It's a signal issue and not a setting that I missed on the router.
PS. Awesome little router though, I suggest you head over to
dbg.co.za and check them out.
