HELP! Can't get 3G on ZTE MF636 + Webee WiFi

I really need some help to get Saunalahti 3G Internet.  I have a white ZTE MF636 3G modem stick, and it works well if I open the connection program and choose "3G only".  I get about 2 Mbps, which is great.

But when I plug it into my Webee WiFi router, it only connects at 2G speeds (when in Auto mode - autoselect between 2G and 3G), when I know 3G is available.  On the 3.5G modem settings page, if I select "3G only", it never connects.  It just keeps a solid red LED light (I believe it means roaming).

What am I doing wrong?  Has anyone had this problem?  Can you help me set this up please?

My current connection settings for the 3.5G modem in the Webee:
APN: internet.saunalahti
login:
password:
mode: 3G only
PIN code: is disabled

Please please please help!  I want to share the Internet access between computers in the home.  Should I clone my mac address?  Or change something in the settings?

Thanks all!

One possible reason for only 2G-connection is the physical location of the stick. Although "Elisa 3G-network works everywhere" (acconrding to advertising  ;)), it´s sometimes very delicate of positioning the stick. Some says even millimetres counts but inches for sure.

Try MDMA program which can give better signal strength information. Change the physical location of the webee box so that the modem faces a window or use usb extension cord to bring the modem to a place where stronger signal is available. The router might not be 100% compatible with ZTE or might have a bug which might set modem to 2G instead of 3G only. 
Thanks for your replies - I don't believe this is a connectivity issue, as I've put the router literally on the window, centimeters away from where the modem worked fine in the laptop (5 bars for 3G signal) and in direct path of the 3G tower.

I think the problem is in old firmware of one of the two.  I have the latest Webee router firmis (daimler.fi), which added support of this particular modem, but I still can't get 3G to work.

Another guess I have is that this may be an issue of Elisa vs. Saunalahti?  When I connect on my laptop using a connection manager, it warns me that I am in "roaming mode" not on a partner network, although it is a saunalahti modem connecting to Elisa network (same network, right?).  The modem then works blazing fast.  But maybe the router has a problem with this perceived "roaming" and refuses to connect to a network it thinks is "alien".  Just a guess.

Sorry, but he is using ZTE which is NOT supported by MDMA.

As for Webee; having tested it briefly I can assure you it is a truly miserable piece of
cr... technology, I mean. It is by far the most unreliable 3G router I have tested.
It says it supports ZTE but it gets frozen at some point. The unit I tested also got
utterly hot and stopped working after some time, the reset button did not work at
that point, either.

I have so far tested three or four different routers and they all seem to fail when used
with certain 3G modems. Upgrading to a more recent  firmware will in many cases
lead to even less reliability. I have not yet found a router that works with ZTE and
I still have to use an old XP workstation as my route to the Internet (Windows Internet
Connection Sharing).

So: sorry to disappoint you but I do not think there is much to do to help you with your
selection of hardware.

As a side note: The Telewell router I had used with my E220 worked pretty well
but after the latest firmware upgrade I have experienced more problems than
before and my neighbour is telling me the same.
Thanks!  I know the mass retailers who rebrand a product, usually choose the cheapest one to keep costs down.

Webee has been on and running at my parents' summerhouse for over 6 months now, so I can't say anything negative about its reliability.  I don't have enough experience to make a judgement on the modem since I haven't really tried many, let alone compare them in action.

After fiddling some more with the router, changing Init strings and essentially resetting everything to 0, I noticed that I wasn't getting even a 2G signal in an obviously good spot.  That lead me to play with the router's location some more, and I finally got a blue light (3G!).  It's very unstable though.  Having read some forums early today (thank you, Google Translate!), I think I saw something about the modem possibly operating on lower power, thus decreasing its radio sensitivity.  Could be the case.

Anyhoo, thanks everyone!

I have had this suspicion for some time and I have been planning to perform a surgery on one of the shorter USB cables and measure the voltage/current using different modems I have but I will do that when I have the time for that.

ZTE is very probably one of the most power-hungry modems as it gets very hot indeed. Moreover it also refuses to work reliably with most of my computers and I believe its power consumption that the older computers' USB ports cannot match.
