OpenSUSE Wireless :: Mobile Broadband HUAWEI E1756C Connect But Do Not Surf ?

I am trying to use the HUAWEI E1756C USB stick to connect to the internet. Installing usb_modeswitch and usb_modeswitch-data allowed networkmanager to "recognize" the stick and set up a mobile broadband connection.

The result is that NM succeeded in connecting (one of every five attempts) but firefox does not surf, nor emails can be downloaded etc. Just like if not being connected. The USB modem shows the steady blue LED as connected.

A NM issue? I have tried disabling NM control and tried with PPP clients like NMTSMON, wvdial and even Sakis3g. All with the same results. They seem to connect and show flux up and downloaded but no surfing.

resolf.conf shows is pretty much empty and no DNS there.

The working settings in Window$ are:

Same settings with Sakis3G, or NMTSMON or NM result in connection with no action from applications that use the internet.

I have had a similar issue with WLAN each time I change to a different network. I solve that by forcing to update the DHCP. I mean using -su dhcpd wlan0

But attempts like dhcpcd ttyUSB0 or dhcpcd ttyS0 get the same result. So no idea if this is an DHCP, or DNS or another issue.

My box is an ASUS EEEPC 2005H netbook with OpenSuSE 11.2 and KDE
