Hey there. Same problem here. Brand new RUT955 with with 06.06.1 FW shipped can NOT establish a data connection using the sim.
Downgrading to 06.05.3 instantly fixes the problem.
Our SIM is part of a private VPN provider (o2 M2M Solution), so we are not even getting an IP with the latest Firmware.
Country: Germany, Network Provider: O2 / Telefonika
Custom APN, using PPP and PAP. CHAP is not working either. QMI / NDIS is not supported AFAIK from our provider.
We also have an older RUT955, which we recently updated to 06.06.01 and the connections works fine.
After the working connection using the 06.05.* FW on our brand new model, I updated again to 06.06.01 and magically the connections works too!After the upgrade back to 6.06.01 the connection works for a couple of minutes, it stops and is not able to start again. So maybe the upgrade path is necessary / the factory firmware is missing something in 06.06.01 what 06.05 had?
