I have changed UMTS provider in between (from Tele2 to 3 in Sweden), and modem (from Huawei E620 to E220). This may explain the differences. However I still have a very similar connection problem, but the patch makes no difference. I tried both pppd 2.4.4 and current git, patched and unpatched. In all cases it tends to fail at the first connection attempt after plugging in the modem. What helps however is setting ipcp-max-failure high enough, like 30. I'm quite sure that the patch was needed with the old provider and hardware, and a few other people have confirmed this. I'll see if I can try another modem. Hopefully someone else can reproduce it?
