Sounds as if you have different microcode in these two modems. I tested modems for many years and know that the microcode makes a lot of difference. I have a V.34 which will connect at 33.6 every time. Only problem is that it runs a lot of errors (retransmits) and performs better at 28.8. Thus the throughput is better at 28.8 than at 33.6.
