I had some troubles once with db9 and RJ45... It was due to an impedance pb. As I remember, you have to change the impedance in the adaptor (with adding some R-C)... I haven't done it, and my line was half-working (sometimes yes, sometimes not...). So, I suggest you to check if the impedance are the same...
