Agreed I think gigabit ethernet adapters _have_ to be autosensing of MDI
(normal) or MDI-X (crossover) to be considered gigabit capable (ie within
specifications). I expect the crossover adapter may be causing enough
interference to stop 1gbit from working thus resulting in merely 100
mbits.
Furthermore it is entirely possible that it's a 100mbit only crossover
adapter: it might not be crossing all 8 lines since gigabit uses 8
lines and not 4 like 100mbit...
Cheers,
