same with me.
I was not able to connect at all in N-only mode, in N/G mixed mode i can connect but unusably slow. What shocks me is that if this is an issue with iwlagn or network manager shouldn't this be effecting more people?
what could have changed in the parts specific to the Centrino Ultimate N from 11.04 to 11.10?
do any of you guys have any work-a-rounds that make the system usable? have you tried a fresh install?
