Yes, there are still known problems with some APs. Many APs work fine, though. The details of why some APs don't work fine are still unclear. > Trying to connect to the AP in 11n mode does not work.

Does forcing 11g or 11a mode like this fix it? For 2GHz AP: ifconfig iwn0 mode 11g For 5GHz AP: ifconfig iwn0 mode 11a These commands should restore 5.8 behaviour even if the AP is bad in 11n mode. To go back to autoselecting a mode, run: ifconfig iwn0 -mode
