Confirmed...after upgrading from 7.10 to 8.04 it defaults to about half the signal level and sets the bit rate 1M.
Running 'sudo iwconfig wlan0 rate 54M' increases the tranfer rate but the signal level is still a lot lower then in 7.10. $ iwconfig wlan0 wlan0 IEEE 802.11g ESSID:"freebsdap" Mode:Managed Frequency:2.447 GHz Access Point: 00:14:6C:72:86:52 Bit Rate=54 Mb/s Tx-Power=27 dBm Retry min limit:7 RTS thr:off Fragment thr=2346 B Link Quality=45/100 Signal level=-60 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 $ sudo lspci -vvv 03:00.0 Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01) Subsystem: ASUSTeK Computer Inc.
