We can re-enable it later if / when firmware rate adaptation will be ready; however, this step will be required anyway - for firmware-less builds. - Force RTS / CTS protection frame rate to CCK1 (this rate works fine without any additional setup; no better workaround is known yet). The problem was not observed on the channel 1 or with CCK1 rate enforced ('ifconfig wlan0 ucastrate 1' for 11 b/g; not possible for 11n networks due to ifconfig(8) bug). * I'm not sure if it works before r290439 because - AFAIR - I never seen firmware rate adaptation working for 10-STABLE urtwn(4) (It needs EN_BCN bit set and RSSI updates at least). Tested with RTL8188CUS in STA mode (in regular mode and with disabled MRR - DARFRC*8 is set to 0) PR: 233949 MFC after: 2 weeks Changes: head/sys/dev/rtwn/rtl8192c/r92c_reg.h head/sys/dev/rtwn/rtl8192c/r92c_tx.c head/sys/dev/rtwn/rtl8192c/usb/r92cu_init.c --=20 You are receiving this mail because: You are the assignee for the bug.=
