But I wasted/sacrificed a few days (weekend= s!!!) and found no solution to my problem online, and almost got to a point of hopelessness and giving up on freebsd. The problem: - ping 127.0.0.1 or assigned ip - 0% packet loss; - ping [some remote host] > 20% packet loss (both ways); 1. The issue exists for 11g regardless of WPA2 or authmode:OPEN (no wpa_supplicant); 2. It=E2=80=99s not due to faulty hardware; I have two ThinkPad T43 (I know= , it=E2=80=99s 2017, but I=E2=80=99m a sucker for this kind of fun), they both exhibit the= problem; 3. There are absolutely no issues with setting up wlan0 interface: cloning (ifconfig wlan0 .. create wlandev iwi0..), wpa_subblicant, dhclient wlan0 = =E2=80=93 everything works like a charm. Thank you!!!; I didn=E2=80=99t want to give up on freebsd w/o a fight and started trying = out different =E2=80=98ifconfig .. create ..=E2=80=99 settings. The ' -wme' field did the trick for me: # ifconfig wlan0 create wlandev iwi0 -wme up I only have 1% packet loss now, which I can live with. # pciconf -lv .. iwi0@pci0:4:2:0: class=3D0x.. .. device =3D 'PRO/Wireless 2200BG [Calexico2] Network Connection' class =3D 'network' .. # ifconfig wlan0 list caps drivercaps=3D.. Hope this helps someone. -epmakk
