When the hardware is supported, Wireless support under *BSD is fairly good IMHO.
The above is correct for Broadcom Wireless with emphasize on Fairly
.Broadcom support including using Ndisgen has it's shortcomings. The signal will be dropped about every 40-90 minutes. Of course that is not the case for FreeBSD supported cards of which Broadcom WIreless is not.
I have posted a few threads here and there in these forums and have had success with ndisgen. Rather then repeat it just use the Search link here and type in ndisgen.
I will be upgrading to PCBSD7 rather then a new install this weekend to try the Beta. If that doesn't work then a complete install will be in order and I will post back. I will use a Dell Inspiron 5100 w/ Intel pentium 4, 2.5 ghz, 1gb mem, 64mb ati video. The laptop has a Dell 1350 TrueMobile Wireless which is Broadcom and uses the bcmwl5 Windows driver. So, in a day or so we will see if there is Any
improvement. I am not expecting a revelation. However I am hoping that PCBSD7 (FreeBSD7) will have improved networking and better interpretation of the ndisgen produced driver for the Wifi.
One last note. I have downloaded the PCBSD7 DVD which is supposed to be complete and not needing a second CD. So, the extra apps (PBIs) should be on the DVD.
