" Computed values need=20 to be set per hand with sysctl, but it is really simple." Do you think that it is right way ? If S. Long said this: "One of primary reasons for improving wireless support is to give = companies the tools to put FreeBSD into their wireless devices - the guy at = FreeBSD who is adding wireless support is under contract from wireless companies = to do the work," said Long. Wireless device manufacturers may prefer to use FreeBSD rather than the rival open source operating system, Linux, because of features such as = its support for fine-grained access controls and security policies, = according to Long. Source: http://news.zdnet.co.uk/software/linuxunix/0,39020390,39214098,00.htm If I were a wireless device manufacturer and found out that there is no = way how the BFU without knowledge source code for formula about distance = could put these ACKTIMEOUT and CTSTIMEOUT values into wireless devices, I = wouldn=B4t probably choose the FreeBSD as a suitable OS and I would stay supporting Linux in my wireless devices because it has been supporting athctrl for = a long time. In wireless devices as ASUS AirBOX and others which use linux, the user doesn=B4t have to face the task of counting these values on the basis of distance.

Computed values = need=20 to be set per hand with sysctl, but it is really simple.
