Yes, read the 802.11-2012 standard, some drivers (source code) and play around with them for a while :) > * Changing Fragmentation Threshold and RTS/CTS Threshold may strongly > reduce throughput in some cases, but it is not necessary. >>> My point is: >>> 1.

Most cases should run with the defaults just fine. Typically only extreme cases need any form of tweaking, and categories like the ones you're suggesting do not translate to any sane default configuration changes. - Felix _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
