øhhh ja.. det står der jo.
Most functionality of WRTbwlog should work on all hardware revisions of the WRT54G(S) routers. I have tested it with the Sveasoft Alchemy 1.0 firmware and got reports, that it's also working with the Sveasoft Talisman firmware and DD-WRT firmware. I guess, it's also running on OpenWRT? (feedback appreciated)
It will not work with the default Linksys firmware, Sveasoft Satori or Hyperwrt, as these firmware versions do not include awk, which is required by WRTbwlog.
