I've found similar problems, but not the same, so I've decided to ask about it in a new thread (if I missed a solution please don't be mad at me!) I use WRT54GL v1.1 with Tomato Firmware v1.04.0944 in wireless client mode. I want to restrict access to internet for one of my computers over LAN using its MAC adress. Unfortunately access restriction works only if I choose 'all day' restriction (computer is banned). Choosing any period of day-time seem to be ignored (computer has full internet access). I've synchronised router's time before (by ntp).
