I have a wireless WRT54G router with the latest firmware installed. If I configure any 1 access restriction, it works fine - but as soon as I try and create 3 policies (which I need for different times on different says I.e Sun, Fi-Sat and Weeknights) then all computer access is denied for that system (I am doing it by I.P. Addess). I have checked and re-checked the settings and everything "SHOULD" be working - but it doesn't.
Not able to think any particular. It might be issue with the firmware. Just check it with www.linksys.com/download whether it is latest one. And go through all the restricting settings one more time carefully.
What is the model number and version number of router, and what is the firmware version on it. And what settings you are exactly doing on access restrictions?
