My Mac is connected wirelessly to my broadband via a Belkin router. No problem. What I would like to do is restrict access from other wireless users of my broadband connection, eg. laptops at certain times of the day on particular days of the week. I thought I had the method from the router's help pages (below):- Client IP filters The Router can be configured to restrict access to the Internet, e-mail or other network services at specific days and times. Restriction can be set for a single computer, a range of computers, or multiple computers. To restrict Internet access to a single computer for example, enter the IP address of the computer you wish to restrict access to in the IP fields. Next enter 80 and 80 in the Port fields. Select TCP. Select Block. You can also select Always to block access all of the time. Select the day to start on top, the time to start on top, the day to end on the bottom and the time to stop on the bottom. Click "Apply Changes". The computer at the IP address you specified will now be blocked from Internet access at the times you specified. Note: be sure you have selected the correct time zone under Utilities> System Settings> Time Zone. I tried this but at the times specified on the days entered laptops can still access my broadband connection. Why...and what do I need to do to fix this please?
