I've got a speedtouch 585v6 and i want to block a computer connecting to the internet, can this be done, i want it so i can block and unblock it as i please?.
That isn't the problem. The OP wanted to block internet access and I was pointing out that he would also block network access which may not have been what he wanted. I investigated blocking internet access only some time ago and I couldn't find any way of doing it.
Blocking network access aswell is just fine, as i can just put the computer back on the network when i want the computer to use the internet again, i'll have a look into this when i get back home and report if i successfully managed to do it.
Looks like i've figured out how to do this now, you just click on the device you wanna take off the internet, and then click configure, and there is a box sayin allowed on wlan and you just untick and tick for internet access.
