I am wanting to control my RPi remotely by laptop PC, but putty doesn't work because it comes up that connection has been denied by my network.
Any other programmes I could use to remotely control the RPi that aren't putty?
Putty is not the problem. The problem is with your network configuration, the set up of your R-pi, or something that you are doing wrong. Either provide detailed information about your set up, what you are doing and what errors you see, or search for ssh problems.
