I have a PC desktop, macbook and a work laptop (PC). The latter two connect via wifi. I would like to add security to control who can connect to my router. I can either set MAC filters or encrypt the network. However, I VPN into my network at work on the laptop and the VPN won't work with encryption on. In the past I've just used MAC fiters, but I now hae a macbook. When I apply my MAC filters (including the macbook's MAC address) the macbook does not connect anymore. Does anyone know how this could be fixed, or if there is another solution I could consider?
