I've recently updated the firmware to 188.8.131.52-026. My donwload speeds have dropped dramatically with P2P or itunes and ipad, iphone and air can no longer find airprinter, the pc finds and prints to it OK. Does the new firmware support bonjour? Any advice on changing settings etc would be greatly appreciated as although I'm fairly tech knowledgable I have little experience with routers. I'm at the poit of restoring it to factory settings and starting again unless someone has advice.
