Please could someone help? I currently have a laptop trolley with 16 laptops using a buffalo Airstation WBR2-G54 wireless router. Only 12 of my laptops will connect concurrently. I am looking to purchase a new router as WBR2-G54 is no longer supported by the supplier. I need a router that will support 16 laptops running concurrently, whilst the router is never more than 3 feet away. I look forward to your help.
