Are You sure that You need rb1100ahx2? What is the speed of Your Internet connection?but i want user manager for paid hotspot.
You can also use RB850Gx2, it have L5 license level (500 hot-spot users), user manager module, and it will be enough for Your Internet connection.my speed is 30mbps/30mbps up/down. i said about rb1100ahx2 because it is the first L6 model.
buying just a L6 licence is 250$ . so why not to buy rb1100ah2 for 300$.
