I am trying to determine which router I should buy. The router will be connected to a wireless controller that is managing about 15 AP’s spread throughout the building. It will be the DHCP server for the guest network configured on the controller. It will also transport the wireless traffic from the controler to an NSA 3600 SonicWall. from the SonicWall traffic goes to the internet. Network traffic is internet based with very little video. The average number of users is about 60 but can go as high as 150. Devices are mixed laptops, Smart phones and Tablets. Any suggestions would be appreciated.
