We have a Meraki wireless system that services the guests in a 50 room hotel. We have 7 repeaters and the router is a Cisco IAD2431-16FXS tied to a T1 connection with 1.5 mb up and 1.5 mb down. Signal stength is excellent thoughtout the building. Until recently the system working perfectly, now if more than about 6 users are on the system crawls. I contacted the internet service provider to check the lines, they said everything is working properly, but we have about 98 percent of our bandwidth being used all of the time? Any ideas.
