I have an office in Boston that is located in a 6 floor, 80+ (approx 50-80 users) unit building. The building is much older and is made up of thick walls. The building provides Wifi access and the modem is in the basement with extenders on every floor. I believe they told me the internet package is Comcast business 100Mx10M. Some areas of the building (conference room, parts of my office) do not get internet signal or connect but say limited while other areas (reception area, kitchen) have perfect signal. I have tried using many devices that work at other offices/home and still have the same issue in this building. I do know that it is a built in modem/router they are using downstairs and management said they will upgrade but do not the route to take, apparently they thought the extenders would fix it. Any ideas on how to approach/fix this issue?
