Q. There is no WIFI in the corner area (near the AQ) of the 6th floor.
A. I have tested the 6th floor and, while there is a signal, it is poor in that area. Unfortunately, wood and concrete absorb WIFI frequencies and there is no shortage of both here. Furthermore, every seat on the 6th floor is taken and most of those people have 1 or more devices which are all competing for a connection to the access points. I'm afraid this issue is an infrastructural one.
