Users report that one of the access points seems not to be working properly. When they go to download files, it takes forever, but when they move around a large structural pillar, connectivity improves. The sysadmin noticed that the access point is pretty old and should be replaced with a more powerful one. What issue would replacing the access point help to fix?

A$.$RF attenuation

B$.$Interference

C$.$Speed

D$.$Distance
