I have recently noticed that the WiFi in my house has been slow. I managed to isolate the problem to equipment that use the 2.4 GHz (802.11n) bandwidth. Using an RF Explorer, I realized that the 2.4 Ghz is completely saturated (any channel) from devices at our neighbors. As a result, a 50 Gbit speed is reduced to 1 Gbit when the 2.4 GHz channel is used. To be safe, I replaced the WiFi WAP with a new one that supports both 2.4 GHz and 5 GHz. The problem remains, but not on the 5 GHz band. Any equipment on the 2.4 GHz band crawls, any on the 5 GHz band flies.
I have been having problems with connectivity of my SONOS speakers, when I realized that they also use the 2.4GHz band. I have had the speakers for some time now. Both are wireless via a SONOS Bridge, so not my WiFi WAP. Am I to assume that I am doomed, since SONOS uses the same band?
