I lived in an apt building that the only service provider was att, with a required, unique router. Ever person had the same router, and the routers default settings was to blast at full over 2.4ghz with a 40hz spread.
It was completely unusable. Everyone was jamming everyone else.
I bought a router solely so I could turn off 2.4ghz and use only 5ghz.
It was completely unusable. Everyone was jamming everyone else.
The companies deserve all the flak they get in this case. They know it is congested because they are the ones who did it, but don't care to think about it.
The least they could do is to let the user change the settings, but "oooh nooo PICNIC!"
Ideally they should use a WiFi analyser while setting up the device and if there are too many APs of their own company, send a report to their nearby office so that it can be rectified.
