2. And also I found "Enable OFDMA in 2.4GHz" and "Enable OFDMA in 5GHz" in the debug page. So in default, the OFDMA is disabled? Why? Should I enable it or not to get best performance?
By the way, my main router is Rax120 and 2.4Ghz is running in 40Mhz.
do you live in a congested area (apartment, condo, home with other homes close to it)?
If so, most routers have a 20/40mhz coexistence setting. It prevents the 2.4ghz from broadcasting in 40hz if there's to many signals. This helps everyone's network to run better over 2.4ghz because of its limited bandwidth and overlap of wireless signals.
You can disable this setting but if you live in a congested area, it just makes things worse for your neighbors (and potentially you). Tends to be a a**hole move in those cases.
So even if the router is set to 40hz 2.4ghz channels, if thats enabled, it can just be broadcasting on 20hz.
Thank for your reply. But my rax120 had that 20/40mhz been disabled. The 2.4G signal from Rax120 is 40Mhz, but the 2.4G signal from Eax80 is only 20 Mhz. And there is no any 20/40Mhz options in the Eax80 settings.
