Now, let forcefully shut the 6 GHz radio on the AP. 6 GHz channel 5, 80 MHz wide, PL1 – strongest absolute RSSI.This time we disable 5 GHz radio and see if 2.4 GHz or 6 GHz wins.

Using narrower 5 GHz channel makes the iPad connect using 6 GHz instead. We are using the the same configuration as in our very first scenario, but 40 MHz we will reduce 5 GHz channel width to 40 MHz. As you can see, the 6 GHz RSSI is 25 dB stronger than the 5 GHz one, which is why (as far as I can tell). Yes! The iPad Pro prefers 6 GHz every single time. 6 GHz channel 5, 80 MHz wide, PL1 – strongest absolute RSSI (RSSI on the iPad -30 dBm).5 GHz channel 36, 80 MHz wide, PL8 (RSSI on the iPad -55 dBm).2.4 GHz enabled, PL1 (RSSI on the iPad -31 dBm).Let’s use the exact same configuration as above and reduce 5 GHz radio’s transmit power to the lowest, Power Level 8 (PL8). The iPad prefers the 5 GHz band and joins using this band. In this case, the 6 GHz SSID had the strongest absolute signal strength (RSSI) of the 3 bands. M ax transmit power and 80 MHz wide 5 GHz channelĪll 3 bands are enabled with manual Power Level 1 (PL1), which forces the AP to use highest permitted Transmit Power.

Since Apple hasn’t published any documentation that would cover this subject, I configured a tri-band SSID on Catalyst 9136 AP. This time we ask the “Hey Siri, what is iPad Pro’s favourite band?” question. You may have read my 6 GHz discovery test of the new Wi-Fi 6E iPad Pro.
