Product based on: APQ8016E
WiFI chip: WCN3660B
From the captures made during last months with different APs we see a strange behavior with the “Data rate”.
It seems that after a connection with AP, the communication always starts with lower data rates: 802.11b, 802.11g.
It can be seen in the “802.11 radio information” header of the air captures.
After some time, the data rate increases to 802.11g/802.11n rates.
It is expected that the communication will start from higher data rates and will lower it in case of communication problems.
it’s easily reproduced with Linaro – both 18.01 and 20 – just connect to AP and run openssl command – rate of traffic from device starts with 802.11b.
