signal vs datarate

[muhsi_2015]

Hi,

In what situation  client is downshifting the rate  after a retry happened in higher rate  and even  in lower data rate  its retrying  ?.

Is it  ok  an ipad mini using 24Mbps , Does it can go an higher data rate ? 

Thanks

If the client has selected to go with a lower rate then you would need to speak with the vendor of that client to find out what algorithm they use.

Hi

If there is a power mismatch between the station and the access point then station downshift the rate ?

Thank you

I would say RSSI/SNR or packet retry could lead into downshift rates.

Even AP & Client power mismatch situations resulting retransmissions, so eventually client will try downshift rates.
