Tool/software: Linux
My machine is connected to BCT router. Im seeing the mismatch in the data rates. iw dev wlan0 link say supported is 65mbps and iw dev wlan0 scan say extended data rate is 54mbps.
a. which data rate is correct?
b. When the data rate is higher than 54mbps, the cable change handling test case is getting failed for the home kit. The duplicate packet (probing packet send by the mac machine is not reaching the LCC) packet loss is happening 4/5 times. Any reason why if the data rate is 72.0mbps, the packet loss is happening? This issue is not happening when the data rate 54.0mbps or less than that. (radio mode : 802.11a/n - 802.11b/g/n (Automatic))
