Hello All, I'm trying to have a decent wifi connection between two Raspi-3, one is an AP, the other a Client.
Reading lots of threads, it seems that the problem lies in WiFi Power Management. Both machines are: piCorePlayer v6.0.0-b5 | linux 4.19.75-pcpCore_v7 | piCore v10.2pCP | Squeezelite v1.9.6-1198-pCP. However, the Client accepts the command: tc@spark:~$ iwconfig wlan0 wlan0 IEEE 802.11 ESSID:"LaScala" Mode:Managed Frequency:2.442 GHz Access Point: B8:27:EB:B5:22:1F Bit Rate=72.2 Mb/s Tx-Power=31 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on Link Quality=64/70 Signal level=-46 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:65 Invalid misc:0 Missed beacon:0 tc@spark:~$ sudo iwconfig wlan0 power off tc@spark:~$ iwconfig wlan0 wlan0 IEEE 802.11 ESSID:"LaScala" Mode:Managed Frequency:2.442 GHz Access Point: B8:27:EB:B5:22:1F Bit Rate=72.2 Mb/s Tx-Power=31 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=64/70 Signal level=-46 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:66 Invalid misc:0 Missed beacon:0 while the AP returns "invalid argument": tc@Fidelio:~$ iwconfig wlan0 wlan0 IEEE 802.11 Mode:Master Tx-Power=31 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on tc@Fidelio:~$ sudo iwconfig wlan0 power off Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Invalid argument. I am very confused..
