Hi,All: Have you ever met such problem? ---- On hostap mode: I use iperf3 to set up a client and server for testing the performance of wifi. But, wlan0 often down and I can't ping successfully to server on client side. The logs: wifi_log# grep phy0 * 0.0.log:[ 26.269709] Registered led device: phy0-led 0.0.log:[ 26.295254] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' 0.0.syslog.txt:Oct 16 17:35:04 WR-IntelligentDevice kernel: [ 26.269709] Registered led device: phy0-led 0.0.syslog.txt:Oct 16 17:35:04 WR-IntelligentDevice kernel: [ 26.295254] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' 1:Oct 16 13:39:29 WR-IntelligentDevice kernel: [ 74.209275] Registered led device: phy0-led 1:Oct 16 13:39:29 WR-IntelligentDevice kernel: [ 74.233835] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' 2:[ 74.209275] Registered led device: phy0-led 2:[ 74.233835] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' log1:[ 187.283480] Registered led device: phy0-led log1:[ 187.340005] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' log1:[ 937.014207] cfg80211: Found new beacon on frequency: 5745 MHz (Ch 149) on phy0 root@pek-bliu2-d3:~/Desktop/wifi_log# root@pek-bliu2-d3:~/Desktop/wifi_log# grep fail * 0.0.log:[ 1.127111] acpi PNP0A08:00: ACPI _OSC support notification failed, disabling PCIe ASPM 0.0.log:[ 2.298207] button: probe of LNXPWRBN:00 failed with error -22 0.0.log:[ 2.754792] lpc_sch: probe of 0000:00:1f.0 failed with error -16 0.0.log:[ 4.288308] i2c_eg20t: probe of 0000:05:0c.2 failed with error -16 0.0.log:[ 360.510445] cdc_acm 1-2:1.1: acm_ctrl_irq -
