Hi Chris, >> But in previous email, you mentioned the only way is to power cycle the device when firmware crashes. >> We will run some tests and try to recreate this issue, so that our firmware experts can take a look into this. >This is the first chance I had to test both bands at the same time. As per your log, scan command (0x6) got timed out. We don't expect further commands to work after this. If available, please share me the log for the issue in which you faced a problem for 2.4Ghz, but 5Ghz worked fine. -------failure log---------- Oct 28 11:51:04 kernel: [ 1229.175627] usb 1-2: mwifiex_cmd_timeout_func: Timeout cmd id = 0x6, act = 0x3 Oct 28 11:51:04 kernel: [ 1229.175634] usb 1-2: num_data_h2c_failure = 0 Oct 28 11:51:04 kernel: [ 1229.175637] usb 1-2: num_cmd_h2c_failure = 0 Oct 28 11:51:04 kernel: [ 1229.175640] usb 1-2: is_cmd_timedout = 1 Oct 28 11:51:19 kernel: [ 1244.712077] usb 1-2: Ignore scan.
