Hi, We are working with the Weibu F3C MiniPC which includes BCM43455 SDIO wifi chip 0x004345(17221) rev 0x000006 Testing Linux 4.15, this wifi adapter is unable to authenticate with the MF928 MiFi Access Point which is common in Africa. The STA sends the authentication request, which is ACKed by the AP, but then the conversation ends there (a timeout later bubbles up to userspace). Windows 10 with broadcom driver version 1.605.1.0 is also unable to connect. My laptop with ath10k can authenticate and connect fine. There the conversation is: 1. STA sends authentication request 2. AP sends ACK 3. After 0.1s timeout, STA sends another auth request 4. AP sends ACK 5. AP sends authentication response 6. etc. Also confirmed the same pattern on a couple of smartphones, where the delay seems to be 0.3s before repeating the authentication request. Clearly this AP is not behaving correctly; the authentication request should not have to be repeated. However of all the devices to hand, unfortunately only this broadcom device is unable to connect. Is there a way to adjust the driver/firmware to repeat the authentication requests when they are not responded to? This would match the behaviour of other devices and work around this issue. Thanks Daniel
