Once crystal is stabilized, RESET is de-assert and it becomes an input. Also at power up, WizFi210 don't require a reset, as it have a power-on-reset already built in. So MCU need not assert unless there is a real issue (E.g. hang). -

There is no problem. After power on, WizFi210 would try to connect to a specific AP. That is the default setting. In short, WizFi210 boots within 100ms and tries to connect to a specific AP for 3~5 seconds. - Page 42 LEDs of WizFi210-EVB. Q) What is the difference between WizFi210 and WizFi220? WizFi220 uses an external PA for higher RF output power. WizFi210 has the merit of low power consumption and WizFi220 has the merit of long-range feature.
- Page 43 Q) What is the max-throughput of Serial-to-WiFi? The default baud rate of WizFi210 is 115200bps, but you can change it to 921600bps with AT Command. However, you should consider using the hardware flow control in such high-baud-rate. If you set the baud rate to 921600bps and measure the throughput of Serial-to-WiFi and...
