I resolved it by changing wifi router.

just by chance, the wifi is NOT an 5Ghz wifi but a normal 2.4Ghz ? afaik most of the 8266 can only work with 2.4Ghz

comapring a mac to an esp in this case is comparing a top tier mercedes with a smart

PS: the timing ... haha ... but for completeness sake, it also can only deal with b g and n by datasheet (but despite supporting n, not 5Ghz, based on boards implementation i guess?)

It can't show both of 5Ghz and 2.4Ghz. I guess the problem was the router itself.

All esp are 2.4ghz only. Almost all wifi socs are with a few expections
