connecting to open wifi access point?

[Capstan]

I tried the 'flushing cache with 6 different bogus ssid' procedure, and then tried the real one again with no password. Same results.

However I did set up an open AP with a different router and was able to connect to that using a blank password string right away, no problem. So for now I'll assume that in general this must be working. Maybe there is something peculiar about the AP I have been trying to hit, it is in a nearby restaurant. Thanks for investigating, I learned some new things.

I remember that ESP8266 had a problem connecting if a router offered the same ssid both with password and without (apparently some routers have such an option).

After weeks you are telling us, that we help you to hijack a wifi connection

Did the other AP use the same ssid as the old one?

Do try to rename the ssid to the same name.... And see what happens
