Cannot connect to WiFi - Incorrect password

memph

Hello,

I have recently changed my access point and am no longer able to get the Duet 2 to connect to the network.

WiFi reported error: Wrong password while trying to connect to Fake SSID

I have performed;

M552 S0
M588 S"*"
M587 S"F'A'K'E SSID" P"M'E'M'P'H'''S'F'A'K'E'P'A'S'S'W'O'R'D"
M552 S1

I am currently on FW 2.05.1.
I am using YAT to communicate on the COM port.
I have managed to get the board on the network with a similar SSID & password combination before.
I have disabled 5GHz on the AP, although this makes no change.
My password has lowercase and a aphostrophe in it. I have escaped these characters in M587
- Later on I removed the aphostrophe from the password - no change
I can confirm the Duet can connect to an open network.
I have put a dummy SSID in slot one as it was mentioned that the flash on the WiFi wears if written to too many times. I don't beleve this is an issue for me as M587 has never been in my config.g but worth mentioning. - no change
I have applied M587 through a macro to get around password input - no change

I would post my M122 here but it gets flagged as spam.

Any advice will be very much appreciated, I'm a bit at a loss what to do here on out.

@memph when using YAT you don't need to use the ` in front of letters you want to be lowercase. Just type them normally.

Clear the saved passwords with M588 S"*" before sending another password

@jay_s_uk Yeah, I've tried every combination.

P"M'E'M'P'H'''S'F'A'K'E'P'A'S'S'W'O'R'D"
P"Memph''sfakepassword"
P"Memph'sfakepassword"

Doesn't change anything, which is why I tried using macros to try to avoid the problem altogether.

The ESP32 wifi modules are used in wifi controlled light bulbs and power switches, as well as the Duet boards. I have found through experimentation that they have some real limitations on the SSID and passwords they can use. Pick a simple 6 or 8 character password using letters and digits only. No spaces, no commas, no quotes, no apostrophes, no symbols. The same goes for the network SSID. Keep it simple.

@mrehorstdmd I appreciate your help and I'm sorry for what will be a very anticlimatic conclusion.

The board wasn't lying when it reported a bad password, because it was a bad password - I had misremembered a single character in it. One of those days I guess.

But for anyone in the future who may find this post I can confirm that;

Capitals, lowercase and spaces in the SSID work, apostrophes will also probably work if you escape them
Same goes for the passwords, and it can take 25 character length

I'm sorry for wasting everyones time.
