Opening EDIT wireless network settings and saving always results in wifi passcode being corrupted or removed

Seen similar with other vendor (not sophos until now).

do you use some special characters within wifi passcode?

Possible the passcode string is split/corrupted while loading and saved incorrectly.

try a simple / short passcode.

Yes, it's a VERY long alphanumeric password with many special characters to keep it secure. A simple password is not safe to use since even WPA2 can be cracked. I have used a shorter passcode before and have noticed that an unauthorized device had been authenticating with my network, so I changed it and since then I use complex passwords.

Longer than 15 characters, Alan?

Its over 20.

I think the current estimate of the difficulty of breaking a password like r(tqrB2CWs:x!+cQ (16 characters) is that it would take ten million of the fastest computers working together 10 years to crack.  Then again, maybe this is a WiFi network in a nuclear missile silo...

Seriously, I'm curious, at what size does the corruption occur?  I would guess that the program that encrypts to store and then decrypts to use may have its limitations.

Until Sophos implements WPA3 on their access points, I'll continue to use sophisticated passwords. And if you think a 20 character passphrase is overkill, you should see how long my SSL VPN password is. :)
