I was wondering if anyone else has run into or noticed an issue with passwords using these switches. I've set up 5 or 6 in the past couple of months and have confirmed it is an issue with both the 2.0.3 firmware and the latest 2.1.16 firmware.
The issue is that you cannot use an & in a password. That is to say, you can use it when setting your new credentials for the switch but once set, you cannot login using this password any longer. I've tested these passwords over and over, making sure I didn't slip off the shift key by removing caps or substituting a 7 instead of the & symbol. I have NOT tried any other special characters but I can confirm that numbers work just fine.
