I use 4 different little mobile computers and was getting denied on one of them. The error message said, “You have an error. This user already logged in from another computer, only ‘5’ logins per user allowed.
I have been to over 50 different libraries and used the wifi. This is one of the most peculiar firewall settings I have seen yet. They are very hard on general guest log-ins here. Most libraries don’t seem to bother with controlling access with passwords. I don’t understand why these people here decided on creating a password in the first place.
