@Chris-Cross 2 things... do you have WAN Settings Overrides disabled before adopting the 8411? BY chance, if the fritz box and the 8411 on the same subnet?

@joems I think I read your post wrong... but You can access the controller from another PC... You will need to enter https://IP OF THE CURRENT PC:8043 in Chrome and you can log in. May have to edit...

@joems You can back up your current settings. Install the controller on a another PC and import them. You have to remember to assign the NEW PC the current PC's IP address. It will all link back.

I have had this firmware running at 4 major sites... with no issues. With IPS enabled. Since 09/05! Great Job Tplink!!

@Hertog_Jan If it gets ignored... that usually means the file path is wrong or the file name is wrong. I have PXE boot working with windows sccm and MDT.

@Glupikocz consider trying this: https://community.tp-link.com/en/business/forum/topic/615998 Read the changelogs EDIT: nvm you have the V1... Junk it and buy a V2.
