TL-WPA4220 V1.0: remove TP-Link Beta Watermark after downgrading FW?
I have recently bought a TL-WPA4220-KIT, containing two TL-WPA4220 and one TL-4010 device. I struggle since day one with the WiFi on the TL-WPA4220 devices, the WiFi seems to be very unstable and this was also noticed by other community members.
After it was not any better after I upgraded to the Beta FW TL-WPA4220(EU)_V1_180509_Beta (and I absolutely hated the TP Link Beta watermark what make reading help and settings a nightmare experience), I decided to downgrade again to FW version TL-WPA4220(EU)_V1_170519.
I found both firmware versions on this page https://www.tp-link.com/de/support/download/tl-wpa4220/v1/#Firmware
I was absolute horrified that the downgrade to TL-WPA4220(EU)_V1_170519 does not remove the TP Link Beta watermark, I tried to reset the adapters to factory default, no success.
How can I get rid now of this dreadfully annoying TP-Link Beta Watermark? It is very distracting, annoying and it does not match with the FW TL-WPA4220(EU)_V1_170519 because this FW is not Beta.
I appreciate any help how to restore my TL-WPA4220 back to what it is after downgrading to TL-WPA4220(EU)_V1_170519, it is not beta anymore.
Can you please help how to get rid of this TP-Link Beta watermark?
