Hi All,
Odd problem, trying update to latest firmware, but everyone I try, I have an error message of :
Image uploading failed. The selected file contains an illegal image.
I have tried:
A factory reset
Using only "official" updates
Any advice on this?
Model : bipac 8900ax r2 1600
Download via Vivaldi Browser on an apple Mac.
Never had a problem before,
No unusual firewall / malware filters enabled.
Thanks in advance
Ed

Hello!
My router model is BiPAC 8900AX2400
Firmware - 2.52.d23
When I tried to upgrade my firmware with the file Zcomax8900AX2400_2.52.d46.afw, I receive the answer: Image uploading failed. The selected file contains an illegal image.
How can I decide this issue?
