Model  is BE450/BE7200, without this option I have to go with BE7000 PRO
Unable to write to usb hard disk, read only.
smb: prompt can't copy, need XX GB (size of copied file) or more space
ftp: can only write files under 15mb.

windows11 and android are both unable to write.
Windows has enabled all the functions of smb1.0.
Tried admin with password, not working

No problem connecting directly to the hard disk.
tplink archer c2300 No problem.

C2300 sometimes need to unplug the HDD again because some software messes up the HDD and makes it inaccessible.
BE450/BE7200 is not this problem, it can't write from the beginning.
