Cant Creating Symbolic Link in /www ... please help

[WLAN-Fan]

Hello,

i want to create a Symbolic Link in the /www Directory of my WL-HDD with Oleg FirmWare. But i cant this do.

The Mesage is:

Befehl 'ln -s "/tmp/harddisk/wwwzusatz" "wwwzusatz"'
fehlgeschlagen mit Beendigungscode 1 und Fehlernachricht
creating symbolic link `wwwzusatz': Read-only file system.

I thin the Problem is, that the /www Directory is stored in the read-only RAM.
Is it the RAM?

Where can me help to compile or an other Way to get a Symbolic Link in the /www Directory of my WL-HDD?
The Destination of the Symbolic Link in the /www Directory is the Directory /tmp/harddisk/wwwzusatz.

Many Thanks for help.

WLAN-Fan.
