"Package Cannot Be Installed (Insufficient Disk Space)"

[gper]

I am a newbie, so bear with me....

Bought a TP-Link TL-WR941ND v3 router (32MB RAM, 4 MB Flash).
Flashed with the appropriate bin file.
Flash successful. No problems observed.

Problem is when I go to the Plugin page and scroll down to the plugin "OpenVPN Support for Gargoyle". It says:
Version: 1.6.2-1
Required Disk Space: 1.736 MBytes
Package Cannot Be Installed (Insufficient Disk Space)

The top of the page (Plugin Options) says:
Plugin Root: /plugin_root
Root drive: 384.000 kBytes Total, 148.000 kBytes Free

The status page (Device Name, Gargoyle Version, etc.) says:
Memory Usage: 12.3 MB / 28.5MB (43.2%)

The whole reason I got this router was to use the VPN functionality. I do not have any other plugins installed (other than English). I do not understand how / where the Root Drive shows 384 kB, when the spec of the router is 32MG RAM / 4MB Flash.

Can someone help me? Thanks in advance.

People uses OpenWrt trunk builds (no web interface) only CLI commands to have space for packages, your router is only 4 M flash, that's all the space left after flash
buy a router with USB, then you will be able to load all packages you need

As danymarc already mentioned above, there isn't enough space in flash on your router. RAM (32 Mb) and flash (4 Mb) are two different things. The most significant difference between these two is, that flash keeps data when power goes off, where RAM doesn't.

You can still get OpenVPN running on your router by installing it into RAM, but you can't do this from GUI.
