One of the solutions that seems to work is that found by David here: > [@AR750: Firmware 3.201beta2 - no free space at all to do anything](https://forum.gl-inet.com/t/ar750-firmware-3-201beta2-no-free-space-at-all-to-do-anything/14602/5): > > Thank you all very much for these explanations. I am not a technician at OpenWRT, so I learn slowly. I finally got the AR750 to work fine. I discovered the new Mountpoints feature in Luci. To solve my problem, I factory reset my AR750 so I have about 150 kb free. I had an old 512MB USB stick, I formatted ext4, and I use the new Luci feature in firmware 3.201 Mountpoints to do the overlay mount point … reboot … now I have 477mb extra and then I restore my settings so I can make changes and inst… and here: > [@2MB free on AR150 after installing 3.201](https://forum.gl-inet.com/t/2mb-free-on-ar150-after-installing-3-201/15859/7): > > Hello! You have an USB slot. You can put an old USB flash memory there (a little and tiny model not big) and make extroot /overlay to add this USB memory extra space to the router. For example USB is 512Mb, you will have 480Mb extra space for adding plugins, etc… This is very easy in firmware 3.201 in Luci \> System \> Mount Points \> Add \>Select USB Device\> /make Overlay \>reboot. I have did this with AR750, same space problem after update to 3.201 firmware. Bye --- _[View the full topic](https://forum.gl-inet.com/t/ar-750-creta-free-space-issue/16085)._
