I didn’t choose to save settings because I read that used more space. But now when I click More Settings \> Advanced, it shows Luci not installed yet with only 18% (2MB) free space remaining. I just want to ask if this is normal, this is on a new router. If this is normal, how can I free up some space? I’d like to install Luci, and I also need to install another package. ---

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.

Let me be clear: 3.201 contains important bug fix, major openwrt upgrade to 19.07. Read the release notes before you upgrade. OpenWrt 1907 needs more space for the kernel and this cut the available space. If 2MB is not enough, you can use clean openwrt firmware, use exroot, or use old firmware. It is just easy. If you prefer to use a vanilla openwrt firmware well, why keep criticizing the default firmware. ---

FWIW, I did see the low space warning before installing Luci which helped inform me about the issue. ---

> [@alzhao](#): > > I_ **f you prefer to use a vanilla openwrt firmware well, why keep criticizing the default firmware** _ Using the OpenWrt firmware was NOT my preferred solution, but it was forced on me as the default firmware does not function how I need it to in all my use cases. The other issue I have is about half my GL iNet routers are still not supported by a released version of OpenWrt firmware, so I am forced to use the GL iNet firmware if I wish to use the routers at all. Hopefully once OpenWrt 21.02 is released, I will have a choice of firmware for all my GL iNet routers. I believe that all users of GL iNet routers hope for better firmware from GL iNet in the future, so we don’t have to look for other firmware solutions. We take the time to make these comments so maybe someone will take note of the issues and fix these issues in future versions of the firmware. Since you took away the bug list, the forum is the only place we can bring up issues with your firmware. _ **“Although your customers won’t love you if you give bad service, your competitors will.”** _ _Kate Zabriskie, Founder Business Training Works_ ---

/etc/tertf/mac\_vendor.db Then uninstall gl-tertf. The only reason for doing this is to create room if you need it to install something else, I think, and most of these packages are really small. I think all you need is one free byte at the end of the day. Any free memory is just going unused. I’m wondering though, if I built an image without these things, would I I create twice the free space? Edit: I poked some more at this with my Mango and built several images with Imagebuilder (new to me, but the instructions are very clear). I got rid of all the ipv6 stuff, also ppp, gl-tertf and a few other things. Never could get rid of nodogsplash. That image was 1 meg smaller, and I ended up with 3.7meg free. Then I added back in luci, nano, htop, adblock, sqm and the associated luci files, and ended up with an image about .5 meg larger than stock but with 2.7meg free. This was all really fun and easy. I just have to remember if I run into issues to flash back to stock. But it does seem straightforwrd if you have size problems to delete some stuff and make room for other stuff. ---

Try several times, I don’t know why but I had to do several times and reboot each time. I saw that some people had ticked option Enable but I don’t have it enabled and it’s ok. May be i had enabled before I rebooted and then it was not enabled again but when I saw the extra space was ok then I didn’t touch it anymore. Good luck. ---
