Hello @capsia37, sorry for the long delay. Have you found a solution? Did you try an older release?

Yes, I've tried the previous versions, but I couldn't install the package because the kernel version is 5.4.124 instead of the required 5.4.134. I don't know why the package wants exactly that version, maybe it can be recompiled to work with 5.4.124.

A new version has been released, try it out. It should have a kernel version >= 5.4.134.

Thank you! Now it doesn't show errors, but there is not enough space to install the package

It seems strange to me as it is marked as a 8/64 device, but only 5.6MB are shown in the partitions above using df -h. When I installed it with the official 21.02 image it showed 2.4MB free in Luci. How can I check if there is unused space?

The best option is to build the image with all the packages you want instead of installing them to save some space. If I am not mistaken, the result of the df command you showed seems to be correct.

Thanks for all the help! I'll try to build an image with the packages.

What might be the password for ssh on factory firmware?

I tried this on TP-Link TL-MR6400 V5 but had no success, because of insufficient drive space to install the package "modemmanager".

So here are my steps using QMI and the simple LuCI configuration interface.

Hi, can you help me to add 2 packages iptables-mod-ipopt & kmod-ipt-ipopt to openwrt firmware? Your firmware builds very well but I can't install the above 2 packages, it's not compatible
Thank you very much!

Hi I am using this MR6400 openwrt firmware on my MR400 router. But the wifi chip can only work under 300Mbps rate, the only difference between MR6400 and MR400 is that MR400 has a AC1200 Mbps wifi chip. So how can I patch a driver module or build a firmware that supports AC1200 wifi chip? Or someone know how to do that then help me?
