OpenWrt in TL-MR3020

Dear Members,

I have installed LEDE Reboot 17.01.5 r3919-38e704be71 / LuCI lede-17.01 branch (git-18.180.55366-b78664c) on my TP-Link TL-MR3020 v1. I need to use this device as WiFi AP to internet connection at RJ45 & 3/4G usb dongle connected to USB port. Please help me as now I do not understand what to do as my device has little space available for any other further packages installation. I have read in a post in openwrt forum is v15 (Chaos Calmer) is best suited for my purpose but unfortunately I could not find the same. Can anyone help me to downgrade / save some space in existing installation so that my purpose is fulfilled.

@sinhx123, welcome to the OpenWrt community!

Be advised that version 15 shouldn't be ran on production devices!

Hope this helps.

Thanks for your reply @lleachii but I can't download the .bin file from the link you have provided. Would you please help me to do the same.

I'm not sure how to assist you with that. Can you see:

Hello @lleachii

Thanks for your support. Actually your uploaded image helped me to understand that I have to click on the particular chipset family link in order to find the correct firmware version. Now it's bit clear to me.

Now can you please explain me if it is possible to import this firmware version using web-interface? ( LuCI lede-17.01) and also 1. what are the packages required to serve my purpose Sharing internet connection through WiFi (RJ45 + USB 4G dongle + Android/iOS mobile usb tethering). Since I have some serious memory limitations for my hardware device I don't want to install any extra package which is not required for my application. :thinking:

I guess you mean "flash" or "install." Just try it, as I don't own a TL-MR3020, I've never reverted to v15 in this manner; and I've never used v15 on a device similar to yours.

I'm not sure. I'm not even sure those packages were available in v15. Hopefully someone else can answer that.

A safer alternative, security wise, is to compile your own version of 17.01.6 with the packages you need built in. This will show you the steps to do it:
