Hi,
I'm noob with OpenWrt, In list available firmware I can see the Archer mr200 but not the Archer mr400. Is it possible to try to install the mr200 firmware ? is it possible to easy customize the mr200 firmware for mr400 ?
Second question I try to use the mr400 for access with voWifi, the router access to internet with simcard. This function is not supported by original firmware (do not reply to ISAKMP and ESP message). OpenWrt can help for this ?
Thanks by advance for hepl, Olivier.
In general, you can't install firmware for one embedded device on another, even if they have the same chip set. Trying to do so may destroy unrecoverable, instance-specific data in the flash (and potentially other problems).
If you have basic C and shell skills and access to a Linux-based development box (or VM), then you could try to port OpenWrt to the device (assuming the hardware is compatible)
Hello. Who can create OpenWRT firmware for this device?
Ready to pay for firmware.
Hi I am using MR6400v5 openwrt firmware on my MR400v2 router. But the wifi chip can only work under 300Mbps rate, with adequate researching I find 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?
OK, finally I successed to drive MR400 AC1200 5G radio wireless chip. It's a PCIE chip, model is MediaTek MT7613BE 802.11ac/n.
I have constructed this project and added the new device into openwrt image builder source code.
Next problem is how to commite the git code changes.... who can tell me?
Hello,
I'd be pleased to try your OpenWRT firmware for ARCHER MR400 v2, but I don't find it on https://downloads.openwrt.org/snapshots/targets/ramips/mt76x8/.
Can you tell where we can download it ?
Regards
Did you see that ?
https://openwrt.org/docs/guide-developer/working-with-github-pr
Nowhere, I wrote some source code and compiled it.
Did you find how to commit the git code changes ?
Yes, I saw that and will study how to do that when I have time.
In the meantime, can you publish your beta firmware on a file-sharing service (like Mega, Free Transfert or GrosFichiers) so that we can test it?
Yes,I can. But what I do is first to flash MR200 firmware then upgrade flash my own firmware. I don't know why it shows so strange 
And I will commit my source code later and notify you.
Do you mean you have to flash the MR400 v2 with MR200 openwrt firmware before flashing your own openwrt firmware ?
Yes, there must be something wrong. And my mr400 now doesn't have 4G mobile data. Only 2.5g and 5g wifi. But to use it only as a wireless extender AP is my requirement. It has only 8MB flash space, so only very few packages I can install in the router.
If you lose mobile 4G data, your firmware really isn't up to scratch.
I don't know if that can help, but did you see this explanation about the MR200's modem ?
OpenWrt Firmware Selector: TP-Link Archer MR200 v1
For MT7613BE add modules: kmod-mt7615e, kmod-mt7663-firmware-ap, kmod-mt7663-firmware-sta.
kmod-mt7663-firmware-sta - for client mode wifi
