OpenWrt for Xiaomi Mi Router 4C

can you look into this: won't work on 3.0.23 / 2.14.87; HTTP body attached · Issue #69 · acecilia/OpenWRTInvasion (github.com)
I'm having the same issue.

Try running exploit again or install this image via tftp.

I tried that, and I'm getting no TFTP requests back from the router:

Edit: issue resolved, it was Windows black magic. Check out the github link if you're facing the same issue. won't work on 3.0.23 / 2.14.87; HTTP body attached · Issue #69 · acecilia/OpenWRTInvasion (github.com)

it does, I just tested it - check out this link for full guide: won't work on 3.0.23 / 2.14.87; HTTP body attached · Issue #69 · acecilia/OpenWRTInvasion (github.com)

i wanna understand something , in the router page , it says the wifi is not stable with these device ! does the wifi work or not ?! does it become only lan ? if the wifi work is it bad (weak signal ) , how does it compare to the xiaomi mi 4a gigabit edition as of range and stable wifi connection ? can anyone speak from experience , i wanna buy it and it will be only used throug wifi only, help ...

Wifi works just fine most of the time but rarely it dies. I suggest you to go for mi router 4a gigabit edition because it has 5ghz support.

thanks you for your help, i will be buying the mi 4a GE then.

Very Appreciate.

If you could Add IKEv2 VPN Support to Next Firmware It would be best Firmware ever.
Also Add Support 2048 bit Key for Openvpn UDP because It's not working.

Thank you very much.

There is nothing I can do. Builds are official now and I'm no longer involved in compilation process.

On 4C router. From some reason I can't access the web portal from my PC, but it works from my phone.
From my computer I get "Connection Refused".

Tried resetting the device a few times.

Any solution?

You can try our build, includes support for OpenVPN, IKEv2 and WireGuard: https://www.pcwrt.com/downloads/

Is the wifi stable??

Yes, wifi is stable.

Add more VPN protocols such as PPTP, L2TP, V2RAY , SHADOWSOCKS

How can I install luci on your package? I want luci.

This build has no wifi interface/enabled. I can't find a way to enable or install wireless

You can install the admin-full module as usual. But some functions are not compatible with LuCI, e.g., wireless, VLAN, VPN etc.

Add new wifi interface.

opkg update && opkg install luci
