Hello ,
Does anyone know if lan ports still drop connection and reconnect after a while with rc4? Has anyone tested it? I really want to upgrade but i had this issue on rc3 and rc2 which is a dealbreaker for me... I don't know if it is a hardware issue or a specific issue with my router as i don't see many users mentioning it but on @db260179 19.07 build it isn't happening and i even had a 60 day uptime at some point without any connection drop.
Thanks
OpenWrt 21.02.0 RC4 image is ready for mir4a: https://downloads.openwrt.org/releases/21.02.0-rc4/targets/ramips/mt7621/

Hi,
I think you can test it yourself without flashing to your router with initramfs image.

Hello,
Which firmware are you using? You must use the Chinese stock firmware for recovery process.

When you mention of "drop connection and reconnect" what are you referring to this issue?
[17965.105187] mt7530 mdio-bus:1f wan: Link is Down
[17968.177242] mt7530 mdio-bus:1f wan: Link is Up - 100Mbps/Full - flow control off
I am having a similar issue on another hardware model, I described it in the following post:

Hello,
Yes i was referring to this issue , i had it on all the builds i tried(even on 19.07) except for @db260179 builds so i guess he knows more about this switch issue.
RC4 is officially annonced.
Most likely the eee mode (energy saving mode) is triggering a port shutdown. The mt7621 has a few hardware bugs, if someone just looks at my v19.07 patches and mimics the similar feature turn offs, should help the issue.
Thank you for this information @db260179, can you point out to which patches exactly?
I am willing to dig deeper into this and find out if it's a software issue or not.
Hi,
I ordered a refurbished Router 4A Gigabit Edition at Amazon and did not notice, that they delivered the wrong model (4A 100M, not Gigabit).
So I flashed the wrong firmware with OpenWRTInvasion and bricked it.
I can unbrick it via TFTP with 2.18.28 or 2.18.58, but those are both chinese.
Flashing OpenWrt via OpenWRTInvasion (now the version for non Gigabit Edition) is working as well.
But i would like to send it back and get a real Gigabit Edition.
I there any chance to get it back to the international Xiaomi firmware?
Flashing the 3.0.5_INT does not work, get's bricked again. Anyway I think that one is for 4A Gigabit, not for 4A 100M
Thanks for your help.
Yes, i got the information for debricking from hoody's guide. But that way I only get back to chinese UI. And sending it back to Amazon with chinese UI or with OpenWRT is probably not okay.
So I am looking for a way to get it back to the english UI, but the only international firmware (3.0.5_INT) i found does not work on the 4A 100M.
I tried using 15 meters lan cable for good but in RC4 it's kinda weird after rebooting my router my internet connection is losing even though my 2nd LED is blinking,in my other snapshot build this isn't happening....is that a bug or something? or is it because of the VLAN configuration thing?
Hello all,
Does anyone have the schematic of this router? Where should the legs of the spi flash be connected?
I accidentally damaged some spi pads on pcb while desolering the spi flash. I want to fix damaged traces/pads with enamel jumper wire. But I'm having trouble tracking the copper traces on the matte black colored PCB. My eyes aren't doing their job as well as I'd like
Thanks in advance.

Hi all.
Currently, I use a vm on my server which hosts a wireguard server so I can acces it from anywhere. Sometimes, the VM would hang itself up.
That's why I consider having wireguard on my openwrt xiaomi 4a. Is it something to consider
The openwrt router acts as a Dumb AP in the home network.
Seems someone has up streamed a patched to turn these features on or off.
A patch for 21.02?
This is some very useful info! Unfortunately I cant find any documentation on how i am supposed to turn this feature on/off.
Edit: Seems like you disable it by
ethtool --set-eee eth0 eee off
If i understood correctly. (Someone please correct me if i am wrong)
