Xiaomi WiFi Router 3G

For Developers
552

Hi all,

i'am currently testing latest version from Feb 9th (https://downloads.lede-project.org/snapshots/targets/ramips/mt7621/)

I have 3 different 2.4G and 2 different 5G Networks defined.
There are also 3 Interfaces defined, behind one of this Interfaces are all my IoT stuff (~20 Devices).
One Interface is for my DSL Connect and one for the rest (~10 devices).

Overall WiFi Perfomance is not really good and stable, some of the IoT devices based on ESP8266 chips are having trouble while connecting.

IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)

iPhone Disconnect more often:
IEEE 802.11: disassociated
IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)

I have set option disassoc_low_ack '0' in /etc/config/wireless but no luck.

Are there any Images for testing or is there somthing i can do to make this System more Stable.

Regards

LuFi

Problems with 2.4 GHz solved with latest commit, thanks @nbd

554

I'm using 2.4 Ghz and 5 Ghz without any problems on Kernel 4.9.

this ?

556

@Cryptage Thanks, so the cause of random reboots is other.
@lfiebach Yes

557

thx, i will test Tomorrow, i don't think that this patch is included in todays build.

558

ok, short question to the specialists here.
Currently i'am switching between Prometheus and OpenWrt.
This is caused by some problems in OpenWrt and Performance testing.

Prometheus uses a different layout.

dev:    size   erasesize  name
mtd0: 00080000 00020000 "Bootloader"
mtd1: 00080000 00020000 "BootEnv"
mtd2: 00500000 00020000 "Factory"
mtd3: 00140000 00020000 "Kernel"
mtd4: 012c0000 00020000 "RootFS"
mtd5: 00100000 00020000 "Config"
mtd6: 00400000 00020000 "Storage"
mtd7: 06080000 00020000 "RWFS"
mtd8: 01400000 00020000 "Firmware_Stub"

And to switch between this Systems i always install Stock OS, enable SSH and install OpenWrt / Prometheus.

Is it possible to directly switch between this two Systems ?
Is it possible to install OpenWrt and overwrite Prometheus ?

Currently i compile a fresh OpenWrt Version for testing .....

thx

If you want do tests there are also these driver but you must use 4.4.112 kernel (info)

560

i was only switching from LEDE (4.9.77) to Padavan project (using prometheus) cause i have had problems with PPTP VPN that one of the companies using... on Padavan was working as expected:) but i do not like to loose so worked on LEDE with 4.4.0.112 kernel and working like a charm:) but was switching like you from Padavan to stock and then to LEDE, found this guide but didn`t checked it...

  1. on lnx system:
    cp lede-ramips-mt7621-mir3g-initramfs-kernel.bin firmware.bin && truncate --size 4194304 firmware.bin && cat lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin >> firmware.bin

  2. then in padavan thru SSH:
    /home/root # cat /proc/mtd
    dev: size erasesize name
    mtd0: 00080000 00020000 "Bootloader"
    mtd1: 00080000 00020000 "BootEnv"
    mtd2: 00500000 00020000 "Factory"
    mtd3: 00160000 00020000 "Kernel"
    mtd4: 012a0000 00020000 "RootFS"
    mtd5: 00100000 00020000 "Config"
    mtd6: 00400000 00020000 "Storage"
    mtd7: 06080000 00020000 "RWFS"
    mtd8: 01400000 00020000 "Firmware_Stub"

send firmware.bin to /tmp

/tmp # mtd_write write /tmp/firmware.bin Firmware_Stub
Unlocking 'Firmware_Stub' ...
Writing from '/tmp/firmware.bin' to MTD 'Firmware_Stub' ... [ok]

Let me know if that works for you:) i will try this maybe later on :slight_smile:
cheers Michal

ok now testing on my own fresh build from Today.

@craz
Same as before. I can connect my PC but iPhone can't connect to 2.4Ghz.
But now iPhone says invalid Password ....

5Ghz is working. But why on some Channels the raido1 is offline.

I tried many things, build an image without ipv6 support, or removing many thing, get intermediate commits, but nothing is changing. I'm fed up with this :confused: If you have any clue.

I have 2 wifi network, simple configuration.

563

ok, iPhone is able to connect after 1/2 hour later.

IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)

persists.

565

@craz
does the Nossiac driver work for you ?

ok, i removed all mt76 stuff in menuconfig and enabled all MTK options.

if i change somthing and press Save & Apply system freezes.

if i load mt7612 i got:

You are absolutely right! Thank you

Or try directly:
https://d.miwifi.com/rom/ssh/download?sn=XXXXX%2FXXXXXXXX&userId=YYYYYYYYYY

replace before XXXXX and XXXXXXXX by your router serial number (found on your router web User interface) (Format XXXXX/XXXXXXXX)
YYYYYYYYYY by your Mi account id (found on account.xiaomi.com)

edit: use before the below address in order to get the root password.
https://d.miwifi.com/rom/ssh?userId=YYYYYYYYYY

Extrem helpfull .....

Means i compile and Test new versions ......

568

I've flashed todays build and no luck :frowning:
Still getting AP-STA-DISCONNECTED after 10 minutes of usage.

Did you try with "option powersave '0'" ?

570

No, its too late. Im on Padavan now and it looks more stable than LEDE. Ill make some tests this week with 10+ clients.

i will test it

You have it wrong, disassoc_low_ack has to be in 'wifi-iface' section.
