#14

I have one, but unfortunately I won't have access to it for a while so I can't test anything myself.

#15

I resolved this issue with Padavan's firmware https://bitbucket.org/padavan/rt-n56u

I highly recommend everyone to try Padavan's firmware. You will never back to OpenWrt/LEDE version.
Of course, I can control USB2.0/USB3.0. Everything works great!!! No more problems!

Hi,

I have then tried PandoraBox. Well wifi is better than Padavan and better than OpenWrt.

I have also a Xiaomi 3, i changed that to PandoraBox due to use of propietary drivers.

It's a pitty OpenWrt can not use those drivers as it has the best support/plugins.

Ciao
Attaros


#19

Hey,
can you tell us how to install PandoraBox? Which version do I have to install and how does it work? Via sysupgrade or is there anything else I have to do?


#20

Does anyone have the same Problem as me?
After flasing OpenWRT and connecting my routers lan to the wan port of the mi wifi3g I can activate Wifi and its working. But when I turn off the power and turn it back on I cant get internet access over Wifi anymore and it never comes back. I am trying since 10 hours and I really do not know what to do anymore.

Start by posting the system and kernel log after a reboot. My first thought is that there's a problem with the flash memory, resulting in a broken config file. That has caused several similar problems on this router.

Wifi at 5GHz is unstable at 18.06.1 . I built from source yesterday a new firmware and nothing changed. The picture i attached shows the problem. Every couple of minutes the connection drops. I tested with 3 devices and they reproduce the same behavior therefore the router is the causing of the problem. This behavior was present 6 months ago when i first build and install the lede firmware. I hoped over the time to improve. I guess we should inform the developer of the wifi driver. Reporting here seems the like wrong place for things to be fixed.drop_packages

Edit: I must also mention the test conditions: The router is 3 meters (10ft) away from the receiver. There is no other station at 5GHz and im nowhere near any airport. I used iperf3. Sending from the router to the device there is a faster connection around 200Mbs yet there is a lot of drop packages every couple of minutes. Sending from the device to the router the connection is more stable with only maybe 30 to 50 packages lost every couple of minutes. Yet the later is slower for some reason around 130 to 150Mbs.

#24

Did you try compiling without USB3 support like Carp did earlier in this thread? Unfortunately he was not successful in using other USB drivers instead.


#25

I don't use the 2.4GHz band, so i didn't care that much about USB. Out of curiosity i decided to omit usb all together from the kernel. The results strangely enough got worst.drop_packages_bo_usb
Now i loose packages constantly, have lower speeds and still have disconnects, less frequent though. That was weird enough to got me revert to the previous firmware so i could eliminated the environment factor.drop_packages_with_usb
So reverting i got the old behavior. Im not convinced that the usb have such a dramatic effect, yet is the only thing i changed. Hmmm ....

Hi,

I suggest always to go to Stock before chaning to Padvan/OpenWrt/Pandora.
OpenWrt -> Stock -> Pandora

When i was on OpenWrt i first updated the "bootloader" to "breed". This then makes it easy to go to Padvan/OpenWrt/Pandora/Stock. Search the Web for instrunctions on Breed

To update "bootloader" while i was on "OpenWrt" i did as below.
Connect via ssh to the router:

cd /tmp
mtd_write unlock Bootloader
wget --no-check-certificate https://breed.hackpascal.net/breed-mt7621-xiaomi-r3g.bin
mtd_write write breed-mt7621-xiaomi-r3g.bin Bootloader
mtd_write verify breed-mt7621-xiaomi-r3g.bin Bootloader
reboot

If you miss mtd_write then you can:
SSH to the router, and execute the command:

opkg update
opkg install kmod-mtd-rw
insmod mtd-rw i_want_a_brick=1
mtd unlock /dev/mtd0
mtd -r write /tmp/breed-mt7621-xiaomi-r3g.bin Bootloader
reboot

To flash with "Breed":
Before the power on, press and hold the reset buttom until the light blinks stable.
Now you should able to access the BREED interface though browser 192.168.1.1

Why are not there any developers fixing 2.4 g wi-fi in this modem? It is always connected and can not be reconnected if the legacy rate is only 10 megabits per second


#28

Can not customize the Tx power option 2.4ghz


#29

I am using the test and quality 2.4G wifi extremely bad, 20mhz is 6 Mb, 40mhz is 54Mb, wifi always disconnected automatically, too disappointed :frowning:

#30

I just saw an update for mt76xx,
But there is no improvement in the 2.4ghz band :disappointed_relieved: :sleepy:

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=4fd9a5667eab6a75d8c3b7a1510dfb354ecca969


#31

Please note that MT7621 doesn't come with either EHCI or OHCI controller, both USB2.0 and USB3.0 are controlled by its XHCI. Thus if you disable XHCI you disable USB completely.
If you want to force USB2.0 mode, just plug your USB3.0 device halfway into the USB port at some point where USB2.0 pins are connected while USB3.0 pins are disconnected.


#32

Interesting, but then how does the Padavan firmware force USB2 mode?


#33

It's a parameter passed into the XHCI driver module

At trunk/linux-3.4.x/drivers/usb/host/xhci.c line 49:

int usb3_disable = 0;
module_param(usb3_disable, int, S_IRUGO | S_IWUSR);
MODULE_PARM_DESC(usb3_disable, "Disable USB3 interface");

And it disables USB3.0 port power if usb3_disable is set
At trunk/linux-3.4.x/drivers/usb/host/xhci-hub.c line 838:

			if (usb3_disable && hcd->speed == HCD_USB3)
				xhci_writel(xhci, temp & ~PORT_POWER, port_array[wIndex]);
			else
				xhci_writel(xhci, temp | PORT_POWER, port_array[wIndex]);

How to disable usb 3.0 in driver to avoid 2.4GHz interference?
#34

Here, I made a patch to force USB2. It's very basic and can't be configured. Someone more experienced should mainline this.

How to, by building your own image:

USB and 2.4Ghz works fine for me now !
Thanks to LGA1150 for the detailed info :slight_smile:
