mac80211 driver for MediaTek MT76x0e, MT76x2e, MT7603, MT7615, MT7628 and MT7688

mt76's Issues

Performance of Open Driver vs MTK Closed Driver

We've been looking at the performance on the MT7688 based Linkit of this open driver relative to the original closed driver provided by MTK.

Using iperf we get ~40Mbps of tcp performance on a local network.
DUT - wifi - AP - ether - LAPTOP

The identical network and hardware setup with the open driver gets lets than 1Mbps (if that).Sometimes with significant stalls etc.

This is with #28 applied.

Just wondering if others see the same poor throughput performance?

does mt76x2_eeprom contain invalid values?

looking at the code i see there is quite some defines missing, and some are possibly wrong!

for example:

MT_EE_LNA_GAIN =          0x044,
MT_EE_RSSI_OFFSET_2G_0 =        0x046,
MT_EE_RSSI_OFFSET_2G_1 =        0x048,
MT_EE_RSSI_OFFSET_5G_0 =        0x04a,
MT_EE_RSSI_OFFSET_5G_1 =        0x04c,

this would mean the data for chain 0 are not read since in my factory eeprom this field is 00. it is also wrong name RSSI_OFFSET for what the driver assumes it works with but it should be renamed to LNA_GAIN

according to MT7612E EEPROM content guideline

it should be:

MT_EE_LNA_GAIN_2G =           0x044,
MT_EE_LNA_GAIN_5G_GROUP1 =      0x045,
MT_EE_RSSI_OFFSET_2G_0 =        0x046,
MT_EE_RSSI_OFFSET_2G_1 =        0x047,
MT_EE_LNA_GAIN_5G_GROUP2 =      0x049,
MT_EE_RSSI_OFFSET_5G_0 =        0x04a,
MT_EE_RSSI_OFFSET_5G_1 =        0x04b,
MT_EE_LNA_GAIN_5G_GROUP3 =      0x04d,

Plans to support MT7628 ?

IDK if this works for this:

SD card issue in MT7620

I have a ZBT-WE826 router with built-in SD Card slot. I am trying to mount my SD card in my Router. I've openWRT CC with kernel 3.18. I've download mmc_over_gpio and related packages.. But the problem arises, when I run "/etc/init.d/mmc_over_gpio restart", i get this error "no support for SD card's voltages" ..
There is also a ticket open in openWRT for this on, "https://dev.openwrt.org/ticket/21834" ..

How can i solve this error?? i tried multiple SD cards, but no use..

mt76x2 led control (is work)

mt76x2_mcu.h
..........................................

define MT_MCU_LED_CTRL 0x0770

.........................................

so..........................

mt76x2_init.c add

LED ON
mt76_wr(dev, MT_MCU_LED_CTRL, 0x800000);

LED OFF
mt76_wr(dev, MT_MCU_LED_CTRL, 0x820000);

LED TX BLINK
mt76_wr(dev, MT_MCU_LED_CTRL, 0x840000);

MT7688

I'm trying the changes to support MT7628/88 and have been successful in getting AP working, but can't for the life of me get STA working.

Are there any known issues with STA on this chipset? I notice I can't even scan for networks.

missing Efuse defines

there is no defined EXT_EE_SEL pin in eeprom.h so no way to choose between Efuse/EEPROM

maybe mt76 led control solution

form here http://www.itdadao.com/articles/c15a53935p0.html

LED2_KICK = 1 , LED2_POL = 0 , LED ON (LED_CTRL write 0x800000)
LED2_KICK = 1 , LED2_POL = 1, LED OFF (LED_CTRL write 0x820000)
LED2_KICK = 1，LED2_TX_BLINK_MODE , LED BLINK (LED_CTRL write 0x840000)

test command
cd /sys/kernel/debug/ieee80211/phy0/mt76

Broken 5G signal connections

Use mt76 turn 5G signals will break down automatically every 5 minutes.

Supporting MT7610UN as well? (AVM USB Stick AC430)

Similiar question to #5
Would this be suitable for the abgn+ac usb wifi stick AC430 from AVM?

Support for ASUS USB N53 B1 dual-band wireless adapter?

I've filed an issue with @kuba-moo about getting support with this device, which I think has an MT7662 chipset. I didn't know about your work until @kuba-moo told me about it.

Device hang after load firmware.

I'm porting openwrt to a MT7620A+MT7612
E board. But my board hang after load firmware, and no respond.

MT7688AN relay mode, I get oops

Now I use mt76 to connect to a AP that is used as a relay. Find two questions:
1, the speed is very slow, I try to use Ping AP superior MT7688, and sometimes a lot of time delay:

DFS / ACS errors

enabled auto channel selection and got log spammed with

radio0 (4025): ACS: Survey is missing noise floor

ACS seems to be working fine

except that i'm not sure about sec_chan=1

shouldn't it be something like 56?

and according to this message HT not enabled (maybe it doesn't catch it's actually running VHT80?)

MT7603 driver crash (wg3526)

Hi,

The driver MT7603 provokes random network crashes, on ZBT-WG3526. When using the wifi chip it randomly provokes complete network failure, including wired network. After a crash I cannot connect the the device in SSH anymore because the Network does not work anymore.

I often get warning messages like this one, during normal use:

PA not properly engaged on Xiaomi mini

all test so far indicate that power amplifier on this device doesn't function.

with stock fw power level is between 80 and 90% on ubuntu notebook but with openwrt about 50-60% if the power isn't raised in chip directly with 1413f55

the information available in MT7612E datasheet suggest to enable GPIO 13 and 14 in IO_MODE 7 for PA to work.

can someone implement this in driver code?

Does this driver work for MT7620A

Hi there, does this driver work for MT7620A? Or should I use mtk-wifi-gpl or rt2800?
I also have rt2860v2 driver, which we bought from the licensed module vendor. Somebody leaked it here. Do you know which one is the best Wi-Fi driver for MT7620A?

if the mt76 driver support mt7602e?

if the mt76 driver support mt7602e?

why my mt7602e device not work?

[Q] Support for LED(s)

Hello,

I have a device based on MT7621AT with MT7602EN and MT7612EN. I have almost finished support for it in OpenWrt, but I don't know how to control LEDs for both radios.

They are connected directly to pin 50 on both MTK radio chips (I have found that it's GPIO/LEDA I/O, at least in MT7612E, I wasn't able to find information about second chip) and are "active in low" (connected to VCC over current limiting resistor).

How does it look with that kind of setup, is control of LED/GPIO I/Os supported (or planned) in mt76 driver (I wasn't able to find anything specific in sources)?

Thanks for any advice!

(mt7603/76x8) Why do we apply cal free data when calibration exists?

When using on mt7628 or mt7688 devices cal free data is applied after loading the calibration data from the factory partition.

This greatly reduced throughput and caused frequent re-associations on some boards. Commenting out the cal_free_bytes list in mt7603_apply_cal_free_data gave almost 40x improvement in throughput and eliminated the re-associations. This is obviously not the correct solution since it would break boards without calibration partitions, just evidence this is the source of the issue.

MT76 Kernel Warning (two cases)

I using MT7621A base board(7603E + 7612E)
It has ePA + LNA, but mt76 seems can't support it.
(MTK openwrt can't support too. But MTK SDK can support normal through)

Is it normal?

bad reception throughput

i've noticed that with recent commits reception speeds are pretty low. for comparison i've used previously compiled images and the speed drop increases as the image being tested gets newer.

WiTiBoard 2GHz wifi too slow

Current LEDE master compiled for WiTiBoard gives slow 2GHz wifi (MT7602E)
I have configured N mode through Luci on 20MHz (channel 11), but download speed is 2.5 MB/s at most.

High packet loss when changing mac address

This was actually a report on the IRC in #linux-wireless. No answer from nbd was received (yet) so this is just to keep track of it. The relevant part of the message is the "second thing"

nbd: d0tslash bought two of these witi boards which you've recommended for the mt76 evaluation.
problem right now is the extreme packet loss (the AP is basically not usable for 2.4GHz/5GHz). this seems to be related to two different problems
first there are only two connectors (4 are required for the 2x2 setup on 5GHz/2.4GHz)
and do you know if there is a way to disable a chain on the device so I can avoid some of the (minor) performance problems?
The other second things seems to be related with the mac addresses in my multivap setup. I am defining multiple APs (and IBSS) devices in my default setup
each of the devices has a different mac set. for example @option macaddr 'ac:86:74:00:00:c2'@
but even only enabling 1 AP per device but with a changed mac seems to cause these packet losses
an example config (sry, didn't make it really clean) can be found under https://gist.github.com/ecsv/b6c42f07e1da6cc2ea41fe72fa5fe4d3
is this a known problem with mt76+these chips? the used LEDE version is reboot-393-gaf1e70b. If not then I can also report it at the proper place (github mt76 issue tracker?)
I haven't yet checked any over-the-air traffic and I doubt that I will be able to do so today (have to leave in some minutes)
just in case it is related to the initial mac of the device. phy0 mac is 00:00:00:00:00:20 and phy1 is 00:00:00:00:00:b8. yes, this looks bogus as hell but haven't yet checked how the dts sets the source of the mac for this device

Problems receiving ARP

Openwrt Version: HEAD (17/3-2016)
mt76: 7059cc2
Kernel: 4.4
Hardware: MT7688 (LinkIt)

After hacking the device tree the driver is functional :-)
But ARP requests are not getting through.
If I look in mac80211.c/mt76_rx_complete I can see that some broadcast packets but not all are getting through.
This might be a firmware issue or just missing configuration.
Any idea on how to track this bug down?

Regards

Jakob

Issue with iPhone 6S and MT7603

Hi,

I have a router with mt7621 chipset and an mt7603/mt7612 wifi combo. The image I am using is built from OpenWRT trunk and has kernel 4.4 + all the latest mt76 and mac80211 fixes/changes. The mt7612 (used for the 5GHz) is working perfect, but I am having some issues with the mt7603 and an iPhone 6S. There might be other devices experiencing the same problems, but I dont have any available.

When I initially connect the iPhone to the 2.4 GHz wifi (i.e., the mt7603) everything works fine. However, when the phone has been idle for a while and tries to reconnect, something goes wrong. When looking at the settings on the phone, I see that it has acquired an IP and this seems to match the output in syslog. However, no traffic goes through. It seems that the traffic sent from the phone is dropped somewhere. I also see the following warning in dmesg (not sure if it is connected or not):

This error does not happen every time the device has gone into idle mode. I unfortunately do not have access to any device where I can sniff the wifi traffic, so I won't be able to provide any of those details. I hope this issue can serve as a starting point for nailing down this bug. I have tested the 2.4 wifi network with other devices too, like my laptop, and do not see the issue.

Thanks in advance for any help.

Use proper commit logs

Please, please try to improve the commit log. I'm currently looking at an issue and looking at the log is USELESS. All commit are just a short "fix X and Y" without any description of the problem fixed or what the fix is doing. I do hope the authors known what they are fixing, but this completely prevents others from tracking issues. Furthermore it make it hard for new developers to start working on the project as no explanations of the changes can be found in the log.

I known this can't be fixed for old commit, but in the future please try to adhere to the usual community standards and take a few minutes to write proper log messages. This will drastically improve the maintainability of you project and make it a lot easier for new developers to join.

Set WiFi 5G channel to 52 or later will disable wifi

Hi, my board wifi chip is using mt7621,7603.

I've updated my openwrt mt76 driver to "mt76x2: dfs: remove unnecessary memset(62abac9)"

and add patch for bitfield.h so that I can build succeessfully.

I test wifi 5G channel by the order: 36,40,44,48,52,56 ...

However, when I changed to channel 52, wireless webGUI shows "Wireless is disabled or not associated".

Does the dfs malfunction?

Below is my dts configuration:

&pcie {
status = "okay";

    pcie0 {
            mt76@0,0 {
                    reg = <0x0000 0 0 0 0>;
                    device_type = "pci";
                    mediatek,mtd-eeprom = <&factory 0x8000>;
                    mediatek,2ghz = <0>;                       
            };
    };

    pcie1 {
            mt76@1,0 {
                    reg = <0x0000 0 0 0 0>;
                    device_type = "pci";
                    mediatek,mtd-eeprom = <&factory 0x0000>;
                    mediatek,5ghz = <0>;                        
            };
    };

};

and the console log just like:

Compile Issue with openwrt linux version 3.10.14

Hello Team, I am trying to cross compile mt76 driver for ZBT device MT7621 using medeiatek SDK.

package details:
PKG_NAME:=mt76
PKG_VERSION:=2016-06-17
PKG_SOURCE_VERSION:=f06ed811cda67ab2ed9932c3e87ba03229e75f4e

But seems it is not compatible with kernal version 3.10.14.
Can some one help me out for compilation issue?

Following are the compilation error:
