Hm. Something seems wrong with the device at USB layer. Does it work with any other driver/OS?

Hm. What is the platform (CPU)? Where did you get the firmware from? Is there chance you could try to compile the driver from Mediatek's website?

Ah, I think they may have removed it after I upstreamed this driver...
You can find some copies on GH, like this one: https://github.com/porjo/mt7601u
As far as FW goes, can you re-download it to make sure it's not corrupted? This is the MD5 sum it should have:

$ md5sum /lib/firmware/mt7601u.bin 
696cedb8e76ecc0cda9f9b0d3972c64d  /lib/firmware/mt7601u.bin

Hm. Looks like the vendor driver doesn't build for 4.9 kernel.
What about the firmware? Could you show what md5sum the firmware you got has?

The problem is in mt7601u_phy_init > mt7601u_init_cal > mt7601u_mcu_calibrate(dev, MCU_CAL_RXIQ, 0). With this lines commented initialization ends successfully and interface appears. Don't know is it working or not.

@jrfabio, I want to solve this problem because I also have mt7601u based device with the same symptoms, so I believe @kuba-moo will suggest some way :)

@kuba-moo, should I open another issue?

Hi @aleksander!
Thanks for investigating, did you check if the device works with calibration removed?
Now we have two bad devices, perhaps we can try to find commonalities. What's your dongle Aleksander? @jrfabio how about yours?

Yes, device works without calibration. I successfully connected to my phone and loaded some web sites. Not sure about speed and stability though. Need more testing.

What's your dongle Aleksander?

Mine is Elisona USB Wi-Fi adapter ordered from aliexpress (https://aliexpress.com/item/150Mbps-Mini-Wireless-USB-Wlan-Adapter-802-11g-n-Wifi-Dongle-Lan-Card-w-Antenna-big/32527991067.html)

if this help I can dissassemble the device to see whats in there.

I still can't find a cd-rom to check CD contents, maybe I'll find modified driver there.

I think the chip reports to be the same version of silicon as all the others I've seen (well there are two variants but this is the more common one). I will try to get one from AliExpress, although it will take a month to be delivered ;)
Definitely check out if there is a Linux driver on the CD. The version of Linux driver I had from MediaTek was quite old, perhaps they changed something.

Look like it's the same old mediatek driver.

3.0.0.4 is the version I was basing this driver on :( One thing you could try to do is installing a very old kernel (~3.8 times probably) and see if the vendor driver works there. For now I think you should be safe to hack the calibration out, I think it only affects sensitivity.

which version of kernel you use? if >=4.2 just do as follow ,it works for me. just try it.
I repaire this on my pull request 。 or you can just add follow code to you proj in mt7601u.h。
//just for kali 2018.2 kernel version >4.2
#define RX_FLAG_SHORTPRE (1<<8 )
#define RX_FLAG_HT_GF (1<<13)
#define RX_FLAG_HT (1<<9 )
#define RX_FLAG_SHORT_GI (1<<11)
#define RX_FLAG_40MHZ (1<<10)
#define RX_FLAG_STBC_SHIFT (26)
and commit this code in usb.c 128 line.
//mt7601u_vendor_request(dev, MT_VEND_DEV_MODE, USB_DIR_OUT,MT_VEND_DEV_MODE_RESET, 0, NULL, 0);

so
enjoy. but the drive have a bug , it is not so good,so if you want a short delay in ping echo. if i have time,i will repaire it ,later.

It works! THX

Here's a funny deal :
My device works fine with no compilation whatsoever required on Ubuntu 18.04.1 (kernel : 4.15.0-38-generic). It does not work (connect to networks) with Debian 9.5 (kernel : 4.9.0-8-amd64)
Initially, lsusb would recognize the device, show me the right information about it; lsmod showed that the kernel module required to make the device was loaded. However, it wouldn't show up in my WiFi network settings.
Upon one of my reboots, I noticed an error log saying that it couldn't load the firmware for the device. I looked in /lib/firmware and the firmware was indeed missing. I simply copied the firmware file from my Ubuntu installation directly into my Debian installation (both of the OSes reside on the same hard-disk; for privacy sanity reasons); checked the md5sum of the copied file as mentioned here (it checks out).

My problem is that the device works fine until the point that it has to connect to some network. It detects long-range networks (networks that my crippled internal wireless card can't) but it just wouldn't connect to any network. Even the hotspot from my phone that is sitting practically next to the computer. My internal wireless card can connect to that one at least (just not a router that is sitting in the next room).

I don't think it's something to do with the driver, since the device works fine on my Ubuntu installation (considering there hasn't been any changes to the driver since 2016 up until kernel version 4.16).

I find this in dmesg :

[  624.997557] mt7601u 1-1.3:1.0: Error: RX urb failed:-71

Is there something that I can do to debug this issue on my Debian installation? I also know that these are the problems that accompany free softwares like Debian but I don't want to use Ubuntu exclusively. Please help.

I could try building; but I have to say that I haven't done this before though. I might mess something up in the process. :/ I'm not sure. I can get back after some playing around with the kernel.
Apart from that, is there some easier way other than compiling / building the kernel from source? (I think the kernel source alone is >2GB and after compilation it would probably be around 4-6GB)
Also, I don't want to mess around with my actual operating system, so, I have to try it out on a virtual machine which wouldn't actually emulate the actual scenario for me. The other option is to find a broken laptop that isn't exactly usable, but in working condition that I can compile kernels as much as I want and see how it goes. That's not practical for me either. Hence, I'm asking for some other easier alternative.

The solution described here worked for me in Ubuntu 16.04 and 18.04:
#64 (comment)

I will reference it here:

Originally written by ingate.
Thanks to aleksander and Nidroide.
Tested on Ubuntu 14.04 (kernel 4.4), Ubuntu 17.10 (kernel 4.13) and Ubuntu 18.04 (4.15.0-36-generic)

  1. Download corresponding kernel source from kernel.org. For example: if you have 4.4.0-104-generic download version 4.4.
  2. From archive unpack just folder drivers/net/wireless/mediatek/mt7601u
  3. Edit phy.c. Find function mt7601u_init_cal and comment out call mt7601u_mcu_calibrate(dev, MCU_CAL_RXIQ, 0); like so:

// ret = mt7601u_mcu_calibrate(dev, MCU_CAL_RXIQ, 0);
// if (ret)
// return ret;
// ret = mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->dpd_temp);
// if (ret)
// return ret;

Find function mt7601u_phy_recalibrate_after_assoc and comment out call mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->curr_temp); like so:

void mt7601u_phy_recalibrate_after_assoc(struct mt7601u_dev *dev)
{
// mt7601u_mcu_calibrate(dev, MCU_CAL_DPD, dev->curr_temp);

mt7601u_rxdc_cal(dev);

}

  1. Build module: make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
  2. Remove device
  3. sudo rmmod mt7601u
  4. sudo insmod ./mt7601u.ko
  5. Insert device
  6. Check there are no errors in dmesg and interface appeared in ip link, check connection stability.
  7. To make change persistent till next kernel upgrade: backup original module and replace with compiled. To find out where is original module run modinfo mt7601u (view string filename: /lib/modules/KERNEL_VERSION/kernel/drivers/net/wireless/mediatek/mt7601u/mt7601u.ko).

Does it works without commenting CAL_RXIQ ? Vendor driver does DPD calibration under conditional compilation, so perhaps it should be disabled on some devices based on USB ID or some EEPROM flag. But it always does RXIQ calibration .

I have follow the comment: ### pedrombmachado commented
It can work 5 minutes .After 5 minutes it report:
mt7601u 8-3:1.0: Error: RX urb failed:-71
and disconnect the wifi.
The small dongle is hot.

I change another mt7601u dongle . The dongle have a External antenna(The two mt7601u is not one manufacturer). It is hot too. But it can work fine with ubuntu 16.10 and ubuntu 18.04
I think, the driver is work fine normal , but chip is work instability. When Temperature rise. It lost some data, and the error process have bug in it. The error process It should have re_init the dongle, but it close the network.So If someone check the error process, maybe will fix it.( Just guess )

@qinchuan12345 does the driver not work for you if you don't use changes from previous comments ? MCU_CAL_DPD is exactly for temperature calibration so maybe dongle overheat because of that calibration removal.
You can also compile with debugging enabled by this patch
enable_debug.patch.txt
and provide dmesg output. It should show more what happen before RX urb failed error.
