Say, hi fi to everybody!

Driver "mt7601Usta"(DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2) for the MediaTek MT7601U based wireless adapters - on a sale worldwide, is broken and obsolete. MediaTek folks,
please consider the release of an upgraded version of the driver for the current stable Linux kernel, and the upcoming.
Thanks.

These are the results of tests starting with:

It would be much better if the MediaTek folks would just send us patches for the drivers already in the kernel...

No. Sorry. The existing rt2800-driver is mostly broken and unusable compared with the original Ralink drivers. Especially the usb drivers are extremely bad. There are huge differences between the ralink usb drivers (rt5572sta e.g.) and the rt2800usb driver. The ralink drivers are working fine with a few additional patches even with kernel 3.15 and with 64bit(!!).

@MediaTek
Please provide own drivers as before as the existing rt2800 drivers should be reworked completely - but from my point of view they are dead since long time now.
It is much better to have one basically good working driver (which must be patched manually to work with newer kernels because newer kernels often aren't downwardly compatible - if they would be, there wouldn't be any problem even with older drivers. But this is a huge problem of Linux at all).

Regards and thanks to Ralink / Mediatek for providing own drivers! Andreas Hartmann

Regards and thanks to Ralink / Mediatek for providing own drivers!

No. Sorry. They are doing the wrong thing. If Ralink/MediaTek would cooperate with the community and work through the normal kernel process like everyone else, their hardware would be fully supported out of the box just like hardware from other vendors. Then no one would have to bother with figuring-out how to get the driver "working fine with a few additional patches", whatever that means.

By apologizing for them and degrading the rt2800 driver you are only making things worse. You should demand better behavior from MediaTek.

A patch[1] is composed partly from the RT3573 source code patched by ashaffer, from Andreas work, some of the ideas are from the beagleboard community, and some of my. :) Debug(trace) is turned off.

Device now works more or less OK but slow, max. 10 Mbit, although connectable is only within the "N" & "N/G" modes. What is important is the system no longer crashes, and disconnection are rare.
Generally better than before.

Tested with kernels:
3.15.10-200.fc20.x86_64
3.16.1-301.fc21.x86_64
3.17.0-0.rc2.git0.1.fc22.x86_64

and with debug kernel:
3.17.0-0.rc2.git1.1.fc22.x86_64
dmesg:
...

A new patch[1] mainly based on patches at
https://github.com/ashaffer/rt3573sta
and several network throughput tests via the Iperf. Tested with kernels:

- 3.16.1-301.fc21.x86_64
- 3.17.0-0.rc2.git3.1.fc22.x86_64

Thanks for providing test results. With respect to the bottleneck fast ethernet switch in between and that it is most probably a 1x1:1 mimo config according[1], they are fine!

The 64bit patch you attached is fine for use with tunneling, like vxlan, too!

Regards,
Andreas

You probably shold be sending this to MediaTek. The driver you are using is not part of the upstream Linux kernel.

BTW, pán Gruszka, when will these devices be supported as a part of the upstream Linux kernel?

I'm not an oracle :-)

Larry declared to work on some mt76xx chip support, I'm cc him.

I can also work on new chips for rt2x00, but wanted to finish some other work before.
