the code was really a mess... now I can understand why mtk denied to open it.
Sheesh - they made a huge mess of things. I have 840v5 running thanks to @robimarko - it also has mt7628 and sadly the same issues as before.
Flashed, worked out of the box with TFTP on my version. Sadly, WiFi keeps presenting the dreaded issues.
Here is wireless config
config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path 'platform/10300000.wmac'
option htmode 'HT20'
option country 'US'
option disabled '0'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option encryption 'psk2'
option key '704F5738DF8E'
option ssid 'HelloThere-TestingNow'
And here is the log when Clients connect

I also tried with
uci set wireless.@wifi-iface[0].disassoc_low_ack=0
uci set wireless.@wifi-iface[0].max_inactivity=86401
uci set wireless.@wifi-iface[0].skip_inactivity_poll=1
uci set wireless.@wifi-iface[0].wpa_group_rekey=0
uci commit wireless
and lowering txpower to 20 (I read somewhere it has to do with heat),
Less issues, but very very constant too.
On the other hand, stock 840v4 and 840v5 (MT7628) work fantastic.
Please do for mt7603, until it bores you ...
What is the current status of mt7628 working? not working?
I noticed that you committed about it 10 days ago.
Thanks a lot for your work!
PS: I noticed that unfortunately mt7628 was not compiled for Lede stable version (kernel 4.9.92).
PS2:
I also noticed some guy had uploaded the full source to github, hmm, that’s at least not respectiful …
It's at least not respectfull from Mediatek to use GPL software without complying to the GPL, and to sell hardware without software support so...
I've compiled lede 17.01 form source and added your mt7628 driver for 4.4.102 I get the kernel panic enclosed.
As an afterthough I think it's normal because we don't use the same toolchain (you for your module, and me for my kernel), and modules should be compiled with the exact same compiler as kernel. Isn't it?

[ 57.912051] Rebooting in 3 seconds..@nossiac: Thanks for these drivers! I use them for a Linkit Smart 7688 device and they seem to perform better than the opensource mt76 driver. I successfully used the ap and station modes, but only using wpa2. I would now like to connect to an EAP network, but I don't understand how to configure this in the .dat configuration file. Do you know if it that's possible using this driver?
Could someone have mt7628 driver working on lede 17.01.4? I get instant kernel panic, with precompiled drivers.
If someone had it working, please explain how.

the driver has builtin support for all various auth & encryptions.
you can have a try following the source code here:

Thanks! I tried already to configure wpa-eap using the mtk luci plugin, but this seems to be only possible for an acces-point setup. For a client (sta) setup I could not set any radius related options.
This is the config I use with the opensource mt76 driver:
config wifi-iface
option network 'wwan'
option device 'radio0'
option mode 'sta'
option ssid '****'
option encryption 'wpa2'
option eap_type 'peap'
option ca_cert '/etc/ca_cert'
option auth 'EAP-MSCHAPV2'
option identity '****'
option password '****'
Any clues to get this config working using the mtk drivers?
Hi @nossiac , how can we use this in a build environment? What you posted a few days ago, what would be the steps to take?
Haha. well shaiza. Sorry! I'll get to building right away. RTFM FTW.
@amaurynieto @BertL sorry that I don't browse this forum very often.
The drivers I put on github do not work with openwrt's uci config directly, they all use a configuration file named mt76xx.dat, usually referred as "wifi profile", usually you can find it at /etc/wireless/mt76xx/mt76xx.dat. to make the profile work, you should:
ifconfig down -> modify the profile -> ifconfig up
There are 2 ways to integrate the driver with openwrt:
first one is to use luci-app-mtk, it's an independent wifi configuration page for luci, it uses lua script to manipulate the wifi profile, recommended because it's quite easy to extend, potentially powerful.
the second choice is uci2dat, which is a small app that translates openwrt's /etc/config/wireless into mt76xx.dat. thus you may use openwrt's wifi page to configure those drivers.
Hello. So I built it with Buildroot, and booted up 840nv5
It does not see wlan0 nor ra0, it boots up fine.
I do get the following errors on logread... Never mind the initial date, it was before nmap had connected to the timeserver.

The other repo with pre-compiled drivers did not work for me.
Is this stable ? I tried many revsisions of lede but still mt drivers are bad
It seems stable, even if we need to do more tests.
But this repo does not include mt76 driver which is free software and included by default in lede, and still very unstable
I includes a leaked version of the proprietary drive source code (mt7628.ko), therefore It's not very legal. But also it's not a standart linux wifi driver. It has it's own config file, will not work with hostapd or wpad-mini, and will only work in AP mode.
Yeah too bad. It also does not work with tp-link 840 v4/5.
Code need rewrite..
Hello guys, what about this guide? http://rgho.st/private/7sQXBwDCn/78d517e97773daa6e627a9f31664b9b5
Is it guide used to rewrite the driver ?
I found it on https://wikidevi.com/wiki/MediaTek External links for MT7628N
