Omega2: WiFi Client with Lede Image



  • @Nikolay-Hristov https://github.com/noblepepper/mtk-wifi itself is not a feed, but just one package from a feed. So you can't directly use it as a feed url.

    So what I did was copy the mtk-wifi folder into the folder of my own feed in lede/feeds. Then I ran

    ./scripts/feeds update -i plan44
    

    to index it, and then it can be installed

    ./scripts/feeds install kmod-mtk-wifi
    

    Then start menuconfig to enable it for build, it's under "Ralink SDK Mango" in the menu.
    Finally, built it with

    make package/mtk-wifi/compile
    

    Please let us know when you manage to configure it as client :-)

    Along with the mtk-wifi driver, the package also brings a utility shell script called widora_mode. It supposedly creates the correct config for different wifi modes such as access point, bridge, client. I got my Omega2 work as client immediately after typing widora_mode client MYSSID mypassword. However, after restarting the Omega, the WiFi does not connect again.
    I don't understand that, because all widora_mode does, is issuing some UCI commands to modify the /etc/config/network and /etc/config/wireless, and then call /etc/init.d/network restart. I would have expected that config to still work after reboot.



  • hm, am I doing something wrong?
    I have cloned https://github.com/noblepepper/mtk-wifi to feeds/mtk-wifi:

    lede@bender:~/dev/lede-project/lede$ ./scripts/feeds update -i mtk-wifi
    lede@bender:~/dev/lede-project/lede$ ./scripts/feeds install kmod-mtk-wifi
    WARNING: No feed for package 'kmod-mtk-wifi' found, maybe it's already part of the standard packages?

    it didnt show in make menuconfig menu..

    Sorry but I'm not (yet) familiar with the openwrt/lede build process



  • @Nikolay-Hristov said in Omega2: WiFi Client with Lede Image:

    I have cloned https://github.com/noblepepper/mtk-wifi to feeds/mtk-wifi:

    The individual packages need to be one level deeper than just feeds, meaning you need to have a folder like feeds/myfeed and clone mtk-wifi into that folder as feeds/myfeed/mtk-wifi

    You could probably hijack one of the existing feeds (onion's for example) and just plant mtk-wifi there as a cuckoo's egg ;-)

    But I can only recommend having an own feed for these types of experiments - essentially just a git repo somewhere of which you put the url into feeds.conf.default. Then you can copy packages to examine/modify there. As scripts/feeds install allows to specify a preferred feed, you can even copy packages from another feed to your own to develop and test modifications. I do this with omega2-ctrl, because @onion still hasn't found the time to process the pull request [Update: no longer, @Lazar-Demin just merged the PRs, thx :thumbsup: :-))



  • Hi @Gerhard-Bertelsmann, @james-lee, @Nikolay-Hristov and everybody else trying to get reliable WiFi with LEDE: Great news - just forget about mtk-wifi (and freezing kernel versions because of it)!

    Latest commits from today (e209988) on lede-project master seem to fix the reliability and performance issues with the open source mt76 driver!

    The commit messages looked very promising, so I just rebuilt my project's image based on today's LEDE master, installed it, rebooted, and - WiFi just works! Not a single "wlan deauthenticated" message in dmesg any more. I haven't really tested in depth, but performance also felt normal scp-ing a firmware image to /tmp.

    Really cool! :-D



  • @luz Hi. Tried to build image on Ubuntu 16.04 but make menuconfig behaves strange.
    e.g. can't see cursor if I resize terminal.

    Do you have such problems or you are using imagebuilder/edit config by hands?



  • @M-S192 I'm using LEDE buildroot on macOS (in a case-sensitive disk image), and menuconfig works fine with the standard Terminal app.



  • @luz I've got it up and running but still not even close to stable wifi... i cant connect it in STA mode, only in AP mode
    it works but when I do:

    iw wlan0 scan

    I'm getting MCU errors and then module crashes:

    so... not stable :(



  • @Nikolay-Hristov :-(

    For me, station mode works fine (and definitely did not before these commits from yesterday). I did not try iw wlan0 scan yet, but just set my SSID and key in /etc/config/wireless. I'll try scan this evening and let you know.



  • @Nikolay-Hristov [Update] iw wlan0 scan works fine, and ap mode works as well. Not a single unexpected message in dmesg.

    However, in my setup I had rearranged /etc/config/network and /etc/config/wireless a bit as I didn't want the standard router setup, but a pure client. I also have removed odhcpd and dnsmasq packages because I absolutely don't want the Omega to ever become DHCP server and mess up my LAN.
    I don't think that this should affect the mt76 driver level stability at all. But still, for reference, here's my config:

    /etc/config/network:

    config interface 'loopback'
      option ifname 'lo'
      option proto 'static'
      option ipaddr '127.0.0.1'
      option netmask '255.0.0.0'
    
    config globals 'globals'
      option ula_prefix 'fd1d:48c4:7633::/48'
    
    # station mode WiFi
    config interface 'wlan'
      option proto 'dhcp'
      option hostname 'pixelboard-WiFi'
      option enabled '1'
    
    # Ethernet
    config interface 'lan'
      option ifname 'eth0'
      option proto 'dhcp'
      option hostname 'pixelboard-LAN'
      option enabled '1'
    
    # AP mode WiFi
    config interface 'wlanap'
      option proto 'static'
      option ipaddr '192.168.44.1'
      option netmask '255.255.255.0'
      option enabled '1'
    

    /etc/config/wireless:

    config wifi-device 'radio0'
      option type 'mac80211'
      option channel '11'
      option hwmode '11g'
      option path 'platform/10300000.wmac'
      option htmode 'HT20'
      option disabled '0'
    
    config wifi-iface 'ap_radio0'
      option device 'radio0'
      option network 'wlanap'
      option mode 'ap'
      option ssid 'PIXELBOARD'
      option encryption 'none'
      option disabled '0'
    
    config wifi-iface 'cli_radio0'
      option device 'radio0'
      option mode 'sta'
      option network 'wlan'
      option ssid 'MYSSID'
      option encryption 'psk2'
      option key 'MYPASSWORD'
    

    The only problem I currently have is that disconnecting ethernet does not automatically remove the route for eth0, so if eth0 and wlan0 go to the same subnet, wlan answer packets might get routed to the disconnected eth0.



  • @luz Many thx for your updates. Great News. However I didn't get it working so far albeit I hadn't much time to check my setup. I going to take your Settings (network&wireless) and see how it goes ...



  • I've tested it more and I can say - yes, there is a significant improve in stability on open source driver. I still have some problems but it is a good step in the right direction. Will test it more and then report here.



  • I am still getting kernel call traces with the latest driver and batman-adv.. so not stable yet :(

  • :-( indeed.

    But then, batman is already quite advanced WiFi usage.

    Still, could be worth posting the trace to LEDE forum.



  • I'm directly interested solving this problem. However, the open source driver may take a while until it gets fully reliable. I would still focus on integrating the proprietary driver.

    The interesting part is that the Linkit Smart OpenWrt image does include the proprietary wifi binary. I'm trying now to build a stripped image and have it put in Omega2. There are still some build errors (like renaming the wifi binary from *.44 to *.45 as the kernel version goes).

    https://docs.labs.mediatek.com/resource/linkit-smart-7688/en/tutorials/firmware-and-bootloader/build-the-firmware-from-source-codes



  • @Cezane just to say, not sure but I think I've read somewhere that propriety driver does not support ad-hoc mode. Is that true?



  • It seems to me that there are two different proprietary drivers. I can deduce this from two different types of configuration that I've encountered, with Omega and with LinkIt Smart. I'm personally interested in having a reliable AP and Sta at the same time. The driver from LinkIt can support AP, Sta and AP+Sta. Haven't found anything related to ad-hoc mode...



  • Yay! With the LEDE image, my Omega2+ connects to my Mikrotik router. Finally I can start developing on this months after receiving it.

    onion.io devs: Please fix your wireless drivers so I can come back to your images. I shouldn't have to use the LEDE images just to get wifi out of the box. You've got a great product here but it's hindered by this problem.
