C2 with wifi module3 not working in Ubuntu

Unread postby spades » Fri Jan 12, 2018 2:16 am

I am trying to get Ubuntu 16.0.4.2 lts running and the wifi does not find my router. I also tried 16.0.4.3 and the same thing.
I have tried everything I know (I am a nooby) and have checked and rechecked several times that everything I typed is correct and still nothing.
I noticed that on first boot the error of load kernel codes showed up but don't know if it relavent?
I have tried DLing and installing several times each time cleaning the card and extracting the DL but still wifi doesn't work.
Could someone steer me in the right direction?
Thanks in advance.

Try the latest image and show us "iwconfig" output on the terminal.

Well I managed to figure out how to get the wifi working but it should not work this way.
I unplug the antenna and wait till the system fails bot ethernet and wifi attempts to connect and then plug it in and it connects.

Another thing I have been wrestling with is the resolution.
I have a Samsung TV which is UHD and when Mate starts the screen resolution goes to 2160 x3840 and is the only one available in the change display area.
I tried to make the change in the boot.ini but being a NOOBY I messed something up and it would not load after a restart.

So I have 2 issues that I cannot resolve and hope someone can help with them?
Thanks

Copy this original boot.ini file into the boot partition and try to modify it again.

You can disable the Ethernet connection on the network manager in Ubuntu.

I copied the file you sent to my device after I reinstalled 16.0.2.3lts and it will not boot now.
I believe I am now having trouble with my SD card and will have to buy another if I decide to proceed.
Thanks so much for your help but I am at a stand still right now.

Ah sorry.
I gave you a wrong link.
C2 boot.ini is here.
https://github.com/mdrjr/c2_bootini/blo ... r/boot.ini

Anyway, I hope your new SD card will solve the issue.

Now I cannot get the wifi to seek and startup on load. And even when I do what I thought, starting up and then waiting for the system to fail and then insert the wifi while system was running, would work even that fails and I have no wifi? I don't know what to try now so any help would be appreciated.

Oh yeah and the sd card still works but only with the raw load of 16.0.4.3 and not with the new boot.ini supplied by Odroid, sorry.

Another thing I find very strange is that I also have a card loaded with Librelec and Kodi and the wifi and my Keyboard/mouse (Rii mini I8+) runs fine.
But when I load Ubuntu it runs terrible in that the it seems like the receiver and keyboard are having trouble communicating. When you move the mouse it stalls all over the screen.
So I thought I damaged the USB ports but that cannot be since it works with Librelec... There were no drivers installed for the Librelec but do I need drivers for Ubuntu? and where are they?

The rest I will try and explain over on the "C2 over heating" thread I started earlier.

As far as I remember, the USB driver in Ubuntu kernel has an issue with low-speed USB 1.1 devices.
Can you show me "lsusb -t" output?

I was able to get this from the terminal. I have now fixed the size problem and have that working so I can see what I am doing on screen.
I am still not able to connect to wifi no matter what I try and do so I hope the below info will give you some insight as to the problem.
Thanks again.
