I'm running 7 compute sticks with Ubuntu 14.04 and they all regularly drop wifi connection. No other devices on our network (about 50 or so) have this issue and stay connected throughout the day.
Any thoughts on why this might be happening?
Sticks are STCK1A8LFC
Thank you for that information.
Let's try updating it to the latest version, 034 is the latest one. See here for the file; https://downloadcenter.intel.com/download/26502/BIOS-Update-FCBYT10H-86A-?product=86613 Download BIOS Update [FCBYT10H.86A].
Let me know how it goes.
Upgrade the kernel, or try a newer distro if possible.
Realtek RTL87xxxx devices have been problematic for awhile: http://www.dedoimedo.com/computers/realtek-bug-fixed-kernel-4-8-7.html http://www.dedoimedo.com/computers/realtek-bug-fixed-kernel-4-8-7.html
I think the one's included in the Compute Sticks are the Realtek RTL8723BS, but I'm not 100% sure...
I'm being an 'armchair technician' with this reply, since I cannot currently try this, but here is some advice that may help: https://selivan.github.io/2017/01/25/linux-4.4-realtek-RTL8723BE-wifi-fix-hanging.html https://selivan.github.io/2017/01/25/linux-4.4-realtek-RTL8723BE-wifi-fix-hanging.html
I get that the Ubuntu distribution and Linux kernel are newer in the above instructions, but the steps should be similar, if not the same. AFAIK the wireless device in that Compute Stick is the Realtek RTL8723BS. So you'll have to alter the instructions to match.
If you're not worried about messing around with the Ubuntu installation, and the possibility of breaking it, you could try it on one of your Compute Sticks, and see what happens.
There's a bit more info here as to what is probably going on, and more tips that could solve it (keeping in mind that your device might not be the RTL8723BE described therein): http://www.dedoimedo.com/computers/ubuntu-trusty-realtek.html http://www.dedoimedo.com/computers/ubuntu-trusty-realtek.html
/thread/110318 mjanofsky, thanks for that information.
There is a new BIOS version available for your Intel® Compute Stick model. Version 35 can be found here; https://downloadcenter.intel.com/download/26540/Compute-Stick-BIOS-Update-FCBYT10H-86A-?product=8661... Download BIOS Update [FCBYT10H.86A], please give it a try and share your results. I would also like to know if there is a possibility to try newer distro, just like /thread/110318 Gize2 mentioned above.
Thanks Amy and Gize2!
I am going to try some of the tips from the articles posted earlier.
Will Intel support upgrading the Distro? It's going to be a painful process as the internal storage is not large enough to support a direct ubuntu upgrade.
That would be merely a suggestion in case you are willing to try, but officially it is only supported at stock configurations.
Let me know how it goes with the tips.
I also would like to share with you that we have been testing this behavior, but at this stage we have been unable to replicate this. During our tests we found a workaround that might address this, please see it below;
Disabling Power Management:
Wireless cards can have Power Management modes. Switching off power-management can sometimes help.
Thank you for the information. I've been testing another OS on the sticks that is running a newer Linux Core that seems to have resolved the issues.
I'll try disabling the power management tomorrow on another that I have not upgraded and see what happens.
