Hey guys, so I came across a very odd problem, I recently bought a refurbished computer and put Ubuntu 16 onto it. However whenever I connect this computer to my ethernet-switch, after about 10-20 sec everything connected to the switch will no longer connect to the internet or LAN. I have no idea why this happening and any help would be amazing. Thanks in advance.
I guess I fixed the problem, for some reason when I take out my gpu the problem stops, although I have no idea how the gpu would affect my internet connection.

I use Unity (2019.4 LTS) for developing an application for Microsoft HoloLens 2 as the target platform. To do so, I added MRTK (Version v2.5) to my project to use some of the libraries. I regularly get errors in the console that look like this:
[XRInputSubsystem] A device disconnection with the id 2000000037 has been reported but no device with that id was connected.
It seems to happen somewhat randomly. At first, I thought it was disconnecting or something, but then I realized it was just pausing Unity, and I can click 'play' several times to bypass them. This workaround is annoying and slows me down though. Does anyone have an idea for solving this issue?
I solved this error only by increasing the bandwidth of my Internet network. This error happened when my Internet bandwidth was 9MB per second. Now, I use a stronger bandwidth of about 70MB per second and I do not see the same error at all.
I am trying to build a small system which include a rPi and rPi Zero. rPi act as local wifi hotspot and rPi zero connect to rPi hotspot.Then I access zero camera through rPi. My diagram looks like this.
It works totally fine if I have a LAN connection. Once I remove the lan connection motionEyeOs won't stream any data. And even it disconnect from wifi and go to boot loop.
So my question, is there any way we can make motionEyeOs works with out actual internet ?.
The answer to your question: You can set link_watch="false" in /data/etc/watch.conf
But this come with a few other problems:
If your camera boots without network connection (internet), it has no time set (your videos and images could get overwritten)
If your camera boots without or looses network connection (internet), the camera does not try to reconnect and you have no other chance and have to connect a keyboard an monitor to it
A hardware clock would help for the first problem but I am still searching for a solution for the second. If you already have one, I would appreciate it, if you could help me out.

This is what I use for an offline video recorder and it only needs the software and a power source..Camera also but you get the idea. Keep your image (os) small as possible as this can fill an sd card fast. If I remember right, I used 800 x 600 and it would use a gig an hour.
I want to preface this by saying I am learning Raspberry Pi. This is my first real hands on experience. A project I am working on requires our PI-3 to be connected to the internet via a SIM.
We are using the SIM800 Board (https://www.modmypi.com/raspberry-pi/communication-1068/raspberry-pi-sim800-gsm-breakout-board) and a T-Mobile SIM. Please note that the SIM is already activated.
I followed along with this tutorial and used SAKIS3G: https://www.modmypi.com/blog/how-to-connect-your-raspberry-pi-to-a-3g-network. Everything works until the final selection "custom TTY..."
I receive the following error box: "Device did not report GSM capabilities. You can skip this by adding --noprobe command line switch." I have searched high and low for solutions, but there is very limited information. Does anyone here have experience with errors such as this and can point me in the right direction?
I also added the --noprobe suggestion, but it still printed the same error.
I found a work around, hopefully this is useful for someone. Sakis3G seems to be more focused around other SIM card models rather than T-Mobile. I found a really good guide that allows for easy connection (https://www.rhydolabz.com/wiki/?p=16325).
Follow the link's steps and you should be good. The only flaw with this currently is that it requires manual connection every time the pi boots, but this could probably be fixed by someone who knows R-Pi better than me!
Now I face a tricky problem. My Blackberry Classics has a black screen problem. When I connect it to my laptop with USB cable, Blackberry Link can detect it. However when it tried to connect to it, the Blackberry Blend prompted me to set the Allow Connections switch to on on the device. Obviously, I could not do that. I am thinking maybe there is a method to let me connect to the Blackberry 10 through the USB port just like a console port, but I am not sure. Does anyone know about it? Thanks in advance.
Momenitcs does provide a few ways to connect with a device. But generally the device has to be in development mode, which requires interacting with the device which you apparently can't do. The access is also limited to the development user so you could not use it to, for example, access data from installed applications.
About the only thing you can do at this point is use link to backup your data and restore to that phone once repaired, or to a new phone.
Also, since this question is not really suitable for StackOverflow I'm going to flag it for closing. Questions like this properly belong on SuperUser http://meta.superuser.com/questions/4836/what-is-the-difference-between-super-user-and-stack-overflow/4838
Despite working earlier, my socket chat app now refuses to write to socket on the iPhone!
It works fine on the simulator and again, used to run fine on my phone. I don't really know where to start troubleshooting this issue --- just seems weird. My server doesn't detect anything trying to connect.
Any ideas on how to start troubleshooting this?
Thanks tons.
I did run into a problem where using sockets on the iPhone would not open up the cell phone network unless something else opened it first. I had to run an http call to a generic web site first, and then the sockets would communicate normally. Try putting a call, like sendSynchronousRequest, to a generic web site, like www.apple.com, before opening your socket, and see if it works in that case.
I need to stop wasting all you nice peoples' time.
Long story, my friend updated to iOS 5.1. Now the 3G network reads 4G on iOS 5.1. So I turned off my (5.0) wifi to see if mine cell network was "4G" (which, of course, it wasn't).
But yeah, having turned off wifi my app could no longer join my locally hosted server...
I grabbed Charles though, and it looks handy, so thanks for that anyways. Also Owen's comment about the cell network originally made me think about checking my wifi, as my app shouldn't even be using the cell network yet. But I'll keep in mind what you said for the future.
Thanks everybody!
