[SOLVED] Hardware problems related to internet

Post by Falconus »

Earlier today, the internet went down for a couple hours until I reset the router. Once it came back up, I started using Firefox and my Linux Mint 17.3 Cinnamon system crashed. I couldn't move the mouse, and could not get CTRL+ALT+F1 to work. I was forced to hold the power button. This problem persisted every time I booted the computer. I could not successfully boot in safe mode either.

I finally was able to boot using Kernel version 3.16.0-38, as I couldn't get any of the 3.19 series kernels that I was using to work, but my ethernet would not work for more than a few seconds at a time, and my wi-fi was AWOL. The only way that I could get the internet to work at all reliably was by using a USB ethernet adapter that I had gotten for my tablet.

Through a whole lot of experimentation, I realized that the freezing problems seem to be related to the Broadcom driver, which has been working for me successfully for months. Once I uninstalled the drivers related to the wi-fi, everything seemed to work well enough as long as I use the USB ethernet adapter. I cannot get either of the motherboard ethernet jacks to work worth a darn.

I reinstalled the Broadcom driver - it took several attempts - and it finally recognized the wifi again... And froze about 15 seconds later. I had to hold the button in again. I have just disabled the wi-fi without actually uninstalling the driver, and now the ethernet is working again through the USB adapter.

One more problem... Now when I do CTRL+ALT+F1, the cursor just blinks at me until I hit CTRL+ALT+DEL, and the computer restarts. I am expecting to drop out of the GUI and be able to run commands. This no longer works.

While my computer is perfectly functional now with the USB ethernet adapter, all of the on-board internet is not working at all. I do not know whether it is a hardware issue (somehow the built-in internet cards got fried when the internet glitched), or if I have driver/kernel issues. I am now running Kernel 4.2.0-23. Do you have any suggestions for how to proceed?

I really appreciate it, as this motherboard is less than a year old, and I really don't want to be having hardware issues. :cry:

To sum up:
1. Using the on-board Broadcom wifi controller causes the computer to freeze. Only solution is to hold the power button.
2. Neither of the ethernet controllers are reliably connecting to the internet. Sometimes they connect for a few seconds, but that's it.
3. I can use a USB ethernet adapter to connect to the internet. This works well.

This problem was resolved when I reset the UEFI to default settings.
