Acer Aspire v3-772G connectivity issue

Hello!

I'm having an issue I can not understand and I wonder if anyone else experienced something similar. I'm using Acer Aspire V3-772G.

Short version: my computer can not connect to internet (not even to modem) over ethernet cable

What happened is:

One day I got home and saw computer showing me that ethernet cable is unplugged. Same goes to Wi-Fi (it didn't find any network and had cross mark over icon).
First I thought it was cable or modem, so I tested different ports and different cables, noone proved to help. Than I tested all those combinations on different computer, everything worked like a charm.
After some messing around, I've decided to format computer and test it. It didn't work for ethernet, though it worked for Wi-Fi (computer found wi-fi networks).
So I formated and installed Windows on other disk, same story.

Than I saw new BIOS update was out, so I installed it. And apparently it helped - Ethernet connection was possible. Installed drivers and other software I use and everything worked ok.

Today I wake up and I get same issue. Laptop was turned on during night btw.

Funny thing is, just as I was writing this, ethernet port seems to be working again. I'm wondering if I'm doing something wrong or does this sound like hardware issue?

Also if it help, I'm getting blue screen with "Your computer ran into issue" message every 3rd-4th time I startup computer. And computer itself sometimes takes quite a long time at either startup or shutdown - sometimes I don't even see Acer logo at startup.

Here's link to my device manager:


Cheers for any help and enjoy,

This is weird. Make sure that your drivers are up to date - use Broadcom website as reference - not Acer's
Also make sure that any power saving features in WI down power profile and I driver's advanced settings are disabled.

To be honest I don't really believe that any of the above will help but we have to get the most obvious solutions out of the way.

 

Hello and cheers for reply!

I took computer to service and they claim 2nd disk is the issue, since BIOS doesn't recognise it in most of the cases. So I took disk out and tried again....same issue. Going to test disk now to see if there's an issue with it as well and see how it goes from there.
