Ethernet not connecting [SOLVED]

Postby Alexiy » Sun Jun 04, 2017 2:20 am

I recently bought a router and linked my PC to it. It was working OK until I needed to run Windows yesterday (on same PC). So, after I done my business on Windows, I restarted back to Mint and it didn't connect to internet. I checked the network with my phone and Windows system - they both connect.
The only clue I have is that when my PC was connected to the network wire directly, sometimes it didn't get IP4 address (while on Mint). But it was easily solvable by toggling connection off and on. Now I don't know what to do. I can not connect my PC to the WAN cable directly anymore, because my ISP has this stupid security check of associating the device MAC address with their database entry or something. My connection is static. I will give you any information you need.

It is not clear from the facts given if Linux Mint can connect to the ISP router, just not the Internet? It sounds like you have a direct cable to the ISP router from the Linux Mint box? Did you try bringing up the router admin interface? Most routers have a web administration interface for the router: typically either http://192.168.0.1/ or http://192.168.1.1/ By default the admin interface doesn't work on wireless, just wired.

My PC is connected to the router via cable.
I can't connect to the web interface, either.

This is weird, I can successfully connect from a laptop (wired) which has Xubuntu 16.04. And in router's interface I can't see my PC in the DHCP client list, which means that it can't connect to router?

I ran ipconfig:

The IP4 address is not being assigned.

Are you using a VPN service. Some people have experienced weird problems like this.

No.
*Sigh* I'm stuck with Windows again.

Screw this, no matter what I try, it doesn't connect to router. I spent almost 2 days on this stuff. I had enough.

Re: Ethernet not connecting [POORLY SOLVED]

Postby Alexiy » Sun Jul 23, 2017 11:30 am

I pinned down this issue a little. So, the issue: I boot into Windows 7; then I boot into Mint 18.1 and lose connection to router and internet. The stupid solution: I boot into old Mint 17.3 system on a separate hard drive and it fixes the connection. What's the problem? Is it kernel, firmware, drivers or something else?

First, when you boot to Windows and then want to boot into Mint, don't restart. Make sure you take Windows all the way down to a power off. Then restart the computer and boot into Mint. Also, make sure that Windows fast booting is turned off. Fast booting is just a type of hibernation and who knows everything that Windows locks when it hibernates. Try these first.

Second, make sure you have installed Samba in Mint 18. (Open the Software Manager, search for "samba", and install "system-config-samba.") By default, Mint 18 does not have Samba installed. I know I had to install Samba in Mint 18 to access network shares. It shouldn't have anything to do with general networking but if you are going to share data between computers, installing Samba will make it easier.

Third, run the following command at a terminal. If you type, the letter F is a capital.

Code: Select all

inxi -Fxz

Post the output back here between code tags. Let's get a look at that networking hardware and drivers.

Finally I've found the solution - it is the asnwer at https://askubuntu.com/questions/596062/ubuntu-14-04-windows-7-pro-dual-boot-cant-connect-to-wired-internet-after-win.
On MBs with Intel adapters like mine, one has to update the driver and uncheck all things in network adapter's power options (Wake on LAN can be left). This leaves the adapter in clean state, thus Linux can use it properly.

I'm glad you got it sorted. Unfortunately Windwoes does this kind of thing with hardware, leaving it in a dirty state.
If your problem is fixed, please mark your thread as [SOLVED] by editing the title of the first message in the thread.
