Mint 18 - connection lost

Post by ennoborg » Sat Jul 02, 2016 7:39 am

This happened in the beta, and I see it in the release version too. I have a Medion desktop PC, connected via ethernet, and occasionally I seem to lose the ethernet connection after an update or something. A restart helps in that case, but I have never seen this phenomenon in 17.3.

My PC has wifi too, but I don't use that.

Any ideas? It's definitely new, and I haven't checked whether ubuntu 16.04 has the same problem, or not. I test that in VirtualBox.

Follow-up: I have this with LMDE Betsy too.

When I first tried LMDE after they went stable I had same issue basically. Only it saw my wifi for about two minutes. Was able to get on but not later. Got peed and tossed on an old version of Wheezy then later Mint. So just this weekend I installed LMDE2 Betsy Mate just for hell of it to see what would happen. During this time I was hooked up with cable. Did the upgrades. Was worried what would happen. Disconnected my cable after all the upgrades were done. It saw my wifi along with several others to choose from. I got it running and haven't had any issues since then. So, I'm wondering and probably a stupid question to toss at you but were you hooked to the cable first and got all the upgrades after install?

This is my 3rd day after a clean install from Linux Mint 17.3 Cinnamon to 18. Today, I'm seeing the same thing as the OP with my wired Ethernet connection. I rebooted 4 times this morning and Mint only saw the Ethernet connection on two of them. Any suggestions on where to start troubleshooting this?

Can confirm. I'm running Mint 18 mate from an upgrade of 17.3 (64 bit).

Everything works fine, I come back some hours later, and suddenly I have no internet. Wifi still shows connected in the tray by the clock, but I can't ping out, surf, no upstream connectivity at all.

I have to reboot. Every. Day.

Pretty annoying. Devuan does not have this issue, so I'm guessing it's more upstream systemd bull%&@.

Let me know if there's a solution, or a more stable version of mint without systemd. My other Mint 18 machine occasionally crashes too, which has never happened before.

I noticed the same instability and broken stuff in Debian 8 when they took the d. So I'm not at all surprised. Just: Disappointed.

Just found this thread.

Can confirm the same for me - no issue with 17.3, but with 18 randomly no internet, restart fixes it for days. My system never shuts off.

Not my router or modem as it keeps working with my other computer. Have not found solution other than a restart.

Since a few of the posters with ethernet issues are using the same driver e1000e, someone might want to try installing the latest from Intel

I'm using the latest e1000e driver from Intel and the problem still persists, after a while we lose IPv4 connectivity, IPv6 is still active and operational. After a restart of the network services both IPv4 and IPv6 are again operational. I can be wrong but have the impression that after a network services restart IPv4 keeps operational for a longer time, cannot test since i shutdown my laptop every day, also from time to time i'm using Windows10 which is also installed on the same laptop but on another physical hard drive(2 hard drives in this laptop)

I cannot do further tests since i currently have no access to my laptop.

Are you using TLP or UFW? TLP is a power management program and UFW is a firewall program

Well I can answer that - Yes I am using UFW. Why? Do you think that may be interfering? Just as a FYI, I was using UFW in 17.3 and never had the issue.

Also, just as a side note, I have not had the problem crop up since I updated to the 4.4.0-45.66 kernel. Thing is, the problem would happen so rarely (many days could go by without a disconnect) that it is impossible to know if the new kernel actually dealt with the issue.

Watch the dmesg logs for items concerning UFW

Code: Select all

dmesg | grep -i ufw
I have seen UFW block necessary traffic and cause issues

i have UFW installed but not active, i don't have TLP installed.
I've lost IPv4 connectivity only once a couple of days ago, last 2 days all is working fine, have to admit that lot of packages have been updated recently, i'm also running latest kernel now Version: 4.4.0-47.68

will monitor and give feedback

I haven't had it happen since the 4.4.0-45.66 kernel. Not sure if that is coincidence or cause and effect, but either way the issue seems done with.

I've finally solved my IP connection lost problem. I was able to reproduce every time just by booting first in Windows 10 followed by a restart in Mint 18, after a while Mint looses IP connectivity.

Mint 18 maintains the hardware clock (RTC, real time clock) in universal time (UTC) by default while Windows maintains the clock in local time, thus causing time conflicts between Mint and Windows.

To fix it, make Windows uses UTC.
boot into Windows 10, when you’re in, do:

go to Start Menu, search for and launch cmd as Administrator.
When the command console opens, paste below command to create a DWORD value to the registry:
Reg add HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation /v RealTimeIsUniversal /t REG_DWORD /d 1

For 64-bit Windows, use a QWORD value instead:
Reg add HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation /v RealTimeIsUniversal /t REG_QWORD /d 1

I've been using the following Ubuntu Howto document:
http://ubuntuhandbook.org/index.php/201 ... indows-10/

Now the hardware clock is always set to UTC by Mint and Windows 10
Due to above fix Mint 18 does no longer loose IP connectivity
