openSUSE LEAP 15 and Comcast Xfinity Internet

English Network/Internet

Hi, everyone.

I’ve been running openSUSE for years and LEAP 15.0 for the last year. I’ve been on DSLExtreme trueExtreme DSL service - which is rebranded AT&T uVerse DSL, with 6Mbs speed for several years with no issues.

Yesterday I had Comcast install their cheap Internet Essentials package of 15Mbs cable Internet with a SMC D3GNV/D3GNV3 Wireless Gateway which is n ARRIS Group, Inc. TG1682G, Hardware Revision: 11.0, running eMTA & DOCSIS Software Version: 10.1.27B.SIP.PC20.CT.

The tech was able to install the device without issue, using his phone app to test the connectivity to the Internet and running a speed test to verify the speed.

However, I was unable to connect to the Internet using Firefox or Chrome browsers, nor can I do ping tests to anything other than the motherboard Ethernet connection and the modem itself. Switching the Ethernet cable back to the DSLExtreme modem and rebooting the system enables Internet again with no problems. Note that I am using Ethernet, not wireless as the tech was doing.

Initially we couldn’t connect to the admin panel on the cable modem. This proved to be an issue with Firefox, since the setting in Firefox that allows for Internet searches from the address block caused Firefox to try to search the Internet for the address 10.0.0.1 when trying to access the cable modem. I finally figured that out - idiocy - and corrected that. Once in the admin section of the cable modem, I saved each and every page of the admin data on to my hard drive for future reference (I do this with any modem as a precaution in case of not being able to access it in the future.) As far as I can tell, all the settings in the cable modem itself seem correct. That and the tech’s ability to access the Internet via wireless would indicate to me that the cable modem is functioning as intended.

I am using Network Manager to manage network connections. I tried switching back to wicked, with no change in the problem. I switched back to Network Manager, still no change. I tried adjusting various settings via Yast both in wicked and Network Manager with no change.

So now I plowed through journald’s logs in an effort to see if there were any error messages of note. I did find these:

Research on the Internet suggested that the issue might be conflict between Network Manager and netconfig both trying to control /etc/resolv.conf with the DNS entries.

Since the two most likely reasons for not being able to reach the Internet are DNS failures and routing failures, I consider these errors to be significant.

Can anyone suggest how I can remove these errors or insure that /etc/resolv.conf has the proper settings in it using Network Manager. I would prefer to use Network Manager over wicked as I like the system panel icon control, particularly since I use to control Private Internet Access VPN settings. Note that I was NOT using PIA at any time in this testing of the cable modem.

I also examined and saved various settings from the system related to networking, which are as follows:

The /etc/resolv.conf from the [NOTE] DSLExtreme version (I’ll have to switch over to Comcast and update this post later with the Comcast version):

### /etc/resolv.conf file autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
#     NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
#     NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
# Note: Manual change of this file disables netconfig too, but
# may get lost when this file contains comments or empty lines
# only, the netconfig settings are same with settings in this
# file and in case of a "netconfig update -f" call.
#
### Please remove (at least) this line when you modify the file!
search attlocal.net linux-2ywh.suse
nameserver 192.168.1.254
nameserver 2602:306:8b12:6ad0::1

And my /etc/sysconfig/network/config with is here at susepaste:

https://paste.opensuse.org/99399057

I figure by comparing these files with the Comcast version that I might be able to pinpoint where the issue is. Can anyone suggest specific places to look for either DNS or routing issues?

Thanks.

I’m doubting that there is anything special about Comcast that would make it difficult to connect.

I am surprised that you have the file “Wired connection 1”, as usually that doesn’t exist unless something was changed from the defaults.

In any case, here is my suggestion.

Reboot. At the “grub” menu, hit the ‘e’ key so that you can edit the boot line.
Scroll down until you react the line that starts “linux” (or maybe “linuxefi”)
Hit the END key to get to the end of that line. Enter “1” (without the quotes). Maybe a space in front of the “1”.

CTRL-X should continue the boot.

This should get you into single user mode. Login as root – I hope you know the password.

And then do:


cd /etc
rm resolv.conf
cd /etc/NetworkManager/system-connections
rm *
cd /var/lib/NetworkManager
rm *

and then reboot with

shutdown -r now

This should reboot back to your desktop as usual.

What I described might sound scary. So let me explain.

The idea is to remove all files that might have configuration related to your previous u-verse setup. Allow NetworkManager to start off fresh with no previous network configuration.

Thanks for your response.

I considered doing that but wanted to wait until I had more information as I didn’t want to hose the working DSL setup along with the Comcast.

However, as it happens, one of the things I did a little while ago was restart the Network Manager service.

Then I was reading a Web page stored as file on my system using Firefox and I thought I would look something up, so, forgetting I was on Comcast with no Internet, I keyed a search term into the search box…and I retrieved it. It took me a moment to realize what I’d done. The Internet was working! I immediately ran a speed test and got the expected result.

So something was broken, but apparently restarting Network Manager fixed it. It might have been something else I did but the only thing I did with regards to settings was run netconfig update -f, after which at some point I did the Network Manager restart.

After discovering the Internet was working, I rebooted to make sure it would continue to work - and it does.

I did notice the following error messages using journalctl from the previous boot, however, which I hadn’t seen before. I’m wondering what they might mean and whether they are connected to the issue I had. They’re only warnings, but they seem serious.

Anyone have any idea what those might mean, whether they might have explained the Internet connection issue, and how I can check to make sure they don’t recur?

When you switched between Wicked and Network Manager, that should have restarted your Network service.
Unknown why that might not have happened or if that isn’t configured as a DHCP client.

In any case,
When your machine is configured as a DHCP client (as your Network Manager connection appears to be), when you restart your network service, it should pick up your new network settings including any name resolution issues which is what @nricker tried to fix with his suggestion.

If you run into this problem again, run the following which should resolve not only any problems restarting Network Manager might fix but other things as well… Basically it forces your machine to contact the network’s DHCP server and requests a brand new lease or to renew an existing elase immediately and retrieves the full network configuration… and it work work regardless of your network connection type or how it’s managed.

systemctl restart network

From this distance, I cannot really tell. But it looked to me as if NetworkManager had remembered the DHCP information from your earlier u-verse network and was still using that stale information.

Yes, restarting NetworkManager should be enough. But that may depend on your home network setup.

In any case, I’m glad things are now working. I would not worry about those “journalctl” messages for now. They might be related to the conditions during the switch over.

OK, thanks all.

I think I did do a restart of the network at some point. Maybe that fixed something. I haven’t seen those error messages since the Internet started working, so I will ignore them unless they recur.
