[Solved: User error] Erroneous OpenDNS address causes undue slowness

Hello.

First of all, I have to remark that I love this distro. I have been away from Crunchbang for a few years and I am really happy to have found Bunsen Labs.

I was experiencing very slow Internet responsiveness and then noticed hangups in DNS lookups in browsers when noodling about on the web. Pages were taking a long time to load and I could see the browsers stalling on the lookup while cached pages loaded quickly.

In troubleshooting the issue I found that in /etc/resolv.conf the following nameservers were listed:

nameserver 208.67.222.22
nameserver 208.67.220.220
nameserver 192.168.1.1

The problem is that the first address is wrong, it should be 208.67.222.222.

Simply editing /etc/resolv.conf isn't persistent, so after adjusted resolv.conf to read:

nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 192.168.1.1

I then added:

dns=none

to the [main] section of /etc/NetworkManager/NetworkManager.conf and rebooted.

After rebooting, the nameservers are correct and thusly web pages and other services now load with appropriate speed.

I'm not sure if the generation of these DNS nameservers is the doing of the distro, though it would be wonderful is this oversight could be corrected in a default install.

Sounds like there may be a bug in the DNS nameservers as presented by your ISP as NetworkManager gets the DNS nameserver information from the ISP. Have you encountered this on any other distro or even in Windows?

Edit: You are correct. I found the problem in my router's configuration. I sincerely apologize for this report.

Great to hear and this could help others who have the same issue to check their router's configuration. If you are using OpenDNS (or even Google DNS) good to doublecheck the nameserver IP's you entered into the router's network configuration page for any typos.

I really appreciate your quick and respectful response to my misplaced and misinformed report.

Beyond pointing out alternative places to look for issues, you actually surfaced a kinda serious problem with my network.

I am truly grateful for that. Thank you.

As an aside, I tried to get a bunch of distros installed on this Ryzen build with no success. I first tried the Bunsen GUI install with no luck, then Fedora, Ubuntu, and Debian testing. The Bunsen installer was the only one that actually presented an interface before failing with a garbled screen, so I went back to that and tried the advanced text install--and voila: I have a beautifully functioning system with the distro I had originally hoped to be running--albeit with the latest kernel.

It feels great to be back.
