Internet delay

Amelia Evans · 2022-07-20 14:35:18

Hi everyone!
I have problem with internet...
Every time when I try to open a site, there is delay before connecting
Downloading a package with pacman is the same story
My internet speed is good but the delay before downloading anything is ANNOYING
Please help me...

Sounds like a DNS problem. Once a download starts, is the download speed itself normal?
Did you, per chance, install and configure Avahi?
Wired? Wireless? Is this on a particular network or all networks?
Is this new behavior, or has it never been correct?

Also, how much delay (roughly, in seconds) - 1, 5, 25, …?

Next to avahi issues, please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
resolvectl status
dig heise.de # because you probably never visited this domain, so it's not cached
dig @8.8.8.8 heise.de # 8.8.8.8 is googles DNS server

Yes, download speed is normal
never used Avahi, instead installed and configured Apache
i tried both wired and wireless network and issue is on all networks
It is new behavior, i recently reinstalled archlinux......

I would say, <5sec. delay. The output:

The delay is like this:

What does mean

multi-user.target.wants

?

Local domain? Sorry, I honestly don't know much about this stuff

seth · 2022-07-23 19:03:14

So you by default get a 100ms response from your gateway (router and likely forwarding the DNS configured there) and a 70ms response from google (8.8.8.8) - neither is super-fast but in line w/ your pings.
From the ping results, the generally high latency is however not the problem - the first two responses are massive outliers w/ ~3 and ~10 times the average latency.

What's the output for

ping -c5 _gateway

and do you also get the initial delay when running two pings in parallel?
(ie. open two terminals, run "ping 8.8.8.8" in one and once the response there is down to ~80ms, run "ping 1.1.1.1" in the other terminal and pay attention to the initial response time)

also, i dont get delay when running two pings

seth · 2022-07-24 07:31:09

So on a much lower scale you get the same initial delay from the gateway.
I'd normally blame power saving, but that doesn't fit "wired and wireless", thee first two pings instead of only the first one and also absolutely not the vastly different initial delay when pinging the gateway instead of some IP.
…
Do you have the opportunity to test the system against a different router/AP (office, starbucks, …)?

As a mitigation strategy:
if you keep "ping -q _gateway" running in some terminal, does the original problem ("Every time when I try to open a site, there is delay before connecting") disappear?

Sidebar:

never used Avahi, instead installed and configured Apache

Humm?
https://wiki.archlinux.org/title/Avahi is a service discovery protocol and Apache is a webserver (that's why I asked for your local domain) - they have no relation an if you only installed apache because it sounds(?) like avahi, you should probably get rid of apache again.

ewaller · 2022-07-24 22:20:09

And my only concern of Avahi is that improper removal of it can leave a broken system that tries something that no longer exists first. If it was never installed, the concern is moot.

Achille0072 · 2023-11-14 09:03:16

Hi,
I seem to have the same problem, but it happens only on the university wifi. Also, the problem wasn't there from the start, it only began some weeks ago.
Is there any solution?

Probably not, the thread is 18 months old and the limited condition sounds like it's probably a different issue.
