[solved] internet not working and internet periodically disconnecting

still a newbie so not quite sure how to debug please do help out in that regard

context:

im on a relatively new install and it got progressively worse over the last 2 weeks at first i could connect fine to wifi but in sm like 3 days it started to take multiple attempts to authenticate with my home network but stayed stable after around 3 min of trying, after around another week and a half the time to authenticate went to around 40min. my school network and phones hotspot worked fine but today all three stopped working completely both the little indicator from kdeplasma and iwctl station wlan0 show show that my wifi is connected but nothing works on it

ping returns  :Temporary failure in name resolution

please be patient if i get smth wrong as a prb will

Re: [solved] internet not working and internet periodically disconnecting

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
ip a
ip r
dig archlinux.org
dig @8.8.8.8 archlinux.org

Does it still work w/ the LTS kernel?

Re: [solved] internet not working and internet periodically disconnecting

Please use [code][/code] tags. Edit your post in this regard.

disable and stop dhcpcd, iwd and all systemd-networkd* services
If you want to use iwd or dhcpcd w/ NM see https://wiki.archlinux.org/title/Networ … Fi_backend resp. https://wiki.archlinux.org/title/Networ … HCP_client

Report back about the development (w/ the vpn, dnsmasq & firewalld there's obviously opportunity for other problems)

Re: [solved] internet not working and internet periodically disconnecting

In doubt reboot, is the internet there and stable?
Otherwise please post the outputs of

ip a
ip r
dig archlinux.org
dig @8.8.8.8 archlinux.org

and pay attention to the syntax - "@8.8.8.8" is not something where you can randomly drop or replace digits

Re: [solved] internet not working and internet periodically disconnecting

What about

ip a
ip r
dig archlinux.org

?

DNS resolution at googles server works, so it might just be a resolver misconfiguration

cat /etc/resolv.conf

Unstable wifi specifically can also be caused by roaming, we'll see…

Re: [solved] internet not working and internet periodically disconnecting

You're trying to use some resolver on the localhost (eg. dnsmasq) but are blocked from access (firewalld?)

ss -tulpen

and in doubt fix your firewall configuration to allow udp on the local port #53

Not having any resolv.conf is however wild, nm typically writes that - did you https://wiki.archlinux.org/title/NetworkManager#dnsmasq ?

Re: [solved] internet not working and internet periodically disconnecting

i fixed my firewall config
i also checked out the article you sent on 4.7.1.1 it failed saying there was no file

i checked that i had dnsmasq installed (its ver 2.93-1) and i also ran ls on

 /etc/NetworkManager/conf.d/ 

and nothing was listed

Re: [solved] internet not working and internet periodically disconnecting

it failed saying there was no file

What failed??

So after fixing your firewall, can you reach the local resolver?

Also please post the missing command outputs

ip a
ip r
ss -tulpen

Also post your complete system journal for the boot:

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

Re: [solved] internet not working and internet periodically disconnecting

i couldnt find the config file listed in the article (/etc/NetworkManager/conf.d/dns.conf)
there are also just no folders or files under /conf.d/

i thinkk i can reach the local resolver? i reran the older cmd and the new one you sent both seemed to work

Re: [solved] internet not working and internet periodically disconnecting

The implication is to create the file and 8.8.8.8 is google, not the resolver on the localhost…

the journal upload might have failed because of the broken dns.

echo "nameserver 8.8.8.8" | sudo tee  /etc/resolv.conf
sudo chmod 644 /etc/resolv.conf

How exactly did you install archlinux?

Re: [solved] internet not working and internet periodically disconnecting

 tee: /etc/resolv.conf: no such file or directory
nameserver 8.8.8.8
chmod: cannot operate in dangling symlink ‘/etc/resolv.conf’ 

i followed the arch wiki  guide to install arch and also watched a vid with a couple 100 thousand views to help out

At last…

sudo rm /etc/resolv.conf

and then restart NM you've likely been using resolved before and switched to dnsmasq?

Re: [solved] internet not working and internet periodically disconnecting

Your DNS configuration was off. see https://wiki.archlinux.org/title/Networ … management again.
The blue note. You apparently had been using resolved before, now there's dnsmasq but /etc/resolv.conf was/remained a symlink (and apparently pointing nowhere)
This is because resolved depends its behavior on the filetype of /etc/resolv.conf, https://wiki.archlinux.org/title/Systemd-resolved#DNS (which I'm sure someone thought to be a really clever and elegant approach but is actually not)

Removing the stale symlink "allowed" NM proper action.
