WLAN problem

hello there,

pretty new to salix, but not to linux in general.

yesterday installed salix on a fuji-laptop, the install went fine and also the wifi connection - I thought :roll:
ping works and some websites opened by firefox (e.g. no salix.org or similar site, but some wikipedia or youtube work)
BUT the salix mirror/sources are not reachable ---> "retrieving packagedata failed to download: could not resolve hostname"
tried several mirrors - no success
if changing to wired connection all works as it should.

does anyone know such issue and how to fix it?

thanks from Germany

What is your wireless card?

Perhaps one of the new kernel 6.18 or 6.12 packages fixes it?

Or maybe it's just DNS?

thanks

wifi card is Realtek RTL8111

did install another kernel -- same behavior, means no update/upgrade/install possible in wifi-connection
also no connection to any site of salix.org

it's a pitty, but a only-wired-connection is not satisfying on a laptop

(sorry, 2nd answer cause the original got lost)

What about my last question? Could it be a DNS issue? What nameservers are you using for your wired and for your wireless connection? What happens if you run something like this when connected to wireless?

Code: Select all

dig salixos.org
And when you say ping works, do you mean it works with an IP, or with a domain name?

Does

Code: Select all

ping 1.1.1.1
work and does

Code: Select all

ping ddg.gg
work with wireless?

don't think it's a DNS problem.
ping works with cloudflare and domains, but no salix......
also DuckDuckGo:
--- ddg.gg ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3005ms
will leave salix on my laptop, as I wrote there is no sense if wifi doesn't work

Can you reach salixos.org from another device in your network?

yes, so I write to your forums from archlinux in dualboot on the same machine wifi connected
with wired connection salix works also
tried three times a new install -- alltimes same result ---> wired YES, wifi NO

I think the Realtek RTL8111 is a widely used Gigabit Ethernet controller chipset, not a Wi-Fi card.

type this to find your wireless card.

Code: Select all

lspci -k | grep -A 3 -i "network"
what is the output of

Code: Select all

iwconfig 
and

Code: Select all

ifconfig

so what is the output of (open a terminal and type)
iwconfig
and
ifconfig
also check if iwlwifi-2030-*.ucode exists

Code: Select all

ls -l /lib/firmware/iwlwifi-2030-*.ucode
check if driver is loaded

Code: Select all

sudo dmesg | grep iwlwifi
If the driver doesn't appear at all, try loading it manually as root:

Code: Select all

sudo modprobe iwlwifi
run nmtui from terminal to connect

Code: Select all

nmtui
Also the "N" protocol often causes disconnections or slow speeds on older drivers.
if this happened to you then as root type

Code: Select all

echo "options iwlwifi 11n_disable=1" > /etc/modprobe.d/iwlwifi.conf
and reload driver without reboot

Code: Select all

sudo modprobe -r iwldvm iwlwifi
sudo modprobe iwlwifi
then enable wifi card

Code: Select all

sudo ip link set wlan0 up
