[SOLVED] wifi connected but no internet access, iwctl doesnt connect

I'm running arch with Kernel: 5.18.7-arch1-1
my wifi suddenly stopped working.. i was able to connect it during the installation and for a short time after rebooting the fresh install..
now it has completely stopped working.. i am able to connect to it but no internet access..
bluetooth and ethernet seems to work fine tho.
i found similar issues on the forum, but the solutions doesnt work..

when i'm connected, ip addr shows

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

ip route shows

output of nano /etc/resolv.conf is

networkctl status -a gives,

Re: [SOLVED] wifi connected but no internet access, iwctl doesnt connect

ahh.. thank you so much!! damn i knew this would be fixed if i were talking to a person who really 'knows' stuff..
running

sudo dhcpcd -d --waitip=4

after installing the driver worked!
feeling silly for not checking whether right drivers were installed..
i'll mark this one as solved..
Thanks seth!!

Re: [SOLVED] wifi connected but no internet access, iwctl doesnt connect

Wowowowowow… don't run multiple network managing services concurrently.
If you want to use networkmanager, you should use networkmanager and not dhcpcd on top of it.
If you want to use dhcpcd as NM backend, see https://wiki.archlinux.org/title/Networ … HCP_client


feeling silly for not checking whether right drivers were installed..

There's no "right" driver and it's common for users to get overwhelmed - broadcom sucks.
https://wiki.archlinux.org/title/Broadcom_wireless (no other vendor needs their personal wiki …)

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
