[Network] [Wifi] Some sites able to ping and others not (google and github e.g.)

Hi everyone!

I am a first time Artix user and post here!

I am having some issue with my wifi connection. I installed Artix with openrc and networkmanager and that got me working with ethernet cable. However, with the wifi connection, I am able to access some sites and not others. For instance I can access google.com but not github.com. Moreover, when I ping these two websites I get these results:

Code: [Select]
[computer name]# ping google.com
PING google.com(2800:3f0:4001:82f::200e (2800:3f0:4001:82f::200e)) 56 data bytes

Seeing this, I would assume that I cannot ping ipv4 domains, but I am not certain of that. What I managed to grasp my head around is that might be a DNS issue. So I tried to install these two packages and set it up a few different ways but with no luck:

Code: [Select]
local/dhclient 4.4.2.P1-1
    A standalone DHCP client from the dhcp package
local/dnsmasq 2.85-1
    Lightweight, easy to configure DNS forwarder and DHCP server

Since I had no success and I am willing to learn more about this issue I decided to post the question here =]

Any help is most certaily appreciated!

Cheers!

Ps.: I would assume that the title is not very good... If I can change it later to be more precise on the problem I will

If wired works fine, then we should rule out a problem in your installation. Look into your router's settings, specifically in the wireless section, if there's an IPv6/IPv4 option disabled somewhere.

Something is wrong in routing.

Post,
Code: [Select]
$traceroute 1.1.1.1

@nous I could not find any setting that might not be enabled for ipv4 or ipv6 on the router. Interesting enough, and forgot to mention on the post before, all other devices are working on wirelesss: cells and another notebook.

@calvinh here is the output

Code: [Select]
[name@computer ~]$ traceroute 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 60 byte packets
 1  192.168.0.142 (192.168.0.142)  198.169 ms !H  198.131 ms !H  198.108 ms !H

Another interesting fact, I could not access the router settings from the wireless. I was able via ethernet though.

wlan0 is not configured properly (wrong ipv4 and multiple ipv6 addresses, wrong default gw). Check your net config in the system and router.

I am not sure what exactly to set up properly. I am very new to this subject. Would mind elaborate bit more on what setting I am looking for?

from what I could understand, since I am using NetworkManager, its internal dhcp client was supposed to be managing the ipv4, ipv6 settings properly for me. But from that I am a bit lost of what is not working as it is supposed to.

I tried to only change the default gateway as well, but nothing changed

Code: [Select]
ip route add default via 192.168.0.1 dev wlan0 # took this from the example in the man

Wait, just noticed this:

Is really your assigned IP address the broadcast address?

Re: [Network] [Wifi] Some sites able to ping and others not (google and github e.g.)

@nous, you nailed it! I changed with the broadcast setting with these two commands and it worked!

Code: [Select]
 ip address add 192.168.0.44/24 broadcast + dev wlan0

Code: [Select]
ip address del 192.168.0.255/24 dev wlan0

However I am failing to made this change permanent. After a few moments the ip address that is the same as the broadcast comes back.

I could not find the file where this information is stored nor the appropriate command. Is there a simple way of making such change permanet?

For starters, try to switch temporarily to connman (remember to disable networkmanager). If it works, then NM settings should be investigated.

Could be the dhcp lease renew request which changes your old ip. If that's the case, either change to use static ip in your system or change the dhcpd settings (most likely in your router, this is preferred solution).
