[SOLVED] Some websites not working with new wifi

Hey there,

after getting a new internet provider a new router, I can't access some websites, e.g. wireless.wiki.kernel.org or youtube.com, with my Arch Linux setup.
I can't ping those sites either.

> ping youtube.com
ping: youtube.com: Name or service not known

The same sites are working just fine if accessed from any other devices, Windows/Android/etc.
If I'm in a different network, they work as well.
Browsers I've used so far are Firefox and Chromium.

Network controller seems to be installed correctly:

> lspci -k
01:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)
	Subsystem: Intel Corporation Wireless-AC 9260
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi, wl

> dmesg | grep firmware
[    3.342532] iwlwifi 0000:01:00.0: loaded firmware version 46.6bf1df06.0 op_mode iwlmvm
[    3.555383] iwlwifi 0000:01:00.0: Allocated 0x00400000 bytes for firmware monitor.

> dmesg | grep cfg
[    3.243640] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[    3.253395] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'

Content of /etc/hosts is:

127.0.0.1	localhost
::1		localhost
127.0.1.1	archT495.localdomain	archT495

And of /etc/resolv.conf:

> cat /etc/resolv.conf
nameserver 192.168.0.1
nameserver 2a02:8071:3e84:e400:9ec8:fcff:fe3a:5549

192.168.0.1 is the address of the router, and is accessible through my browser.
Is that a known problem? I first suspected the TCP window scaling problem https://wiki.archlinux.org/index.php/Ne … ng_problem, but the fix didn't work for me.

Thanks in advance

Re: [SOLVED] Some websites not working with new wifi

Do you have an IPv4 address?  What is the output of ip addr   ?

Re: [SOLVED] Some websites not working with new wifi

Why do you have two IPs in the same subnet and on the same NIC?

ip r
dig working.domain.com
dig youtube.com

> ip r
default via 192.168.0.1 dev wlp1s0 proto dhcp src 192.168.0.241 metric 304 
192.168.0.0/24 dev wlp1s0 proto dhcp scope link src 192.168.0.241 metric 304

Well funnily enough, after two days and no significant changes, I suddenly reached the sites I weren't able to before, and now I can't reproduce the original issue.

ping -c 3 youtube.com 
PING youtube.com(fra15s28-in-x0e.1e100.net (2a00:1450:4001:80b::200e)) 56 data bytes

Nevertheless, thanks for the help so far, I'm marking this post as solved until I can reproduce it.
