Re: Desktop cant reach some websites

Could you please do from both computers:

cat /etc/resolv.conf
nslookup www.google.de
traceroute <IP of your dns server / first "nameserver" entry from resolv.conf>
traceroute www.google.de

Re: Desktop cant reach some websites

Desktop = broken, Laptop = fine
cat /etc/resolv.conf

My fritzbox is setup to go to 8.8.4.4, 8.8.8.8 for dns. I dont think it is dns related. Since when i ping i always get the ip.

Desktop

~ cat /etc/resolv.conf                                                                                                                                      13:57  killedbymonkeys@ArchStation

Re: Desktop cant reach some websites

OK, it seems that the connection is ok and the configuration of DNS is always the same.

Are there always the same pages affected from those long loading times? Could you figure out any patterns in that?

Re: Desktop cant reach some websites
