[SOLVED] Slow Internet after upgrade

Hi!

Yesterday I ran an upgrade of my system (sudo pacman -Syu) but now is the Internet feel really slow. Websites load slowly, torrents have really low speed and pacman can barely download anything at all. Earlier took pacman -Syy just seconds to complete, but now it takes minutes (if it even manages to download all of the repositories. This is how it looks like:

[17:14] daniel@arch ~ $ sudo pacman -Syy

I have tried to get the fastest mirrorlist by running both "rankmirrors -n 6 mirrorlist.backup > mirrorlist" and "reflector -l 5 --sort rate --save /etc/pacman.d/mirrorlist", without any good results.

This is how my /etc/hosts file looks like:

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>    <hostname.domain.org>    <hostname>
127.0.0.1    localhost.localdomain    localhost
127.0.0.1    arch.domain.org        arch

# End of file

And this is my /etc/resolv.conf file:

# Generated by dhcpcd from eth0
# OpenDNS servers
nameserver 208.67.222.222
nameserver 208.67.220.220
# google nameservers
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 195.67.199.27
nameserver 195.67.199.28
nameserver 195.67.199.29
options timeout:1

As I'm pretty new to Arch I'm not really sure what I should do. But I suppose it's not pacman in particular that is the problem, but my Internet configuration in some way, since it's not only pacman that is slow.

Please tell if I need to provide more information.

Re: [SOLVED] Slow Internet after upgrade

Could you provide the parts from /var/log/pacman.log including your update yesterday? If you see a suspicious package related to devices and internet there, you could try to downgrade it.

Re: [SOLVED] Slow Internet after upgrade

I brought my sister's laptop to my room along with her Internet cable, because I was going to download some packages to her computer and then move them over to my computer with an USB memory. But when I had her Internet cable in my room, I thought that I could try to plug it in to my computer just to see if that would work better - and so it did. Apparently my cable is damaged in some way, so I will look into that. I have no idea how this damage could have happened, or how it still can work (but slowly).

Anyway, I'm marking this thread as solved. Thanks for the answer and the views that I got.
