[arch-general] Ping: 100% package loss

[Thorsten Jolitz]

Hello List,
sometime age my msmtp imap connections just stopped working.
Investigating the cause, I checked quite a lot of things, and came
across the ping "100% package loss" problem:

With

/etc/resolv.conf
,----
| # Generated by resolvconf
| domain Speedport_W_xxxxxx
| 
| nameserver 192.168.2.1
| nameserver fe80::1%ens34
`----

this works

,----
| $ drill @192.168.2.1. www.google.com

and I can ping the nameserver ip too.

Even when I put Googles DNS Servers in my /etc/resolv.conf, it would not
work.
So what could be the problem here?

TIA
